More Details on Our Top Picks
Schultz Liquid Plant Food Plus (10-15-10)
Schultz Liquid Plant Food Plus earns its spot as the best overall due to its all-purpose 10-15-10 formula, suitable for a broad range of plants both indoors and outdoors. Its simplicity—requiring just 7 drops per quart—makes it highly convenient for regular feeding, especially during transplanting or rooting phases. Compared to the more specialized options like the Organic Liquid Sea Kelp Fertilizer, it may lack organic certification but offers consistent results for general use. The main tradeoff is its need for precise measurement; over-application or underdosing can impact plant health. Its limited size means frequent refills, but its versatility and ease of use make it a reliable choice for most gardeners. This pick makes the most sense for those seeking a straightforward, all-around fertilizer without complex mixing or multiple products.
Pros:- Easy to use with just 7 drops per quart of water
- Suitable for a wide range of plants and environments
- Encourages healthy growth and rooting
Cons:- Requires careful measurement for optimal results
- Limited size necessitates frequent refills
- Some users may prefer organic alternatives
Best for: Gardeners who want a simple, reliable fertilizer for a variety of plants, both indoors and outdoors.
Not ideal for: Organic gardeners or those preferring a more natural approach, since it contains synthetic nutrients and a small size.
- Brand:Schultz
- Model Number:S-1011
- UPC:885343146529
- Item Type:Plant Fertilizer
- Size:4 Fluid Ounces
- Application:Indoor and outdoor plants
Our verdict“This fertilizer suits those seeking a straightforward, all-purpose option for diverse gardening needs.”
Organic Liquid Sea Kelp Fertilizer for Plants, 4oz, Makes 24 Gallons
This organic kelp-based fertilizer differentiates itself through its Maine-harvested seaweed origin, offering a natural boost for plant resilience. Its concentrated formula—just 1 teaspoon per gallon—makes a significant amount of nutrient-rich solution, ideal for those who want organic, eco-friendly options. While it excels at promoting strong roots and stems, its liquid-only format means frequent applications may be necessary to maintain consistent feeding, especially for heavy feeders or large plants. The limited 4 oz size can be a drawback for larger setups, but its simplicity and organic certification make it appealing for eco-conscious gardeners. Unlike synthetic options like Miracle-Gro Indoor Plant Food, this supports organic gardening practices, though it may require more careful measurement and more frequent use to sustain growth.
Pros:- Supports strong roots and stems naturally
- Made from high-quality Maine seaweed ensuring purity
- Easy to mix without powders or scales
- Suitable for organic gardening
Cons:- Limited to 4 oz size, requiring frequent reapplication
- Concentrated formula needs precise measurement
- Liquid form may require more frequent use
Best for: Organic gardeners or those who prefer natural, environmentally friendly fertilizers for indoor and outdoor plants.
Not ideal for: Gardeners seeking large quantities or low-maintenance solutions, since the small size and need for frequent application can be inconvenient.
- Volume:4 oz
- Makes:24 gallons
- Nutrient Content:4% soluble potash (0-0-4)
- Harvested In:Maine, USA
- Application:Add 1 teaspoon per gallon of water
- Suitable For:Indoor & outdoor plants, transplants
Our verdict“Ideal for organic growers wanting a natural, concentrated kelp fertilizer, with the understanding it needs regular, careful application.”
GARDENWISE 10-10-10 All Purpose Plant Food – Liquid Fertilizer with Seaweed, Kelp & Iron – Indoor & Outdoor
GARDENWISE’s 10-10-10 formula strikes a balance that appeals to gardeners needing a single solution for various plants—from vegetables to lawns. Its enrichment with seaweed extract and chelated iron enhances overall vitality and foliage color, making it a strong contender against more specialized products like the Miracle-Gro Indoor Plant Food. While the 8 oz size is somewhat limiting—requiring frequent reordering—it offers a comprehensive nutrient profile that supports vibrant growth and yield. Its liquid application simplifies feeding, but the specific ratio means it’s less tailored for plants with unique nutritional needs. This makes it ideal for gardeners who prefer a balanced, all-purpose formula that can handle multiple plant types in one regimen.
Pros:- Balanced 10-10-10 nutrient ratio suitable for many plants
- Enriched with seaweed extract and chelated iron for lush growth
- Easy to dilute and apply for indoor and outdoor use
Cons:- Limited to 8 oz, requiring frequent purchases
- Not suitable for organic gardening
- Specific to liquid use only, not granular
Best for: Home gardeners seeking a versatile, balanced liquid fertilizer for diverse plant collections.
Not ideal for: Those needing organic options or long-term feeding solutions, as it relies on synthetic nutrients and small bottle size.
- Nutrient Ratio:10-10-10
- Volume:8 oz
- Enriched With:Seaweed extract, chelated iron (6%)
- Application:Dilute with water and water plants
- Made in:USA
Our verdict“A practical, balanced liquid fertilizer ideal for gardeners managing multiple plant types in one program.”
Miracle-Gro Indoor Plant Food for All Plants, 8 fl. oz. (2-Pack)
This two-pack of Miracle-Gro Indoor Plant Food offers a straightforward way to keep houseplants healthy, with a formula designed for a wide range of indoor species. Its convenience lies in the ability to apply directly or mix with water every two weeks, making it suitable for busy gardeners. Compared to the Schultz Liquid Plant Food Plus, it provides a more frequent feeding schedule, which can be beneficial for rapid growth but may also require more attention. The main tradeoff is its synthetic chemical content, which might not appeal to organic enthusiasts. Its 8 oz bottles are manageable, but the need for regular reapplication means ongoing purchase. It’s best for those who want a dependable, easy-to-use indoor fertilizer with consistent results.
Pros:- Suitable for a variety of indoor plants, including flowers and herbs
- Easy to apply directly or mixed with water
- Provides essential nutrients for healthier indoor plants
Cons:- Requires reapplication every two weeks
- Limited size, needing frequent repurchase
- Contains synthetic chemicals, not organic
Best for: Indoor gardeners who want a reliable, easy-to-apply fertilizer for frequent use on houseplants, flowers, and herbs.
Not ideal for: Organic gardeners or those seeking long-lasting, less frequent feeding options, as it requires bi-weekly reapplication and contains synthetic ingredients.
- Brand:Miracle-Gro
- Model Number:3422802
- Quantity:2 bottles of 8 fl. oz.
- Application:Direct to soil or mixed with water
- Frequency:Every 2 weeks
Our verdict“A dependable choice for indoor plant enthusiasts who prefer bi-weekly feeding with minimal fuss.”
Miracle-Gro Liquid All Purpose Plant Food, 32 oz
Miracle-Gro’s 32 oz liquid concentrate offers a broad-spectrum feeding solution that can be used on almost any plant type, from vegetables to shrubs. Its large size makes it suitable for gardeners with multiple plants, providing quick, visible results when used as directed. Compared with the smaller Miracle-Gro Indoor Plant Food, it’s more cost-effective for extensive use and outdoor applications. However, the concentration of chemicals and frequent reapplication—every 1-2 weeks—may be less appealing to organic or low-maintenance growers. Its versatility and ease of mixing make it a go-to for rapid feeding, but careful handling is required due to its concentrated nature. This product is ideal for those needing quick results across many plants, indoors or out.
Pros:- Suitable for a wide range of plants and environments
- Provides quick, visible nourishment
- Large volume offers good value for extensive use
Cons:- Requires frequent reapplication every 1-2 weeks
- Contains synthetic chemicals that may not suit organic practices
- Concentrated formula needs careful handling
Best for: Gardeners managing diverse plant collections who prioritize quick, consistent feeding and large-volume options.
Not ideal for: Organic gardeners or those preferring less frequent, slow-release feeding, as it demands regular reapplication and contains synthetic chemicals.
- Brand:Miracle-Gro
- Model Number:1001501
- Volume:32 oz
- UPC:073561001502
Our verdict“Excellent for those needing rapid, versatile feeding across many plants but with the caveat of frequent reapplications and chemical content.”
Miracle-Gro Pour & Feed Plant Food, 32 fl. oz.
This ready-to-use liquid fertilizer stands out for its simplicity and broad applicability, making it ideal for busy gardeners who want quick results. Unlike the more specialized organic options, it feeds both indoor and outdoor container plants without any mixing, which saves time and effort. However, its frequent application schedule—every 10-14 days—may be inconvenient for those seeking low-maintenance solutions. Compared with products like the Organic Liquid Indoor Plant Food, it lacks detailed nutrient composition, which might concern growers seeking specific formulations. Its strength lies in ease of use and versatility, but it’s less suitable for those with a preference for organic inputs or long-lasting feeding intervals.
Pros:- Simple to apply directly to soil without mixing
- Suitable for both indoor and outdoor container plants
- Promotes healthy, strong plant growth
Cons:- Requires frequent application every 10-14 days
- Limited to container plants, not for garden beds
- No detailed nutrient breakdown provided
Best for: Home gardeners who want quick, straightforward feeding for container plants without fuss.
Not ideal for: Organic gardeners or those seeking slow-release or long-term fertilization, since it requires frequent application and has no detailed nutrient info.
- Brand:Miracle-Gro
- Model Number:1006002
- Volume:32 fl. oz.
- Application:Indoor and outdoor potted plants
- Feeding Frequency:Every 10-14 days
- Type:Pour and Feed Liquid Plant Food
Our verdict“This product is best for gardeners who prioritize convenience and quick results in container gardening.”
Organic Liquid Indoor Plant Food, 5-5-5 NPK, 8oz
This organic formula with a 5-5-5 NPK ratio makes it perfect for indoor growers seeking balanced nourishment. It combines sea kelp and micronutrients to foster lush foliage and healthy roots, outperforming synthetic fertilizers in environmental safety. Compared to the Miracle-Gro Organic Plant Food, it offers a more immediate effect and is odor-free, appealing to those sensitive to smells. On the downside, it needs regular applications to maintain results, which might be a drawback for low-maintenance plant care. This makes it ideal for indoor plant enthusiasts who want a safe, organic option that encourages vibrant growth without synthetic chemicals.
Pros:- Balanced 5-5-5 organic formula supports healthy growth
- Instant-acting and easy to dilute with water
- Contains sea kelp and micronutrients for robust health
- Odor-free and eco-friendly
Cons:- Needs frequent reapplication for sustained effects
- Limited to indoor and tropical plants, not suitable for outdoor garden beds
Best for: Indoor gardeners who prefer organic, balanced feeding with immediate results.
Not ideal for: Growers needing highly specific nutrient ratios or infrequent feeding schedules, as it requires regular applications.
- NPK Ratio:5-5-5
- Volume:8oz
- Treats:up to 50 gallons
- Main Ingredients:Sea Kelp, Micronutrients
- Application:Mix with water or apply directly
- Suitable for:Indoor plants, tropicals, herbs, vegetables
Our verdict“This fertilizer is well-suited for indoor plant lovers seeking a safe, balanced organic boost that works quickly.”
Organic Liquid Kelp & Seaweed Extract Prop Drop (Ecklonia Maxima)
This concentrated kelp extract excels at stimulating root growth and strengthening foliage, making it a popular choice for propagation, cuttings, and seedlings. Its natural root hormones outperform many synthetic options, especially in water propagation or hydroponic systems like LECA. Compared with the Organic Liquid Indoor Plant Food, it offers a more targeted approach for root development rather than general feeding. Its main tradeoff is the need for careful measurement; overuse can lead to root burn or excess algae growth. The highly concentrated formula makes it particularly economical for large volumes, but frequent reordering might be necessary for extensive gardens. It’s ideal for growers focusing on healthy roots and vigorous propagation.
Pros:- Promotes strong root development and vigorous growth
- Suitable for water propagation, soil, hydroponics, and semi-hydro systems
- Organic and non-burning formula safe for daily use
- Highly concentrated and economical
Cons:- Requires precise measurement to avoid overuse
- Strong smell due to natural ingredients
- Limited to 8oz, may need frequent reordering
Best for: Propagators and hydroponic growers seeking natural root stimulation and healthy plant establishment.
Not ideal for: Gardeners looking for a comprehensive fertilizer for mature plants, as this is primarily a root and growth booster.
- Volume:8 oz
- Treats:up to 55 gallons
- Organic:Yes
- Plant Types:Houseplants, tropicals, seedlings, flowers, vegetables
- Application:Water propagation, soil, hydroponics, semi-hydro, LECA
Our verdict“This product is ideal for those focusing on root health and propagation, especially in hydroponic or water-based systems.”
VIVOSUN Liquid Nutrients Base A & B Bundle, 32oz each
The VIVOSUN A & B bundle delivers a comprehensive set of macro and micronutrients, making it suitable for growers who want a full-spectrum feeding program. Unlike the single-product options, this duo supports plants through vegetative and flowering stages, with compatibility across soil, hydroponics, and aquaponics. The main tradeoff is the need to mix the two formulas separately, which could be less convenient for quick feedings. Its strength lies in delivering balanced nutrients for a range of media, but overfeeding is a risk if concentrations aren’t carefully measured. This makes it a strong contender for serious growers managing multiple plant types or growing media.
Pros:- Provides complete macro and micronutrients
- Compatible with soil, hydroponics, aquaponics
- Supports growth from vegetative to flowering stages
- Easy-to-dilute water-soluble formulas
Cons:- Requires separate mixing of A and B formulas
- Concentrated, so overfeeding can occur without care
Best for: Experienced growers needing a customizable, balanced nutrient system for various cultivation methods.
Not ideal for: Beginners or casual gardeners who prefer pre-mixed, ready-to-use solutions, as it requires careful handling and mixing.
- Brand:VIVOSUN
- Item Count:2
- Volume:32 oz each
- Supports:Vegetative and flowering stages
- Compatibility:Soil, hydroponics, aquaponics
Our verdict“This bundle suits experienced growers seeking flexible, balanced nutrition across different growing media.”
Miracle-Gro Organic Plant Food, 32 fl. oz.
This organic liquid fertilizer from Miracle-Gro emphasizes a high percentage of plant-based ingredients, appealing to eco-conscious gardeners. It can be diluted to feed approximately 10 medium plants over a season, making it a cost-effective choice for those seeking long-term organic nutrition. Compared with the Organic Liquid Indoor Plant Food, it covers outdoor garden needs more extensively, but requires frequent reapplication—every 7-14 days—to sustain growth. Its main advantage is its OMRI listing and organic certification, but the need for regular re-dosing may be less appealing for low-maintenance growers. It’s best for gardeners committed to organic practices who want a versatile, sustainable fertilizer for outdoor or combined use.
Pros:- Made from 94% plant-based ingredients
- Suitable for both indoor and outdoor use
- Feeds up to 10 medium plants for around 3 months
- OMRI Listed for organic use
Cons:- Requires dilution before application
- Needs reapplication every 1-2 weeks for best results
Best for: Organic gardeners managing outdoor or mixed-use plants who want a sustainable feeding option.
Not ideal for: Indoor growers seeking fast-acting or less frequent feeding solutions, due to its reapplication schedule.
- Quantity:32 fl. oz.
- Feeding Capacity:up to 10.75 gallons
- Application Frequency:Every 7-14 days outdoors, biweekly indoors
- Organic Certification:OMRI Listed
Our verdict“This organic fertilizer is well-suited for eco-minded gardeners seeking steady, long-term outdoor or mixed-use feeding.”
Indoor Plant Food, Complete Liquid Fertilizer for Houseplants, 8oz
This liquid fertilizer excels at supporting a wide range of indoor plants, making it a flexible choice for plant parents who want a reliable, all-in-one solution. Compared with the Bonide 10-10-10, this formula emphasizes gentle, weekly feeding with a kelp-enriched blend that promotes lush foliage and strong roots without overwhelming sensitive plants. Its ease of mixing and application during regular watering simplifies routine care, although it requires consistent use to see sustained results, which could be a drawback for casual gardeners. Its all-purpose nature makes it suitable for monstera, pothos, and peace lilies, but it’s limited to indoor environments and may not be enough for demanding or outdoor plants.
Pros:- Promotes healthy, lush indoor plants with vibrant foliage
- Easy to mix and apply during watering routines
- Suitable for a wide variety of indoor plants
- Kelp-enriched formula supports plant growth naturally
Cons:- Requires regular weekly use for best results
- Limited to indoor plants only, not suitable for outdoor gardens
Best for: Indoor plant enthusiasts seeking a gentle, all-around fertilizer for multiple houseplant types
Not ideal for: Gardeners needing fertilizer for outdoor or demanding plants requiring higher nutrient levels
- Brand:TPS NUTRIENTS
- Model Number:43634283839737
- Size:8 Fluid Ounces
- UPC:857611006521
- Item Highlight:Encourages New Growth, Kelp-Enriched Formula
- Application:Liquid concentrate, gentle for weekly feeding
- Suitable for:All indoor plant varieties
Our verdict“This pick makes the most sense for indoor gardeners seeking a balanced, easy-to-use fertilizer to keep their plants thriving.”
Liquid Plant Food – Fertilizer for AeroGarden & Hydroponic Systems, 8 oz
This formula is designed specifically for hydroponic setups like AeroGarden, supporting vigorous root development and steady growth in controlled environments. Unlike the all-purpose indoor fertilizer, this product’s reservoir-safe formula minimizes clogging and makes refills straightforward, which is a significant advantage for hydroponic growers. Its focus on root health and compatibility with reservoir systems makes it less suitable for traditional soil-based gardening, and the 8 oz size may require frequent refills for larger or multiple systems. For those using hydroponics, it provides reliable, balanced nutrients, but casual indoor plant owners with soil might find it too specialized and limited in quantity.
Pros:- Supports healthy plant growth and robust root development
- Easy to mix and use within hydroponic reservoirs
- Suitable for herbs, greens, and other indoor plants
- Reservoir-safe formula prevents clogging
Cons:- Designed specifically for hydroponic systems, not soil gardening
- Limited to 8 oz size, requiring frequent refills for larger setups
Best for: Hydroponic growers and indoor gardeners using AeroGarden or similar systems
Not ideal for: Soil-based indoor or outdoor gardeners seeking a general-purpose liquid fertilizer
- Brand:TPS NUTRIENTS
- Model Number:LIQUIDPF8OZ
- Item Highlight:Complete Nutrition for Strong Growth
- UPC:850048592056
- Unit Count:8 Fluid Ounces
- Number of Packs:1
- Supports:Veggies & Herbs
Our verdict“This fertilizer is ideal for hydroponic enthusiasts needing a reliable nutrient source compatible with reservoir systems.”
Miracle-Gro Indoor Plant Food, Liquid Fertilizer for Houseplants, 8 oz., 2-Pack
This two-pack offers a straightforward option for indoor plant care, delivering instant nutrients that boost growth and color. Compared with the more specialized Bonide 10-10-10, Miracle-Gro’s formula emphasizes quick, visible results, making it suitable for those who want to maintain vibrant, healthy houseplants with minimal fuss. The dual-pack offers good value but requires weekly applications to sustain growth, which might be burdensome for busy plant owners. Its versatility across various houseplants makes it a popular choice, though demanding or very sensitive plants might need additional, tailored feeding to thrive long-term.
Pros:- Provides instant nutrients for rapid plant response
- Easy to apply directly or mix with water
- Two-pack offers long-lasting value
- Suitable for a broad range of houseplants
Cons:- Requires weekly application, which can be time-consuming
- May necessitate additional fertilization for high-demand plants
Best for: Homeowners looking for quick, reliable nutrition to keep their indoor plants vibrant
Not ideal for: People with demanding or sensitive plants needing precise, slow-release feeding
- Brand:Miracle-Gro
- Model Number:3037202
- Number of Packs:2
- Item Count:16 Fluid Ounces
- UPC:016027565538
- Included Components:Miracle-Gro Indoor Plant Food (2 bottles)
Our verdict“This fertilizer works well for those wanting quick, noticeable improvements in their indoor plants and good value for money.”
Bonide Houseplant Liquid Plant Food 10-10-10, 8 oz Concentrated Fertilizer for Indoors
Designed for indoor plants that need careful, balanced feeding, the Bonide 10-10-10 offers a concentrated formula that lasts through multiple applications when measured precisely. This makes it a good option for dedicated indoor growers who prefer control over their fertilization routine, especially for orchids, succulents, and ferns. Compared to the more general Miracle-Gro, this product’s focus on a balanced 10-10-10 ratio ensures steady, uniform growth but requires accurate measurement and careful application, which could be a challenge for beginners. Its synthetic nutrients provide reliable results but may not appeal to those seeking organic options or more gentle formulations.
Pros:- Concentrated formula provides multiple applications from a small amount
- Balanced 10-10-10 ratio supports steady growth
- Easy to incorporate into regular watering routines
- Suitable for orchids, succulents, and ferns
Cons:- Requires careful measurement for optimal results
- Contains synthetic nutrients, which may not suit organic gardeners
Best for: Experienced indoor gardeners seeking precise, balanced fertilizer for a variety of houseplants
Not ideal for: Beginners or casual gardeners who prefer pre-measured or organic options
- Brand:Bonide
- Model Number:108A
- Size:8 oz
- Nutrient Ratio:10-10-10
- Application:Use when watering
- UPC:037321001089
Our verdict“This product suits experienced indoor growers who want controlled, consistent feeding with a concentrated formula.”

Factors to Consider When Choosing Liquid Plant Food
Choosing the right liquid plant food involves understanding your plants’ specific needs and your gardening setup. The following factors can guide your decision, helping you avoid common pitfalls and select a formula that delivers consistent results.Nutrient Balance and Formulation
Look for a liquid plant food with a balanced NPK ratio that matches your plant’s growth stage. For example, higher nitrogen promotes leafy growth, while phosphorus supports roots and flowering. Organic options often contain natural ingredients like seaweed or fish emulsion, which can improve soil health over time. Avoid overly concentrated formulas that might cause nutrient burn, especially if you’re a beginner.
Ease of Use and Application
Simplicity matters, especially for regular feeding. Pre-measured bottles, quick-dilution instructions, and clear labels make application easier and reduce waste. Products designed for specific systems—like hydroponics or AeroGarden—may require different formulations. Consider whether you prefer a concentrate to mix or a ready-to-use formula for convenience.
Plant Compatibility
Different plants have different nutrient needs; some formulas are optimized for indoor houseplants, others for outdoor gardens or hydroponics. Check product labels to ensure compatibility with your plant types. Using a formula designed for specific conditions can improve growth and reduce the risk of overfeeding or deficiencies.
Price and Value
Concentrated formulas often provide better value per use but require accurate dilution. Conversely, ready-to-use products may cost more upfront but save time and reduce measurement errors. Consider your budget and how often you plan to feed your plants when choosing a product. Sometimes spending a bit more initially yields better long-term results.
Additional Features
Features like organic ingredients, eco-friendly packaging, or formulations tailored for specific growth stages can influence your choice. Think about whether you want a product that supports organic gardening or one that promotes rapid growth. Also, check if the product is suitable for different watering systems or if it’s designed for specific plant health concerns like flowering or root development.
Frequently Asked Questions
Can I use liquid plant food for all types of plants?
Most liquid plant foods are formulated to be versatile and suitable for a wide range of plants, but it’s important to check the label. Some formulas are tailored specifically for indoor houseplants, while others are designed for outdoor gardens or hydroponic systems. Using a product suited to your plant type can ensure optimal growth and reduce the risk of overfeeding or deficiencies. When in doubt, select a balanced, all-purpose formula for mixed plant collections.
How often should I feed my plants with liquid fertilizer?
Frequency depends on the plant species, growth stage, and the concentration of the fertilizer. Typically, most plants benefit from feeding every 1-2 weeks, but overfeeding can cause stress or nutrient burn. Always follow the manufacturer’s instructions and consider reducing frequency if your plants show signs of excess nutrients, such as yellowing leaves or burnt tips. Organic formulas might require more frequent application to maintain steady growth.
Is organic liquid plant food as effective as synthetic options?
Organic liquid plant foods can be very effective for promoting healthy, natural growth, especially over time. They often contain micronutrients and beneficial compounds that improve soil health and plant resilience. However, they may act more slowly than synthetic fertilizers, requiring more frequent applications. Your choice depends on whether you prioritize natural ingredients or faster results, but both can support thriving plants when used correctly.
Can I use liquid plant food in hydroponic systems?
Yes, many liquid fertilizers are formulated for hydroponics, providing soluble nutrients that plants can absorb directly through their roots. When selecting a product, check if it’s compatible with water-based systems and whether it contains the necessary minerals. Precise dosing is critical in hydroponics to prevent imbalances, so follow dilution instructions carefully. Some formulas are specially designed for hydroponic use, offering better performance in such setups.
What are the key signs I need to adjust my feeding routine?
Signs of nutrient deficiencies include yellowing leaves, stunted growth, or poor flowering. Conversely, overfeeding can lead to leaf burn, wilting, or excessive salt buildup in the soil. Regular observation of your plants will help you catch these symptoms early. Adjust your feeding schedule or concentration accordingly, and consider testing your soil or water to identify specific deficiencies or excesses for more targeted care.
