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.

At 1 tsp per quart, the 8 oz bottle makes about 48 watering cans of feed. For a typical shelf of 10–15 plants fed every 1–2 weeks in season, that's several months of feeding — and the 32 oz bottle four times that.

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.

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.

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.

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.

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.
