It's generally better to pull out dead annual plants rather than tilling them in. Pulling them out helps remove the plant material from the soil surface, preventing potential diseases and pests associated with decaying plant matter. After removing the plants, you can add a layer of mulch to help suppress weeds, retain moisture, and improve soil health. Tilling can disrupt the soil structure and may bring weed seeds to the surface, leading to more weed growth. Mulching over pulled plants provides a cleaner and more effective way to nurture your garden soil.
