I understand a copper sulfate solution is effective against fire blight. I have about one pound of copper sulfate crystals (blue). I don't need hundreds or thousands of gallons of the mix to treat my three pear trees. How much in grams or ounces should I use per gallon (or 5 gallon) to make the mix? I have an electronic scale that measures 0. 0 oz. I assume the answer you'll give me is by weight. . . . yes?
At its lowest rate, use approximately 9 grams of copper sulfate per gallon of water.
Eighteen Aristocrat pears are now infected with fire blight, and they are too big for me to trim each branch. Any other effective treatment?

We bought a house that has a mature (10-15 ft tall) Pear tree. I have no idea what care it has had in the past. It did produce lots of Pears last summer and is slightly shaded by a HUGE pecan tree. Also has visiting squirrels who usually beat us to the Pears. We would love to get the most out of our Pear Tree.
If it is mature and healthy, there is not much you need to do for it but a little clean up pruning now and then, a yearly application of balanced fertilizer and watering it in times of drought.
Clean up pruning will consist of removing dead or sickly branches and thinning out branches that are crossing one another.
For bigger fruits, you may want to consider thinning the fruit in the spring, but if it is producing what you would consider adequate size fruit, you do not have to do this.
My pear tree is so loaded it is bending the branches. Should I pick some of them off now?
What a treat to get this question! We always hear about a lack of fruit not too much. This is why I love my pear tree. It offers such an abundance. Yes, you can remove some fruit. It won't be edible, but your remaining fruit will grow larger.
We live in Germany. We have a Pear tree in the garden. Over the last few weeks, we have noticed the leaves have orange areas on them with what looks like either fungus growth or egg sacks on them. The growth has what I can only describe as four peaks, with white bases and black tips. Is there anything we can do or is our Pear tree doomed?
Could you send us a picture attached to this email That will help with identifying it.
A neighbor has several beautiful producing pear trees, but they all get infected with worms. Can you help?
Caterpillars and worms can typically be killed either by using Bt or neem oil, both of which are organic solutions. Here is more information: https://www.gardeningknowhow.com/plant-problems/pests/insects/prevent-caterpillars.htm
Pear tree was established 30 years ago. It now has brownish black spots on some, but not all, of the leaves. Also, some parts of the branches die off after fruit is established. Dont know what type, cross between William and Conference. The fruit is usually not ready till late September.
This could be caused from some type of fungus. Treat the tree with a fungicide and see of this helps.
