Growing HAAS avocado in a pot- limit root size?
I just bought this grafted HAAS avocado tree. I know it needs full sun, but i have heard that the roots of this tree are OUTRAGEOUS! I am planning on planting this in a planter box. Would the box help control the root growth? What would be the best way to limit the roots from growing outrageously? Also do the HAAS roots spread or grow downwards?
