From your description, we do not believe this is Mimosa wilt, but have provided a couple of online resources for more information. Albizias do best in well-draining soil, regular water, especially when young, a layer of mulch and feed with a slow release or organic fertilizer formulated for trees. Here are some more specific tips, but suggest you contact a horticulturist at your local garden center familiar with mimosa trees to confirm that this is not a disease but tip burn resulting from irregular water:
1. Apply a 3 inch layer of mulch out to the dripline of the tree allowing 2-4 inch space around the base of the tree
2 Needs 5-inch depth of water during first summer planted and then decrease to watering down to depth of 1 inch every 7-10 days except during rainy weather
3 Check for signs of pest infestation or disease periodically looking for wilted growth, galls on trunk or slowing growth
4 If an arborist or horticulturist familiar with Albizias confirms it is Mimosa wilt, you may have to destroy it based on their recommendation
