“Kudzu was intentionally brought here by THE GOVERNMENT...........FDR, IIRC.........”
Funny story. I have some acreage but have a county road in front. I wanted to grow something that would screen the car lights from shining in our house at night (at least during the summer).
So, I purchased a bunch of kudzu seeds. The package said, “be careful! Kudzu will grow on cement, and it will get away from you very quickly!”
Perfect. So, I planted it with rich topsoil and fertilizer and watered frequently.
Nothing. So, I gave them away. The person I gave them to planted by sprinkling on top of hard, crusty ground. He has a problem now that I wiash I had.
Moral: kudzu doesn’t like it when you pamper it.
Some seeds won't germinate without air - such as tobacco. Bury it and it'll go no where. Spread on top and you got sprouts.
