Hello, im hoping someone might know what's happening with these plants? The first is an Hydrangea Macropylla and the second one an Hypericum Inodorum Golden Beacon. Many thanks in advance

I had a similar problem with one of my shrub roses earlier in the season and it was thrips. Don't know if this is the same thing but I treated mine with a garlic spray that someone on another gardening forum recommended and I cut off a lot of damaged buds, flowers and leaves and it's now flowering ok.
Your Hydrangeas foliage appears OK ; could be water damage from last Wednesdays driving rain .
The second picture looks like Hypericum rust fungus ; you could cut to ground and treat regularly with Bayer Fungus Fighter , or try spraying it onto the current foliage to see if it helps . Not particularly brilliant advice , but may be helpful .
I reckon the hydrangea just has weather damage - some rain followed by wind or something.
Your St John's Wort has rust - lovely plants but they end up with rust so easily. I cut mine right back to the ground when they go rusty - I don't compost the cuttings.
It'll come back again next year and look fine until it finds an excuse to get rust again

Thank you everyone. The foliage on the Hydrangea also has some damage.. I attach a picture in case it helps diagnosis..
When you say to cut the Hypericum to the ground, do I really cut it all off? Not leaving anything? Sorry, very New to gardening!
thanks again.
Hypericums readily regenerate from the base ; has your Hydrangea been dry at any stage in its pot?
They fare much better in the open ground in a moisture retentive soil .
The leaf damage was likely caused by a nip of frost as the new foliage was forming.
It's a fine healthy plant - nowt to worry about and as Paul says it would be much happier in the ground and kept well watered.
Yes you can cut the hypericum right back to the ground - it'll re-appear

Thank you all!!!
