Apricot and fir roots


Question: Apricot and fir roots

I would like to know how the roots of apricot and fir trees develop and how deep they can go. I inform you that the thickness of the ground is 70cm and below this there are garages. Hello and thanks.


Answer: Apricot and fir roots

Dear Walter, thank you for contacting us and for writing in the "Questions and answers" section. The two plants in question, apricot and fir, are plants with a superficial root system. The roots of these two plants develop in a maximum of 40-60 centimeters of soil and do not reach the deeper layers of the soil. The root system of these two plants thus develops on the surface, expanding a lot in width and a little in depth. One of the main problems of plants such as spruce, equipped with an apparatus that develops superficially and therefore not anchored very well to the ground, is the possible uprooting or crash. As can also be seen in the woods and forests, the spruce is often subject to wind crashes, that is, it is uprooted by high-powered winds that sometimes blow in many areas of our country. In an urban environment, in which buildings, roads and sidewalks hinder and force lateral root growth, plants with a superficial root system are more prone to wind crashes, because a large growth of the canopy does not correspond to an equally impressive growth. radical. The plant therefore undergoes considerable imbalances and the forces and weights that weigh on the hypogeal part, that is, on the roots, become unsustainable and at the first gust of wind of a certain force the plant can fall and cause serious damage to things, to people and the surrounding infrastructures. Furthermore, a second problem of plants that develop a superficial apparatus is that they often raise asphalt, cobblestones, avenues and all the infrastructures they find in their path. The force and pressure that a root can develop is truly impressive and in the case of superficial root systems, unpleasant problems and damage to the structures adjacent to the plant can occur over time.




Apricot tree: Tips for planting, pruning and maintenance

Apricot trees, native to Asia Minor, love heat, tolerate drought and fear wetlands.
They form small trees with a rounded tip that widen over time, reaching 6/8 m in height in adulthood. The white, early flowering (towards the end of February / beginning of March) fears late frosts: the flowers die at -2 ° C.

In cold areas, it is essential to plant them in a sunny and sheltered position. The fruits ripen depending on the variety from late June to August. They thrive in any type of soil, even calcareous, except those that are too humid or clayey. The trees are sold bare-rooted from October to April, in the form of mini stems or half stems. Fructification occurs in the 2/3 years after planting.

The varieties are self-fertile and do not need the proximity of other apricot varieties.
Bergeron it is the best known variety, its large orange fruits with firm and fragrant pulp, very sugary, are ripe in late July and early August.
Polonais it is an excellent late variety, towards the end of July, with melting and fragrant fruits.
Golden Aprigold it is a dwarf variety that does not exceed 1.50m in height and width, particularly suitable for small gardens, and in pots on balconies and terraces the amber yellow fruits ripen in July.


Spruce cutting: what is the probability of success?

Giovanni di Riese pius X (TV) asks:

Yes, yes, I remember the question well.
Well, it seems to me that you did things correctly, rooting times in conifers are very longmonths even in suitable structures such as those in the nursery, therefore I wouldn't expect roots until late April if not May and yes, the percentage seems reasonable to me.
Let me know.
