SEED SOWING ADVICE:

Sow at any time of year in punnets indoors / or scatter in garden winter-early spring. Seeds need cold.

Sow indoors for quick plants: First sow the seeds in a punnets on the surface of good quality seed raising mix.
Now sprinkle lightly with sieved mix to the same diameter as the seed.

Then stand the punnet in a shallow water bath and allow the moisture to percolate up to the surface of the mix from below.

Now place the moist punnet in a warm, well lit position (but not in any direct sunlight).

Continue to keep the mix consistently moist by misting from a spray water bottle.
Covering the punnet with clear plastic lid or a plastic bag will help maintain consistent moisture.

Keep at 18-22C approx. for 2-4 weeks.
You can use a temperature controlled heat mat if you have one.

After 2-4 weeks of warmth, then cling wrap the moist punnet and place it in the fridge (not freezer) for 4-6 weeks.

Then unwrap & remove to an unheated, cool place. Heat is not required for this period, and may indeed slow germination.

Most seedlings emerge in 5-30 days.
But do not discard the punnet too quickly, as some seeds may come later.

Prick out as seedlings as soon as possible to larger pots, as the seedlings will grow strongly and form long tap roots quite quickly.

Seed Count: 10 seeds per pack approx.
(We always aim to exceed the seed count and give a generous serve).
