My four apple tree and one pear tree they all got curling leave is there anything I can do for them .I got some pictures this morning see anyone can help.
If they are all in pots, perhaps lack of water and nutrients? Are they varieties suitable for pot cultivation ?
Your photos don't really give much of an idea as to pot size so that could be an issue. Where you have them sited could also be something to consider.
Perhaps a bit more info may elicit some useful advice ?
