I have a newly planted Photinia ( a couple of months ago) that was thriving, today I have noticed all the red leaves are brown and shrivelling. Next to it is a hydrangea that has been fine for a few years, and now again the leaves are shrivelling up with brown on the edges. The hydrangea has looked poorly for a few weeks. I am wondering if I need nematodes, which I have used a few years ago, in almost the same place in the border. But there are so many nematodes on the market I don’t know which one I need. They used to be just basic Nematodes. I can’t see anything in the earth. I have also spread some tea leaves around the plants a couple of weeks ago, could this be the cause? And watered regularly. Thanks all.

Its frost damage - 100% sure.

Ah! Hadn’t thought of that, thanks Polly.

I'm no gardener but even before I saw your picture (or read APG's reply) I was thinking "frost, surely!"

The same has happened to my hydrangea and buddleia - think the frost has nipped them and hope they will recover.

My garden looks like a snow storm has hit it -all tender plants covered with white frost protection, though I've lost a lovely california lilac to the frost and a hydrangea that was supposed to be hardy down to minus 15C!

Maggie -the buddleia should spring back and you need only prune off the dead shoots. If you have'nt pruned back the Hydrangea too hard buds should appear further down the stems or from the base -although as hydrangeas flower on last years growth you won't get any flowers from the growth at the base.

What about the Photinia? It had lovely bright red leaves...

[AuntPollyGrey]

Plenty of good info here , but basically cut off all the dead / damaged leaves and it should recover no problem.

Thanks, a job for me tomorrow!

My first thoughts was frost damage too.

PS, Leave any pruning until all fear of frost has gone!
