Q.crabapple tree
I ordered three bareroot crabapple trees. They are VERY small. Should I plant them in a container until they get bigger…then plant in ground next spring?
Also, I am planting them in an area that I have tried four times to plant a tree without success. Is there a pH level crabapples prefer? (It is full sun, and being in Louisiana, it can get really hot and humid).
Last, can I plant all three crabapples close together?
THANK YOU!

In a proper planting area you should be able to plant out the bare roots now.
You may want to cage them and flag them so that they are not harmed by accident!
Regardless of soil type, it is crucial to have well draining soil.
The ph should be slightly acidic at 5.0 to 6.5
