FAQ - Plant Knowledge

What are the ingredients in the FARBIO® liquid fertilizers?

The FARBIO® organic liquid fertilizers have a natural origin, mainly vegetable. Currently, the Nitrogen Bio-Boost still has an animal origin. The organic active ingredients are highly effective thanks to important micro and macro nutrients as well as innovative nano technology. We use selected and 100% organic ingredients - Ecocert certified! Safe ingredients for humans, animals and bees. Not tested on animals!

Can you also add the FARBIO® foliar fertilizer to the irrigation water?

Yes, the FARBIO® foliar fertilizers can be applied to the leaves using a spray bottle or mixed with the irrigation water. With the FARBIO® NPK basic supply, you can only fertilize with the irrigation water.

Which FARBIO® organic liquid fertilizer is right for you?

Our FARBIO® NPK organic liquid fertilizer for green plants is the basic supply for your indoor plants. As long as you simply care about keeping your plants healthy, we recommend this one! The FARBIO® Nitrogen Bio-Boost is ideal for particularly fast growth and the Bio-FARBIO® micro-complex supports the natural defenses with micronutrients. This is top-class plant care, but as a foliar fertilizer it has the advantage that the nutrients are absorbed super quickly via the leaves! In general, foliar fertilizers are great if you want to keep the soil rather dry to prevent pest infestations, mold on the soil, etc. Of course, all 3 products are also compatible!

Can FARBIO® organic liquid fertilizers also be used for hydroponics and mineral substrates (perlite, expanded clay, pumice, lava etc.)?

The complete FARBIO® product portfolio can be used safely for your hydroponics and mineral substrates and will not burn the roots! However, we note that the NPK organic liquid fertilizer is brown in color and can stain the water.

Are all FARBIO® liquid fertilizers compatible with each other?

All fertilizers are compatible with each other. Our NPK organic liquid fertilizers can be used at the same time as the Bio-Microcomplex and Nitrogen Bio-Boost. For the most effective absorption of the nutrients, we recommend alternating application of the foliar fertilizers: If applied every 2 weeks, spray each foliar fertilizer onto the leaves of your plant once a month.

Can leaves variegated by FARBIO® foliar fertilizer turn green?

Variegation is caused by mutations in chloroplasts. Nutrients or our FARBIO® foliar fertilizers have no influence on this!

Can I over-fertilize with FARBIO® liquid fertilizers?

Over-fertilization with organic active substances is almost impossible. Nevertheless, you should stick to the dosage instructions. You can tell if your indoor plants are over-fertilized by the leaves curling up from the edges. Leaf edges may turn brown.

Which nutrients do plants need and which nutrients should be fertilized?

The FARBIO® Nitrogen Bio-Boost mainly supplies the plant with nitrogen for the formation of leaf mass and rapid growth. The plant needs a complete nutrient profile, which is why our NPK fertilizer with the main nutrients nitrogen, phosphorus and potassium should always form the basis of your plant care. The plant also needs micronutrients, which you can find in our FARBIO® organic micro-complex!

How often should you fertilize heavy feeders like Monstera and Philodendron?

Houseplants also have heavy, medium and weak feeders. Monstera, philodendron, cala and alocasia are among the less frugal green plants that have a high nutrient requirement. During their growth phase (spring and summer), they should be fertilized once a week with an organic liquid fertilizer.

Can you fertilize despite root damage?

Watering too much can lead to root rot: roots begin to rot, neither water nor nutrients can be transported and the plant dies as a result. If you are worried that your plant is suffering from root rot, you should take it out of the pot and look at the roots. These often smell foul and are very slippery when root rot has occurred. These roots should then be removed if not all are affected. After that you should repot. FARBIO® foliar fertilizers are the best way to care for them, because the rotten roots meant that the plant was unable to absorb any or only a few nutrients for a long time!

How do you fertilize succulents and cacti?

Succulents grow more slowly and therefore require small amounts of nutrients. The main nutrients nitrogen, phosphorus and potassium (NPK) are important for succulents. In spring and summer you should fertilize with FARBIO® organic liquid fertilizers about every four to six weeks.
