Leaf Holes (with Pics WOW!!)
I have a Sunny Wind Hibiscus that recently started getting leaf holes by some critter. Right now about 30% have holes. I've had this hibiscus for about 3 months. I have a drip sprayer on it that needs to be changed as I feel it's insufficient, so I've been watering by hand when it needs it based on dry soil which has been quite a lot lately here in SoCal. Is a sprayer bad for a hibiscus?
I've taken several photos that show this hibiscus, it's problem and a possible culprit which looks like a beetle of sorts. If you're not familiar with ImageShack, simply click "Next>>" on the right side.
If this is what's eating my hibiscus will a BT killer do the trick? If not, what will?
Thanks for any help.
