One of life's pleasures at this time of year is getting
a jump on the
growing season by starting your own plants from seed indoors.

more light you can manage, the stockier and stronger your transplants
be. If your seedlings grow tall and flop over, it's a good indication
you need more light.
To get started, you'll need to assemble some containers,
some soil and of
course, the seeds. You can use anything at all for containers,
sterilize them first with a good cleaning, and make sure they

directly in the garden pot and all. I haven't had much luck with

For starting seeds, you should use a special mix of soil.
It's easiest to
buy it ready made, but you can make your own by mixing equal
screened topsoil (or compost), peat and coarse sand. After mixing,

until a thermometer registers 90 deg.C (195 deg.F). This should

weed seeds. You see why I advocate just going out and buying
fertilizer to bought or homemade mix. David Tarrant recommends
superphosphate at a rate of 15 mm (1 tablespoon) per pail of
soil to build
up strong root systems.
Loosely fill the pots right up to the rim with lightly
moistened soil mix.
Level off, then press down with the bottom of another pot to
firm the soil.
Refer to the seed packet for specific sowing instructions.
Don't sow too
closely. If your seed is very fine, you can mix it with fine
sand to help
you spread it more evenly. The packet will also tell you how
deep you need
to bury the seed. Some seeds need light to germinate, and some
darkness. If you are sowing seeds that you saved yourself, or

not to overdo
it like I always do.
Place the pots on a tray and cover with glass or plastic.

Some seeds that you should do well with are tomatoes, lettuce,
onions, asters, zinnias, cosmos, marigolds, snapdragons, impatiens
petunias. But by all means, experiment. This is your chance to
something a little different than what you'll find in the local
centres in a few months. This is also a great way to have plants
in vast quantities. Consider how many plants (and pots) you are
need as you dump handfuls of seed into your growing mix. If you
it, the extra plants are wonderful to have for trading, plant
sales and just
