What's up with my apple tree please?

[mrbadexample]

Hi all,

I have a family apple tree which I've released from its pot and is now in the ground. Today I saw leaves looking like this:



They're a bit on the crispy side too.

The problem only seems to be affecting one of the varieties (don't ask which as I've long since forgotten what they are).

Any thoughts?
Cheers, MBE

Its got mildew - pick off the infected leaves and bin them - keep an eye on the rest - hopefully it won't be serious.

Powdery Mildew

It’s powdery mildew, which can be very common on some apple varieties.

Here is the RHS advice which should help you.....

Thanks both. Does this mean I should have watered it more?

There's always a bit of this about - seems to be worse in warm dry weather - if the tree looks distressed then stick a hose under it for 30 mins to give the ground a soaking round the roots.

if its a young tree, then sometimes a foliar feed with something like seaweed fertiliser, will perk things up a bit.

Thanks, I'll bear that in mind.
