Hi, the leaves on my apple, pear and cherry trees are being consumed by flying black insects. I'm trying to identify what type of bugs these are so that I can determine how to treat the trees to get rid of them. The trees are still pretty small... 3 years old, 5-6 ft. I appreciate any advice you can give to help me save these trees. Thanks! - John
WOW!!! Those are hornets, and will likely send you to the hospital. They do not eat plants, and are feasting on whatever is eating those trees. I would recommend having a professional removing those, since they are known for killing people in swarms such as this. They will also help you to get rid of what is killing your trees, but this should be priority. This is a very dangerous situation.
Hello, Love the site. Last November I set three apple trees in our garden. I estimate they are about 4 years old. Apart from looking at them I hope to produce lots of apples in the years ahead. Two are sweet apple tres and one is a cooking apple tree. However, I am a novice when it comes to pruning. Can you please take a look at the pictures I have attached and please advise where is the best place to prune. Should I cut to make a dominant branch? Or do they look good enough to you. In one of the trees the leaves seem to be at the top of the branches and I feel I should be pruning it so it isn't so stalky? I look forward to your advice. thanks, Pat.

Last year my apple tree produce a good crop but without seeds pips this year a good crop with seeds could you explain please
Is there a new apple tree in the area? Sometimes when the correct pollinator to your apples get planted, they can cross pollinate, and you will have seeds.
Sometimes, this can be a naturally occurring issue. I don't see it as much of a concern, but it may be possible that it just didn't get pollinated last year. If someone happened to plant a compatible tree within the flying distance of the tree, then it can get pollinated like this.
Is it safe to add Black Rot infected apples to the compost heap. Heap hygiene would suggest it would be unsafe.
I would also suggest it to be unsafe. You should never add any infected material to the compost pile. You can try adding wettable sulfur the the are in an attempt to kill off the infection in the soil.
living in Wis, I want to plant grass under some apple trees. pretty shading under trees, what grass would you plant under those trees.
Kentucky bluegrass, and perennial ryegrass are you best choices here.Rye grass will not spread as fast, however.
Trees are 4-6yrs old, were pruned for the 1st time this fall. What should I do? Thanks for your time and assistance. Kim
This seems to be a case of what is called frost crack. This article will explain: https://www.gardeningknowhow.com/ornamental/trees/tgen/cracking-tree-trunks.htm
where can I find lime-sulphur spray?? I live in Clatskanie Oregon.
Lime sulfur, calcium polysulfide, is so caustic that EPA now requires a pesticide license to use it. Extensive personal protective gear is necessary. I doubt that it is available to home gardeners but is still available for farm/crop usage. Here is one caution label, to give you an idea of the hazards to users. http://cru66.cahe.wsu.edu/~picol/pdf/WA/30892.pdf
