The answer to 'how to care for weed control' is to use a combination of manual removal, pre-emergent herbicides, and spot treatment of existing weeds. Start by pulling weeds by hand, making sure to remove the entire root system. Then apply a pre-emergent herbicide in early spring to prevent new weeds from germinating. For existing weeds, use a targeted spot treatment with a post-emergent herbicide to kill them at the root.
It's important to follow the manufacturer's instructions carefully when using any herbicides, and to take precautions to avoid harming desirable plants. Reapply pre-emergent herbicides every 3-4 months, and spot treat weeds as needed throughout the growing season. If you have a severe weed problem or are unsure of the best approach, it's best to consult with a professional landscaper.
