High Nitrogen Fertilizer for Plants

Anything grown for its foliage — vining houseplants, ferns, hedges and greens — and fast growers filling in a space. Flowering and fruiting plants want less once they start to bloom.

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.

Overall pale or yellow-green color starting on the older, lower leaves, and slow, small new growth. Nitrogen moves to new leaves first, so the old ones show the shortage.

Yes. This targets one shortfall; your regular feed supplies the nitrogen, phosphorus and potassium that drive growth. Use the two together.

Water it into moist soil at the labeled rate, or use it as a foliar spray in the morning or evening for a faster response on the leaves.

Pothos, philodendron, monstera, ferns and hedges are the most common cases, along with anything showing the deficiency signs above. It suits edible and ornamental plants alike.

Deficiency symptoms ease on new growth within two to three weeks; leaves that are already damaged will not recolor, but the next ones will come in healthy.
