However, many chemical fertilizers found on the market contain substances  toxic to  the environment  and our health. In fact, they can contaminate groundwater, causing damage to  flora and fauna  , also causing excessive proliferation of algae and deteriorating water quality.

It is better to opt for  natural fertilizers,  which allow us to feed our plants in a sustainable and safe way. And some of them are great  pesticides too!

Natural or DIY fertilizers provide plants with several  essential nutrients:  such as  nitrogen, phosphorus and potassium  . They are composed of organic materials such as  manure, compost and algae  , and they keep the soil in optimal conditions, promoting  the growth of plants  naturally.

What to use against insects on plants

One of the best known and most used fertilizers is beer: a fantastic natural product for plants and also an excellent  pesticide.

It lends itself perfectly to keeping  insects, snails and wasps away  . How do we do it? If we want to protect our plants and shrubs from insect invasion, all we have to do is fill a container with beer and bury it so that the edge is level with the ground. This trick scares away snails, but also wasps if we add a little sugar.
