Answer: Your Santa Rosa will set more fruit if there is a suitable pollinator in the neighborhood. Some suitable matches for your Santa Rosa plum include Beauty, Fortune, Hollywood, Santa Rosa, Methley, Cocheco, Shiro, Sprite, and Delight. Without a second plum tree nearby, the fruit set will be sparse.
Plum trees should be fertilized annually for best growth and development. Use a 10-10-10 fertilizer and broadcast the product under the canopy of the tree. The general suggestion is 8 ounces of 10-10-10 per year for each year of tree age. Hope this helps!
