Hi. I have a sticky substance on my Rhododendron, Acer and now starting on a Clematis, it's a bit like i have on Petunias in late summer. What do you think it is and how do i control it please.

The sticky is most likely caused by insects. Aphids are a common "sticky" sort of bug as are mealy bugs. If it is bugs, most can be sprayed with insecticidal soap to kill them.

Can you take pictures of the sticky leaves? Pest bugs are usually on the undersides of the leaves, rolled up in fresh growth or sucking on the tips of the new growth.

My car is covered in a sticky liquid everymorning now. It is parked under oak trees that are just about leafed out.
The sap is dripping from the new leaves, the catkins and probably 23.5 gazillion insects feeding up there. Just very messy. Not all sticky stuff is cause for alarm.
