Sow Gypsophila seeds on the surface of the compost in spring. Make sure that the compost is moist but not wet and seal in a polythene bag until after germination which usually takes ten to twenty one days. Do not exclude light which is beneficial to germination. Transplant when large enough to handle and grow on in cooler conditions. Later plant out in a sheltered spot. Plant out at about a foot apart. They may need staking against the wind if in an exposed position.
I have tried to grow these beautiful, herbaceous perennials before without success. This will be my year with them. These seedlings grow a deep tap root so need starting in a deep pot. They prefer not to be disturbed though. In March I may sow some seeds directly into the white border.
26th January 2017 about thirty tiny seeds sprinkled onto moist compost in a pint pot and enclosed in a polythene bag. All my seed pots are in the computer room and I try to keep the light on during these short Winter days. It is -4 outside this morning. 30th January and it looks like 100% germination already after only 4 days. I have taken them out of the polythene bag and moved them to the window ledge for light,
Well done Higgledy, 1000 seeds for £1.95 and 100% germination. I can’t wait for them to mature. Twelve weeks from germination I believe.
