Hi all Smile

My wife and I have (about a month ago) replanted our lovely Clematis 'Rebecca' from its pot to a flower bed. When it was in its pot, it was growing enthusiastically, and in a stage just before it was about to flower.

Since replanting it in what can be described as a slightly clay soil with a bit of multi purpose compost added in for good measure, it hasnt been doing very well. When initially it had bright green leaves, a look of health and a bloom of flowers, its like its given up, and developed these brown spots on the leaves, and now the whole plant's leaves generally are lacking their 'green-ness'.

Im not sure if its a fungus, disease, or malnutrition - we've been watering our plants religiously with this stark lack of water of late. The rose adjacent to our clematis seems to largely be unaffected - with bright green leaves and only a few with brown spots on. I dont think its clematis wilt, it doesnt look like its wilting away and dying - just as if its very 'sick'.

Please help! Confused

Heres a better picture, of when we first planted, and how it is today:

This looks like a classic case of Powdery Mildew, this is a fungus that attacks leaves and stems of a few plants including clematis. At this stage of the attack the damage has been done although a spray with Vitax Two in One, a combined insecticide and fungicide will make the leaves look a little better.
This fungus is prevalent in warm humid conditions and is most likely to attack plants that are dry at the roots and possibly lacking nutrients.
Giving the plants adequate water and feeding the correct amount of food will to a great extent control this condition. It is not generally fatal to the plant and next year providing the plant has the right conditions may not be affected.
It is possible to spray with a fungicide once a month starting as soon as leaves apear in the spring, giving a additional spay during humid conditions, but I no longer spray for this condition or Black Spot, I still get these conditions from time to time, but they are no worse than in previous years and have learned to live with them.

Thanks for your comprehensive reply :)

We've been watering the plants as much as possible due to the dry weather, perhaps we've overdone it. Ill make a mental note to the feed the clematis more often, and Ill also give that Vitax spray a try.

Fingers crossed I can 'nip this in the bud' before any major damage is done next year.

Thanks again!
