One of the most overlooked times in the pollinator year happens after summer’s peak bloom.
In many parts of the United States, gardens are overflowing with flowers in June and July. By late summer and fall, however, many ornamental beds have faded or already been cleaned up.
The insects haven’t disappeared.
Newly mated bumblebee queens are still feeding heavily, building the fat reserves they will depend on while overwintering for months. Honeybee colonies in colder regions may still be gathering nectar for their winter stores. Some late-season solitary bees are still nesting and provisioning brood cells. And migrating monarchs depend on nectar-rich flowers to fuel their southward journey—up to about 3,000 miles for some eastern monarchs traveling from the northernmost part of their range.
This is where a slightly “messy” yard can become remarkably valuable.
Goldenrod, native asters, boneset, Joe-Pye w**d, ironw**d, sneezew**d, wingstem, smartw**d, thoroughwort, and other late bloomers can provide nectar and pollen when fewer flowers remain. Goldenrods are especially valuable: the genus supports numerous pollen-specialist bees and serves as a host for more than 100 species of caterpillars.
A heavily tidied garden, meanwhile, may offer little more than mulch.
Want more fall flowers next year? Choose plants suited to your region that bloom late in the season. Depending on where you live, possibilities include New England aster, aromatic aster, native goldenrods, Joe-Pye w**d, ironw**d, blue mistflower, obedient plant, and anise hyssop. Sedum ‘Autumn Joy’ is not native to North America, but its late flowers can still provide nectar for visiting insects.
And you can help this fall without buying anything.
Leave part of the yard unmowed. Let volunteer goldenrod and asters finish blooming. Skip the urge to cut every perennial to the ground. Leave some stems, seed heads, and fallen leaves through winter, then tidy gradually once spring is well underway.
Pollinators don’t necessarily need another trip to the garden center.
Sometimes the most useful thing we can do is simply leave part of the garden alone.
