Sowing seed in pots

Sowing seed in pots

  • Useful for plants with larger seeds
  • Sow more than one seed per pot
  • Select strongest seedling per pot
  • Can be started indoors
  • Biodegradeable pots can be planted in-tact

For sowing seed in plastic or biodegradable pots, the process is the same:

A range of seeds can be sown in late winter and early spring in anticipation of warmer weather. Sowing seeds indoors or in a greenhouse allows us to get a head-start so that we have seedlings ready to go out into the garden as soon as weather conditions and temperatures permit.  The sort of plants that benefit from this early start are a range of summer crops that have high yields but need a good run of sunny days to reach maturity – things like runner beans, cucumbers, melons and pumpkins. In cooler parts of the country sowing indoors is especially key in getting crops such as melons and pumpkins to ripen before summer is over.

Seeds are often sown in plastic pots for sale in nurseries. At home you can sow seeds into biodegradable pots, its an ideal way of getting healthy seedlings ready for their days outdoors and reducing the chance of delicate seedlings being damaged or suffering transplant shock when they are put out into garden soil or containers. Seedlings grown in plastic punnets or pots have to be carefully lifted out when they are planted, roots can easily be damaged at this stage and plants may grow stunted as a result. Seedlings grown in biodegradable pots made from peat, recycled toilet roll centres or made from newspaper can be put into the ground whilst still in their containers that quickly fall apart when surrounded by soil. Young roots are protected and can get away quickly without plants being stressed. 

How to sow seeds in a pot

Equipment: Pots, seed raising mix, seeds, watering can, label
TIP: Soaking seeds for an hour or so before sowing can help to stimulate germination.

1. Choose your pot – these are peat pots

2. Fill with seed raising mix.

3. Tap pots on side till seed raising mix settles

4. Place two or three seeds in each pot

5. Bury seeds at recommended depth

6. Label and water with rose attachment on watering can.

7. Place in a water-tight container

8. In colder months use a clear cover to retain moisture until seedlings appear – then remove.
