How to Kill Oxalis Weeds

Oxalis weeds are the bane of existence for anyone who attempts to eradicate this bothersome plant life. There is actually no way to actually completely destroy this common and fast-spreading weed. However, depending on the circumstance in which oxalis weeds occur, there are ways to keep the weeds at bay.

Things You'll Need

• Weed killer
• Plastic bags
• Plastic
• Mulch

Instructions

1. Cover the flower bed with plastic, then soil and then mulch. The oxalis weed struggles in a lack of light. Therefore, smothering is one way to keep flower beds relatively oxalis free. Know that smothering is not an option for lawns or cement and paved areas and if you simply pull out the weeds, seeds are released immediately and within days, baby oxalis weeds will be popping up.

2. Cover an individual weed with a plastic bag and pull it (this takes patience). Then place the weed into another plastic bag or trash can immediately. If the weed is placed on the ground in a pile, from that spot there will undoubtedly be more oxalis weeds because the seeds are easily spread and each weed has no shortage of seeds.

3. Utilize weed killers in areas where other plant life will not be affected. Several weed killers boast about killing oxalis weeds (and not other types of plants). While they kill the weeds, they do not prevent further weeds from springing up. These weed killing sprays usually work, but the dead weeds must be removed in a similar manner to live weeds as the seeds can still be spread.

4. Remove the plant from any potted plants, discard all of the soil and hose off the plant (roots and all). This is done to get rid of any oxalis seeds that may be in the soil, the pot or on the plant. Then, the pot must be cleaned and the plant placed back into the pot with new soil.

Tips & Warnings

• Keeping oxalis weeds to a minimum is the only plausible solution.
