The episode provides a comprehensive guide detailing ten essential late fall and early winter gardening tasks crucial for ensuring a vibrant, pest-free landscape the following spring. These vital duties begin with aggressively removing diseased plant material and debris to prevent the carryover of pests and pathogens, while also focusing on improving the soil amendment and enrichment of beds through the addition of compost or cover crops. Practical steps outlined include planting spring-blooming bulbs before the ground freezes and dividing overgrown spring- and summer-blooming perennials to reduce root competition. The guide also emphasizes applying protective winter mulch correctly after the ground cools and protecting vulnerable species, such as wrapping the trunks of thin-barked trees and shielding tender evergreens. Finally, the episode reminds readers to clean and store all garden tools and containers to prevent damage and disease spread, rounding out the season with crucial time spent on planning and ordering for the next year.
