Essential autumn gardening tasks to prep your lawn and plants for winter

Autumn brings key tasks for gardeners looking to prepare their lawns and plants for winter. From fertilising grass to storing harvests, the season demands attention to detail. Experts also recommend sustainable practices that have grown in popularity across the U.S. in recent years.

Lawn care should start with fertilisation in early October. This timing helps create a thick, healthy turf but does little for summer weeds. Minnesota's guidelines suggest using slower-release nitrogen and cutting back on phosphorus, based on soil tests. The state also advises fertilising in spring and autumn rather than summer, a shift seen nationwide between 2021 and 2026 to reduce environmental impact.

Perennial broadleaf weeds can be treated with selective herbicides this month. Meanwhile, dark green patches on grass may signal low nitrogen levels, often caused by dog urine. Removing diseased plant parts now will help prevent future pest and disease problems. For indoor plants, positioning them according to their winter light and temperature needs ensures better survival. Outdoor harvests should be gathered before the first frost, though some fruits, like tomatoes, can ripen indoors. Winter squash and pumpkins need curing for proper storage. Gardeners can mark branches on trees and shrubs with tape over winter to identify what to prune later. Those seeking extra guidance can listen to WCCO Radio's *Smart Gardens* show every Saturday from 8-9 a.m. The *Smart Gardens* podcast also offers advice for busy gardeners.

Following these steps will help maintain a healthy garden through the colder months. Sustainable fertilising, timely weed control, and proper plant storage all contribute to better results next year. Local resources like radio shows and podcasts provide ongoing support for gardeners at every level.
