Seed Treatment Method

Cold Some species require exposure to cold before they germinate. These species are best sown in early winter and left to germinate in a shade house. , Bog Method The seeds of many wetland species need to be kept wet to germinate. Punch a hole in the side of a recycled polyfoam box so that it holds water to the required depth. Sit the tubes in the box to germinate. Once germinated, punch holes in the bottom of the box to allow drainage.

Seed Treatment Notes

Try using bog method. Seed may benefit from stratification at below 4°C for 3-6 weeks.
