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!
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.
Don't forget to replace the mulch around the hostas keeping the mulch away from 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. I prefer liquid fertilizer for my potted hostas. It's just a personal preference.
A boost of nitrogen through the season will keep those beautiful leaves looking their best.
