Seed Sowing
As spring arrives us gardeners start to get ready for the coming season and a major part of this preparation is seed sowing. Sowing seeds and nurturing them through germination into strong healthy plants is without a doubt one of the most rewarding tasks in gardening. Watching nature work its magic is something that I never tire of seeing. Wherever you sow your seed, be it on a kitchen windowsill, in a greenhouse or garden shed, following a few basic rules will aid your chance of success. Foremost is hygiene, have a good spring clean before sowing. All pots and trays should be scrubbed clean with biodegradable detergent. Staging, worktops and the interior of the greenhouse can also be done at the same time.
Now a decision has to be made as to which growing medium is to be used. There is a variety of seed composts available on the market but in general any medium that is not overly heavy, water retentive or high in nutritional value will suffice, personally I use coir and vermiculite. Coir is a by-product from coconuts, making it a renewable organic resource. The only downside to coir is the air miles involved in bringing it to this country although storage and transportation are easier now as it comes in dehydrated blocks slightly larger than a brick. When you are ready to use it place your coir brick in a tub, pour on the required amount of water and within ten minutes you have 10 litres of hydrated coir. Into this I mix vermiculite to help with moisture retention.
A seed has enough resources within it to germinate and grow up to the two-leaf stage. Warmth and moisture are the keys to unlocking these resources; some seeds also need light (e.g. primroses). All seeds have different germination temperatures, most will germinate between 15
