Fertilizing indoor plants: areas of application for FARBIO® fertilizers

Zimmerpflanzen düngen: Anwendungsbereiche der FARBIO® Dünger - FARBIO® - Nachhaltige Bio-Flüssigdünger aus Hamburg

At FARBIO®, we have opted for smaller sizes of fertilizer because we are finally creating a high-quality fertilizer that also makes sense for users who only need to care for a handful of plants. You no longer have to buy one universal fertilizer for all plants or use home remedies that don't work, you can buy smaller sizes that are specially tailored to the plants and thus have maximum effects. FARBIO® is against the waste of raw materials, which is why we want consumers to only be able to buy what they can actually use. Here we present some areas of application of our product innovations and explain what you should consider when fertilizing indoor plants!

When and how often should houseplants be given fertilizer?

A year-round use of our organic fertilizers is possible. We recommend fertilizing once a week from March to October and once a month from November to February. Do indoor plants need to be fertilized in winter? Yes, but the frequency varies depending on the type of plant and whether it is dormant during the winter. The FARBIO® organic liquid fertilizers can be used during the entire growth period of your plant.

Apply fertilizer to houseplants

All of our complete nutrient fertilizers are simply added to the irrigation water and can thus be absorbed by the roots of your plants in the soil. You can find the exact number of drops or milliliters on the products and in our shop. Our FARBIO® foliar fertilizers are simply mixed with water in a spray bottle and then sprayed directly over the foliage of your plant. The advantage: No nutrients are lost in the soil when they are absorbed through the leaves.

But what nutrients do indoor plants need? The nutrients required by plants can be divided into two groups: major nutrients (macronutrients) and trace elements (micronutrients). Not to be forgotten are oxygen, hydrogen and carbon as the essential basis for the growth of your plants.

The main nutrients include nitrogen, phosphorus, potassium, calcium, magnesium and sulphur. Plants need these elements in larger quantities - they are often found in fertilizer.

Trace elements include: iron, copper, zinc, chlorine, manganese, boron and molybdenum. Plants require smaller amounts of these nutrients, but they are important for healthy plant growth.

The most important nutrients for fast growth of your houseplant

For healthy growth, it is important that the plant has ideal conditions and an optimal one nutrient supply is often only achieved with fertilization. Slow-growing plants can grow leaf mass faster again by introducing a fertilizer. Our liquid fertilizers with basic nutrients provide the essential main nutrients nitrogen, phosphorus and potassium. But our special fertilizers also ensure sufficient availability of all other nutrients, since the lack of these substances would otherwise limit the growth of your plant.

A comparison of organic and mineral plant fertilizers - good fertilizers contain NPK

There are different fertilizers - they differ in form, origin and ingredients. The range extends from solid fertilizer sticks to home remedies such as coffee grounds and egg shells, which can be used to fertilize indoor plants, and liquid fertilizers. Organic fertilizers are made from natural ingredients and are a good choice for indoor plants. They are gentle on the environment because they are free of chemical-synthetic substances and are therefore also safe for humans and animals. The nutrient needs of houseplants are sustainably covered by an optimal composition of organic components. They are considered more of a long-term fertilizer because they release active ingredients over a longer period of time. Complete fertilizers contain the essential active ingredients NPK and thus promote the growth of the plant. Mineral fertilizers consist of artificially produced inorganic substances - the risk of over-fertilization and the resulting damage to the roots is significantly higher here, since the nutrients are in the form of salts. Mineral fertilizers can be absorbed more quickly and are directly available in a form that is available to plants. However, if they come in the form of fertilizer sticks, the nutrients must first be transported to the roots of the plant. The environmentally friendly alternative are organic liquid fertilizers - the fertilizers work quickly and deliver the nutrients to the plant as needed. In order to fertilize green plants correctly, attention should be paid to the individual needs of the plant species.

Houseplants fertilize for strong roots

Only a healthy plant has vigorous root growth. A suitable soil substrate is essential, as is a sufficient one nutrient supply . If you are fighting against waterlogging, which damages the roots of your plant, we recommend our FARBIO® foliar fertilizers , which can supply your plants with nutrients without having to water the soil substrate. In this way you support the healthy growth of the roots.

Liquid fertilizer for flowers and fruits

In order for plants to have larger flowers, they should be fertilized regularly and have a suitable location. In order to give the plant enough strength to develop flowers and fruits, sufficient potassium must be introduced into the soil and generally fertilized regularly! When using liquid fertilizers, the advantage is the quick effect: nutrients quickly reach the roots through the substrate and are thus absorbed directly when the plant needs them to develop flowers.

Indoor plant fertilizer for less plant stress

Both biotic and abiotic factors can cause your plant to experience stress and consequently grow less or show other symptoms of stress. Incorporating fertilizers provides your plants with nutrients, making them more resistant to stress, including pests and diseases.

Avoid over-fertilizing when fertilizing indoor plants

Over-fertilization with organic active substances is almost impossible. Nevertheless, the topic of fertilizing is very complex and you should stick to the dosage on the packaging and fertilize houseplants correctly. You can tell if your indoor plants are over-fertilized by the leaves curling up from the edges. If the dosage is incorrect, the edges of the leaves can turn brown.

Recognizing Deficiency Symptoms: Should You Fertilize Your Plant Again?

You haven't fertilized for a long time? After a while, this becomes apparent as a deficiency symptom - then it is high time to use a fertilizer for indoor plants. Especially in the growth phase from March to October, most indoor plants need more fertilizer. In the cold season, on the other hand, you should give your plant less fertilizer.

When a plant's older leaves turn yellow, it's often a sign of nitrogen deficiency. A lack of phosphorus leads to reddish to black discoloration. A lack of potassium causes the plants to wilt despite an adequate water supply. Discoloration of the leaf edges occurs. If there is a lack of magnesium, the older leaves turn yellow, while the veins initially remain green. If there is a zinc deficiency, young leaves turn yellow from the top. A lack of iron and manganese leads to yellowing of young leaves, but the veins initially remain green. A lack of calcium is indicated by brown spots on new leaves. If plants get too little copper, the young leaves curl. Old ones remain dark green.

What else do indoor plants need?

Sufficient water is essential for the preservation of plants, which is why our FARBIO® spray bottle should not be missing when caring for your plants. Many tropical plants need high humidity, which we can only achieve by spraying the leaves regularly. The pH value of the soil is important for indoor plants, because if this is not optimally tailored to their needs, it can inhibit nutrient absorption.
