Once saw a YouTube video on cover crops
Can't find it again
But he threw all his veg seeds in the drill hopper .
All mixed up .
I in 5 acres he had normal cover plus the veggies
The town was welcome to harvest
You had to knock down the 3 ft high cover go find
Cucumbers , tomatoes, squash, pumpkin .....
It proves there are no weeds
Just competition for different root zones each a compliment to each other
At the end he let his cows in . They loved it
