Black spots on my apples
My apple tree is 6 years old and this is the first year it has produced fruit, but also the first year that the tree seems to be sick. The fruit has black spots and some of the leaves are yellow, browning on the tips or curling. The weather has been heavy rains with dry spells and very hot. We do not spray the tree and I did not fertilize it this year. Does anyone have an idea what is going on and how we can avoid it next year?
yes it is weird, the picture of the apple above (pink Lady apple) is like the spots on my apples, A master gardener , is the one who told me that is was called cedar apple rust.???? I don't know about ur silver maple trees.
well, your maples won't cause rust. It comes from cedars. However, there are varieties that are bred to be cedar apple rust resistant. It pays to double check that sort of thing when putting in a home orchard. We lost 2 Barlett pear trees to rust, so we replanted with Boscs and Sheckles. Both are resistant and at 15 years, producing heavily. Their certainly not purty but they taste marvelous.
I have 4 apple trees and just noticed 2 of them are doing the same thing, they are red/green very juicy, but same problem. The other two trees are fine! My apple trees and Roses, both same looking problem. Uhmmm!
@Laura, your roses probably have black spot. Another type of fungi, make sure you clean the bed throughly, bag and discard any fallen leaves. Black spot is an air borne fungus. It gets on your rose leaves and starts reproducing. When the infected leaves drop, they infect the soil with the fungal spores. When it rains, those spores get splashed back up on the roses, so it's a vicious circle. I use corn meal to help suppress the spores. It looks a bit odd, but I've found it to be very effective. And I live in VA the Black Spot Capitol, LOL Your apple tree issues are something different. Again, I would suggest contacting your local extension office and take samples to establish exactly what is wrong and what you can do to try and fix the problem.
@Laura I wonder if it has more to do with weather conditions than soil--we've never had this happen before to the apples. My tomatoes are also affected and think maybe spores get carried on the wind?
Weather this year is definitely a factor. Because of all the rain, fungi and mold have been a real issue all over the country. But your tomato problem is not coming from your apples. Two entirely different breeds of cat or mold there. This is where an extension agent who is normally a trained horticulturalist can help. You help pay for those services with your tax dollars, so don't hesitate to seek help with the problem.
@Catherine Smith --thank you, I hadn't realized they were "tax employees" now I won't feel like a pest.
The extension offices are branches of your land grant college. The program was started in the 40s I believe and is designed to help both farmers and home gardeners with problems, etc.
