What are some tips for growing Portulaca flowers?

One tip for growing Portulaca flowers is to plant them in rock beds, according to GardenersNet.com. They also should not be planted until after the last frost has passed.

Portulaca flowers grow well in loose soil. They also thrive best in full sunny conditions. The soil should be left to dry completely in between watering. Adding a high phosphorus fertilizer also helps with growth. After the plants bloom, the dead heads should be pinched off. This promotes new growth. Since the plant is prone to harmful insects and fungi, insecticides and fungicides should be used as needed. The frequency and amount depend on the problem.
