How to clear invasive weeds in garden?
Invasive weeds of your garden requires a combination of methods and strategy to prevent regrowth. Here’s a practical guide to approach:
-
Identify: Know the type of weed some invasive weeds like Bermuda grass spread by roots, while some reseed aggressively.
-
Manual Removal: Pull manually, get the entire root especially tap-rooted weeds. You can also use a weeding tool or hoe for deeper digging .
-
Smothering: Cover the soil with cardboard, newspaper, or fabric, and add a thick mulch layer. This blocks sunlight and kills existing weeds.
-
Solarization: To cover the large area apply clear plastic on soil during hot months for 4 to 6 weeks. The heat kills weed roots.
-
Targeted Herbicides: Use non-selective herbicides like glyphosate for persistent invasives and spot-treat carefully to avoid harming desirable plants. Always follow label instructions.

Prevention: Apply mulch regularly to prevent new growth. Monitor the garden regularly and remove new emerged weeds quickly before they spread.
