It's no surprise that hostas continue to be one of the most popular perennial plants in a variety of gardens. Their beauty, toughness, and ease of care make them well suited for a shady or partly sunny area, and they will quickly become even a new gardener's favorite plant!
But how can you keep those beautiful hostas thriving year after year?
Although hostas are tough plants and they may not need fertilizer if grown in very rich, well-draining soil, following a yearly fertilization schedule will ensure that you keep your hostas remaining healthy and looking their best.
There are as many ways to fertilize your perennials as there are gardeners. Here's the schedule that we follow for our hostas at Sunset Hosta Farm.com.
As the hostas emerge in the Spring, rake back leaves and mulch and apply a 10-10-10 balanced fertilizer (preferably granular slow-release) around the emerging clumps. Replace the mulch around the hosta but not up to the emerging clumps.
Hostas In Pots
If you've stored your potted hostas in an unheated garage or shed over the winter, slowly begin to acclimate the hostas to the outside temperatures as it warms.
Fertilize pot-grown hostas with a diluted fertilizer (at 25% strength) every few weeks stopping in early summer.
Hostas generally will not need fertilizer during the summer if adequately fertilized in the spring. However, if a second fertilizing seems to be necessary, do it in early summer.
Give the hostas a second (and last) feeding of a balanced 10-10-10 fertilizer. If the hosta leaves aren't looking their best, a fertilizer with a little more nitrogen can be used at this time.
Be sure to stop all fertilizers two months before your expected first frost date to allow the hostas to slowly settle into their winter dormancy.
