Arboriculture: practical advice

Trees in different types of containers or pots can be planted year-round, except when it freezes. When you buy a tree or palm in a pot, you must have completed at least one complete cycle of vegetation within the container. Sometimes it happens that they are sold without being properly rooted in the respective container.

Before planting any tree or shrub, it is essential to have an idea of ​​the volume it will require when it reaches its full development after years.

Near the house, plant small adult trees such as Prunus, Aligustre, Lilo, Laurel, etc. and some species of palm trees.

In a small garden, plant small trees, for example, fruit trees.

On the south facade of the house, place deciduous trees, so that in winter they do not create too much shade since they do not have leaves and in summer they protect from the sun.

In the garden, create a sunny area and another area in the shade. To create the shade you can use trees or pergola climbers.

Ornamental arboriculture: planting a tree

If you can, dig the pits one month before planting the trees and leave them like this, in the air. This will promote good ventilation. In the case of rains, if the pits are flooded for many days, it is a sign that the drainage is not good and it should be improved.

Be careful when drilling holes in case there are irrigation pipes, water, gas, electricity, etc.

Transplanting trees and shrubs

When a tree or shrub is removed from the ground for planting elsewhere, it suffers trauma that sometimes cannot be overcome. To help them there are two types of products, not well known to the hobbyist but mostly used by tree services. Such products are very useful when you want to ensure the maximum success of the transplantation. It’s about rooting hormones and antiperspirant substances in the proportion indicated for each commercial product. They help to grow new roots. They are particularly useful for evergreen species, for example, conifers.

Isolated trees

Trees with beautiful blooming or with colored leaves or with beautiful shapes are ideal to be placed as solitary specimens in the garden, perhaps on a small mound to make them stand out even more. Some examples are:

Acer negundo‘Aureovariegatum’
Acer negundo‘Flamingo’
Acer platanoides‘Crimsom king’
Olea europaea(an olive tree that is centenary, with an old trunk)
Chorisia speciosa(for climates without frost)
Delonix regia(for frost-free climates)


Conifers are trees that attract a lot of attention due to their strength in terms of shapes, textures, and colors. Almost all of them are evergreen. Examples: Fir, Cedar, Cypress, Pine, Sequoia. The following species could act as focal points:

– Abies (some Firs)
Araucaria araucana
Araucaria heterophylla
Cedrus atlantica(varieties)
Cedrus deodara(varieties)
Cupressus macrocarpa‘Gold Crest’

Tree-to-tree distance (urban arboriculture)

Do not plant them too close together because later there will be no solution. This is a very common mistake. You must know before if it is a small, medium, or large tree.

Tree damage

When ditches are dug, a pavement is built, the soil is compacted, the level of the soil is lowered, etc., and what is being caused is damage to the roots. Do not disturb the ground at the foot of the trees!

Tree longevity

If any tree in the list below at 20-25 years is badly damaged and dry, it is normal, it has reached the end of its life. The following are low-longevity trees:

– Acacias (Acacia)
– Albizia (Albizia julibrissin)
– Aligustres (Ligustrumspp.)
– Fotinia (Photinia serrulata)
– Peach Tree (Prunus persica)
– Medlar (Eriobotrya japonica)
– Papayo (Carica papaya)

Christmas trees

The Christmas trees that are usually sold are trees taken from the ground without roots, that is, “to use and throw away”. If you buy potted spruce, survival after staying in a house is difficult because they are subject to high heating temperatures, when they should be close to 0ºC. This causes them to lose their pins and they cannot stand the subsequent transplant. Still, you can try following these growing tips while your spruce is at home:

– Water every 3 days.

– Put it in a big pot with a drain hole at the bottom.

– Away from heating radiators or stoves.

– Wet the leaves with a spray.

– If you can, take the tree outside for a few hours, or leave the windows open as much as possible.
