As you may have seen, fertilizing houseplants can ultimately be quite a simple practice.
If you use the right products and apply them on a seasonal schedule, your houseplants will look radiant and grow healthily for your enjoyment.
Liquid Fertilizers: These should be used a little more frequently than granular fertilizers,
They have the advantage of being able to be better dosed, and above all, they can be diluted with irrigation water.
Their distribution is therefore more uniform for the roots.
Organic liquid houseplant fertilizers are mainly made from seaweed, fish emulsion, compost tea, worm tea, liquid bone meal, rock phosphate, herbal extracts and humic acids.
Granular fertilizers: they come in two forms: loose granules or compressed cones.
Granular fertilizers are sprinkled on the surface of the soil.
The cones are to be pushed into the ground to be more easily in contact with the roots of the plants.
A quick check of the ingredient list on the label will tell you what the fertilizer is made of.
If you don't see any ingredient list, it is most likely a synthetic fertilizer.
Slow-release fertilizers: Also called time-release fertilizers, slow-release houseplant fertilizers are usually chemically made.
Liquid nutrients are encapsulated in a kind of capsules.
This coating breaks down slowly and releases nutrients in low doses over a long period.
They have the advantage of having to fertilize less often.
It is certainly practical, but not very ecological.
You should make sure your houseplant fertilizer also contains a small amount of these nutrients, sometimes called trace minerals.
The ideal fertilizer is an organic fertilizer for indoor plants.
Macro- and micronutrients are obtained naturally and not from chemicals synthesized in the laboratory.
Organic fertilizers are made from plant, animal or mineral components.
Symbolically, understand that a plant functions like a human body.
Using a synthetic fertilizer is equivalent to an infusion of vitamins.
Using an organic fertilizer instead creates a symbiosis between the plant and the life of its potting soil or soil.

Même si la plupart des plantes d’intérieur demeurent vertes toute l’année, en fait, leur croissance est nulle ou presque pendant l’hiver, quand les jours sont courts et l’éclairage sévèrement réduit.
Les fertiliser à cette saison tend à stimuler une croissance étiolée, avec des tiges minces et des feuilles vert pâle : ce n’est pas l’idéal!
Donc, mieux vaut seulement fertiliser ses plantes quand elles poussent, normalement donc de mars à octobre.
Ne fertilisez que les plantes en croissance active.
Peu importe la saison, une plante qui ne montre pas de signe de croissance ne sera pas capable d’absorber correctement les minéraux qui peuvent alors s’accumuler dans le terreau et endommager les racines.

La fertilisation est essentielle pour relancer la croissance des plantes après l’hiver, car le terreau peut être appauvri et ne suffit plus à répondre aux besoins nutritionnels des végétaux. Un apport en nutriments leur permet de produire de nouvelles feuilles, fleurs ou tiges de manière saine et équilibrée.
Pour optimiser les bienfaits de la taille et de la fertilisation, commencez par la taille, puis attendez quelques jours avant de fertiliser pour éviter de stresser la plante. Arrosez légèrement avant d’appliquer l’engrais pour une meilleure absorption.
Le printemps est la saison idéale pour prendre soin de vos plantes d’intérieur.
Vous pouvez appliquer un engrais liquide tous les 15 jours, ou utiliser un engrais à libération lente selon les recommandations du fabricant.

Fertilize your houseplants in the spring.
You can start fertilizing your houseplants about 8 weeks before the last spring frost.
As in the vegetable garden, the ice saints are an ancestral landmark that has proven its worth.
This means starting to apply fertilizer in mid-March.
At this time, the days begin to lengthen noticeably, and houseplants go from a semi-dormant state to a period of active growth.
If you use a liquid fertilizer, apply half the recommended dose, once a month until summer.
Fertilize indoor plants in summer.
When summer arrives, it's time to switch to a more regular schedule of houseplant fertilization.
The frequency of summer fertilizer applications depends on the type of fertilizer you use.
Natural liquid fertilizers are applied more frequently, every two weeks, or weekly for fast-growing plants.
Granulated products are to be used less frequently, about once every month or every two months.
Fertilize indoor plants in the fall.
About 8 weeks before the first expected fall frost, reduce the amounts and frequency of your fertilizers.
This means that from mid-August you can halve the amount of fertilizer and extend the interval between two fertilizations.
Fertilize indoor plants in winter.
Most houseplants are not in a state of active growth during the winter and therefore should not be fertilized.
There are a few exceptions to this rule.
Some plants, such as orchids for example, can stay in bloom all winter long if they have enough nutrients and light.
In this case, an application of a half dose of liquid fertilizer in the middle of winter can be envisaged.
The case of repotting: If you have just repotted your plant with good quality soil, you can refrain from applying fertilizer during the first 1 or 2 months.
Outside temperate climate: This calendar works assuming you live in a temperate climate.
In a climate that doesn't experience regular winter frosts, continue to fertilize your houseplants throughout the winter, but do so at half the amount and frequency of your summer applications.
And if you live in a tropical climate, where it's always hot, keep fertilizing your houseplants in the summer all year round.
