Ramps are TRICKY. Let's get that established from the get-go.
As we outline in the book, and in this previous blog post, (http://farmingthewoods.com/2013/04/18/ramps/
), there is potentially a lot of overharvesting going on for wild populations. So what are we to do?
Similar to ginseng, a good strategy is to divide ramps from a local stand and start a new patch in your forest. But not just any woods - ramps have a particular ecosystem type they like, and they probably won't do well outside of that range. The ideal site is; Sugar Maple woods, North or East facing slope, with plenty of moist soil rich in organic matter. You can stretch some of these qualities a bit, but probably won't have much luck say, on a South facing slope dominated by Oak.
Also critical is understanding the life cycle dynamics of this species. Our extension forest farming team put together a great series of videos on ramp culture: http://www.extension.org/pages/69588/youtube-channel-ramp-series
Seed is also potentially a good way to start ramps. Seeds take up to 18 months to germinate, so often people think it's not working, when really they need to give a patch more time. We've had the best success with both sowing seed and transplanting bulbs in the late summer/early fall. (NOW).
