Frequently asked questions

What does 8-8-8 mean?

Equal parts nitrogen, phosphorus and potassium at a higher strength than our 4-4-4 and 7-7-7 blends, for established shrubs, big vegetables and plants that eat a lot over a season.

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 with it?

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 use this on young plants?

Yes at the labeled dilution, but seedlings and freshly rooted cuttings do better on a gentler formula such as Seedling Fertilizer until they are established.

Which plants is this ratio for?

Hydrangeas, boxwood, roses, tomatoes and squash, and similar plants that want this balance of nutrients.

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.
