Grapevine soil turned into a brick
I just recently planted my grapevines in a soil mixture of 2 bags top soil, one bag of green sand and half a bag of peat hummus. I planted them yesterday and when I went today to check them I noticed that the soil on top exposed to the sun turned into a hard crust almost as hard as a brick so I dug down and the soil below was soft but the top part is hard. Does anyone know if I just ruined my grapevine? I put peat hummus on top to act as a mulch to keep the bottom soil moist but I am worried if we have a hot summer that the soil will turn into a brick.
