We have procrastinated and did not get our trees planted this spring, they are still in 5gal. pots and appear to be thriving. It is not likely that we will be able to plant before July. We are in zone 9b and it's starting to really warm up. As long as we keep watering will they be ok in the containers until early July? Should we just wait until Fall to transplant? Thanks for your help!

There can be differing opinions on this; but I would plant them out.
As long as you water daily for the first two weeks and then watch them carefully for soil moisture they are likely to be less stressed then in containers for the summer.
Add 3 to 4 inches of hardwood mulch to help with temperature and moisture levels.
