When is the best time to palnt fall bulbs in Chicago area?
I am in Zone 5a and north of Chicago. When would you recommend to be good time to plant fall bulbs? Searched on line and there are several versions. Some recommend plant right before the first frost, and some recommend to do it after the first frost to make sure ground is cool enough. I have been gardening for several years and have limited experience with fall bulbs.
Thanks in advance for your help,
