Method 3) How to Sow Seeds in Cells

Cell trays are good for larger seeds (2mm and bigger), sowing them one per cell. It’s best to use multipurpose compost, which is more fibrous and clings to the rootball, making potting up later on easier.

Step 1) Put compost through a coarse sieve to remove large lumps, and loosely fill all of the cells. Tap the tray lightly on the bench to settle compost.

Step 2) With your finger, dib shallow depressions in the surface of each cell. This is necessary for smaller seeds like the calendula I’m sowing – you can just push bigger seeds into the compost.

Step 9) Put the cell tray into a heated propagator, or in an unheated propagator tray (lined with newspaper to stop drips) with a clear plastic cover over the top, as I’m doing.

Step 10) Put the tray in a bright, warm position – mine’s in the greenhouse, but a warm windowsill indoors would be fine.
