The Proper Method For Applying Slow Release Fertilizer to Large Established Container Plants
I have 150 container plants (mainly resin) of varied sizes (15 each 20 gallon containers 100 each 10 gallon containers and the rest varying from 1 gallon to 5 gallons) that are perennials. There are many varieties of herbs along with “wild” flowers and camellias, tea olive, hollies, nandinas, gardenias blueberry blackberry, etc. All are recommended for my growing region (8A). My question: what is the PROPER way to feed Osmocote to these plants? I have a 2-inch mulch of shredded cedar on top of each container. Most of the plants are young (planted in Spring 2018). They were planted with new pots and fresh Miracle Gro potting soil which includes fertilizer and perlite/vermiculite mixed in.
Fall is approaching and it will have been 6 months since any fertilizer was applied. So as to not over-fertilize I depended on the existing fertilizer in the potting soil – so I have not fed Osmocote yet. My question is the specific method of application and is fall an okay time for applying the Osmocote to them? Thank you, Larry Croft. Martinez Georgia
