When you prepare the soil, a very crucial aspect you should consider is making sure you are using the appropriate soil area for the kind of vegetable you are planting. It does not matter whether you plan to raise vegetables in a small plot of land or in a plant box. Proper soil preparation is a vital step. Soil can be classified as sandy or clay-like, with silt being a fine mixture of both sand and clay. The clay elements in sand help retain water longer as well as make the soil absorb water faster. The sandy elements in soil make the water flow through it easily and let the air in so that the roots can breathe.
The ideal balance in soil preparation is mixing the correct amount of clay, sand, and silt. The proper amount is 40% silt, 40% sand, and 20% clay. What you can do to test it is to scoop up soil and form it into a ball using your hand. It should not be too hard as to not crumble when you poke at it, but it should also be sticky enough that it remains in its shape even if you do not press it too hard with your hands.
It requires a lot of patience in growing your vegetable herb garden and so, you must find what works best for you, but the experience and fruits of your labor will be all worth it in the end.
