SEED SOWING ADVICE: QUICK & EASY
Sow all year in punnets indoors / or scatter in the garden in spring or 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 / fine grit / vermiculite / 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 right 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 punnet moist in a warm, well-lit position (not in 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. A window-sill or well-lit corner is also fine.
Adding a clear plastic cover helps to retain 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.
