My mother-in-law had the brilliant idea of planting, about 15 years ago, two spruce trees used for the Christmas tree, and two palm trees, on the roadside and close to the fence in a flowerbed about 60-70 cm wide. Is their expansion possible? What is the best time? what are the techniques? Thanks so much
Dear Antonella, welcome to the section of our website dedicated to readers' questions. Even if fir trees are beautiful trees, especially if in their natural environment, from the mountain level to the subalpine level, in the city and near the houses they can actually create thoughts and problems.
In fact, their root system develops on the surface and in an environment such as the urban one, in which sidewalks, roads and flowerbeds are continuously excavated, arranged and excavated, the stability of plants such as Picea abies can be seriously compromised. A plant like this, in fact, despite appearing large and thick, is actually supported on subtle balances given by the complexity of the roots which together collaborate to balance and counterbalance the internal and external forces that act on the plant itself. Going to remove even a small part of these roots, which often happens accidentally during excavations and works of arrangement of roads and or houses, there is therefore the serious risk of compromising the stability of the spruce plant, increasing the probability that it falls with the arrival of a little strong wind or other atmospheric agents.
Plants such as spruce, when placed close to a fence near the roadside, therefore become potential causes of damage to objects and people. Removing a 15-year-old spruce is not a simple thing; if on the one hand the superficial root system reduces the depth to which the excavation must reach and therefore could partly simplify the operations, on the other hand the so small size of the flowerbed suggests that the roots of the plant have long since boundless and it is therefore necessary to make an excavation much larger than the size of the flowerbed in order not to damage roots and rootlets and therefore have a greater probability of taking root.
The best period for the removal of this species is during the vegetative rest as soon as the intense cold is over in order to avoid the risk of frost. However, explant is a very delicate operation which presents a good percentage of failure risk; the greater the age of the tree, the greater the probability and the risk that the removal will not be successful.
These large trees are widespread in the Alps but there are also spruce forests in northern Europe and North America.
They do not have great climatic preferences and are able to tolerate both high temperatures and more rigid ones well, they love to receive direct sunlight throughout the year. Young individuals could suffer damage from winter frosts so it would be best to shelter them from them.
They live very well in acid soils, but if they are to be grown in pots it is advisable to create a mixture of peat, sand and clay to facilitate water drainage and create the conditions most congenial to them.
Generally it does not require pruning but can be performed to give greater consistency and a more regular shape to the crown.
unfortunately the palm has been damaged because the roots have been exposed for too long.
It should check if the center of the branches is still green or not. In case it was green the Kentia, this is the name of the plant, it should be resumed.
In the event that it is a tree in a garden of the condominium, the felling can be approved by the assembly by a majority of those present in addition to a third of the thousandths, in second call (instead "innovation" is configured only the felling plurality of trees of great value that depreciate the decorum of the building, for which the majority of participants in the condominium and 2/3 of the value of the building are required). L'killing of trees it is an act of extraordinary maintenance. The related expense must be divided by thousandths of ownership.
Maria Grazia of Bologna asks:
Hello very kind Mrs. Maria Grazia.
As for the products you have seen on the internet, I tell you that it is substances with curative action which, once inserted into the stem by injection or cannula, are able to enter the lymph of plants through the apparatus vascular xylem and phloem, going to hit the parasite at the point of attack or infestation where it is active. So for all intents and purposes they are curative products.
The plant protection product more suitable for the fight against the red weevil of the palms is based on abamectin, classified as harmful and dangerous for the environment, of biological origin, with acaricidal insecticidal action, translaminar activity, which acts by counting and ingestion.
For palms, the application is prescribed, starting from the first flights of adults, in endotherapy through trunk injections, located near the apical areas of the palm, in the ratio of 50-100 ml / hl of water.
It is good practice to have one well hydrated plant, or provide irrigation to promote water flows and the consequent translocation inside the palm. If the plant is not completely compromised by the attack of the red weevil, it is worth trying this strategy in order to eliminate the parasite where it is present. If, on the other hand, the plant is totally compromised, it is better to cut it down and the remaining residues to be burned in order to eliminate a probable source of infestation.
Thanking you for your question, I cordially greet you.
