Sowing Guide

Early Sowing/Module Sowing

Sow coleus seeds on the surface of moist compost in pots, trays or modules.
Lightly firm the seeds into the surface of the compost. Do not cover the seeds.
Place the container in a propagator or if preferred in a clear polythene bag and seal. Do not exclude light as this will help the germination.
Once germination has started remove from the bag or propagator and move to a warm location with good daylight exposure however protect from full sun at this point.
When the young seedling's are large enough to handle transplant into 7 - 10 cm pots.
Grow on in a warm (room temperature), frost free location.
Plant out when all risk of frost has passed. Before planting out harden off over 7 - 10 days to acclimatize the young plants to the outdoor temperature.

Direct Sowing

For best results start the plants indoors.

Growing On

Water the newly planted coleus plants frequently until established.
Pinch out the growing shoots of the young plants, this will encourage a bushy habit.
Apply a high nitrogen fertiliser every 2 - 3 weeks in the growing season.
Water well in dry weather. Remove flowers as and when they appear to maintain the foliage colour. To overwinter, coleus should be kept at room temperature and watering should be reduced.


If grown indoors as a houseplants the seeds of coleus can be sown at any time of the year.
