You Will Need
- 10cm pots
- Multi-purpose, peat-free compost
- Watering can with rose attachment
- Hardy annual seed
- Vermiculite (optional)
In March or April, fill your 10cm pots to the top with seed-sowing or sieved multi-purpose compost. Gently tamp the compost down in the pot and then level off with a pencil or stick.
Use your hands to sprinkle compost or vermiculite carefully over the top of the seeds so they’re covered to a depth of about 3mm. Label your pots.
Use a can with a fine rose to water the seeds in. Place in a greenhouse or on a warm, bright windowsill indoors. Keep the compost just moist.
When the first true leaves show, use a pencil to prick out each new seedling, holding it by the leaves, and planting out into individual pots.
Grow on indoors until after the last frosts (in May or June), when you can plant them out into your patch. If slugs and snails are a problem in your garden then wait until the plants are large enough to withstand attack, before planting out.
