Question 14
We have had a very dry fall this year. What kinds of problems should we expect next spring because of this weather?
When a plant goes into winter stressed from drought, its winter hardiness is often compromised. Perennials that we would expect to suffer higher than normal losses this winter include maiden grass (especially the variegated types), Joe pye weed, pink turtle head, Northern sea oats, golden Japanese forest grass, sweet woodruff and any perennial that is borderline in hardiness for this area. In addition to this, any perennials and evergreens that were planted late in the season and perhaps did not have sufficient time to establish themselves may be at risk as well. Certain species of trees and shrubs may also be hit hard, including Eastern redbud, honeylocust, fringetree, musclewood and summersweet clethra. It is particularly important to watch drought intolerant plants and newly established plants during prolonged dry periods.
Hopefully, all evergreens planted this fall have been kept well watered going into winter. That is a good practice in any year, but especially true when autumn weather is dry. If the soil has not yet begun to freeze, it is not too late to water your evergreens now. Set the hose on a slow trickle and let it run on the soil around each plant until the ground puddles up and won’t accept any more water. The length of time required for this will depend on the soil drainage in that area. Well drained soils will take longer to saturate than heavy clay soils.
If you mulched your plants well at any time this fall, that would also help them withstand the drier weather. Three to four inches of shredded hardwood bark mulch does wonders to help retain soil moisture and insulate the ground around plants all winter long. It’s not too late to mulch, even if the soil is beginning to freeze.
