How can I kill purslane?
You can eliminate purslane (Portulaca) with a thick mulch, with a hoe, or by hand-pulling. Purslane grows quickly in warm weather. Mulch that's 2-3 inches deep keeps the soil below cooler and prevents the tiny purslane seeds from pushing up through it. Whether you dig or pull it, remove it from the garden, because purslane forms new roots as it lies on the soil. Because purslane is a succulent, it can take a long time for the severed plants to dry up. In the meantime, new roots develop and the plants begin to grow again. You might also try developing a taste for purslane. It is edible and can be added to salads. Perhaps you'll like it so much that you'll soon be asking how to grow more of it!
