Re: advise on mulching apple trees

There can be a concern with voles under mulch. A layer that is thick enough to keep the weeds down is also thick enough to hide the voles. I would keep it at least two feet away from the trunk where they would do the most serious damage.

Re: removing suckers that have regrown after late winter pru

It is ok to remove the rapid-growing "suckers" (also called water sprouts) from the trunk and large scaffold limbs in early summer. Actually, some growers just strip off the tender green shoots by hand rather than cut them at the base with pruners. My only caution is to do this shoot removal when th...

Re: Apple pear/ Asian pear tree

You should be able to grow Asian pears in your area. However, they are generally susceptible to fire blight, comparable to the most susceptible apples. It is recommended that you plant two or more varieties in close proximity for pollination purposes. Here is the projected ripening of Asian pear var...

Re: Need help to identify tree and damage

Good. It sounds like the main problem on the damaged tree is sapsucker injury. I haven't seen that kill a crabapple, and usually those wounds will heal over. Again, if there are any dead limbs in the tree, those might have been killed by fire blight, and they should be removed back to healthy wood d...

Re: Need help to identify tree and damage

The pictures are pretty small to be certain, but I believe this is a crabapple. If you cross-section a fruit and you see a 5-pointed star in the cross-sectional view, that confirms that it is a crabapple or apple. The trunk damage is most likely from yellow-bellied sapsucker. A crabapple might be he...

Re: pyracanthas attacked by white, fuzzy stuff

White fuzzy stuff and brownish/reddish liquid when you squeeze them?- sounds like you have wooly apple aphids. Wooly aphids are often suppressed naturally by parasites, but they can become a problem if an insecticide such as a pyrethrin is used to control something else and kills off the parasites. ...

Re: Golden Delicious Spots

The prominent orange lesions in the top picture are one of the apple rust diseases, probably cedar-apple rust, which requires the alternate host eastern red cedar to complete its disease cycle. The most effective product for apple rust control available to home gardeners is Spectracide Immunox Multi...

Re: Lacebugs

We had a perennial problem with lace bugs on our azaleas until I tried Bayer Advanced Tree & Shrub Insect Control specifically to test it as a soil drench. Applied as a soil drench with the rate carefully calculated for shrub size, a single application gave excellent control for more than a year. It...

Re: Pyracantha Berries turn Black

Dell, The problem with the blackened fruit is probably due to infection by the scab fungus. I would say the initial leaf and early fruit symptom color is more olive green or brown than black but it may be black by now. Scab is a wet weather fungus and its suppression requires a protectant fungicide ...

Re: Quince rust on apple trees

Joe, All the quince rust infection on apple fruits (and also hawthorn leaves and fruit) is caused by spores that came from cankers on the eastern red cedar. Quince rust infects apple blossoms during wetting periods from pink bud stage to petal fall. Little fruits become resistant soon after they beg...
