How to Get Rid of Purslane Weed?
Purslane weed can easily infest large areas, so it’s important to act quickly. If left to reach its seed stage, the plant will disperse its seeds and cause additional problems. The most effective method of eliminating purslane is by hand pulling the plant.
Generally, a single plant covers a large area, thus with a little bit of work you can quickly clear large sections of your garden.
Application of an herbicide on purslane can be helpful in removing this weed from your garden but is more effective when the plant is still young.
Also, any part of the stem or root left behind can produce new plants. So it’s important to remove all existing pieces or plant material of purslane before your new seeds have a chance to take hold.
Purslane, a resilient weed, can survive even after it is uprooted from the ground. Its seeds, which can remain viable for years, are easily re-distributed when thrown into the trash or compost pile. To ensure that all traces of Purslane have been removed from your garden and to prevent re-rooting, it is important to properly dispose of the weeds. Place the plants in a paper or plastic bag before throwing them away. With this method, it will not be able to establish itself in your garden again.
Purslane seeds need light to germinate. So a heavy layer of mulch or paper can be effective in preventing further growth.
Pre-emergent herbicides can also be used to keep the new seeds from germinating.
With these tips and strategies, eradicating Purslane from your garden is an easy and achievable job.
