The topsoil makes a difference
I have a friend whom I had to talk into learning to make a garden
He has a small garden this year that grows food in a garden that is based on contractor’s topsoil. And it grows nice vegetables, like better than mine. He has shared some with me.
My garden is not as good, mostly being my food grown is not as good. My topsoil is about the same as what the Cherokee Indians had in their time, though I have put in lime and fertilizer, but it is still not as good as his garden, and without the extra help I give my garden.
All gardens are not created equal.
