This past weekend was our "Seedy Saturday" and I got my hands on some Cyperus esculentus tubers, also known as nutsedge, chufa nut and ground almond. It is a type of sedge which has been used for millenia for its tasty, oil rich centimetre long tubers.
In tropical or warm temperate climates these tubers grow back into plants every year. I've not seen anything that would make me believe this would be true for me, but in doing more research I discovered that wild turkeys go absolutely crazy when they find it; ripping the soil apart to find every last nut which may be as much as a foot deep.
For the last 3 years I've been in the process of transforming a 20 year old, approx. 3 acre forest meadow into a savanna. The soil is surprisingly poor, mineral and full of stones and rocks -- very difficult to loosen up, plant
trees or just to bury
wood. Every time I've been dealing with an area so far I've been using sheet mulching techniques, which has worked well but I'm afraid getting tilth this way is going to take a long time.
So, this is my idea. I will start the plants in pots early, plant them out into the area I want to upgrade next on 1 foot centres and let them grow for the season. I read in one place that in nitrogen poor soils they produce more tubers. Then in the fall, I'll just turn over as many plants as I need, to gather for myself and for the next years plantings. Leaving some nuts exposed on the surface will show the turkeys (new in this area in the just last decade) where the goodies are to be found, and then stand back while the dirt and the feathers fly.
Hopefully in the spring I'll have a broken up area, easier to remove rocks, bury wood, incorporate biomass, and plant a new garden. (probably potatoes the first year). Anyway that's the plan.
