Sow in small pots of about 5cm Ø 2 seeds per pot. Use some moist pottingsoil. Keep moist but not to wet to prevent the seeds from rotting. Put them on a very warm spot with a very constant temperature. Use a propagator with a warming mat and lid.
Remove the lid when the seedlings emerge. Transplant the seedlings, when they're large enough to handle to larger separate pots. Plant the seedlings outdoors from about the end of may on a very sunny, sheltered plot with some free draining soil and give them a sturdy support. Keep about 50 - 75 cm apart.
