Advice about seed sowing. We give you the information to grow plants from seeds.

When sowing seed in trays or pots, the best results can normally be obtained by simply sprinkling the seed onto the surface of ready-watered compost. If the tray does not have a clear plastic cover, then cover the tray with a sheet of clear plastic or glass (careful of the edges) and wait for the seed to start germinating (sprouting). The glass sheet will reduce the amount of watering required, but check every day to ensure not drying out.

You don't have to be a professional to grow a crop of seedlings like this - but you
do have to give the care and attention required

As soon as the seed starts to germinate, then sprinkle a layer of Vermiculite over the sprouting seeds and water in. The vermiculite will anchor the seedlings into the compost and also provide a moist environment around the new small roots of the future plant!

With larger seeds - such as Lupins and sweet peas etc. The seeds can be given a layer of vermiculite straight after sowing - without waiting for the seeds to germinate.

Some seeds - verbena for instance - will germinate better if kept completely dark! So a black plastic sheet is the answer, or a sheet of plywood or similar. But do make sure the cover comes off as soon as the seed germinates, or the seedlings will become 'drawn' and spoil.

Other hints - light requirements - temperature - growing on
