SEED SOWING ADVICE: QUICK & EASY
Sow indoors at any time / or scatter directly in the garden in spring & autumn.
INDOORS: Sow seed in punnets on surface of good quality seed raising mix.
Then gently press the seeds onto the surface of the mix, to ensure good contact.
Now barely cover seed, because light is needed for germination.
And you can use sieved mix, or fine grit, or vermiculite, or washed sand to sprinkle over the seeds.
Then thoroughly moisten the mix from below – by placing the sown punnet into a water bath (make sure the water level in the bath is below the surface of the mix).
So the moisture percolates up through the mix from the bottom.
Soak for a short time until moisture appears on the surface of the mix, and then remove and drain.
Because the mix needs to be moist throughout, but not wet.
Then place the moist punnet in a warm, well-lit position (not in direct sun).
Temperatures of 15-20°C approx. are best for rapid and optimum germination.
You can use a temperature-controlled heat mat, if you have one, for rapid germination, but it is not essential. A window-sill or well-lit corner is also fine.
Seeds emerge 18-21 days approx.
If shy to germinate-seeds need a period of chilling in the moist mix to break dormancy.
So wrap the moist punnet in cling wrap (or a plastic bag) & place in the fridge (not freezer) for 4-6 weeks.
Then remove from fridge, unwrap & return to a well-lit position at 15-20°C approx.
Seedlings emerge in approx. 18-21 days.
