Frequently asked questions

What does 5-10-5 mean?

Five parts nitrogen, ten parts phosphorus and five parts potassium. The phosphorus emphasis supports root development and flowering, which is why this ratio is a classic for root crops, bulbs and bloomers.

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.

Why phosphorus for root vegetables?

Phosphorus drives root and bulb development. Too much nitrogen on carrots, beets or onions gives lush tops and small roots, so a lower-nitrogen, phosphorus-forward blend keeps the energy underground.

Which plants is this ratio for?

Carrots, beets, radishes, onions and garlic, 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.
