Portulaca Growing Guide
Crop Rotation Group
Any fertile soil with good drainage.
None. Portulaca is a warm-season flower.
Mix a light application of a balanced organic fertiliser into the soil prior to planting. In early summer, drench plants with a liquid feed to support strong growth.
Portulaca flowers open during the day, so plant them where they can be seen during midday hours. The low-growing plants are excellent for edging beds or slipping into outer corners. In containers, combine portulaca with taller flowers that like full sun.
Single Plants: 20cm (7") each way (minimum)
Rows: 20cm (7") with 20cm (7") row gap (minimum)
Sow and Plant
Start seeds indoors in spring and set out the seedlings after the last frost has passed and the soil is warm. Many gardeners save time by buying portulacas as bedding plants.
Our Garden Planner can produce a personalised calendar of when to sow, plant and harvest for your area.
Portulaca tolerates blazing sun and the delicate blossoms attract honeybees. Colours include red, orange, violet, white and pink. In areas with long summers, portulaca often reseeds itself with seedlings appearing in early summer.
Pinch back plants every few weeks to stimulate the growth of new bud-bearing branches.
Excessive rain can cause portulaca to develop root rot problems.
