How I Prepare My Flower Gardens for Winter

Where I live in Missouri, preparing the flower gardens for winter isn’t always as simple as following the calendar. By November, many of my neighbors have already cut back their gardens and consider the growing season over. I understand that, but when I look around my own garden, I still have coneflowers, zinnias, roses and four o’clock flowers blooming. My zinnias, in particular, are still covered with flowers, and I’m certainly not going to cut them down while they’re still blooming.

After years of gardening in Missouri, I’ve learned to let the garden tell me when the season is finished rather than deciding simply because the calendar says November. In the meantime, I begin preparing my garden beds for winter a little at a time by collecting seeds, making use of spent flowers and cleaning up the areas of the garden that really are finished.

๐ŸŒธ If It’s Still Blooming, I Leave It Alone

My zinnias are annuals, but they’re still covered with blooms, so I’m not going to remove them while they’re still flowering. I’ll wait until colder weather finally brings their growing season to an end. As some of the blooms become spent, I allow them to dry so I can harvest the mature seeds before removing the plants from the garden.

I treat the rest of my flower gardens much the same way. If a plant is still healthy and blooming, I enjoy it. If it has finished for the season, I begin preparing that part of the garden for winter. For me, fall garden cleanup doesn’t happen on one particular weekend. I work on it a little at a time as different plants and areas of the garden finish for the year.

๐ŸŒฑ Collecting Seeds for Next Year’s Garden

While I’m waiting for the rest of the garden to finish blooming, I’m already collecting seeds for next year. I cut some of my spent zinnia blooms and allow them to dry so I can save the seeds. My four o’clocks produce hard, round black seeds that are easy to spot and gather.

I collect the seeds as they become available rather than waiting until I’m ready to clean out the entire garden. It’s one of the things I enjoy about this time of year. Although the garden is slowing down, it’s already giving me a start on next year’s flowers.

๐ŸŒน Making Use of My Spent Roses

My roses don’t go to waste either. As the blooms fade, I harvest the spent rose petals for homemade potpourri. It’s one more way I can enjoy my garden after the flowers have finished blooming while making good use of something I might otherwise toss away during fall cleanup.

๐Ÿ‚ Cleaning the Parts of the Garden That Are Finished

Of course, some areas of my gardens really are finished by this time. Once the annuals are completely spent, I remove them. With perennials, I’m more selective about what I cut back and when. I also go through the beds by hand to pull wild grasses and weeds. That’s one job I would much rather complete in the fall than find waiting for me in the spring.

I remove unhealthy plant material as I work, but I don’t feel the need to strip every flower bed completely bare just to make the garden look finished. I’m preparing the beds for winter while allowing the plants that are still growing and blooming to finish their season naturally.

๐Ÿ Why I Wait Until the Leaves Are Gone

I’ve learned from experience to wait until the leaves have fallen and have been removed before putting down my final layer of winter mulch. In the past, I prepared my garden beds and spread the mulch too early, only to have my husband come along later with the leaf blower. While removing the fallen leaves, he would inevitably disturb some of the mulch I had just put down.

Now I wait until most of the leaves have fallen and have been cleaned up. I can weed the beds, collect seeds, remove spent annuals and cut back plants that are ready, but I hold off on the final layer of mulch. It may be a little colder than I would like by the time I spread it, but at least I don’t have to worry about the leaf blower disturbing the work I’ve already done.

๐Ÿงค Mulch Is My Final Step

Once the leaves have fallen and have been removed, I’m ready for the final step in preparing my flower beds for winter. That’s when I add my winter mulch.

For me, mulch is the finishing layer rather than the beginning of fall garden cleanup. I use it to provide added winter insulation, particularly around shallow-rooted plants and in areas where I have spring bulbs growing. By the time I begin mulching, most of the other work has already been completed. I’ve collected the seeds I want to save, cleaned the spent areas, pulled the weeds and waited for the leaves to come down. Once the mulch is in place, the flower beds are ready for winter.

๐ŸŒท Being Careful Around My Irises

My irises receive somewhat different treatment because their rhizomes grow near the soil surface. When I’m working around them, I’m careful where I place the mulch because I don’t want to bury or disturb the rhizomes. In early spring, I check the irises again and remove excess mulch from around the plants as the garden begins waking up.

๐ŸŒผ Enjoying the Last of My Fall Garden

My neighbors may have already put their gardens to bed for winter, but mine isn’t quite ready. As long as I still have flowers blooming, seeds to collect and roses to enjoy, I’m in no hurry to declare the gardening season over.

Eventually, Missouri’s colder weather will make that decision for me. My zinnias will finish blooming, I’ll collect the last of the seeds, the remaining leaves will come down and I’ll finish preparing and mulching the garden beds. Until then, I’m happy to enjoy every flower for as long as it lasts.
