What you need to know to Plant & Grow
Lavatera roots form extensive networks once established, so care should be taken to minimize root disturbance during transplanting, or seeds can be sown directly outdoors.
-
Direct Sowing (Recommended): Direct sow seeds outdoors in early to mid-May once soil is workable. Sow seeds 3 mm deep and water gently. Thin emerging seedlings to at least 30 cm apart to give the branching plants room to mature.
-
Indoor Starting: Start seeds indoors 6 weeks before your last expected spring frost date using individual peat pots or cell packs to lessen root shock during planting out.
-
Germination Conditions: Maintain a soil temperature of 21°C for the 7-day germination period.
-
Growing On & Transplanting: Once sprouted, grow seedlings under lights at a cooler temperature of 15°C. Harden off gradually and transplant outdoors in late May after frost danger has passed.
-
Continuous Blooms: Prefers full sun and excels in cooler weather. Because warm summer temperatures accelerate the blooming cycle, successive sowings every two weeks in spring will ensure a non-stop succession of fresh blossoms well into fall.
