We need to consider:
- extension of the terrace
- weather conditions
- type of sunshine
- size and constituent material of the containers to be used
- coexistence between plants
- any harmful factors
The fundamental difference between a terrace and a garden consists in the fact that the plants cannot be housed in the ground, but have pots or jars, with variable dimensions.
Another diversifying factor is represented by the type of irrigation, which could cause harmful phenomena of water stagnation; for this reason it is advisable to alternate the waterings with nebulisations and to provide the saucers with gravel or pebbles.
Finally, it is always preferable to use terracotta containers or made of porous material that is able to ensure correct transpiration of the soil.
Plants to furnish the terrace
- tree plants (if the terrace is very large)
- shrubby plants
- climbing plants (to enhance vertical areas such as espaliers or partitions)
- evergreen plants (to keep the terrace alive even during the winter months)
- herbaceous plants
- flowering plants (for ornamental purposes)
- succulent plants (if climatic conditions permit)
