You have beautiful, big, radiant plants. Everything is going well, but at some point you start to notice that your plant is looking a bit thin, its leaves have fallen off, it is looking sad, yellow and no longer gives flowers or grows or anything.
It is very possible that your plant has a nutrient problem and no, your Calathea is not anaemic, it just needs a little fertilizer.
does my plant need fertiliser?
Plants are amazing living things, capable of generating their own food using water, sunlight and nutrients from the substrate. When plants are outdoors, the substrate is progressively enriched by rain and other factors; but when it comes to indoor potted plants, it is common for the substrate to fall short of meeting the plants' nutritional requirements.

If the plant is in an impoverished substrate, you will start to notice that the plant looks droopy, doesn't grow, doesn't flower, loses leaves and looks a bit sparse.
But this is not the only time you should use fertilisers or fertilisers, you don't have to go to this extreme. You can use fertiliser when:
- The plant is in the growing season. Almost all houseplants grow and develop most in the months between spring and summer, but this varies from species to species. See your Be.Green care sheet or our website.

- The roots of the plant have taken up all the substrate. It happens that when they require transplanting, many plants form a large network of roots that occupy the entire root ball of substrate in the pot. At this point it is urgent to move the plant to a larger pot and supplement the change with a little compost.

- The low temperatures are coming. In autumn a last cycle of fertiliser should be applied, so that the plant is prepared for the onset of winter and can survive it successfully.

They are not all the same: types of compost and fertiliser
Fertilisers or composts are nutrient-laden products that will enrich the substrate in which the plant is planted, improve its quality and enhance the plants' development by providing it with everything it needs to grow. Although some people use the word fertiliser and compost as synonyms, there are those who make the distinction that fertilisers are inorganic compounds and compost are organic in origin.

There are many types of fertilisers and composts on the market. There are universal fertilisers for indoor plants, while others are very specific for certain types of plants. Most of these fertilisers are composed of the main nutrients which are:
- Nitrogen: stimulates plant growth, makes plants lush and creates juicy shoots. It should be avoided in winter, because it increases sensitivity to cold.
- Phosphorus: contributes to root development, stimulates the production of flowers and fruits, as well as resistant stems.
- Potassium: this chemical compound provides disease resistance and balances nitrogen, as well as protecting plants from temperature extremes.
In addition to these nutrients, iron, calcium, sulphur and magnesium are also required. Almost all fertilisers offer a balanced mix of these nutrients to suit the requirements of each plant. Some species require more iron, others prefer more acidic soils, while others need nitrogen.
how to use fertilisers
- Find the right fertiliser
Before you buy a fertiliser to feed your little green army, you need to know that you require a fertiliser that suits the particular needs of the plant species you have. There are universal fertilisers for houseplants, others for succulents and cacti, among others.

- Water first
Do not apply fertiliser to dry soil. Water first, without puddling, wait an hour and then apply the fertilizer. The water will help dissolve the nutrients and carry them to the roots.

- Read the instructions
It seems like an obvious thing to do, but many plants have died from overfeeding because people don't read the packaging and don't pay attention to measurements and application methods. Read the instructions carefully and follow them to the letter, especially in terms of quantity and frequency.

- liquid, granular or sticks?
You can find liquid fertilisers, which should be mixed with water and watered onto the plant. Others are granular and should be sprinkled on the substrate and mixed a little. My favourites are slow or extended release fertilisers. They come in the form of sticks or tablets that are inserted into a small hole near the substrate and release their nutrients every time you water. They last longer and because they are gradual acting, it is easier to use the controlled dose.
- Avoid overdoing it
Too much nutrient will not make your plant look prettier, grow faster or give more flowers. Too much fertiliser can burn the roots, stunt growth and even kill your plant. So don't go overboard, in this case it's better to have too little than too much.
