Azalea Fertilizer

Every 1–2 weeks during spring and summer while they're growing and setting buds, and every 4 weeks in fall and winter. Diluting into your regular watering (2 Tbs per gallon) keeps nutrition steady — azaleas have shallow, fine roots and respond better to consistent light feeding than to occasional heavy doses.

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.

That pattern usually means iron or magnesium isn't reaching the plant, and both are in the formula. But the underlying cause for azaleas is often soil pH: above about 6.0, these nutrients lock up no matter how much you feed. Keep soil in the 4.5–6.0 range and this nutrition will correct new growth within a few weeks.

Feed through spring and into summer to fuel the current bloom and the bud set for next year, which happens right after flowering. Ease off by late summer — late feeding pushes tender growth that won't harden before winter and can come at the expense of buds. Resume in early spring.

No — it's a fertilizer, not a soil acidifier. Azaleas need acidic soil (pH 4.5–6.0) to take up nutrients, so test your soil and use elemental sulfur or an acidifier to bring pH into range if needed. This formula supplies the nutrition; the pH work is separate and just as important.

No — at the directed dilution, the formula is designed for regular use. All-nitrate nitrogen and low salt concentration make burn very unlikely, which matters for azaleas' shallow roots. For newly planted shrubs still establishing, start at half strength for the first two feedings.

New growth typically comes in greener within the first few weeks of regular feeding, provided soil pH is in range. Bloom improvements show on the next flowering cycle — azaleas set their buds the season before, so consistent feeding through summer pays off in next spring's flowers.
