To control weeds in your garden, late summer and early fall is the best time to make a difference

A horticulture professor recommends using late summer and early fall to stop weeds like crabgrass and dandelion from seeding, since a single mature plant can drop thousands of dormant seeds. The advice: slice annual weeds at the soil line, dig perennials out root and all while soil is moist, and clean tools between infested beds to avoid spreading rhizomes.

Herbicides applied now are said to travel more effectively into root systems as plants store carbohydrates for winter. The piece also advises against fall tilling, which can bring buried seeds to the surface, and suggests cover crops or thick mulch layers to smother bare soil before spring.
