Frequently asked questions

How often should I feed my lemon tree?

Every 1–2 weeks in spring and summer while the tree is actively growing and fruiting, then every 4 weeks in fall and 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.

Why are my lemon tree's leaves turning yellow?

Yellowing between green veins usually means magnesium or iron shortage, which citrus burns through quickly. Both are included here, along with the rest of the micronutrient package.

Will this burn my tree?

Not when used as directed. All of the nitrogen is nitrate nitrogen, which is gentler than ammonium-heavy fertilizers, so the burn risk is low at the labeled dilution.

Can I use it on indoor potted lemons and outdoor trees?

Yes. Use the same dilution for both — a watering can works for containers, and a hose-end sprayer covers larger in-ground trees.

When will I see results?

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