How to Fertilize Large In-Ground Established Plumeria
I'd like to organically fertilize a HUGE neglected plumeria growing in our backyard exhibiting some nutrient deficiencies (chlorosis, edge burn). I dare say that it has never been fertilized during its entire outdoor lifetime. However, the soil it is growing in is extremely compacted so digging or tilling-in compost or fertilizer is definitely not an option. Is it possible to topdress compacted soil and still get results?
