How to grow perennials from seed<\/h2>\n- Most hardy perennials can be sown in early spring, under cover in modules or seed trays at a constant temperature of around 18-20\u00b0C \u2013 a heated propagator<\/a> helps to ensure a steady temperature.<\/li>\n
- Once the seedlings have germinated (this can take anything from a couple of weeks to a couple of months, depending on the plant), remove them from the propagator and place on a sunny windowsill or in a greenhouse<\/a>.<\/li>\n
- Once they have produced true leaves, prick them out.<\/li>\n
- As they grow, pot the seedlings on into larger pots.<\/li>\n
- Harden off before planting out in late spring or early summer.<\/li>\n
- Alternatively, you could scatter the seed where you want it to grow in late summer or autumn, when most plants are naturally producing seed.<\/li>\n<\/ul>
