So I did something a little different because it worked with my kindsoil the first go round with the super soils. I mixed it up full strength and planted in a full pot of full strength no top layer of plain. I was doing the "plug@ method that
@Fairlynew or
@Eyes on Fire uses but I ditched the solo cup and just dug out a small handful and put the plain roots in. But I forgot to do it on a few of them and so they just went into the full strength pots and they all did great so I am goin for it ok these. Mainly cause it is easier lol my grape crinkles are using your soil amendment on the old kindsoil and roots that I am reusing. And they are loving it.
I will keep you posted and let you know if it still keeps working like this.
