Can't see the pics Ed click on the little tree icon in the toolbar above where you type your post and follow the instructions - hopefully that will do the trick
Thanks Dovefromabove I will get the hang of things.
Hi Edd, are these indoors or outdoors?
They are out side in pots. They are watered at soil level so i do not think it is sun scorch. It has spread to my mint and oregano, so not sure what is causing it.
I'm thinking that it could be rust ?
I am familiar with rust and this is not as aggressive as that and does not have the blisters on the outside of the leaves. It is actually inside of the leaves.
Something tiny eating away inside the leaf?
That's what I'm thinking too - some kind of leaf miner? There are a couple of UK species which can affect thyme and there is rosemary leaf miner.
I am not sure. It would have to be minute if it is. It does not kill the leaves off or damage them in any other way apart from the appearance.
leaf miners are small. I've never found one yet, just the evidence of their activity.
They're probably visible to a good naked eye but I can't focus down that far
Some info on miners affecting thyme here, Edd, although it probably won't help much in this format:
The more i try and read, the more it looks like THRIPS.
Could well be. You could try bringing one indoors, putting it on a large piece of white paper and brushing over the foliage a few times with your hand. Any thrips should fall onto the paper. Whatever the pest is, I'm not sure what you can do unless these are plants kept only for decoration as you wouldn't want to spray chemical controls onto anything you will use in cooking.
Thanks for your time Bob and Dove/Nut. That idea sounds good.
unfortunately i used all my herbs over xmas and trimmed the plants right back for the new growth in the spring. If it is thrips then i will have to use Nematodes and sticky traps to try and identify and catch them, as the eggs will be in the soil now.
Any idea where to get "hot pink" sticky traps or make them?
