Lemon tree sick
« on: April 17, 2022, 10:30:07 PM »
Dear All,

I have asked this question in another forum, but submitting to this forum, too, to get any suggestions to save a lemon tree. I have a lemon tree outside my house, which seems to be sick. I need your help to save this tree if possible.

Here is a back-story regarding the tree: We live in Jupiter, FL, and bought a house 3-4 years ago. The lemon tree was there when we bought it, but I really did not have time to take care of anything regarding the gardening stuff as the HOA was doing all the trimming, etc. Last year or so, one of the neighbor said that the tree was giving lemons in the past, but not anymore. The tree looked sick at that time, too, but again I did not have time. 3 years ago, the palm tree 5-6 meters away from the lemon tree was struck by a lightening and I thought that might have been the reason. For the last one month, however, I am trying to understand what is going on with the tree, and if possible save it (not for the fruits but it seems that it tries to stay alive). I took several photos and uploaded them here so that anyone having some suggestions/ideas can help me save this poor tree.

Now regarding the tree and what I have done so far: I bought Citrus and Avocado Plant Food from Home Depot and applied it to the tree twice within the last month. Also, I bought Neem oil and applied it once last week. Finally, this weekend, I pressure washed all the stem and tree branches of the lemon tree, which you can see in the pictures. The fungus and any moss I could see got removed, thought there are still some deep spots resembling fungus on some of the branches (see pictures). Before pressure washing the tree, I pruned the tree, and removed all the dry branches. Then, I applied Citrus Plant Nutritional Spray I bought from Home Depot.

Initial observation: There are 3 lemons on the tree, as well as 4-5 small ones, which I think will fully grow if I can handle the tree properly. Also, there are probably 5-10 sprouts I could see on some of the branches. Furthermore, even though most of the leaves seem to be sick, the new ones are coming out normal. Finally, some of the branches seems to be damages badly (see Image # 1, 2, 7, 8, 17), which I thought is due to the lightning striking the palm tree 5-6 meters away from this lemon tree (I might be highly wrong!).

Any ideas and/or suggestions? I am planning on applying copper sulfate fungicide, but learned that I have to apply it in October.

Thanks in advance for your time and help.

Best regards,

Ilyas

Actually, the tree does not look all that bad.  The wound in the second picture looks like it has already healed itself.  From the pictures the white growth on the bark just looks to be some type of a lichen (which should not be a problem). I believe the tree condition is a result of not getting enough attention.  A citrus tree of that age should be fertilized 3 times per growing season.  The best to you and your tree.
