Seed Information

Seed Treatment Method

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

Seed should be sown fresh.
