Q.Drooping Loquat Leaf
Columbia, SC Zone 8 —Tree about 2/3 years in the ground . Plenty of sun . Not standing in wet soil. Planted correctly . I do water it but don’t feel as if I am overwatering. Leaves are continuously drooping, falling off . I feel more than a Loquat should . Getting new leaf but the tree has shallowed in leaf overall appearance . I have fertilized in past with a tree and shrub fertilizer , possibly too heavy . Ordered a 6-6-6 , should be here in a week and will begin the season with this . Is this the right course of action to amend the drooping leaf and force new leaf flushing for the new season ? What would the correct application of 6-6-6 be .. Thank you if you can help

Zone 8 is very chilly for a Loquat. They will survive quite fine, but they will lose many leaves during the winter. This is likely what happened and was mistaken for a lack of fertilizer. Adding fertilizer that is too rich will cause further leaf drop. Now, trying to correct it by adding more fertilizer could kill it.
Allow a year or so for the soil to clear out before adding fertilizers again. After this, they will need an all purpose lawn fertilizer or what you describe as a 6-6-6 will be fine. This will need to be done 2 or 3 times per year after this year's recovery. You will not need to feed them in winter, when they will be slower to grow.
