To grow and develop the root system, to form leaves and flowers, plants need very specific nutrients. In the land for flowers, which you buy ready-made, the necessary substances are there, but they are only enough for the first time. Later flower soil necessarily fertilized to maintain a certain stock of batteries.
In this article, you will learn how to feed indoor flowers at home and how to apply fertilizer correctly.
How to fertilize indoor flowers at home: the correct dosage
First of all, you need to take care of a sufficient amount of nutrients in those months when the plant develops and blooms. In the dormant period, when the growth stops for a while, indoor flowers are not needed.
Not all plants have the same appetite. Before fertilizing indoor plants, find out about the correct dosage - such information can be found in any botanical directory, you can get a recommendation in the store where you buy your "green pet". There are terrible “gluttons”, such as bougainvillea, hydrangea (Hydrangea macrophylla) and some palm trees. But there are also “hunger strikers”, which include cordyline, sansevieria, yucca (Yucca). These indoor plants have enough mineral fertilizers in very small portions.
Remember: it is not enough to feed some home cultures as harmful as other types of fertilizing too much. The frequency of feeding indoor plants at home is not necessary to comply with the accuracy of one day, but it is important to adhere to it.
The composition of fertilizers for feeding indoor plants at home
The composition of the best fertilizers for indoor plants necessarily include three main elements of nutrition.
- Nitrogen (abbreviated N packaged) ensures the growth of shoots and leaves, the formation of a sufficient amount of chlorophyll.
- Phosphorus (P) necessary for the normal development of the roots, the formation of buds and ripening of seeds and fruits.
- Potassium (K) strengthens plant tissue and increases resistance to diseases and pests. In addition, it is also necessary for the formation of flowers.
When deciding how to feed indoor plants at home, remember that the flower should not be deficient in microelements, even if they need very little. To trace elements include iron, copper, manganese, magnesium, boron and some others.
You can assume that each fertilizer for indoor flowers, which is proposed under the name "Complex", contains all vital substances in a balanced amount. Many packages indicate the ratio of three main elements, always in the same order N, P, K. If 7: 6: 7 stands there, it means that the fertilizer contains 7 parts of nitrogen, 6 parts of phosphorus and 7 parts of potassium. The 7: 4: 5 numbers mean that nitrogen predominates in top dressing for indoor plants, and the 4: 6: 4 numbers indicate an increased phosphorus content compared to nitrogen and potassium. Different trace elements are often not indicated on the package, but they are added to the composition of any complex fertilizer.
Than you can fertilize indoor flowers at home for better growth
He who is a little versed in fertilizers and willingly experiments, can purposefully control the development of domestic crops. What is to feed the plants for their best growth?
Young plants that need to develop vigorously should receive fertilizers with a slight predominance of nitrogen or equal parts of nitrogen and potassium. Flowers in the period of budding and flowering are very necessary phosphorus and potassium. Fertilizers with an increasing ratio of elements (eg, 8: 12: 16) are most suitable for them. After flowering, they should use another fertilizer.
The best food for indoor plants such as cacti should be low in nitrogen so that they grow compact. Special fertilizers for cacti, which are sold in finished form, are made with this feature in mind. Such fertilizers can be recommended for other succulent plants.
And how to feed potted flowers that are sensitive to lime, such as azaleas? They need so-called acidic fertilizers, with a pH below 6. Ask at the store special fertilizers for azaleas, which are produced by several companies. Similar fertilizers can be used for other plants that are sensitive to lime.
It is also important to know about the best way to feed salt-sensitive indoor plants, such as ferns, orchids and bromeliads. They can be fed the usual complex fertilizer for home colors but make about half the recommended dose in the instructions.
For decorative leaf and flowering plants, if you want to save time and effort, you can use the usual complex fertilizers. The plant absorbs primarily those substances that it needs at the moment most.
The best dressing for indoor plants: mineral and organic fertilizers for flowers
The discussion continues over and over again than to fertilize indoor flowers at home: organic supplements (often referred to by the term "biological") or mineral (often called "artificial").
In the case of indoor plants, these disputes have no meaning. A crucial role for plants is played by the availability of quantities of nitrogen, phosphorus and potassium. They are introduced in the form of organic or artificially, in the industry of prepared mineral fertilizer, plants do not distinguish. In their action, these types of fertilizers are somewhat different, and you should know something about it.
In mineral fertilizer for indoor flowers, nutrients are present in such a form that they can be immediately absorbed by the plant. If the plant suffers from a lack of batteries, then as an emergency, you should always use a variety of mineral fertilizers (which include most floral fertilizers).
Organic fertilizers for indoor plants release nutrients to the environment more slowly. The most common organic fertilizers, which are considered manure and compost, can hardly be used in flower pots. Here life in the soil is not active enough; there is no necessary number of microorganisms and earthworms, the presence of which is necessary for the conversion of complex chemical compounds into simpler ones that are easily absorbed by the roots of plants.
In a very narrow framework, you can afford the use of biological substances, if you slightly increase the recommended intervals between the next fertilizer application and use old home remedies. Exhausted mineral water contains certain amounts of trace elements. Coffee grounds, which are applied superficially, or tea already in sleep, are only slightly sprinkled with earth, have certain properties of fertilizers. But it is not necessary to completely translate indoor flowers to such household organic fertilizers!
Currently, there are special organic liquid complex fertilizers for indoor plants.
Liquid fertilizers for indoor plants, briquettes and flower tablets
Liquid fertilizers for indoor plants, which are added to water for irrigation, are used most often. Usually the bottle cap serves as a dispenser.
Never use more fertilizer than recommended on the label.
In the guidelines for the care of many plants, you will find the label “weak concentration”. This means that half of the indicated dose is sufficient. Liquid fertilizer for indoor flowers for a short time. After a week or two, depending on the type of plant, you need to make them again.
Salts that are produced and sold in the form of powders are not very convenient to use, because you have to dose yourself (usually 1-2 g per 1 l of water). To do this, we need accurate pharmacy scales. And in this case it is necessary to apply fertilizer often.
Long-acting fertilizer for indoor plants at home is mixed with the soil when planting plants in a pot. For many months, they are a stable source of nutrients. Most often, nutrition is enough for the entire growth season. Foliar nutrition is produced by special liquid fertilizers of very fast action, which are well suited for fertilizing plants suffering from acute shortage of batteries. Such fertilizers are sprayed on the leaves, shoots and for them. It is better to do spraying on the street or in the bathroom, so as not to hurt the furniture.
If you do not know how you can fertilize indoor flowers, try using ready-made briquettes or tablets. They are simply buried in the ground next to the wall of the pot. They gradually release nutrients over a long time in strictly defined quantities.
If it is not about very “hungry” plants, one briquette or one tablet is enough for about a month.
Caution! No matter what fertilizer you use, they should be kept out of the reach of children. Although they are not very poisonous, they are capable of causing some harm.
Next, you will learn how to properly fertilize indoor flowers at home.
Proper fertilization for indoor plants
Most plants are fed from about March / April to the end of August.
- Find out exactly how often and in what quantity you need to feed certain plants.
- When applying fertilizer adhere to the recommendations on the use of fertilizer contained on the package.
- Make sure that the fertilizer solution does not fall on the leaves. If this happens to a plant with dense foliage, it should be washed well in the shower. Otherwise spots will appear on the leaves.
- Fertilizers are recommended to be applied only to damp soil and in no case completely dry. Otherwise, due to the high concentration of chemical compounds, root burns are possible.
- Sick plants should not be prompted to grow with top dressing. They first need strength to recover.
- Newly transplanted plants do not need feeding in the first six weeks, as there is an adequate supply of nutrients in fresh soil.
Top dressing of indoor plants is not difficult, but it does not tolerate negligence.
Few fertilizers! If the plant suffers from a lack of nutrients, then it looks sick. The surest signs of a lack of batteries are:
- Slow growth
- Loose stems
- Few flowers
- Lightened leaves, especially the lower
- Reset bottom leaves
What to do: Immediately feed with mineral fertilizer and feed from the next day with the recommended frequency. The plant will recover gradually over time.
A lot of fertilizer! If one of the following symptoms is found, it may be a sign of excess fertilizer:
- Listlessness or deformation of the leaves
- Brown spots and burnt edges of leaves
- White peel - the deposition of calcium salts on pots and the surface of the substrate
What to do: transplant or wash. To put the pot in the sink, it is better to have a pebble on the 3, so that water can flow out of the hole in the bottom of the pot. For half an hour, run water through the ground. The jet should not be strong. In the subsequent soil give a little dry again, and then begin a normal regular watering and fertilizing.
Sensitive to elevated salt concentrations of plants, such as ferns, azaleas, primroses, orchids, should always be fed up quite a bit.
Iron deficiency! Sometimes you can see indoor plants that suffer from a lack of a very specific element, such as iron. In this case, they suffer from jaundice, chlorosis. Especially sensitive to iron deficiency are citrus fruits, brunfelsia, hydrangeas (Hydrangea macrophylla).
Recognize iron deficiency can be on the leaves: they become light yellow, only the leaf veins, even the thinnest, remain green. This phenomenon is caused by a high content of lime (calcium salts) in the water for irrigation.
What to do: top dressing will not help here; you need to fill the lack of iron. Buy ferrous sulfate and dissolve 0,5 g in 1 l of water. 50 ml of this solution water the plant. This procedure should be repeated several times intermittently on 5-7 days, but use fresh solution for each treatment. Rusty nail, stuck in a pot with the ground under the plant, in such cases does not help. Perhaps someone succeeded with an iron tablet.
How to make indoor plants to bloom
If you resort to some little tricks, you can make indoor plants to bloom.
- Cut faded flowers, which stimulates the blooming of new ones.
- In some species, shortening and pruning of the tips of the shoots contributes to the development of a greater number of flowering shoots.
- Fertilize for indoor plants only during growth and no more than necessary. Fed plants bloom lazily and become less resistant to diseases and pests.
- Provide plants with maximum illumination in autumn and winter. Ideal: lamp for plants.
- Observe the rest period of certain species. This is especially important for amaryllis (Hyppeastrum), clivia and room callas (Zantedeschia aethipica).
If your bromeliad does not want to bloom, there is a trick with which to correct this situation.
Ethylene, a gas that ripe apples emit, promotes the blooming of fairly large bromeliads. Put the plant on the 1-2 of the week in a plastic bag that lets air in, and put some apples in it. Not earlier than in four weeks a flower will appear on the plant.
