Rosebay Willowherb

I shall try again and maybe try various germination regimes ( i.e. wet/dryish, light/no light, cold soak or raised temperature in a polythene bag etc. That ought to cover the options. It is concievable that all you need to do is water them with some wood ash and water. Various South Africa semi-desert plants have specific germination inhibitors that require passage of fire followed by rain before they will let the seeds germinate. Ensures little or no competition for the seedlings after a bushfire has cleared an area. Not heard of it for rosebay willow herb before, but I guess it is possible. Many of the successful weeds have very long lived seeds with extremely erratic germination so they can opportunistically germinate when coditions are right. Poppies on newly disturbed earth is a classic case. Regards, Martin Brown |
