1. Pick a container:

Use small pots or seed trays with drainage holes. 

2. Choose the right Multipurpose Compost:

The label MUST state “for seeds” – do not use a generic MPC – (see why at our full ‘which compost FAQ’).

3. If you want to make you own Seed Growing Medium, mix together:

Use small pots or seed trays with drainage holes. 

• 2 parts fine-sieved Multipurpose Compost 
• 1 part perlite or fine sand 
• 1 part mature home compost 

This blend drains well, holds just enough water, and avoids nutrient shock. 

4. Plant the Seeds:

• Check the seed packet for depth instructions. A good general rule is to plant the seeds about twice as deep as their size. 
• For very tiny seeds, press them gently onto the soil surface. 

5. Gently water:

Keep the soil moist but not soggy. A spray bottle or fine watering can is ideal.

6. Place in warmth good light :

• Place containers on a sunny windowsill or under grow lights. 
• Most seeds germinate best at room temperature or slightly warmer. 

7. Feed later, not sooner:

Once seedlings have true leaves, replant (move) them into a richer mix. For replanting you can more to a general purpose MPC or mix your own: 

A. Richer Mix – Mix together: 

• 2 parts Multipurpose Compost 
• 1 part Compost 
• 1 part Perlite or Vermiculite 
• Optional – A handful of worm castings (for a natural nutrient boost) 

B. Lightly water – the seedlings in their current container about an hour before moving them. 

C. Fill small pots or trays – with your richer compost mix.

D. Firm it down lightly – and make a small hole in the centre with your finger, pencil, or dibber.

E. Use a pencil, plant label, or teaspoon to gently lever each seedling out – from underneath. Always hold seedlings by their leaves, never the stem (stems bruise easily and won’t recover).

F. Place the seedling into the hole you made – ensuring roots are spread out and not bent upwards. Firm the compost gently around the roots so the plant stands upright.

G. Give the seedlings a gentle watering – to settle the compost around the roots. Keep them out of direct strong sun for a day or two to recover.

H. Aftercare – Keep the compost moist but not soggy. Once they’re established, you can start light liquid feeding if they’ll be in pots for several weeks before planting out. 

8. Move into larger pots when ready:
