Sow seeds at any time of year in punnets indoors / or scatter directly in the garden during winter-early spring. Seeds need a period of cold for best germination.

INDOORS: Sow the seeds in punnets on the surface of good quality seed raising mix.
Then press the seeds gently into the surface of the mix to ensure good contact.
Now barely cover the seeds with mix / grit / washed sand.

Now place the sown, moist punnet in a warm, well-lit spot.
Temperatures of 18-22°C are ideal for rapid and optimum germination.
So you can use a temperature-controlled heat mat if you have one to encourage rapid germination, but it is not essential. A window-sill or well-lit corner is also fine.

Seeds germinate in approx. 5-30 days.

However if the seeds are shy to germinate after 4 weeks. Then cling wrap the moist, sown punnet and place in fridge (not freezer) for 4-6 weeks.

Then remove, unwrap, re-moisten, and return the sown punnet to well-lit warm place.

Prick out as seedlings as soon as possible after germination, and move into deeper pots, as the young plants quickly form long tap roots (which of course helps them to forage for water in a dry climate).

SEED COUNT: 10 seeds per pack approx.
(We always aim to exceed the stated seed count, and give a generous serve).
