Sedum: Sowing, planting and harvest calendar
How to sow sedum outdoors?
Check the sedum species named on the packet and follow its temperature and sowing-time instructions. Some seeds need a period of moist chilling: follow the packet's instructions. To monitor these fine seeds more easily, use a seed tray or small pots with drainage holes outdoors in a bright position sheltered from heavy rain.
Fill the containers with fine, well-drained seed compost and moisten it before sowing. Distribute the seeds as evenly as possible over the surface and press them gently into contact. Do not space individual seeds twenty or thirty centimetres apart. Surface sowing allows light to reach them, so avoid burying them under a layer of soil.
Keep the surface slightly moist during germination without saturating the growing medium. Water very gently to avoid moving the seeds. An adult plant's drought tolerance does not mean seedlings can dry out completely. Also avoid scorching sun that rapidly dries a small tray.
Once seedlings are large enough to handle, transplant them carefully into small pots. Protect young shoots from slugs and gradually accustom them to their final position. Set the eventual spacing according to the species or variety's mature size. Germination and growth may vary, so do not expect the same timetable for every sedum.
