pruning miss kim lilac when she's gone crazy

Asked August 12, 2017, 3:41 PM EDT

Hi, i have a Miss Kim Lilac in a very small yard and she's about 7-8 years old, it took 3-4 years to bloom, but now does relatively well, though only one fabulous year.
It has grown 'weedy' in that it has multiple main stems and off shoots, and I hadnt pruned it earlier because they said 'it doesnt need trimming', and to do mild trim right after blooming. But this is major (out of shape, uneven, too wide),can I do major prune this fall, then no blooms next year, but will it recuperate for the following year?
thanks, Diane

The name Miss Kim Dwarf Lilac (Syringa patula 'Miss Kim') can be deceiving; since it's 'dwarf,' people figure it must remain small. In fact, it gets to be about 5+' tall over time and is dwarf only when compared to the old-fashioned common lilac which gets about 10-12' tall.

You can go ahead and prune now if you have to, but you will forgo flowers next spring. Here's a good article on pruning flowering shrubs: http://www.ext.colostate.edu/mg/gardennotes/616.pdf
