Frequently asked questions

When should I feed grapevines?

Early spring at bud break and again just after flowering. Stop feeding by midsummer so the vine ripens its fruit and hardens its wood before winter.

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 my grapevine?

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.

Will fertilizer help my grapes get sweeter?

Potassium supports sugar development and ripening, and this formula supplies it. Sun exposure on the fruit and not overloading the vine with clusters matter just as much.

Can I use it on potted and in-ground plants?

Yes. Use the same dilution for both — a watering can for containers and small beds, a hose-end sprayer set to the labeled rate for larger in-ground plants.

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 show within a few weeks; the flowering and fruiting benefits build over the season and are most visible at the next harvest.
