Disease resistant apples first line of defense for home orchardists By Katie Pratt LEXINGTON, Ky., (Oct. 23, 2013) – Apple trees are popular additions to home landscapes because of their fruit production. However, many home gardeners are not prepared for the onslaught of diseases that bombard the trees every year. To minimize risk of disease and reduce reliance on preventative fungicide applications, home gardeners may consider selecting disease resistant cultivars, said Nicole Ward Gauthier, extension plant pathologist with the University of Kentucky College of Agriculture, Food and Environment.

warm, rainy springs, trees can become severely damaged.” Selection of disease-resistant apple cultivars will provide some disease resistance in Kentucky and reduce numbers of required fungicide applications. Gauthier recommends Enterprise, Liberty, Priscilla and Winecrisp. A full list of disease-resistant cultivar recommendations for Kentucky is available on Gauthier’s blog at http://
To Do’s For November *Any trees or shrubs that you still have in containers should either be planted or hilled in. This simply means the pots can be buried in soil or mulch to protect the root balls from freezing. *You can plant most tree seeds now. The cold winter weather will satisfy their dormancy requirements and they will sprout next spring. If they don’t have an extremely thick seed coat such as Kentucky Coffee Tree. Trees seeds such as these should be filed down a little to break the seed coat. This will allow the seed to uptake water and germinate. *If you see any bagworms hanging on your shrubs go ahead and pick them off and step on them. Each of these bags could contain up to 1000 eggs ready to hatch and munch on your landscape next spring.
*After leaf drop spray peach, nectarine, and plum trees with Ferbam, Bordeaux mixture, or daconil 2787 to control peach leaf curl and plum pockets disease next spring. *Black knot galls on branches of plum and cherries should be pruned out 4-8 inches below the gall. Destroy of by burning. *Remove all grass and weeds from around your fruit trees to discourage nesting of mice and voles. They will gnaw the bark in the winter and could girdle the tree. Wrapping the trunk with tree guard will help discourage rodent feeding.
Ornamentals

mound soil or mulch over the bud union of your roses to keep them from freezing out. This isn’t necessary if you have roses on their own root meaning they weren’t grafted. *Apply 3 inches of mulch to your perennial bed after the ground freezes to prevent them form heaving out of the ground when it freezes and thaws. *Plant any spring flowering hardy bulbs now. *All tender bulbs such as cannas, calla, elephant ear, dahlia, etc. should be dug and brought indoors for the winter. These are freeze sensitive and rot prone during the winter. You should store them in a cool dark place above 32 degrees. *If you have had trouble with deer digging an eating your hardy bulbs plant alliums, autumn crocus, grape hyacinth, hyacinth, daffodils, and galanthus. They don’t like these as much and are less likely to feed on them. In fact autumn crocus is poisonous.
Vegetables *Cool season vegetables will be good in the garden until the temperatures get down into the low twenties. *Extend harvest of cool season vegetables such as broccoli, cabbage, cauliflower, radish, turnip, beet, lettuce, spinach, etc. by covering them with remay fabric or tobacco canvas. *Cut back asparagus tops after they have frozen back. Apply a fresh layer of mulch after the ground has frozen. *It’s not too late to plant a cover crop of winter wheat or rye.

While many of the recommended cultivars are disease resistant, they have little resistance to insects. Home gardeners wanting to minimize insecticide applications may want to bag individual fruit when they are roughly an inch in diameter. Ric Bessin, UK extension entomologist, authored a fact sheet on how to bag fruit. ENTFACT 218: Bagging Apples: Alternative Pest Management for Hobbyists is available online at http://www2.ca.uky.edu/entomology/ entfacts/ef218.asp.

A Note From Dennis Well the growing season has officially ended with the hard freeze recently but I do have a few things left in the garden such as dried beans and turnips that I can harvest. I will most definitely harvest the beans but the turnips will probably just be a cover crop. I like most every vegetable but I just don’t or can’t eat turnips, the greens are fine but cooked turnips taste like dirt to me. It’s Halloween week and the kids are excited about dressing up, Gabby is going as a vampire and Tori is going as a cat. It should be interesting to say the least! Last week they both won the book character contests in their rooms for best costumes, thanks to their Mother of course! Gabby was Pinkalicious and Tori was Angelina Ballerina...you should check the books out for some great reading for your daughters and grand daughters. The Wheelbarrow Series is slowly coming to an end with just three classes left: amaryllis, landscape plants for holiday decoration, and wreath making. There will be changes to the 2014 Wheelbarrow Series with regards to number of classes and times etc. so be on the look out! If you have any topics you would like to see covered give me a call.
