I’ve had it in the ground for a few years, its shown very poor growth so far. Puts out a few flowers every year, but no fruit. Most of the leaves seem to succumb to something by summertime. Even if I spray for insects, I get die back like this happening:
I think it has fireblight, and I would replace it. Unless you’re particularly fond of GS you can find recommendations for fireblight resistant varieties here and elsewhere.
I agree with marknmt, looks like FB. I get rid of FB trees ASAP. I do not want that FB to spread throughout the rest of my orchard. Better safe than sorry. I tried cutting FB out of some trees over the years but it seemed to not help to stop it.
Thanks a lot guys. That’s too bad. Granny Smith is my favorite apple, and you can’t buy it here in Japan. This is my only Apple tree.
My area is very hot and humid in the summer. I’m guessing apples don’t like that, which is why I don’t see people growing apples in my area. Is this tree a lost cause and I should cut it down? It looks pretty miserable, lol,
Can you buy another GS apple tree? If so I would just replace that tree and start over. If you have the room for two trees I would plant another variety of apple to increase the production of the GS apples. Such as a Golden delicious apple variety. You could also get a crabapple to plant to cross pollinate the GS. You just have to make sure the crabapple is blooming at the same time as the GS apple such as a crabapple called “Snowdrift”. Just a suggestion. Good luck.
I don’t know about growing apples in your area, but yes, I would remove the tree and start afresh.
