Geraniums not blooming well
Hi I live in northern Illinois (Zone 5) and I have a grouping of perennial geraniums (cranesbill) that didn't bloom very well last year and this year they look very leafy but don't seem to have many buds on them. They're about 9 years old and I've never divided them. Should I be doing this and if so how ? Are they just too old ? Not sure if something like Miracle-Gro would help them bloom better. Thanks, Karen Black

It's possible that your perennial geraniums need dividing or thinning. Some types spread quite quickly while others remain in a tight clump for many years. If they appear to be growing in a thick mass, you can simply dig out sections to transplant elsewhere (or discard if you have no place to plant them). The remaining plants can then fill in the bare spaces, and with less competition may indeed bloom more profusely. If you haven't fertilized in quite a while it would be helpful to do so. Make sure that you use a fertilizer for blooming plants (one in which the first number[nitrogen] is relatively low). Too much nitrogen forces leafy growth at the expense of blooms.
