How to grow from seed indoors

Growing your own plants from seed is an enjoyable & cost-effective way to grow lots of flowers or vegetables.  Don’t worry if you don’t have a greenhouse, your seedlings will happily grow on a bright windowsill until they are ready to go out in the garden.

Shopping list:

  • Seed trays with propagator lids 

  • Your choice of seeds 

  • Dobbies peat free seed compost 

  • Watering can with fine spray 

  • Plant labels 

  • Heated propagator (optional) 

  • Growhouse (optional) 

Step-by-step guide:

  • Fill a seed tray with peat free seed compost, firming gently for a level sowing surface. If you don’t have a seed tray, use a small plant pot instead. 

  • Use a watering can with a fine rose to dampen the soil surface before planting

  • Sprinkle your chosen seeds thinly and evenly across the surface of the compost, following the pack instructions, being careful not to sow too thickly. 

  • Lightly cover with a thin layer of compost, removing any lumps, and insert a label with the plant name as a reminder. 

  • Pop a clear seed tray lid over the top and stand in a warm greenhouse or on a bright windowsill. Remove the tray lid when the seedlings sprout, keeping the compost moist while they grow. 

  • Your seedlings will be ready to plant in individual pots once the first pair of true leaves open. Use a blunt stick to lift each seedling out of the tray, holding them gently by their leaves.
