re: citus tree help

Citrus trees have a big root structure. As several posts have already advised against these in pots I would agree.

As for berries. I bought 2 blueberry seedlings about 8" tall 4 years ago and put each of them in40 gallon pots. Cut 3/4" plywood to go underneath and attached wheels so they could be moved around on patio. Bushes are now over 3 feet tall and produced a lot of blueberries that were awesome. Birds and squirrels love them also so you have to net when they start to turn colors. Pots for blueberry bushes worked well for me.

Citrus... we have 6 citrus trees and a couple of Ponderosa lemon trees. If I could have a do-over I would plant all N33s. N33s are like an orange you would get from Florida. We have Mandarin, Satsuma, etc... but my 2 N33s are amazing. They don't grow as fast as other citrus trees but the fruit is fantastic. Just my opinion.
