In view of the plantation a new essence is needed first of all prepare the hole in the ground. This operation must be done a few weeks in advance of planting to allow the earth to settle and be obsessed. Then there are other tricks that favor good rooting, let's see them together.
Planting: the width of the hole
The rule says that the hole must be at least twice the size of the bread of earth to be planted. This means that a plant in a 20cm pot needs a hole at least 40cm wide, and so on (30-60, 40-80).
But be careful: the double rule must take common sense into account. For a tree that is already large enough with a clod of 1 meter in diameter, a hole of 2 meters is not needed because the root system is already sufficiently formed. Conversely, a very small fruit tree in an 18 cm pot will love a hole even 50 cm wide. In short, the width of the hole depends on the age of development and the type of essence in plantation, but it must always be 'abundant'.
Planting - the depth of the hole
How deep the hole must be is indicated by the collar of the plant to be planted. The point that marks the transition from the trondo to the roots (precisely the collar) must always be at ground level. To get the right size, hold the plant with one hand and with the other place a stick from one side of the hole to the other. If the collar protrudes from the ground level, remove soil; if the collar is lower, add soil under the roots.
Planting: the shape of the hole
Round, square or other shape. Recent studies state that plant roots develop earlier and better in a diamond-shaped hole. Don't ask me why (I believe that even those who made the discovery ignore the reason) but it seems to be so.
Planting: filling the hole
The earth removed from the hole must be accumulated on the side and chopped up well. If it is too compact, it should be lightened by adding sand or peat. If it is not very porous, it should be mixed with soil of leaves and compost (perhaps obtained from home composting) and if it is too loose and does not retain enough water. If, on the other hand, the ground tends to retain too much water, causing stagnation, it is useful to dig a hole a little deeper and put a layer of gravel, expanded clay or terracotta shards on the bottom. This drainage layer should be covered with 20-25 cm of earth before planting the new plant.
Planting: the finishing
Once the new plant has been planted, you need to press the soil around the collar with your feet, especially if the hole is large. Then you have to fill around by adding more earth, but leaving a shallow basin around the trunk. In this way, watering will be more effective.
