I assume you want both a type A & a type B because you hope to get fruit, and if so, I admire your optimism--a fruiting, indoor avocado would be a real challenge! You won't need both A&B types for fruit, though; if you're lucky enough to get flowers indoors, you'll likely have male & female blossoms opening at the same time anyway. Buying a dwarf variety could conceivably help you grow it to a fruiting size indoors, and still have it be small enough to deal with. This article might be of interest.

Hello Aaron,

I'm very new to avocados- have just had one for about six months. I primarily grow plumeria and citrus, but have just one dwarf Fuerte avocado. Have a 16' x 16' indoor greenhouse which has 8 T5HO 4 foot lights. I also have some additional LED lights for the avocado and citrus trees. I live in a wet, cold and very grey year round climate, so everything stays indoors in the greenhouse.

My avocado is 4 feet tall and in a 5 gallon container. It's in a 5:1:1 soil (5 parts Repti-bark, 1 part perlite and 1 part Miracle grow potting soil). I water approximately every 5 days about 8 cups water. Fertilizer is a half dose of Osmocote, and then 1/2 dose of Foliage Pro and Pro-Tekt every other week.

I bought the tree from Four Winds. It looked terrific when I bought it but within a month leaves dropped and turned brown. Now it looks beautiful again- lots of green healthy leaves popping. I'm out of town at the moment but will post a pic when I get home. Best wishes.

Nancy
