- 1). Scatter the 10-10-10 granular fertilizer, at the rate suggested on the package, on the soil around the hosta plants. Do not allow the fertilizer to get on the foliage.
- 2). Use a hand cultivator to lightly scratch the granules into the top inch of soil. Be careful not to cut into the plant’s roots.
- 3). Water as you usually do. This helps activate the fertilizer and get it down to the roots.
- 4). Reapply the fertilizer, at the same rate and in the same manner, once in early summer and again in late summer, but no later than August.
