Trees and self-locking


Question: trees and self-locking


good morning, we are redoing the garden with the self-locking devices, could you help me to understand which trees or plants I could put without the risk of the roots raising them?
I like trees with a trunk, not shrubs, preferably that bloom and are not poisonous and I live in the Po valley.
Thank you

Answer: trees and self-locking


Dear Annalisa,
the self-locking units are tiles specially constructed to make them remain very superficial, they do not have large “foundations”, and therefore because the root system of a tree goes to remove them, it should have decidedly superficial roots, which run almost outside of the soil surface. So, with the exception of some particular coniferous trees, or some plants like yuccas, in theory you should have no problems with anything; however, the choice of a tree to place in the garden depends on a series of data. First of all, the exposure and the size of your garden: small trees can easily reach 4-6 meters in height; large trees reach 15625 meters in height. And the crowns of these trees are more or less as broad, as is their height. So, in addition to having a good exposure, you also need a lot of space. If the garden is small, consider the possibility of planting a single small tree, such as the catalpa: it is a sapling with roundish foliage, which produces a beautiful spring bloom, and a dense shade in summer, thanks to the its heart-shaped leaves; around the catalpa you will be able to put home some shrubs, which you can easily find in the nursery cultivated with the sapling, such as the Lagerstroemia (a beautiful summer bloom), viburnum of various species and varieties, ligustri, boxwood, roses; now almost all the plants are planted with saplings, even some varieties of solanum and lantana, for a cheerful summer garden full of color, even the cercis is a beautiful garden tree, with bright pink flowers in spring. In a small garden you can also plant fruit trees, considering that a plum usually does not exceed 3-4 meters in height, and begins to bear fruit already when it is about five feet high. Until a few decades ago, in the small gardens, stellar magnolias or tamarisks were widely used as ornamental trees: a beautiful flowering, and a small or medium-sized tree; unfortunately in the nursery it is difficult today to find these tree and not shrub plants, but you can always ask your trusted nurseryman. If, on the other hand, you have a beautiful large garden, then the choice of the tree to be planted depends totally on your tastes: maple trees of a thousand varieties, liquidambar, a small Albizzia with spectacular summer flowers, birch trees, a small hornbeam or a small elm, a liriodendron tulipifera, with large flowers similar to tulips. There are so many trees that can be cultivated in the Po Valley, take a tour of the nursery.
