I had a conversation with a friend today about sowing seeds, and I realised, not everybody actually knows how to go about doing it.
March being the time of year to get seriously planting, I figured I’d do a very quick overview of seed sowing. First things first, always – and I mean always – read the information on the back of your seed packet. Read it properly. This should give you details about when to sow your seeds and where. Usually it will have a little calendar on it too with information about when to plant, transplant and harvest. It will also usually give you information about sun position and soil drainage that the plant requires so pay attention to these.
Quite a lot of plants, vegetables in particular, are very sensitive to being transplanted and need to be planted directly where they are to grow. To do this, first ensure your soil has been treated well, manured during the winter if necessary. You’ll need to make sure there aren’t too many stones or large pieces of rubble in your soil. This is where a rake becomes a gardeners most valuable tool (controversial? I’ve had a few arguments with people about this one). Use your rake to remove debris from the soil and create what is known as a fine tilth. Mark off your drills, I usually just use bamboo canes and twine. Use a hoe or a piece of bamboo to create a shallow drill for your seeds, then lightly firm the soil down when they are covered. Then of course, water them in.
Now, to start, I would suggest a good seed compost or vegetable growing compost, these will contain the vital nutrients for germinating seeds. Do not use cheap, poor quality compost as your seedlings will suffer. When transplanting on, you can then use potting compost etc.
Some seeds require heat to germinate. I use a heated propagator for these, it simply plugs in and keeps your soil at a constant temperature, usually between about 19-22 degrees celcius. They usually have vents too for beginning to harden off your seedlings before potting them on. Otherwise, for indoor planting, I would suggest placing your pots and propagators on a sunny windowsill as seeds also need light to germinate.
When planting seeds in seed trays/pots, fill the tray to the top with compost, don’t skimp as it will sink when you water them. For some plants, it helps to put some fine gravel in the end of the tray for drainage. I always bang the tray on the surface of my potting bench a few times to level the soil out, then I use a piece of wood or a ruler to scrape away any access and create an even seed bed. Plant the seeds at the depth suggested on the pack. When you have the seeds planted, always water them in gently. What I do is poke small holes in the lid of a drinking water bottle and use that to water my seeds, it works as a mini watering can and it’s easier to control. be sure not to drown your seedlings, this leads to what is known as “damping off”, which is a disease caused by soil borne fungi when growing conditions are too wet and seedlings don’t have adequate ventilation.
Then, cover them if necessary with a plastic lid or bag. Don’t forget to label your seeds, it’s very easy to get them mixed up when you have trays and trays and pots and pots of seeds scattered everywhere.
Oh, and just in relation to my comment above about my rake. I’d be interested to know just what tool is your most valued in the garden, I’ve popped a little poll below.
As always, I’d love your feedback, or suggestions for my next “How To…” post
