Is my apple tree diseased? Please advise!
5 years ago
Can anyone tell me if my newly planted Fuji apple tree is diseased? I’ve done a bit of research, and my best guess would be apple scab (?) based on the brown spots on the leaves. There are also these light spots going up the trunk (see pics). I’ve never grown an apple tree before so I can’t tell if any of this is an actual problem or not. It’s possible I’m overreacting because the tree is really important to me. I planted it as a memorial for my dog Hercules who died last week. Fuji apples were his all time favorite snack. Anyway, I’m open to all and any advice! Zone 9a. Thank you.

Comments (8)Here in middle Tennessee, I would categorize it as "highly" susceptible. It does fine when sprayed, but left untreated the leaves eventually become nearly completely covered. I'd say about the same as Gold Rush, which I'd also consider as highly susceptible - at least in my climate. I have another variety called "Gold Star", that even when treated still got a moderate amount of CAR. Would hate to see what it looks like untreated....See MoreCitrus Trees and Apple Tree Diseased??
Comments (16)Okay I got the response from the local extension office and here is the diagnosis: "The pictures of actual fruit are showing symptoms of bird damage. Grackles and Starlings will visit the fruit when about the size of a dime and peck, scratch and scar the fruit to cover themselves with citrus oil which serves as a mite repellent. Unless you cover the tree at that time of the year with a bird netting, there is not much you can do. See: http://www.plantanswers.com/citrus_damaged.htm . The brown spots on your apple leaves are caused by a fungus of some sort. Most any fruit tree can be sprayed with Captan fungicide solution. Follow the label directions. Also, even some of the healthy leaves are yellowing, which indicates nutrient deficiency. Several things can cause the symptoms: 1) lack of enough nutrients in the soil; or 2) a root system that is not pulling in the available nutrients because of drought stress, too much water, and competition from weeds/turf grass. Even the fungal spots on the leaves may be worsened by a nutrient-stress issue. First, you may want to check the soil pH and nutrient level by submitting a soil test. Second, remove all weeds/turf grass 18" to 24" out from the main trunk and apply a light layer of an organic mulch such as leaves, dried grass clipping (from grass that hasn�t been sprayed with a broad-leaf weed killer). Third, monitor soil moisture to make sure that the trees are not too dry, nor too wet. Also, dried leaves on a living stem is a good indication of soil/moisture stress. Dried/dead leaves on a dead stem may indicate a canker or gall or wood boring beetle issue. Call my office at 281-342-3034, and ask for ext. 7029 for a soil test bag and form. -Vincent Mannino" The link to the pictures still works if you want a visual summary of my issues.

Comments (3)Carol if that picture was not taken during growing season the look of the leaf doesn't matter. When the leaves are about to fall off they get all sorts of funny looks because they are starting to decay already. I don't think its scab, the spots are green so they are the healthy bit and scab is the opposite....See MoreRelated Professionals
