Jars and containers
In the presence of a balcony, the use of pots is essential for the different types of vegetables that you want to grow.
It is recommended to choose terracotta pots, which facilitate the oxygenation of the soil in which the plant was planted. Since space is limited, some types of vegetables can be grown in the same pot (choose, for this use, the rectangular pots, which allow the optimization of the space). The single round pots are very useful for growing perennial aromatic plants (such as rosemary): in this way it will not be necessary to stress the plant unnecessarily every time you go to place a new vegetable next to it.
There are also plastic pots on the market, which are increasingly popular: although they do not favor oxygenation of the soil, they are lighter than terracotta containers. Their use is therefore recommended if plants are grown that need to be moved several times during the course of a day.
The pots must be filled with soil, after taking care to ensure drainage with the appropriate clay balls (or with gravel), which must be placed on the bottom of the pot itself.
Once the different vegetables are planted, it is also important that the watering is carried out without wetting the plants: the water must be poured directly on the earth. It is also preferable that the plants, in the summer months, are watered early in the morning: this will prevent the water in the pot from heating and evaporating.
What to grow
Due to the limited space, the cultivation of vegetables that do not require a large environment to develop is recommended. There are plants of all kinds, to be grown at any time of the year. In winter, garlic, onions, salad, spinach, radishes, peas, rocket, chillies and cabbage can be planted. With the arrival of spring, you can make room for aromatic plants (rosemary, sage, lavender and basil), berries (for which plastic pots will be needed), carrots, tomatoes, zucchini and peppers. In summer (starting from September) leeks, endives, turnip greens, beets can be sown. In the autumn period you can instead give space to fennel, broccoli, valerian, chicory.
As you can see, a vegetable garden built on your terrace guarantees the presence throughout the year of a large variety of fresh vegetables.
