As a rule, here at Charella, we only sell the more established plants of 5 litre or more. We want to offer the customer an already established, winter hardy plant. You will receive your plant in a Nursery Pot that encases the rootball if you are not planting in the ground ideally you will need to repot into something larger. With this in mind we have compiled a rough guide to sizing. Obviously pots can be of different depth, shape etc.. but if you use the table below it will give you an indication of size.
For fast growing plants such as Bamboo its recommended you jump several sizes otherwise you will be repotting annually.
