Something is eating the leaves on my Salvia Black and Blue. No sign of any bugs on the plants. I have a picture but don't know how to post it.
The only thing that gets on my Black and Blue is
cutter bees (besides whiteflies they don't mess with the leaves).If you could give a breif description.
Do you have hole's in the center of the leaves or along the edges?
For the first time ever I have budworms eating the new buds on the spikes of several different Salvias and the Eggplants. Something new every year.
One year I had Potato Beetles (Bugs) eating the Salvia leaves in one area of the garden. I dusted and that was the end of that. However, it is a little early for Potato bugs in your area, I think.
If you have small holes in the centre of the leaves, it could be minute caterpillars. I have these on a couple of guaraniticas. A systemic insecticide should help.
NO! the systemic will also kill the bees and Hummingbirds.
If it is catapillars use BT(Baccilus thuringensis var.Kurstaki)Thuricide or worm killer. It is organic /gives only targets the worm and being it is not a poison will not
hurt ladybugs, hummers or bee's. Lowes sells it as "worm Killer.
