Urban gardens, it is best to control irrigation with humidity probes

Today they are fashionable in the environments of the big cities and within them, urban gardens. Plantae starts the irrigation controlled by sensors in an orchard located in Horts del Pla in the province of Girona.

What are urban gardens?

They are spaces intended primarily for the cultivation of vegetables, fruits, aromatic plants, legumes and even medicinal plants and which are installed in indoor or outdoor areas, normally for private use.

The fundamental objective is to obtain healthy products that can be consumed directly.

How do you make an urban garden?

The main thing is to have arable land. It can also be done on terraces with stackable, vertical or horizontal pots.

To cultivate an urban garden we must take into account several factors:

  • The risk of frost, especially if they are late.
  • The number of hours of the sun.
  • The type of land that we put or have.
  • The possibilities of irrigation, very convenient drip.
  • Type of crops suitable for the chosen place and adapted to the weather.

Once the terrain has been chosen, we must follow the steps:

  • Prepare the land with a plow to remove the arable part. Remove stones and bury branches that can serve as compost.
  • Se puede cubrir el terreno en la época invernal con un plástico oscuro para que todas las hierbas y restos de otras plantaciones se conviertan en compost. Lo quitaremos al momento de sembrar o trasplantar las plantitas. De esta forma la tierra está mucho más manejable y suelta para hacer la plantación.
  • Prepare the seedbeds and, at the ideal time for each crop, depending on the location and hours of sunshine, transplant them into terraces.
  • If we do not have seedbeds we can use a plant nursery to transplant.

  • Los bancales se separan por zonas idóneas para cada tipo de cultivo. Los podemos cubrir con una malla anti-hierbas y en ella con ayuda de un soplete hacer un agujero, aproximadamente de 4 centímetros, para poder hacer la plantación. El soplete hace que la malla no se deshaga.
  • With the help of a gardening punch, we will make a sufficient hole to place the plant without shrinking the roots.
  • Make furrows in the beds, adapted to each crop. Water when transplanting.
  • Guide the plants that need it when planting or growing as happens with peppers, tomatoes, pickles, green beans and others.
  • Dig the weeds and aerate the soil from time to time. Irrigate by furrow, sprinkler or drip as it is convenient.
  • Some plants must have a distance of at least one meter between one and the next due to their branches, such as zucchini, pumpkins, eggplants, cucumbers and artichokes. Tomatoes and peppers reach half a meter. The onions can be about eight inches apart.

Home gardens are the prelude to urban gardens. Used since ancient times to feed the family nucleus, today they move to the city and its surroundings to consume fresh and healthy products in the form of urban gardens.

Planting dates adapted to the northern area of ​​Spain

We already mentioned that in the winter time the land should rest, better with coverage.

At the end of March or beginning of April we plant:

  • Onions, a una distancia de unos 30 centímetros alineadas y muy favorable con malla anti-hierbas.
  • Potatoes, sow whenever they have a sprout. They can be cut without problem if they are very large.
  • Coles, se trasplanta y se pueden colocar con malla anti-hierbas separadas medio metro.
  • Peas, planted or transplanted and keep in mind that you have to put a guide for them to climb.

At the end of April or beginning of May

If the weather permits, at the end of April, although it is favorable to protect the plant with a transparent bottle from which we remove the base.

Tomates y pimientos con malla antihierbas
  • Peppers, plantar con la tierra protegida con malla anti-hierbas con una separación de medio metro.
  • Tomatoes, lo mismo que los pimientos, con malla anti-hierbas y separados medio metro. Recomendable plantar una hilera de tomates y otra de pimientos, porque crecen menos y así a los tomates les llega más luz solar.
  • Zucchini, plant one meter apart because they have a lot of branches.

Pumpkins, planted near the onions, produce their fruit when the onions are ready to be picked and thus the pumpkins climb through their holes. Another option is to plant them at the ends of the garden, they can reach four or five meters when crawling. They can be consumed tender or ripe. If they are picked ripe and a little stem is left, they can last all winter.

Acelgas, con malla anti-hierbas y separadas unos 40 centímetros, se van consumiendo las hojas dejando las centrales, para tener toda la temporada. Son resistentes al frío.

Table beets, the same as chard.

Fresas, siempre con malla anti-hierbas, separadas unos 20 centímetros, se reproducen mucho y pueden durar de una temporada para otra, por eso debemos plantarlas en un extremo para no cubrir la planta en invierno.

Berenjenas, separadas medio metro y con malla anti-hierbas. Necesitan tutor.

Prune eggplants

Green beans, they are sown from the beginning of May and it is advisable to sow others at the end, to have them for longer. Even in the month of June we can do a third sowing. Always in rows to put climbing nets or stakes. There are short varieties, which are usually round pod beans.

Pruning tomatoes, peppers and eggplants

podar tomates
  • Maintain a main branch.
  • We must support the plants and remove the suckers.
  • They are the buds that emerge between the main stem and the leaves.
  • Be careful not to remove the shoots of future tomatoes.

Caring for an urban garden

In most orchards the planting is done by furrows. Irrigation is normally done by sprinkling or dripping.

For the irrigation to be correct we must take into account several factors:

  • That the ground is level.
  • Important that we have separate plots.
  • That the terrain is loamy or loamy.
  • Controlar la acumulación de sales. Para ello es conveniente cambiar el cultivo de lugar entre una temporada y la siguiente. Cada planta requiere unos nutrientes y el cambio de lugar hace que las sales se acumulen menos.

Plantae sensors in urban gardens

Our technicians study the crop, the type of terrain and the climate of the area. We assess the number of sensors and the ideal situation.

The sensors measure us:

  • The humidity of the subsoil adapting the depth to the cultivation according to the rooting.
  • Subsoil temperature.
  • Conductivity and therefore salinity values.
  • Measurement of the water flow to irrigate with a flow meter and irrigation time.
  • We can have information in real time on our mobile phone or tablet.

Advantages of urban gardens

We must always consider that its cultivation has to be pleasant, that it motivates us and that we can dedicate time to it.

Having an urban garden needs some care and dedication but it has its reward

  • We can have fresh products.
  • With proper care, the garden is ecological.
  • We can keep canned products, such as tomatoes, peppers, pickles, peas and dispose of them all year round.
  • Enjoy the outdoors when we take care of it.
  • Share our vegetables with family and friends.
  • Enjoy nature.
