The Hosta Gardening Calendar

Fall (Maturation of seeds and onset of dormancy) late September-October-November
As the days shorten toward winter, hostas prepare for dormancy. As the chloroplasts begin to break down and the bright yellows of hidden pigments, caroteins and xanthrophylls, begin to appear, green hosta leaves turn to gold. The leaves then begin to dry and petioles weaken and droop. The dry air helps the ripe seed pods to spring open, allowing the seeds to fly away on the wind. Usually it takes two or three hard freezes to knock the shriveled hosta foliage to the ground, while the flower scapes will persist intact through the first snows of winter.
Labeling: Make sure every hosta has a label before it becomes unidentifiable. The ones in pots probably need a new label as well. They tend to fade over the winter.
Light: The leaves are falling and the light continues to fade never the less. The days shorten inducing dormancy.
Nutrients: None needed.
Pests: Only the voles are a problem now. Begin to bait and trap again.
Protection: Remove tree leaves from the garden to discourage the voles from moving in. I use a leaf blower and not a rake. Finish cutting flower scapes. Apply mulch to your new plantings and touch up as needed.
Propagation: Hurry up! It is almost too late.
Water: Make sure your hostas are full of water the night before the first hard freeze. Usually rain comes with the first real cold front of the season, but if the fall has been dry you might need to soak the garden one more time before you lock the pump house for the winter.
Fun! Collect a few seeds and
