Morning Ladies,

Has anyone managed to get rid of these black beetles before their plants were demolished?

The Garden Centre only has 1 litre of pesticide available and only 1.5ml is needed (as a diluted spray) once and again two weeks later!

My Mum mentioned Derris, but not sure if this is available here.

Any other suggestions would be welcome :)

TIA

If it is the same black beetles that were eating my plants then they seem to breed in the soil at the base of the plant. Fortunately mine were in pots but I had to throw the whole thing away! :angry:

I got a huge bottle from Dubai garden centre (and you dilute 10ml of oil with 1l of water so it'll last me decades), but last week I happened to see that Speedex (near Natuzzi on SZR) had smaller bottles. It's worth a try!

OK. Looks like I'll very soon be googling "how to cut back plants"! Thanks for your replies.:)

Sorry no I've tried two or three and also tried my usual of washing up liquid and water well diluted. I've cut them well back before and they've always done well, but never had to do it for this reason before. I did notice that one or two branches just came out of the ground though as they were rotten at the bottom!!

I'm not holding out much hope here. Apart from these little b*ggers, they seem to be quite hardy plants, so hopefully yours will grow back. Can you remember the name of the pesticide you tried?

Yep tried all sorts and I was getting more worried about my other plants which was why I took the drastic action of cutting it right back.

Oh dear GE, that's not good! Have you tried a pesticide at all?

No!!! I've tried everything and nothing has worked. I've now cut it down to ground level in the hope that it will eventually re grow and to save my other plants from becoming infected.
