Do you have a balcony and a lot of free time? Well then do not hesitate: go ahead and create your urban garden. Although the space you have is small, there are several edible plants that will grow luxuriously in pots, planters and even in trays.

If you cannot leave home, for whatever reason, and you would like to learn how to grow what will be the ingredients of the future healthy recipes that you will prepare, stay with us so we can tell you what you need to have a garden on your balcony.

What does it take to create an urban garden on the balcony?

You may need a seedbed if you want to sow seeds

Little thing. The fundamental thing is that you have the desire and enthusiasm to grow some plants on the balcony, but one some plants, if not ones that will serve as food. In addition, you should bear in mind that the growth rate they have is quite fast, since most are annual, that is, in just one year they germinate, grow, flower and dry. But no, don't worry: you won't have to wait a year to harvest them. In fact, most of them will be ready in 2-3 months, such as lettuce or chard.

Now what you will also need is the following:

  • Light (or clarity): most garden plants require a lot of light. It is not necessary for the balcony to be sunny, but it is recommended that when you go out to it there is a lot of light.
  • Seedbeds: If you want to be aware of the whole process and you are going to get some seeds, as seedbeds you can use milk containers or yogurt glasses (think about washing them with water and making a hole in the base before using them), cardboard boxes laminated (make a hole in the base), and of course pots, or plastic trays (with a hole in the base).
  • Flowerpots and the like: to grow the plants. If you are a handyman and you have or can get wooden planks without moving much, you can build an urban garden table and fill it with substrate to grow.
    Another option is to buy one, like this one they sell here! for example.
  • Substratum: the universal substrate mixed with 30% perlite will serve you, but since you are going to create an urban garden it is interesting to take advantage of the urban garden substrate that they already sell prepared (for sale here!).

They are not very suitable for urban gardens, but if you have a large and deep pot, about 40cm in diameter by more or less the same depth, you can cultivate them (Although yes, put a bulb for each pot). They require moderate watering.

How to avoid pests and diseases in the urban balcony garden?

The answer is as simple as it is complicated: taking good care of the plants 🙂. For that, it is important to take into account the following:


Garden plants generally want a lot of water (except for chard, broad beans, garlic, and onions, which are probably the ones that want the least). So that there are no problems, it is advisable to check the humidity of the substrate before wateringFor example by inserting a thin wooden stick or digging a bit with your fingers.


As they are plants suitable for human consumption (they or some of their parts), organic fertilizers should be used. As such there are many: compost, mulch, herbivorous animal manure ... If you can't get any of these, don't worry, as Eggshells, wood ashes (at room temperature), natural rooting agents such as lentils will also work. (here! explains how to do it), or others that we explain in this article.


Just as important as watering and fertilizing is being clear from the beginning that plants need space, some more than others. That space should be larger as they grow. For this reason, when you choose the plants for your urban garden, find out well about the size they will have once they are adults, since they will probably require 2-3 transplants before being planted in the final pot. But how do you know? Well, If the roots come out of the drainage holes, or if you see that they have already occupied the entire container, then it will be when you should move them to larger pots.
