Nitrogen Fertilizer
Liquid nitrogen fertilizer that supports greener foliage and fuels leafy growth. Water soluble nitrogen for lawns, leafy crops, and foliage plants.
Use it as a targeted supplement alongside your normal feeding program, following the label rate so you can add the specific nutrition your plants need without complicating the routine.

Nitrogen Fertilizer with a straight 15-0-0 analysis from three nitrogen sources — no phosphorus or potassium, just concentrated nitrogen to green up plants and push lush leafy growth. The three-source blend of nitrate, ammoniacal, and urea nitrogen feeds both fast and steadily, correcting the pale, stalled growth of nitrogen-hungry plants without the surge-and-crash of a single-source feed.
How to Use Nitrogen Fertilizer
| Method | Amount | How Often |
|---|---|---|
| Watering can | 2 tsp per gallon of water | Spring & Summer: apply once weekly |
| Watering can | Same dilution | Fall & Winter: every 4-8 weeks |
| Hose-end sprayer | Set to 2 tsp setting | Spring & Summer: apply once weekly |
| Leaf misting (optional) | 1 tsp per quart (32 oz) of water, spray on leaves | apply weekly |
Use as a nitrogen supplement alongside your regular feeding, not in place of it — with no phosphorus or potassium, this targets green growth, not flowering or fruiting.
What's Inside
The 15-0-0 analysis is nitrogen alone — no phosphorus or potassium — for plants that need green growth and nothing else. What makes it work steadily is the three nitrogen sources: 2.5% nitrate nitrogen, which roots absorb directly for a response within days; 2.5% ammoniacal nitrogen, which converts in the soil over a week or two; and 10% urea nitrogen, which feeds gradually as it breaks down. Together they deliver both a quick correction and a long, even supply, so plants don't spike and fade.
Beyond NPK: sea kelp (Ascophyllum nodosum) for natural growth compounds that aid nutrient uptake. This is a deliberately focused nitrogen supplement, not a complete fertilizer — there's no added phosphorus, potassium, or micronutrient package. Use it to correct nitrogen deficiency, the uniform yellowing that starts on the oldest, lowest leaves, or to push leafy growth on lawns, leafy greens, and foliage plants, alongside a balanced feed that covers everything else.
Made For
Built as a nitrogen supplement for plants that need a green-up — lawns, leafy greens, corn, and foliage plants — and for correcting nitrogen deficiency, used alongside a complete fertilizer that supplies phosphorus and potassium.
Problems It Solves
- Uniform yellowing that starts on the oldest, lowest leaves
- Pale, washed-out green across a lawn or leafy crop
- Slow leafy growth on nitrogen-hungry plants
- New growth that comes in weak and light
FAQs
How often should I use nitrogen fertilizer?
In spring and summer, apply once weekly at 2 tsp per gallon, using a watering can or a hose-end sprayer on the 2 tsp setting. In fall and winter, cut back to every 4-8 weeks. Because this is straight nitrogen with no phosphorus or potassium, use it as a supplement alongside your regular complete feed, not as the only fertilizer — and don't overapply, since excess nitrogen causes problems of its own.
Why is my plant or lawn turning pale or yellow?
Uniform yellowing or pale green that starts on the oldest, lowest leaves is the classic sign of nitrogen deficiency, which this product corrects. But not all yellowing is nitrogen — yellowing between the veins points to magnesium or iron, and whole-plant yellowing with wilting often means overwatering. Nitrogen fixes the pale, hungry look of a plant that's simply short on it; if the pattern is different, the cause is likely different too.
Will nitrogen fertilizer burn my lawn or plants?
Any concentrated nitrogen can burn if overapplied, which is why the three-source blend here matters — the urea and ammoniacal fractions release more slowly than pure nitrate, giving a steadier, lower-burn feed. Still, stick to the labeled rate, water it in, and avoid applying to drought-stressed or bone-dry plants. More nitrogen doesn't mean faster growth past a point; it just raises the burn risk and pushes soft, weak growth.
What does 15-0-0 mean, and why no phosphorus or potassium?
The three numbers are the percentages of nitrogen, phosphorus, and potassium. 15-0-0 means 15% nitrogen and none of the other two — a targeted nitrogen supplement rather than a complete fertilizer. It's meant for situations where a plant needs nitrogen specifically: correcting a deficiency, greening a lawn, or feeding leafy growth. Pair it with a balanced fertilizer that supplies phosphorus and potassium so the plant's full needs are covered.
When will I see results?
The nitrate portion works within days, so pale plants and lawns often green up noticeably within a week, while the ammoniacal and urea fractions extend the feeding over the following weeks. Existing severely yellowed leaves may not fully recover, but new growth comes in greener and stronger. For lawns, the green-up is usually the fastest and most visible response.
