Garden weed control is most effective in late summer and early fall

Horticulture professor Manjot Kaur Sidhu of the University of Maine recommends that late summer and early fall are the most effective times for year-round weed management in gardens.

To prevent the spread of seeds, gardeners should prioritize cutting off seed heads and flower structures of mature weeds. For annual weeds like crabgrass, purslane, and pigweed, slicing them off at or just below the soil line with a hoe is an effective method that avoids disturbing nutrient-rich soil layers.

Unlike annuals, perennial weeds such as dandelions, field bindweed, ground ivy, and thistles survive winter via deep taproots or rhizomes. These must be pulled or dug out completely while the soil is moist to ensure the entire root system is removed.
