Question
Something is eating on my clamitis. I've tried
several sprays but none even slow them down?

Answer
Hi Laura,
Thanx for your question.  Can you be a bit more descriptive please in what is going on with the clematis?  What have you used?  Have you seen any pests?  Aphids are a common pest and are usually on the underside of leaves.  Very small, green, yellow, white, black or reddish-brown.  You can use insecticidal soap on them.  Where are you located?  Let me know.
thx,
Tom
