While some gardeners battle purslane as an invasive weed that encroaches growing areas, others embrace this edible plant and grow it to use as a flavorful addition to salads and other fresh entrees. Grow purslane mix in an area where the succulent foliage will receive abundant sunshine and warmth. Stay vigilant as you grow purslane to ensure that it does not self-sow so energetically that it interferes with other nearby plants.
Prepare a sunny growing area in the spring when all threat of frost passes. Cultivate the soil to a depth of 3 or 4 inches and add 1 inch of compost over the top of the soil. Work the compost in well with a spade. Smooth the soil surface with a rake.
Saturate the soil with spray from a garden hose before planting the purslane seeds.
Place the purslane seeds on top of the soil, spacing them 1 to 2 inches apart. Do not cover the seeds with soil.
Thin the seedlings when they are approximately 3 inches high so the strongest seedlings remain about 5 inches apart in the growing area. Cut the weaker seedlings off at soil level with scissors.
Keep purslane evenly moist throughout the growing season, adding enough water to keep the soil from drying out.
Harvest purslane when the leaves grow at least 1 inch in length. Clip the leaves from the plant with scissors to allow the plant to continue to grow.
Control the spread of purslane by cutting the plants down before the flowers scatter seeds on the soil.
