my turnip/rape plot from last year just got a load of horse manure dumped on it and spread with my atv/bedspring. I have a bag of the evolved harvest throw and grow that I won at a gun bash last year. I think I am going to seed it and give it a try. What should i except. Bag says it contains tetraploid annual ryegrass, Rangiora Rape and berseem clover. Bag says it can be planted in the spring. I am concerned about the rape dying out in the hot summer. Don't know anything about the tetraploid ryegrass either.
