Before you can even think about planting some vines, you first need to look at the physical and chemical properties of the soil you plan on planting in. This is done by sampling the soil in different layers and sending these individual samples to a soil laboratory. When we receive the results we interpret the report and give a recommendation how to rectify the imbalances. Typically in the area I was in this morning the soils will tend to be more acidic. The soils are mainly that of withered Granite soils.
We mostly look at the Calcium to Magnesium ratio, the amount of Phosphorus, the acidity and some other micro nutrients. We can slightly adjust the micro nutrients before we plant, but it is easier and more effective to make yearly corrections in growing season with foliar sprays. The best way to get your micro nutrients back into your soil is with a good organic mulch.
