They developed fire blight last summer. We would like to try to save them. . . . What is the best way to attack?
It is very difficult to control and the plant will look very sorry, even when controls are being used but...
You can try treating the tree with a copper fungicide, starting as soon as temperatures reach about 55F on average in your area. Apply 1-2 times a week for the whole time it is blooming.
Any areas already infected will need to be pruned out. Prune at least 2-3 inches below the infected area. Clean the pruning tool with a 10% bleach solution in between EACH AND EVERY cut.
Even with this, you may not be successful but it is your best option. Good luck!
I have a beautiful Cleveland pear tree in my backyard. It is about 4 years old. The leaves have started turning a bronze tan color, starting from the outside of the leaf to the center, then the whole leaf is no longer green and starts falling. There is a younger Cleveland pear planted about 6 feet from it and it is ok. Any ideas? Could it be spider mites?
The tree is going dormant for the season. The smaller tree will follow suit very soon.
I purchased and planted a Cleveland pear tree. Today, the leaves on the tree are very droopy. I have been watering it every day. What do you think? It has been very warm and windy. Thanks.
