What to consider before planting a tree on a terrace or attic
Before selecting and placing a tree, it's important to consider several critical aspects for the safety, health of the plant, and the success of the project:
- Weight and structureCheck the load-bearing capacity of the slab, as a pot containing a tree, substrate, and water can easily exceed 400–600 kg. This is especially essential in attics and building terraces to avoid structural risks.
- Pot size and typeChoose large, sturdy pots (minimum 60-80 cm deep and XNUMX-XNUMX inches in diameter). Make sure they have drainage holes and add a layer of gravel or expanded clay to the bottom.
- Substrate and drainageUse quality, aerated, and fertile mixes appropriate for the selected species. Drain well to avoid waterlogging and root rot.
- Light and locationConsider the terrace's orientation. Most trees require full sun, but there are options for partial shade or more sheltered spots. Avoid excessively windy corners.
- Anchoring and protectionWind is the greatest enemy of tall trees. Install internal anchoring systems or perimeter fences. Consider using windbreaks or placing planters near protective walls.
- Irrigation and fertilizationPotted trees require more frequent watering and regular fertilization, as the substrate depletes and dries out more quickly than in the ground. Adjust the frequency according to the season and the species.
- Pruning and maintenance: Prune lightly to control size and maintain shape. Repot every 2-3 years or replace the top soil.
Taking care of these details from the beginning is key to enjoying healthy trees, managing their growth, and ensuring the safety of your outdoor space.
