Let’s get started.
Why Fertilizer Matters for Hostas
Hostas are heavy feeders, especially in spring and early summer. Since they’re grown for foliage rather than flowers, they need:
-
Nitrogen (N) → Promotes lush leaf growth
-
Phosphorus (P) → Strengthens roots
-
Potassium (K) → Enhances overall plant health
A balanced fertilizer (like 10-10-10) or slightly nitrogen-forward formula works best.

-

-

2. Liquid Fertilizer
-

When to Fertilize Hostas
