Diane from Kokomo, Indiana writes
A study had good results whereby 2" holes were drilled around pin oak and filled with 1/2 lb. MicroMax micronutrients, 1/2 lb. granular elemental sulfur, and about 1 lb. Oscomote 24-4-10. The last item is no longer available. Could the Andersons 24-5-11 product work as a substitute? Concerned because it appears to be designed for lawns.
Andersons 24 - 5 - 11 Fertilizer is only labeled only for turf use. A better product would be Ironite Lawn and Plant Food Plus 12-10-10.
