It does not look well.
Fading yellowish leaves.
I have taken it out of direct sun.

What to do?
Any particular feed?

Hi Tracy,

A quick way of finding out if this is verticillium wilt or not is to cut a small branch/ twig off and look at the tissue beneath the bark. If you can see dark streaks or blotches then this is an indicator or verticillium wilt. There is unfortunately no cure for this, and all you can do is remove the tree altogether and replace with a resistant alternative.

If there is no dark streaking it could just be that it is suffering in the heat. Try watering, feeding with a liquid feed, and applying a mulch to prevent too much evaporation from around the roots.

Hope this helps! Don’t forget to add to your ‘plants I have’ list to receive regular care updates. http://www.shootgardening.co.uk/plant/cercis-siliquastrum

Tracy, it might be fungal leaf spot. If it is, looking closely you may be able to see concentric rings on the spot and minute fungal bodies in the centre. More common on plants not growing strongly and in damp weather. Pick off affected leaves and spray with systemic fungicide. Good luck. Ian
