You can start off Chinese lanterns by sowing the seeds indoors first, do this at the start of spring. It should take about two to four weeks to germinate at 21 to 25 degrees centigrade in the light. Once growing transplant into the garden about 30 cm apart (small Physalis species) to 60 to 90 cm (larger varieties).
