bearded irises; also, how often to feed azaleas and other flowering shrubs in the summer
I have many bearded irises which need digging up and replanting. How early after blooming can I safely dig them up and replant them? Also, what should I add to the soil when I replant them? (I live in north New Jersey.) On azaleas, my bushes have a moldy look on many branches. There are still some branches which still look alive, but for the most part, the shrub looks like it is dying. I went to a local nursery, and they told me I might try spraying with insecticidal soap to save them? Is this correct? As to my healthy azaleas, how often should I feed them in the summer? Thank you
