My fertilizing and bug killing regimen is somewhat different. My greenhouse is attached to the house along with the heating system. Whatever I spray in the greenhouse gets circulated through the whole house. I also keep Fish in the greenhouse. So I am somewhat restricted what I use.
I will use the Bayer 3 in 1 when I move my Orchids outside, and then again in the Fall short before bringing them back inside, mostly on my Cattleyas. By February I am always seeing scale, which I clean up with All Seasons Horticultural Spray Oil and this Winter I have also used with good success SucraShield. The latter bought from firstrays.com
Fertilizing in the greenhouse is a real mess, it will deposit salts on the glass panes, hard to clean. I have used very little commercial fertilizer during the indoor season, instead I have watered with aquarium water twice a week (grandchildren's small feeder goldfish grew to ca 10 to 12 inches over the Winter and is now in our outside pond, the little Piggy ate like it and needed lots of cleaning
) with additions of some Epsom salt once in a while. I think the Phrags really love this treatment and I see lots of nice growth on my smaller species.
