Sow seeds to move into a cold frame later

Sow seeds in pots and place them in a cold frame later during spring to harden off before planting in their final position. By sowing seeds inside into trays or pots for later transplanting into the garden extends your garden season by getting you off to an early start. You can grow plants that that need extra warmth to germinate or a long growing season. Always use clean containers when planting. You can plant into seed trays or into individual pots. Seeds need to be able to push new roots out into the soil to gain the nutrients and moisture they need. Seed starting soils ideally should be friable, absorb moisture but let excess moisture drain away, and not compact. Sterile soil reduces the risk of disease, and mixes with fresh compost and organic matter may not be suitable for this reason. There are many commercial mixes available for starting seeds, or a regular potting compost may be suitable.Fill a container with seed mix and moisten. Sow seeds evenly in seed trays to encourage good growth. Crowded seeds will be leggy and compete for nutrients. Cover the seeds according to the instructions - some seeds germinate better without light, others prefer it. A glasshouse, greenhouse, conservatory or bright (but not scorching) windowsill is ideal for starting seeds. Make sure that you turn the seedlings regularly to encourage even growth and prevent leggy seedlings. Water gently and regularly to maintain moist but not wet soil. Lack of air circulation and over watering can lead to damping off, when the seeds collapse and die.
