Frequently asked questions

Why are my dahlias all leaves and no flowers?

Usually too much nitrogen early on. Dahlias want a lighter nitrogen, higher potassium feed once they are established — this formula is built around that balance, so bloom production picks up.

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 dahlia?

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.

When should I start feeding dahlias?

Wait until plants are about a foot tall with a few sets of leaves, then feed every one to two weeks through the season. Stop about a month before your first frost.

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