The compost will break down, improving the soil structure and fertility.
Plus, you’ll perk up your perennials.
If you don’t have access to compost, you could use shredded leaves or well-rotted manure.
You also can use a packaged fertilizer, such as 10-10-10 or fish emulsion.
To successfully incorporate fertilizer around existing perennials, do the following:
Check your timing.
Pull away any mulch.
Add the fertilizer or compost.
When using fertilizer, carefully measure the recommended amount.
Avoid overdoing it, as too much can be harmful.
Sprinkle fertilizer evenly on the ground around the plants.
Avoid getting fertilizer on plant leaves or stems, because it can burn them.
Lightly work the fertilizer into the soil.
Replace the mulch.
Soak the soil thoroughly.
Gently wash off any fertilizer that may have gotten onto the plants.
