The answer to 'why is my shrub weeds' is that your shrub may be overrun with unwanted plants, also known as weeds. This can happen for a few common reasons: poor soil conditions, inadequate maintenance, or the introduction of weed seeds from outside sources. Weeds can compete with your shrub for water, nutrients, and sunlight, stunting its growth and causing it to look unsightly.
To address the weed problem, you'll first need to identify the specific weeds and their growth patterns. Then, you can take steps to remove them, such as hand-pulling, applying herbicides, or mulching around the base of the shrub. Improving the soil quality and providing proper care for your shrub, such as regular watering, pruning, and fertilizing, can also help prevent weed growth in the long run.
