Growing Herbs From Seed

Sowing Plugs

1. Trays come in a range of sizes from four large plugs to many hundreds of small 1/2 in (1 cm) squares and are ideal for sowing seeds where you only need one or two plants to grow in each module (Image 1).

2. So you don't lose track of where you are, sow larger seeds on the surface of all the modules and then press them down to the correct depth before covering in one go (Image 2).

3. Pinch out excess seedlings, leaving the strongest with plenty of space to grow on (Image 3). Transplant into a larger container or plant out when the plug is well filled with roots.
