Method 4) How to Sow in Seed Trays

When growing large numbers of seeds of medium size (0.5-2mm), seed trays are useful, but I rarely use a full-sized one. A half sized one, as I’m using here, will produce plenty of seedlings.

Step 1) Fill your seed tray with Seed & cuttings compost, or put multipurpose in the bottom, and half an inch of seed compost sieved over the top (both ways will work).

Step 2) Gently tap the base of the seed tray on the surface of the bench to settle the compost. Press gently if necessary to level it.

Step 3) Sow your seeds – these are delphiniums – evenly spaced about half an inch (1cm) apart across the surface.

Step 4) Sieve a light covering of seed & cuttings compost evenly over the surface to just cover the seeds.

Step 8) Put the seed tray in a heated propagator as I’ve done here, or in an unheated propagator tray with a clear lid, or a clear plastic bag and place on a bright, warm windowsill
