Frigid Temps and Falling Leaves
Recent frigid mornings remind us that the first average frost date is approaching. For most of Tidewater, that date is November 15. Not to say that it will frost that day, but the chances of a killing frost begin to rise after that and for gardeners, it marks a turning point in the year. Unless, of course, you live in Tidewater, where one frost does not a winter make. Recent winters have shown that temperatures can change quickly and without much warning. Be prepared to protect plants from frost or freezing temperatures by having the supplies you need on hand beginning this month. A few points to remember:

  • Most of Tidewater is in Zone 8a (more about zones here) which means that a plant hardy to our zone can survive average low temperatures of 10 – 15F.
  • When frost arrives, hardy perennials turn yellow to black and die back to the ground, but the root systems should be fine.
  • Tender plants – those that are hardy in Zones 9-11 – should be protected from frost. Depending on which zone these plants are in, they can survive low temperatures from 20F (Zone 9) to 45F (Zone 11).
  • Plants in containers need special attention, even if they are hardy in our zone. Because the roots are above ground they are not as protected as those that are planted in beds. Move them indoors when temperatures drop to near or below freezing – any place that stays above freezing will do.
  • If you are bringing plants into your home for winter, be sure to provide enough humidity around the plant. Set the plant on a tray filled with pebbles and water (be sure the bottom of the pot is not in the water) or mist the plant with a spray bottle.
  • Be on the lookout for insect pests on overwintered plants. Mealy bug and spider mites are common on plants brought indoors. For more information on dealing with these pests, please refer to the Pest Management Guide.

There are other measures you can take to help protect your outdoor plants during winter. If you’ve planted “borderline hardy” plants in your garden, mulch them heavily to give some added protection around the roots. When temperatures drop, cover them with old sheets or burlap. Make sure the edges of the covering are touching the ground and use something heavy to keep them in place. This will help trap heat from the ground around the plant and provide a few degrees of extra warmth.

Fallen leaves or pine needles can be used as mulch and are readily available this time of year. If you have more leaves than you need for mulching, consider composting them to use as a soil amendment next year. More information on turning leaves, grass clippings, and kitchen waste into compost can be found here.
November's Garden To-Do List:
  • rake leaves as they fall and add to beds as mulch or compost
  • continue providing clean water sources for birds and insects
  • plant spring blooming bulbs
  • add mulch to protect perennials from winter temperatures
  • prepare pots for winter by emptying and storing upside down
  • divide perennials that have outgrown their space and replant in another area or share with friends
  • consider drying or freezing tender herbs before frosts arrive
  • plant trees & perennials so that roots are established before the heat of next summer
  • remove yellow, diseased, or dead leaves from roses and surrounding area to help cut down on disease next year
  • if needed, prune certain shrubs like abelia, beauty berry, and gardenia - see the Pruning Calendar for a complete list
