Sow: into plug trays ideally to prevent root disturbance, or seedling trays. Germination takes around 7 days at 17-20o
C, when sown onto an open seed-sowing compost, and covered lightly with vermiculite.
Light is not necessary for germination. Temperatures above 21 oC will reduce germination, so in Summer choose a cool location away from direct sunlight, better still use a temperature - and humidity-controlled germination room.
Control water levels; too wet and the young seedlings will stretch. Start moderate liquid feeding the plug plants after 2-3 weeks. Grow on at 17 oC maximum to avoid stretching of the young plants.
After 5-6 weeks the young plants are ready for transfer into 6- or 9-packs, or 8cm pots, or else can be used for baskets and containers. As soon as the roots are visible at the bottom of the container, it is advisable to move Summer-raised plants outside, to avoid stretching of the plants. Stand them on a clean surface e.g. new woven plastic, to avoid picking up persistent diseases such as Theilaviopsis. Maintain a liquid feed programme.
