howdy peeps ,
need some advice please ,dug these self sown plums up late winter bare rooted them root pruned and potted them up .
have been giving them fortnightly feeds of seasol and charlie carp.2 of them have come out with curled up leaves and stunted growth and one has gone ahead leaps and bounds
any ideas
keen to sort the problem as the first tree is one of my shohin entries

There are a number of reasons why plums sometimes have stunted and curled leaves. The two most common (in my experience anyway) is getting a whiff of Round-up, or aphids or aphid bourne diease. Either way the leaves should start growing properly as the season progresses.

thanks Rowan,
pretty sure they havent got a sniff of round up ,to my knowledge anyway ,i am good to my neighbours
did find a few aphids on my J maples but only one plant and a dozen or so of the buggers tops .
fingers crossed you are right about the season progressing
cheers

Hey Rawhide,

My pet disease at the moment, which I'm seeing absolutely everywhere, even where it doesn't exist, is ammonium toxicity.

Not saying it is, but I thnk it is. If that makes sense.

Ammonium toxicity????
Do you mean Ammonia?? or Aluminium??? toxicity

Rawhide says he's been giving them Charlie Carp but it would have to be pretty strong to cause Nitrogen (ammonia) toxicity, esp in pots. Aluminium toxicity shouldn't affect plants in potting mix either - as far as I know only a problem in highly acid soils and only for Al sensitive plants.

I'd back off on everything, and just water with plain water. giving a dose of confidor or something of that nature wouldn't hurt either. then wait and see
