Growing flowers, fruit and vegetables from seed is easy if you follow a few simple rules. We show you how in this simple guide.
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 3) Shake some of the seeds out of their packet onto the palm of your hand.
Step 4) Carefully drop one seed into the depression in the compost surface of each cell
Step 5) Now sieve a light sprinkling of compost over the cells to cover the seeds
Step 6) Gently firm the compost down with the palm of your hand – don’t press too hard.
Step 7) Write a label including what you’re sowing, the variety and date of sowing, and stick it in the compost.
Step 8) Place the cell tray in a watering tray with 1in (2.5cm) of tap water in the bottom, and leave it to soak up 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.
