    Hello all,
    We have two young citrus trees in the backyard (clementine and orange) and both have the same problem.
    Newly grown leaves falling off the trees and branches become black :(

    Here are some photos -

    The most common cause of stress or death of plants is overwatering. For citrus trees it can also be caused by cold roots. Are the trees in the ground or in pots?

    They are in the ground.

    Hi Alex and welcome to GarenStew. :-D

    I found this website that may point you in the right direction. I hope you can identify what is wrong with your young trees and that they can be saved.

    I also think it is a case of cold feet (roots) (Pardon the pun) and possibly frost in your area.
    Most citrus trees prefer mild winters and hot summers.
    Since your trees are still young I would suggest that you prune out the diseased parts and treat the wound with some steriseal (or similar product to seal the cut) to keep out harmful bacteria, etc. Protect your trees against frost. Do water your trees on a weekly basis during the first year and only twice a month after that. In the first year it is important to not allow the trees to dry out totally.
    As soon as you see the first blooms on your trees you should feed them with a half a cup of 2:3:2 fertilizer and a compost mulch.
    I hope you can still save your trees. :stew2:

    Thank you very much for your suggestions!
    I think it's not caused by cold roots, we have warm climate here in Cyprus.
    The lowest winter night temperature is about +5 Celsius (41 Fahrenheit) and there is no frost at all.

    is it possible some tiny bugs stressing ur trees?
    we here in romania can only grow them in pots and inside during winters, but we also have some parasites attacking the leaves.
    just check especially under the leaves and see if there is anything wrong.
    i'd say in cyprus such trees should otherwise do fine.

    Are your neighbors having any similar problems with their trees, Alex? Maybe that would provide a hint?

    I've inspected the leaves closely, not found any signs of insects/parasites.
    My neighbor have orange trees, they are adult and healthy. He said he have no idea what is wrong with mine, never had such a problem.
    So Ι think maybe it's overwatering. Will try το reduce watering and see what happens. Just ordered the moisture meter to control it better.
    Thank you all for your help!
