Should i stay on the same schedule of after fathers day to do anything to the tree.

San Antonio - July is HOT, and DRY. I would avoid repotting during the most brutal part of the year. I think where you are at you should move up the schedule. In IL and MI, the middle of June is about 1 to 2 months after the last frosts. After the apple trees are done blooming, but before cherries and early stone fruit are ripe. San Antonio is probably one to two months ahead in the season. I would probably repot in April or May, as Vance suggested when needles are fully open and extended.
OR - I would wait and repot after the weather has begun to cool, late August or September. In San Antonio, find out when you get your first frosts, as long as you repot 2 months ahead of first frosts you will probably be okay. Your winters are quite mild. This autumn repotting might be better than any other time. I believe some years San Antonio does not go much below 32 F all winter. In a very mild winter climate, autumn repotting might be a much better choice.
If you can, give the tree a year to adjust to Texas weather before repotting. The tree might be better off, and it will give you some time to get familiar with exactly how the weather typically runs through the year. In San Antonio it makes a difference if you are in the "hills" or down low. Two fairly different micro-climates.
I've only visited San Antonio once, but I worked one year in Dallas, and the summer is brutal. Factory was not air conditioned, fortunately the lab was. I know how the heat affected me, I can't imaging trying to keep a tree hydrated after cutting off roots just before the heat of summer. The more I think about it, the more I think a late summer - early autumn repotting schedule might work better for many species in that climate.
There is a bonsai nursery in Austin, and a pretty active bonsai community. Seek them out, and find out what locals do for their trees. Granted they will be talking about different species, but they will be able to let you know how trees respond to the brutal summer heat and drought. I forget the name of the nursery, anyone out there can help?
