Urea Fertilizer
Liquid urea fertilizer with a 15-0-0 NPK, sea kelp, and nitrogen from three sources — made to push fast, even green-up in lawns, leafy vegetables, shrubs, and foliage plants. Nitrate and ammoniacal nitrogen absorb within days while the 10% urea fraction feeds steadily, correcting the pale, washed-out green of nitrogen-starved plants without a surge-and-crash cycle.
How to Use Urea Fertilizer
| Method | Amount | How Often |
|---|---|---|
| Watering can | 2 tsp per gallon of feedwater | Spring & summer: once weekly |
| Watering can | Same dilution | Fall & winter: every 4–8 weeks |
| Hose end sprayer | Set to the 2 tsp setting | Same schedule as watering can |
| Leaf misting (optional) | 1 tsp per quart (32 oz) of water | Weekly |
Mix into your normal watering — no separate feeding routine needed.
What's Inside
The 15-0-0 analysis is nitrogen alone — 10% urea, 2.5% ammoniacal, and 2.5% nitrate nitrogen — for plants that need green growth and nothing else. Nitrate is the form roots absorb directly for a response within days, ammoniacal follows close behind, and the urea fraction converts in the soil over several weeks, so one feeding delivers a quick correction and a steady supply. With no phosphate or potash, it layers cleanly over any base fertilizer without pushing other nutrients out of balance.
Beyond NPK: sea kelp (Ascophyllum nodosum) for natural growth compounds. There are no added micronutrients — this is a deliberately focused formula. Nitrogen is the nutrient lawns and leafy plants exhaust first, and the shortfall shows as uniform yellowing that starts on the oldest, lowest leaves while new growth comes in small and slow.
Made For
Lawns, leafy vegetables like lettuce, spinach, and brassicas, sweet corn, hedges, shrubs, and shade trees — anywhere pale, nitrogen-hungry growth needs a push, in beds, rows, containers, or turf.
Problems It Solves
- Uniform yellowing that starts on the oldest, lowest leaves
- Pale, washed-out green across a lawn or leafy bed
- Slow regrowth after mowing, pruning, or a heavy harvest
- New leaves that come in small and stall before reaching size
FAQs
How often should I use urea fertilizer?
Add 2 tsp per gallon of feedwater and apply once weekly in spring and summer, dropping to every 4–8 weeks in fall and winter. A hose end sprayer set to the 2 tsp setting covers lawns and beds quickly. For an optional foliar boost, mist leaves weekly with 1 tsp per quart of water.
Why is my lawn or plant turning yellow?
Nitrogen deficiency shows as uniform yellowing that starts on the oldest, lowest leaves — or an overall pale green across a lawn — because the plant moves nitrogen out of old growth to feed new. That pattern responds to this formula within days. Yellowing between the veins on new leaves is usually iron or magnesium, which nitrogen won't fix.
Will urea burn my lawn or plants?
At 2 tsp per gallon, burn risk is low — the liquid dilution spreads nitrogen far more evenly than granular urea, which concentrates in prills. Apply to soil that isn't bone dry, keep to the directed rate, and hold off on drought-stressed turf until it's been watered.
What does 15-0-0 mean, and why no phosphorus or potassium?
The numbers are the N-P-K percentages: 15% nitrogen, no phosphate, no potash. Nitrogen is the nutrient plants use most and soils run out of first, while many soils already hold plenty of phosphorus. A nitrogen-only formula corrects the actual deficiency — alone or over a balanced base feed — without stacking nutrients you don't need.
Can I use it on vegetables?
Yes — leafy crops like lettuce, spinach, cabbage, and sweet corn respond strongly to nitrogen. For fruiting crops like tomatoes and peppers, use it early for leaf and stem growth, then ease off once flowering starts; heavy nitrogen late pushes leaves at the expense of fruit.
When will I see results?
Fast — the nitrate and ammoniacal fractions absorb within days, and most lawns and leafy plants visibly green up inside the first week. The 10% urea fraction keeps feeding for weeks after. Long-starved plants keep improving over a season of steady feeding; fully yellowed leaves won't re-green, but new growth comes in deep green.
