Since you're growing in a container it doesn't need to be grafted. Of course there are a few types of citrus that do better as grafted, like kumquats. Meyers do well on their own roots. I bare rooted my trees right after they came. As long as you do it before it gets too close to the end of the season you will be fine.

a rooted cutting won't be a dwarf then, correct? will that matter for keeping it in a container?

Correct. But for containers it doesn't really matter. Regular root pruning and repotting will keep the plant healthy and a reasonable size.

The Meyer lemon is a small bush anyway so you'll do fine.

thanks. i went with the 3 gallon size from Mckenzie. four winds was out of the 3 year grafted ones anyhow and mckenzie was cheaper on both the plant and shipping.
