Garden Checklist for the week of December 12, 2019
Walk through the garden and make notes for spring and summer changes and additions. Enjoy the quiet of the winter garden. Feed the birds.
• Apply pre-emergent herbicide to lawns and beds later this month.
• Deep-water trees and native plants if rainfall has been light.
• This is the time to work on dormant, deciduous plants —shrubs, vines, grapes and roses, plus fruit and nut trees.
• Crepe myrtles and redbuds may be pruned now.
• Cut back and divide perennials.
• No fertilization is recommended this month.
• When you do fertilize, always read labels carefully before application. Consult a plant expert at a nursery or a Master Gardener if you have questions.
• This is the beginning of bare-root planting season. It is difficult to visualize the potential of bare-root plants, but they usually come with pictures to give you an idea.
