What Happens in Winter?

 

Winter is almost officially here – December 21 is the first day – but most of us consider that once December arrives ... it's winter. We’ve had some balmy weather this past week, but remember that we had snow this week just five years ago in metro Atlanta. December temperatures can vary but the change in the number of light hours is the signal to plants that it’s time to do something different.

Winter is a time of rest for many plants; woody deciduous plants discard their leaves and stop the processes that support leafy growth. Note: the fallen leaves still support the plants because they return nutrients to the soil as they break down. Fallen leaves also support many insects; the leave the leaves message is an important one. 

Perennial herbaceous plants (these are not woody) will die completely to the ground although some will have a rosette of winter leaves (cardinal flower (Lobelia) and beardtongue (Penstemon) are two common ones). [Also a time for rest for us unless you want to tackle winter weeds.]

Winter is also a time for growth in Georgia. In most of Georgia the ground doesn’t freeze so plant roots can grow and we also have good rainfall. Experienced gardeners know that trees and shrubs do well when planted in November and even December in Georgia. Georgia’s Arbor Day is in February (still winter!) and it is a great time to plant. Use the time to grow your garden with new (or replacement) trees and shrubs.

Without the distraction of so much foliage, it’s a great time to appreciate our evergreen plants, or the structure (silhouettes) of our majestic trees. I also enjoy getting out for winter hikes. The waterfalls can be especially full and beautiful thanks to our winter rains.

Enjoy your winter and know that the plants are getting ready for spring.
