Rob Dalby on propagating from seed

Rob describes a method of improving the success rate of growing liliums from seed to near 100%.
During a presentation by Martin Fidge on what he was currently doing in his garden, the subject of propagation from seed was raised. Rob Dalby stood and made an impromptu address to the meeting on his take on the subject.
He usually sows in ziplok plastic bags that have been filled with damp coconut fibre and vermiculite.
The seeds are added, the bag sealed and stored in the house where they are kept significantly warmer, and at a more constant temperature than if they had been outside.
Rob was finding that although the seeds germinated well, he was losing most of them during the transplant phase of the operation. Both the shoots and the roots had become too long, and were being broken off, or damaged in some way during he decided to make a significant change.
This year, he made a note on his computer calendar to check the seeds about 2 weeks after seeding. After the prescribed 2 week period was up, he checked, and was most impressed when he found that a significant number were already beginning to shoot!

He immediately shook the shooting seeds out and across the surface of a foam box that was part filled with propagating mix, and covered the seeds with a thin layer of propagating mix. His success rate suddenly climbed to near 100%.
Martin then suggested that it would be a good idea for the foam box to be placed inside a large plastic bag to keep the humidity level constant, and to reduce the risk of the surface layer drying out prior to the roots getting down far enough to stay in the damp zone.
