Re; Rosemary infestation
 

We already have lost one of our potted rosemary bushes and now the same critters
have struck our second and last one. Whatever it is leaves a fine web and tiny black
nodules. The infected part withers away.

What is doing this, and can be done about it?

TIA

Hi Ed,

This is probably red spider mites.

I control them by using a hard stream of water from a hose and blasting them off the plant.
I have one rosemary in my garden, and I have been doing this for the last five years.
It doesn't get rid of them completely, but it does keep them under control. This rosemary
started out as a 1 foot tall plant in a 1 gallon pot, it is now 4 feet tall, 7 feet from front to back
and 9 feet from side to side.

So check your gardening books for listings on red spider mites.
