Frequently asked questions

Which vegetables want high nitrogen?

Anything you grow for leaves — lettuce, spinach, kale, chard, cabbage and broccoli — plus corn. These crops build foliage fast and go pale and slow without it.

How long will one bottle last?

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.

How often should I feed vegetables?

Every 1–2 weeks in spring and summer while it is actively growing, then every 4 weeks in fall and winter. Mix it into your regular watering at the labeled dilution so feeding never becomes a separate chore.

Should I use it on tomatoes and peppers?

Only while they are young and leafy. Once they flower, switch to a balanced or bloom formula, or you will get big plants and little fruit.

Is it safe to use on food crops?

Yes. It supplies the same nutrients plants draw from soil, taken up through the roots. Rinse your harvest as you normally would.

Will this burn my plants?

Not when used as directed. The dilution is designed for regular feeding, and a liquid spreads evenly through the soil instead of sitting in a hot spot the way granules can. If you ever overdo it, flush with plain water.

When will I see results?

Greener leaves and stronger new growth usually show within two to four weeks of consistent feeding; flowering and fruiting benefits build over the season.
