SEED SOWING ADVICE: QUICK & EASY
Suits beginners & gardening with kids
Sow all year in punnets indoors / or scatter in the garden in spring or autumn.
Sow indoors for quickest & early plants: First sow the seeds in a punnet on surface of good quality seed raising mix.
Then gently press the seeds onto the surface of the mix, to ensure good contact.
Now only barely cover seed, because this plant needs light for germination.
And you can use sieved mix / fine grit / fine vermiculite / or washed sand to sprinkle over the seeds.
Then thoroughly moisten the mix from below – by placing the sown punnet into a shallow water bath and allowing the moisture to percolate up to the surface of the mix from below.
Now drain and place the moist punnet in a warm, well-lit position (not in any direct sun).
Temperatures of 18-25°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, as these seeds are willing germinators.
A shaded window-sill or well-lit corner is also fine.
Adding a clear plastic cover or plastic bag helps to retain consistent moisture in the punnet.
And continue to keep the punnet moist by spraying the surface of the mix a fine spray water bottle, or re-soaking in the water bath, as required.
If the punnet is light weight when you pick it up – the mix is drying out and needs another soak from below in the water bath.
Seedlings emerge in approx. 14-28 days.
Seed Count: 150 seeds per pack approx.
(We always aim to exceed the stated seed count, and give a generous serve).
