One of the most important and rewarding decisions is the choice of shade treesThese trees not only beautify the surroundings and add character to the garden, but they also create cool areas, provide protection from the intense sun, and help maintain a more comfortable temperature, especially during the warmer months.
Choosing the shade tree suitable It depends on factors such as the region's climate, the size of the garden, proximity to structures, the aggressiveness of its roots, and the maintenance required by each species. It's essential to consider the type of leaves (deciduous or evergreen), growth rate, resistance to frost and drought, and the amount of waste they can generate. Additionally, some trees provide spectacular blooms, changing autumnal hues, or even delicious fruits, which add both ornamental and functional value to your green space.

Basic care for a healthy shade tree
- Select the species that best adapts to both the climate and the Available space and the type of soil.
- Plant at the recommended distance from buildings and other plants to avoid future conflicts.
- Water according to the needs of the species and the local climate. Many young trees require extra care in the early years, especially in the face of frost or drought.
- Fertilize during the growing season (spring to early autumn) with organic matter appropriate to the type of tree.
- Prune lightly to maintain shape and avoid accumulation of dry or weak branches.
Remember that the root system requires sufficient space to develop. If possible, avoid planting within 1 meter of walls or infrastructure and regularly check the tree's condition.
