- Water with fine mist spray to avoid disturbance of the seed.
- Place in a warm shaded or semi shaded position to avoid dying out.
- Keep warm & moist, avoid drying out or waterlogging the growing mix.Germination generally occurs in around 10-60 days at 18-22°C
- Place the seed tray in a warm place in the shade.Check the seed tray regularly and add moisture if it looks like it is drying out but do not waterlogg the container.
