Re: Crab Apple Tree Transformation

The most likely scenario is that the crabapples were grafted onto apple seedling rootstock that grew up through the crab and shaded it out so much that it didn't produce flower buds any more. The crabapple wouldn't just disappear and may have died out and was pruned off. Does the tree fork near the ...

Re: Pruning Maple Trees - Apple Tree Pollenation

Shari, It's ok to prune your maple tree now. No apple variety is sufficiently self-fruitful to be dependably productive when planted without a pollinizer. The pollinizer must be genetically compatible and bloom at the same time as your apple and planted close enough that you could expect bees to vis...

Re: Patio Peach Tree

Here is some descriptive information about 'Bonfire' peach, from The Brooks and Olmo Register of Fruit & Nut Varieties, 3rd Edition, ASHS Press, 1997, p. 411: "Bonfire- Dwarf red-leaved ornamental, from 1984 seed, selected in 1988, released in 1992...

Re: brown leaves

There are a couple fungal leafspots that could cause defoliation. These would typically be worse in seasons with long wetting periods and might be reduced with a registered protective fungicide. If it occurs again, I suggest taking a sample to your local extension office to send to the Virginia Tech...

Re: Patio Peach Tree

Commercial peach varieties are self-fertile and shouldn't need a pollinizing variety. I don't know specifically about this variety either. If you have room and want to plant another variety for other reasons, fine; but if you're limited on space, I believe you could try it without a pollinizer.

Re: Did I kill my Weeping Willow Tree?

Maybe your pruning after growth had started did set it back some, but I wouldn't expect this from pruning only dead limbs or killing of an otherwise healthy tree. I still suspect whatever killed those limbs as a possible cause that may have been advancing and, coincidentally with your pruning, went ...

Re: Did I kill my Weeping Willow Tree?

It doesn't sound optimistic that your tree isn't leafed-out yet like neighboring trees are. If it makes you feel any better, I don't think your removing dead limbs killed it. It may have already been near death (based on it having some dead large diameter limbs). There are some fungi that cause limb...

Re: Pruning weeping cherry trees

Debbie, Typically the Weeping Cherry cultivar is grafted about 5 ft. high on an upright understock or roostock. If you have upright sprouts clearly growing from the understock, they should be removed. It may be harder to judge whether upright shoots growing from near the graft union at the top of th...

Re: systemic insect and disease control

I am not aware of a product that is registered to be used as a soil drench for systemic control of foliar and fruit diseases and insects under fruit trees where fruit is going to to be eaten. Some of them might be registered for ornamentals such as crabapples but the label specfically warns that fru...

Re: Copper Sulfate

I don’t believe you will get enough systemic uptake of copper through the roots to control black knot and you might get serious tree injury by placing copper sulfate on the ground. A better management approach is to cut the knots out of the tree and get rid of them, and to protect new growth with ef...
