Do you have any other citrus growing well in ground?If you do, then just graft the Meyer lemon to the tree that is doing well.
If your soil is PH 7 you should do fine. You can also plant it in a raised bed.
It is unlikely that Carrizo will grow. unless you have a large raise bed. Seville sour orange rootstock does well with higher PH soilsAre there any that do well with high PH and have good cold tolerance since I’m in 8b?
A pH of about 7.8 is the highest pH level that a Carrizo rootstock will grow. Above that pH don't even try.
