During
a prolonged warm spell in January, I noticed that some of my perennials
had sprouted. What should I do? Will they be killed by the next hard
freeze?
Answer:
Though you may
not be able to save these early sprouts from freeze damage, you
can help protect the crown of the plant by covering it with a light
mulch such as straw or finely shredded bark. If the plants are hardy
in your region, they should resume growth once the weather warms.
