The outdoor thermometer the other morning read 47 degrees at 7 a.m. There’s no denying it: We’re heading toward fall.

September is one of my favorite months in the garden. The frenetic activity of early summer to get things started and the heat of July and August are absent. But that doesn’t mean there are not things to do. Here are 10 pleasant September garden chores to enjoy.

crocus to plant in September

Planting bulbs, such as crocus, in September will brighten up your spring.

Purchase and plant bulbs. If you haven’t bought spring bulbs, consider helping MSHS and buying them from Brent and Becky’s Bulbs and selecting MSHS. Twenty-five percent of your purchase will come back to our education and outreach programs. Whether you shop online or in a local nursery, mid- to late September is the best time to plant bulbs for spring bloom. Are voles, moles or rabbits a problem in your garden? Plant daffodils — they seem to be immune to critter munching.

Clean up spent/diseased vegetables. If your tomato plants have blight or septoria leaf spot and production is diminishing, it might be time to pull them. Don’t compost diseased plant material unless you have a compost pile that gets really hot. Pull the plants and throw out the debris.

Plant something fast-growing. If you have a hole in your garden, you might want to plant a quick-growing lettuce, arugula or radish. Some vegetables can take a bit of frost and grow fast enough to give you a crop before the end of October.

Plant a cover crop. You may want to even plant a cover crop to nourish your soil for next year’s garden. Courtney Tchida will be teaching a webinar on cover crops and soil fertility for northern gardeners Sept. 15, if you want to learn more.

Plant a tree! Fall is the best time to plant a tree in your yard. It’s easy on the tree and you may get some great deals at the nursery. Two things to remember when planting trees: don’t go too deep—you want to see the root flare above ground—and make sure to water it (probably daily) for at least six weeks. Your nursery or garden center will probably have a guide for you to follow. Here are some recommendations for trees that will do well over the next few decades (yes, think decades!) in Minnesota.

Plant perennials. It’s not too late to divide or plant perennials, too. Don’t give them too much fertilizer, but make sure they are adequately watered through the fall.

Add a fall container. A fun activity to put on your September garden chore list is adding a fall container. Mums, decorative pumpkins, ornamental kale — whatever you like to add something fresh to your front porch or stoop.

Start garden clean up. I try to leave up as many plants as I can for pollinators through the winter, but some parts of the garden need cleaning up. Deadhead. Pick your weeds. Remove dead vegetable matter.

Start transitioning houseplants indoors. One important September garden chore is to start transitioning any houseplants that may have spent the summer outside back into the house. You’ll want to clean plants and the pot and make sure there are no bugs on it before bringing them indoors. Our friend Amy from GetBusyGardening.com has a great post on how to clean and debug your pots.

Take care of your lawn. Early fall is a great time to fertilize, spread seed or patch your lawn, apply broadleaf weed control, thatch or aerate, if any of those are on your agenda. The University of Minnesota has great information on when and what to do in the lawn.
