The most you can do it assure you have planted in the correct soil and growing conditions.
Transplanting during active growth and blooming is not in the trees best interest, but I understand you have to do what you have to do!
Watering a newly transplanted tree is the most crucial step. Daily water for the first 2 weeks. Soil should be moist but never soggy.
Apply 3 to 4 inches of hardwood mulch to help with moisture retention.
Do not try to fertilize into health. This would further stress a tree.
