When is the best time to plant cosmos flowers in the suburbs?
I’m planning my garden for this season and want to make sure I'm timing my cosmos flower planting just right. I’ve been gardening for a while, but I’m not entirely sure about the best planting window in my suburban climate. I’ve heard that they thrive in warmer weather, but I’ve also had issues with late frosts in the past. I want to ensure I get them in the ground at the right time to maximize their blooming potential. Has anyone figured out a foolproof schedule for planting cosmos that works well in suburban areas?
