What you need to know to Plant & Grow
Double Mixed Portulaca is simple to establish indoors, requiring warm germinating conditions before transplanting out into full sun.
-
Indoor Sowing (Recommended): For a jump on the season, start seeds indoors in a sterile soil-less mix 6 to 8 weeks before transplanting outside in late May. Surface sow seeds directly on top of the medium—leave uncovered, as light is required for germination.
-
Germination & Growing On: Apply bottom heat and maintain a warm temperature of 26°C throughout the 7 to 14 day germination period. Once germinated, grow seedlings on under lights at a cooler temperature of 18°C.
-
Transplanting & Outdoor Site: Harden off seedlings carefully and transplant outdoors in late May once spring frost risks have passed. Choose a fully sunny site with light, well-draining soil.
-
Container & Garden Care: Portulaca excels in patio containers, hanging baskets, rockeries, and garden borders. Water only when the soil is completely dry to the touch, as over-watering reduces plant vigour. Fertilize regularly with a balanced plant food to maintain continuous bloom production throughout the summer heat.
