Allelopathy--plants that keep your seeds from germinating

 
We've previously posted  our discovery that sweet potatoes planted in your garden act to deter subsequent crops from germinating or thriving. A recent post by UF/IFAS sheds further light on this.   In fact, I learned from the UF post that a recent cover crop in the VegHeadz garden--Sunn Hemp (Crotalaria judncea)--is one of those plants. We used Sunn Hemp as a cover crop in one of our plots last spring.  It will be interesting to see how this season's crops fare in that area.
