This Month’s Tips
Happy New Year! It’s time to start planning…
- Plan to replace varieties of ornamental plants that are susceptible to disease with resistant cultivars in February.
- Take hardwood cuttings of deciduous ornamental shrubs and trees for propagation.
- Have your soil tested in your garden plot to determine its nutrient needs. Contact your local Extension office for a list of laboratories or view EM 8677 online.
- Begin planning this year’s vegetable garden. Check with local retail garden or nursery stores for seeds and seed catalogs.
Continue Monitoring for and Managing Pests and Diseases…
- Scout cherry trees for signs and symptoms of bacterial canker. Remove infected branches with a clean pruner or saw. Sterilize tools before each new cut. Burn or send to landfill before bloom. See Managing Diseases and Insects in Home Orchards (PDF – EC 631).
- Watch for field mice damage on lower trunks of trees and shrubs. Eliminate hiding places by removing weeds. Use traps and approved baits as necessary.
- Use dormant sprays of lime sulfur or copper fungicide on roses for general disease control, or plan to replace susceptible varieties with resistant cultivars in February.
- Mid-January: Spray peach trees with approved fungicides to combat peach leaf curl and shothole. Or plant curl-resistant cultivars such as Frost, Q1-8 or Creswell.
- Monitor landscape plants for problems. Don’t treat unless a problem is identified.
