I have spider webs and small tan bugs on my miniature roses. The leaves have all dried up and falling off. What can I do to control this problem? I have sprayed them but it hasn't helped.

It sounds like you have an infestation of spider mites which leave those webs you're finding on your miniature roses. Spider mites are tiny, and live on the undersides of the leaves. They love hot, dry conditions. One of the best ways to deal with them is to literally spray them off with water every time you water the roses. Be sure to spray the bottoms of the leaves as well as the tops. This should knock them off. Often, regular sprayings with insecticidal soap will control the mite population. If you use a miticide be sure to follow the directions closely. You probably need to spray more than once. One spraying will usually not cure the problem.

A technique that has been successful for me is to make a froth of soap suds and dab it onto the plant being sure to cover it entirely-top and bottom of leaves. This will suffocate the mites and won't hurt the plant at all. You might give this a try.
