Something Is Boring Into Stems Of Geraniums

Question From: H. van Heerden - Luxemburg City, Luxembourg, Luxembourg
Q: I am from South Africa and I am in need of some help with a number of my geraniums. It looks like something seems to be boring into the stems. The plant is still growing but obviously not looking to healthy. What can I use to spray them with?

A: I recommend a product that contains Spinosad - which is environmentally friendly when used according to package directions and is effective on most pests. Best And Happy Yardening, Nancy.
