Best Nitrogen Fertilizer For Plants for Gardens and Lawns

#1 · Best Overall

1. The Grow Co Urea Fertilizer

• Form: Granules
• Weight: 5 lb

Best for: High-nitrogen granules for broad gardens.

Why it ranks #1: Its 46-0-0 ratio gives a clear, concentrated nitrogen specification, and the 5-pound granular product is listed for grass, vegetables, fruits, and flowers.

A 46-0-0 nitrogen ratio is the defining feature of The Grow Co urea, supporting buyers seeking a high-nitrogen feed for grass, vegetables, fruits, and flowers. Its granular form and five-pound quantity suit gardeners handling multiple plant types and aiming for greener leafy growth.

The 46-0-0 ratio identifies this as a high-nitrogen product, while its listed uses cover lawns and a broad range of garden plants. That combination can help buyers address nitrogen needs across mixed plantings without choosing a separate product for each listed plant category. The five-pound quantity provides more material than small-format options, and granules offer a dry format for handling. The supplied information does not give an application rate or schedule, so follow product directions where available.

Skip it if you need a stated application schedule before buying; TPS Nutrients Nitrogen for Plants lists a liquid format instead.

This is a fit for gardeners wanting a high-nitrogen granular feed across lawns, vegetables, fruits, or flowers. Its 46-0-0 ratio is clear, but buyers who need a supplied rate and timing should choose a product with those directions stated.

#2 · Best Large Granules

2. Cz Garden Supply Urea

• Form: Granules
• Weight: 0.1 milligrams

Best for: Urea granules for garden and craft use.

Why it ranks #2: This 5-pound, water-soluble 46-0-0 urea is described for indoor and outdoor flowers, lawns, and garden vegetables, with resealable packaging.

A 46-0-0 urea formula that also serves tie-dye and batik projects sets Cz Garden Supply apart from plant-only nitrogen options. The water-soluble granules are listed for indoor flowers, lawns, vegetables, fruit, and gardens, making them relevant to varied household uses.

The 46-0-0 analysis makes the nitrogen emphasis explicit, while the water-soluble granules are described for indoor flowers, lawns, and garden vegetables. That range can suit a gardener managing several plant types, and the stated tie-dye and batik use adds a separate craft application for buyers interested in both. The resealable, easy-pour packaging supports storing and dispensing the granules between uses. The supplied directions give a 4–6 week interval, with application as directed to wet or dry soil.

Skip it if you need a small package for container gardening; Down To Earth Blood Meal 12-0-0 is listed in a 0.5-pound size.

Choose Cz Garden Supply if you want 46-0-0 urea for a range of garden plants and value its stated craft use as well. The listed five-pound application guidance may be cumbersome for small plots or occasional container feeding.

#3 · Best Water-Soluble

3. RAW Nitrogen Fertilizer

• Form: Powder
• Weight: 2.08 oz

Best for: Water-soluble feed for vegetative growth.

Why it ranks #3: The water-soluble powder lists 20% ammonium nitrogen and is formulated for leaf and stem development, suiting feeding programs that need a soluble option.

A water-soluble powder containing 20% ammonium nitrogen gives RAW Nitrogen a clearly stated role in supporting leaf and stem development. Its vegetable focus and ability to integrate into feeding programs make it a compact option for growers who want targeted nitrogen during vegetative growth.

The 20% ammonium nitrogen specification gives buyers a concrete nutrient detail, while the water-soluble powder format supports fitting it into an existing feeding program. RAW describes the product for vegetative growth and healthy leaf and stem development, making it relevant when that stage is the priority. At 2 ounces, the package is small and suited to targeted use rather than a large-area supply. The supplied details do not provide a mixing rate or application schedule.

Skip it if you need a larger quantity for broad coverage; The Grow Co 5 lb. Urea Fertilizer offers a five-pound pack.

Pick RAW Nitrogen if you want a small, water-soluble nitrogen powder to add to a vegetative-stage feeding program. Its stated focus is leaf and stem development; consider the limited 2-ounce quantity before planning repeated or large-scale use.

#4 · Best Organic

4. Burpee Organic Blood Meal

• Form: Granules
• Weight: 3 lb

Best for: OMRI-listed blood meal for vegetables.

Why it ranks #4: Its 3-pound blood meal is OMRI Listed for organic use and specifically suited to nitrogen-needing vegetables such as lettuce, kale, squash, and corn.

OMRI Listed status for organic use distinguishes Burpee Blood Meal for gardeners seeking an identified organic-gardening input. Its natural blood meal nitrogen source is aimed at crops including lettuce, kale, squash, corn, tomatoes, and other fruiting plants, with three pounds supplied.

The blood meal is described as a readily available natural nitrogen source, which supports its use as a starter fertilizer for fruiting plants and nitrogen-needing vegetables. OMRI Listed status makes the product relevant to buyers following organic gardening practices. Directions say to mix it with potting soil, offering a way to incorporate it into a planting medium rather than treating it as a liquid feed. Handling guidance calls for gloves and a mask and advises avoiding skin and eye contact.

Skip it if you want a smaller quantity for a small garden; Down To Earth Blood Meal 12-0-0 is listed in a 0.5-pound size.

Burpee fits organic gardeners feeding nitrogen-hungry vegetables or fruiting plants, especially when mixing fertilizer into potting soil. Its three-pound size suits more than a tiny application, and handling requires the listed protective precautions.

#5

5. True Organic Blood Meal

• Form: Granules
• Weight: 3 lb

Best for: Organic blood meal for leafy crops.

Why it ranks #5: This 3-pound granular blood meal targets heavy-feeding crops including corn, spinach, broccoli, and leafy greens, and is described as made with organic inputs.

Blood meal supplies the nitrogen focus in True Organic’s granular fertilizer, which is aimed at heavy-feeding crops such as corn, spinach, broccoli, and leafy greens. The three-pound bag is listed to cover 104 square feet, giving gardeners a stated area reference for planning use.

The blood meal ingredient and high-nitrogen purpose align with the product’s focus on rapid vegetative growth, making it relevant for leafy crops and other heavy feeders. Its granular form suits soil-based garden use, while the stated 104-square-foot coverage for the three-pound bag helps buyers estimate how much area one package can serve. True Organic also says its plant foods provide nutrients and increase microbial activity, supporting soil health. The listing advises that the product is not for consumption.

Skip it if you want an OMRI-listed product explicitly identified for organic gardening; Burpee Organic Blood Meal states that listing.

Choose True Organic Blood Meal for soil-based beds with nitrogen-hungry leafy crops, especially when the stated coverage area helps with garden planning. It is a granular blood meal, and it must not be consumed.

#6

6. Down To Earth Blood Meal

• Form: Powder

Best for: Small organic blood meal for containers.

Why it ranks #6: The organic 12-0-0 blood meal suits small gardens and containers, with listed soil application directions and a nitrogen-focused formula for early growth.

A 12-0-0 analysis in a compact 0.5-pound size makes Down To Earth Blood Meal a targeted organic nitrogen option for small gardens and containers. OMRI Listed status and a focus on heavy feeders such as corn, broccoli, and leafy greens clarify its intended use.

The 12-0-0 ratio and dried blood meal ingredient give buyers a defined nitrogen source for early growth and leafy development. Its OMRI Listed status supports use in organic gardening, while the small 0.5-pound quantity is specifically positioned for containers and small gardens. Application is by broadcasting or hand application, mixing into the soil surface or compost, and watering in well. Because it is not water soluble, this product belongs in soil-focused routines rather than liquid feeding setups.

Skip it if you need a water-soluble feed; Miracle-Gro Water Soluble All Purpose Plant Food is supplied as a soluble powder.

This is a fit for organic gardeners treating a small bed or container with a soil-applied nitrogen source. Its 12-0-0 analysis and compact quantity suit targeted use, but it will not fit a water-soluble feeding routine.

#7

7. TPS Nutrients Liquid Nitrogen

• Form: Liquid
• Weight: 8 oz

Best for: Liquid nitrogen for outdoor growers.

Why it ranks #7: This 8-ounce liquid is designed specifically for nitrogen support and green foliage, with listed suitability for lawns, gardens, crops, vegetables, and outdoor plants.

A liquid formula focused on nitrogen support makes TPS Nutrients a straightforward option for gardeners prioritizing foliage and steady growth. Its listed uses span vegetables, turf, and outdoor plants, so one bottle can serve several nitrogen-support needs across a yard or garden.

The liquid form gives this product a different handling format from granular and powdered options, while its nitrogen-focused purpose keeps the feeding goal clear: support green leaves and plant development. TPS Nutrients lists lawns, gardens, and crops among suitable uses, including vegetables and turf, which makes it relevant to mixed outdoor plantings. The 8-ounce bottle is a compact quantity for targeted use, though the supplied details do not specify a dilution rate or application schedule.

Skip it if you need a stated nitrogen percentage or a listed feeding schedule; neither is supplied for this liquid formula.

Choose this TPS Nutrients liquid if your priority is nitrogen support for foliage across vegetables, turf, or outdoor plants. It suits targeted garden use, but buyers seeking a stated nutrient ratio or application directions will need a product with those details listed.

#8

8. TPS Nutrients Vegetable Fertilizer

• Form: Liquid

Best for: Liquid feed for leafy vegetables.

Why it ranks #8: The 8-ounce liquid is aimed at vegetable plants, leafy greens, and herbs during leafy development, but its listing does not specify a nitrogen percentage.

A vegetable-focused, high-nitrogen liquid gives this TPS Nutrients formula a specific role during leafy growth. It is listed for leafy greens, herbs, and vegetable plants, helping gardeners direct nitrogen support toward garden crops whose early development and foliage are the priority.

The liquid form provides a distinct option for vegetable gardeners who prefer a non-granular product, and the high-nitrogen focus aligns with the listed goal of lush foliage and vegetative development. Its stated plant range—leafy greens, herbs, and vegetables—helps keep the choice centered on edible garden beds rather than a broad all-purpose claim. The bottle is 8 ounces, but the supplied information does not include a nutrient ratio, dilution instructions, or application timing.

Skip it if you want a stated 46-0-0 ratio; The Grow Co 5 lb. Urea Fertilizer lists that nitrogen analysis.

This suits vegetable growers seeking liquid nitrogen support for leafy greens, herbs, and other garden vegetables. Its crop-specific focus is useful for leafy growth, but the supplied listing omits a nutrient ratio and feeding directions for planning application.

#9

9. OULLYY Urea Fertilizer

• Form: Granules
• Weight: 14.4 oz

Best for: Measured urea for scheduled soil feeding.

Why it ranks #9: Its granules list a minimum 46.0% nitrogen content and directions for soil use, but the 0.9-pound package is smaller than other concentrated urea options.

A stated application rate of one-half pound per 100 square feet makes OULLYY’s 46% minimum-nitrogen urea unusually direct to plan. The dry commercial-grade granules are intended for soil incorporation and watering, with repeat application listed every seven weeks.

The 46% minimum nitrogen specification identifies a concentrated nitrogen source, while the directions give a concrete soil routine: apply one-half pound per 100 square feet into the top inch and water thoroughly. A seven-week repeat interval adds planning guidance that many listings omit. The 0.9-pound package is relatively small, so the stated rate helps buyers estimate its use across measured garden space. Its instructions focus on soil application rather than describing a water-soluble feeding program.

Skip it if you need a larger quantity for recurring lawn use; The Grow Co 5 lb. Urea Fertilizer comes in a five-pound pack.

OULLYY suits gardeners who prefer clear soil-application directions and need nitrogen for a measured area. Its 46% minimum nitrogen and seven-week schedule are specific, but the 0.9-pound quantity may require replenishment for broader coverage.

#10

10. Miracle-Gro All Purpose Plant Food

• Form: Powder
• Weight: 1.5 lb

Best for: All-purpose soluble feed for mixed plants.

Why it ranks #10: This water-soluble 24-8-16 formula feeds many indoor and outdoor plants, but it is an all-purpose food rather than a nitrogen-specific fertilizer.

A water-soluble all-purpose formula that feeds indoor and outdoor plants gives Miracle-Gro unusually broad listed coverage, from houseplants and roses to vegetables and trees. Its 24-8-16 NPK and instant-start description make it a practical choice for buyers seeking more than nitrogen alone.

The 24-8-16 NPK supplies a stated nutrient ratio beyond nitrogen, while the all-purpose label covers indoor, outdoor, and in-ground plants. That combination suits households tending different plant types without limiting feeding to leafy crops. The water-soluble powder is described as starting to work instantly, and directions include use with a Miracle-Gro Garden Feeder for outdoor coverage. The product is also stated not to burn plants when used as directed, and leftover powder can be kept dry and closed.

Skip it if you specifically want 46-0-0 nitrogen; The Grow Co 5 lb. Urea Fertilizer lists that higher nitrogen ratio.

Miracle-Gro fits households feeding a mix of indoor and outdoor plants who want an all-purpose 24-8-16 formula. It offers broader nutrient coverage than nitrogen-only choices, but is not the pick for buyers seeking a 46-0-0 ratio.
