October Tips*
q If your lawn is a summer grass (such as Bermuda, Centipede, St. Augustine or Zoysia) you might consider overseeding with annual Ryegrass which will stay green all winter. Fertilize with an organic 15-15-15 formula to help the Ryegrass along.
q Continue planting cool-season grasses through mid-October.
q Order spring-flowering bulbs for fall planting now. Do not plant bulbs until November.
q Plant fall annuals now to change color schemes and to replace flagging summer annuals.
q Do not prune trees or shrubs this month. Pruning now can remove many of next year's flower buds as well as force tender new growth which may be killed by a hard frost.
q Do not fertilize trees or shrubs this month. Fertilizing can also force tender new growth which may be killed by a hard frost.
q You may begin planting trees and shrubs this month, although better to wait until next month when plants are fully dormant.
q Continue to monitor soil moisture around newly planted shrubs & trees. If we receive less than 1" of rain per week, provide supplemental water. Consider attaching a rain barrel to your downspout to collect rainwater for later watering of plants when rain is scarce.
q Continue to deadhead roses, cutting back to a bud above a five-leaflet set.
q Begin cutting back perennials as the foliage dies, unless they offer winter interest (such as Sedum 'Autumn Joy'.) Remove all plant material to prevent spread of pests and diseases.
