When to sow
When to Sow Prism Sunshine Petunia Seeds
January to early April.
Where to Sow
Sow sunshine prism seeds thinly into pots or seed trays on the surface of good free-draining seed compost and cover with a fine sprinkling of Vermiculite. Place pots in a propagator or cover pots with a pokythene bag and keep an even temperature of 20-25°C until after germination which takes approx 7-21 days.
DO NOT exclude light as this will effect the germination
What to do Next
As soon as seedlings are large enough to handle, thin out or prick off into trays spacing 5cm apart. Grow on and gradually harden off for planting outside after last frost.
May to late October.
Do not overfeed plants as this will encourage leaf growth at the expense of the flowers.
