How to sow and grow Garden Petunia Stellaris Red

• Germination: 7–14 days at 22–25 °C

Fill your seed trays or pots with a good-quality seed-starting mix. Make sure the mix is moist but not soggy. Petunia seeds are small, so sprinkle them over the soil surface. Do not cover them with soil, as they need light to germinate. Lightly mist the seeds with water so they settle into the soil. Cover the containers with cling film or a clear plastic lid to create a mini-greenhouse effect. This helps retain moisture and warmth. Check the containers regularly to make sure the soil stays evenly moist but not soggy. Mist the surface if it starts to dry out. Petunia seeds usually germinate in 7-21 days, depending on temperature and seed quality. Once seedlings appear, remove the plastic cover. Petunia seedlings need bright, indirect light to grow well. Place them near a sunny window or provide artificial lighting with fluorescent grow lights.

Sow in January–March — the seeds are dust-fine; scatter them over moist compost and cover with a lid. Feed regularly with a fertiliser for flowering plants.
