Still talking about ornamental ones, we cannot fail to mention the Yew, a tree belonging to the Taxaceae family. It is a slow growing evergreen conifer with an erect stem that can reach 20 meters in height. Its bark is brown tending to reddish, which turns gray in old age and tends to peel.

The main phytotherapeutic properties are:
It prefers well-drained soils rich in minerals, with a neutral tendency,
It is advisable to fertilize at least once a year using slow release granular fertilizers. It is used to being in sunny places, even directly hit by the sun's rays; but it does not suffer when it is in semi-shaded areas. It does not require watering, except during the hot months, when it is sufficient to wet it once a month to avoid water stagnation that could cause deterioration of the roots.
The flowering plum is undoubtedly one of the most used ornamental trees. It is a tree belonging to the Rosaceae family. It is a very robust and luxuriant plant, with an erect stem, whose height can reach up to 8-12 meters. The leaves are of medium size, elongated and with a continuous margin, with a dark green color.

They require mixed soils that have no calcareous component; it is preferable that they are not placed near other trees, but that they remain isolated, in order to expand freely. They prefer sunny areas full of light as they fear the shade, even if they do not live well in excessively hot or arid climates. They are very resistant to low temperatures: up to -20 degrees. It is advisable to water at least once a month and only during the early stages of the tree's life, subsequently, for adult specimens, rainwater is sufficient. Fertilization is recommended using fertilizers enriched with mature manure or humus which must be added to specific products for tall trees. The process should be repeated twice a year.
