How to plant hostas
Wait for the right time to plant hostas.
Hostas aren't overly sensitive to cold, so you can plant them as soon as the ground is warm enough to work in the spring. Spring and late summer are the ideal times to plant hostas, because they are in active growth phases and will take root easily.
If you're going to plant hostas in late summer, do it at least six weeks before the first frost. Choose a location with the right amount of shade.
