Citrus in containers
I ordered a Washington naval orange tree. It is 6 feet tall and has lots of branches. I planted it in 10 gallons container. The soil I used is 1/3 soil with humus 1/3 sphagnum moss and 1/3 perlite. I water 1/2 gallon of water with 1/2 ounce soluble miracle grow 3-1-2 every week. I got in now with three no heat flourcent lights because of the weather. But to my dismay the tree is losing its beautiful leaves. Is that normal or the pot is too small. Also I ordered two trees one Tangelos and one is lime. I have pots of 10 Gallons. 15 gallons and 20 gallons. Which one is suitable? All these trees will get out in the Garden by mid-April.
