Petunia Trumpet Rainbow Mixed

When to Sow Trumpet Rainbow Petunia Seeds

January to March.

Where to Sow

Sow 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 polythene bag and keep an even temperature of 20-25°C until after germination which takes approx 7-21 days.

What to do Next

DO NOT exclude light as this will effect germination. When the seedlings are large enough to handle, prick off into trays 5cm apart. Grow on and gradually harden off for planting in the flowering site from late May 10cm apart.

Maturity

Late June onwards.

Handy Tip

The compact bushy habit of this variety makes it ideal for use in window boxes and patio containers.
