If you planted bare root blueberry bushes this spring, you’ve likely watched them send out tender shoots, put on leaves, and begin to anchor their root systems into the soil. While blueberries are hardy shrubs, their first year is all about establishing a strong foundation. As fall approaches, your focus should shift from encouraging growth to preparing them for dormancy. The steps you take now will help your blueberries withstand winter and rebound with energy in the spring.

How Blueberries Transition in Autumn

By late summer, first-year blueberry plants start shifting their energy reserves. Instead of producing new shoots, they begin storing carbohydrates in their roots and stems. Leaves may take on red or bronze tones as the plant naturally winds down. Your fall care routine should work with this cycle: supporting root health, protecting against harsh weather, and reducing the chances of pests and disease overwintering near the bushes.

Watering and Fertilizer Adjustments

Stop all fertilizing by late summer to prevent soft, tender growth that frost will damage. Blueberries in particular are sensitive to nutrient timing, and encouraging new leafy shoots this late in the season can weaken the plant.

Watering is still important in fall. Keep the soil evenly moist during dry spells until the ground freezes. Blueberries have shallow roots, which makes them more vulnerable to drying out. Deep hydration before dormancy helps prevent root injury from freeze-thaw cycles.

Mulching for Insulation

Because blueberries prefer acidic, consistently moist soils, mulch is one of the best ways to care for them heading into winter. Apply two to four inches of pine needles, bark chips, or other acidic organic matter around the base of each plant. Mulch will insulate roots, regulate soil temperatures, suppress weeds, and conserve moisture.

Be sure to leave a small gap around the crown to keep moisture from accumulating against the plant base. In colder climates, adding an extra mulch layer provides additional insulation during the harshest months.

Protecting Young Plants from Cold Stress

Blueberries can tolerate cold, but first-year plants benefit from added protection. In northern zones, you can cover bushes with breathable frost cloth or burlap once temperatures plunge, particularly during sudden cold snaps. Snow itself acts as a natural insulator, but early-season frosts before snow cover can damage unprotected plants.

Container-grown blueberries should be moved into a sheltered spot—such as against a south-facing wall—or even overwintered in an unheated garage to prevent roots from freezing solid.

Clean-Up and Disease Prevention

Like other fruiting plants, blueberries can host pests and pathogens if fall cleanup is ignored. Rake away fallen leaves and debris from around the base of your plants. This reduces the chance of fungal spores or insects overwintering and re-emerging in spring. Prune away any dead, weak, or diseased branches once the bush is dormant, but save major pruning for late winter or early spring before new growth begins.

A Final Fall Checklist

Before the first frost, double-check your blueberry patch:

• Is mulch refreshed and properly placed?
• Has the soil been watered before freezing?
• Is the planting area free of debris?
• Are vulnerable young plants protected from frost?

These small steps now make a big difference in how well your blueberries come through the winter.
