Frequently asked questions

Why are my fern's fronds turning brown?

Dry air and dry soil are the usual causes, followed by too-strong fertilizer. Ferns like consistently moist soil, humidity, and a gentle feed at the labeled rate — never more.

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 boston fern?

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.

Can I mist this on the fronds?

Yes, a light misting at half the watering strength adds humidity and a little foliar feed at once. Do it in the morning so fronds dry by evening.

Which boston ferns can I use it on?

All of them — boston fern, kimberly queen fern, maidenhair fern, bird's nest fern and staghorn fern, and the rest. The formula is built for the whole group, so one bottle covers a mixed collection.

Will this burn my plant?

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?

New growth usually looks greener and fuller within two to four weeks of consistent feeding; older leaves take longer to change.
