I have just located my 4 cymbidiums outside to spend the summer in my garden in a place where it will receive direct sun only in the morning until 12 noon. How can I prevent them from being attacked by scale, aphids, etc? Is it necessary to spray to prevent this from occurring?
I have my Cym outside and I have not had anything go after it yet. I control the slug and snail population in my garden in total but aside from that I don't do anything special until I notice pests.
If you have a current insect problem, or you are worried you will I'd have a stand by bottle of Bayer Rose insect killer. You can get it at Home Depot or any other store like that I think. It will protect your orchids both inside and outside.
