Yes, moss rose seeds germinate best when sown on the soil surface or covered only very lightly because light supports germination. Press the seeds gently onto moist, well-drained soil and keep them warm until seedlings appear.
Moss rose often begins flowering about 8–12 weeks after sowing, depending on the variety, sunlight, temperature, and growing conditions. Starting with healthy seedlings and providing full sun can support flowering during the warm season.
Moss rose thrives in hot, sunny weather and can grow in relatively poor, sandy soil as long as drainage is good. Avoid heavy, waterlogged soil and excessive watering, which can cause root problems and reduce plant performance.
