Hydrangea is not the most whimsical plant, with the cultivation of which even newcomer will cope in gardening. However, in some situations, for example, in case of illness or lack of vitamins, even it requires feeding.
What problems can be solved?
Grow the hydrangea in the garden or at home there may be absolutely any person, at least a little knowing the basic rules for the care of plants. And here how to make the hydrangea abundantly bloomed, did not hurt and even pleased the eyes – not everyone knows. The flower requires a regular watering and a wet soil, and in case of illness or adverse weather conditions – feeding. During the growth of the flower, a variety of problems arise, some of them are solved by feeding.
So, When dull, as if “marked” leaves with a yellowish tint, it is necessary to use fertilizers with nitrogen – It is his lack who provokes an unhealthy color of the leaves. If there is no opportunity to purchase special fertilizers, you can use the usual ammonia alcohol, which contains a large amount of ammonia and can act as a nitrogen substitute.
For this make a solution from a bucket of warm water and 2-3 tablespoons of ammonia alcohol. After that, the resulting liquid is transferred to the sprayer or a special hose, spray hydrangea from above down. If the plant is in no hurry to recover and retains pale leaves, then a similar procedure is repeated after 14 days.
Another reason for changing the color of leaves – chlorosis. This is a disease in which the plant lacks the iron. In this case, make a solution from sulfate iron and iron vigor. Each component is acquired in powder, after which they measured 7 grams of each and bred a liter of warm water. This procedure must be repeated twice – the second time the hydrangea spray after 10 days.
Nitrogen fertilizers can also be used in cases where hydrangea is growing poorly. Nitrogen forms a healthy growth of young branches and the formation of lush foliage in shrub. But be careful with the feeding of nitrogen – it is too frequent of its use can lead to an excessive set of vegetative mass (quantity and weight of leaves), which in turn will take part of the nutrient elements from buds, which means that bloom will be sluggish and weak. If the leaves are brighten, but do not yellow, but simply lose a rich green color, pale, you should pay attention to additives with nutritional components, among which the dung alive and urea must be present. Use your feeding data on instructions attached to them.
To feed the hydrangea for lush flowering in the garden can be phosphorus, potassium and magnesium.
Phosphor is responsible for how many buds will bloom on every bush, what will they be sized, how long will bloom. The greatest significance of potassium is manifested in the formation phase of buds. The more magnesium, the richer than the color of the inflorescence.
The number and variations of the compositions for fertilizers are very large, and still open new compounds that may affect the plant in one way or another. But Currently, preference is given to chemical fertilizers. A little earlier when various additives could not be bought in a specialized store, but only make it yourself, most fertilizers were organic. Some of them are still used.
Chicken litter, more precisely, chicken litter infusion is quite common fertilizer. Before use, he divorces water several times. First, the kilogram of the litter is bred by twenty liters of warm water, and after obtaining a concentrated solution, it is diluted with water again, but already in proportion 1: 3. The infusion of cow’s manure is also bred twice. The first time a kilogram of manure is poured with 10 liters of water, and then each liter of concentrate is diluted with two more liters of water.
Organic Fertilizers include kefir and other dairy products, which not only themselves are good additives, but also perform in the role of acidifiers, which is very good for hydrangea, because its growth is associated with the acidity of the soil, and the higher the acidity, the better the hydrangea is growing. A similar properties have yeast, more precisely, yeast infusion. However, when using foods, make sure that they do not have salt, as it is harmful to soil and plants. Good additive is a mangartan. In order not to burn plants, it is necessary to feed them with a pinkish infusion. Manganese makes shoots stronger and flexible, give strength, will increase the inflorescences and extends the flowering time.
As already mentioned above, hydrangea – plants that prefer to grow on acidic soil. In an alkaline environment, they can hurt a lot and practically do not absorb fertilizer. To this not happen, it is necessary to periodically acidify the soil. This can be made with a solution of citric acid, a solution of apple vinegar or a weakly acidic electrolyte solution. Additionally add in any of these solutions you can chelate iron, it is also an iron vigor. In the future, this will help avoid chlorosis.
With caution it is worth using such organic fertilizers like wood ash or a dolomite flour – these substances reduce the acidity of the soil, which leads to the fact that the plant is worse than the fertilizer, as well as the reduction in acidity can change the color of the inflorescence.
Urea refers to mineral fertilizers, so it is necessary to ensure that the plant does not accumulate surplus salt sediments. This will lead to a violation of hydrangea metabolism, the flower is sick.
If you purposefully decided to change the color of your hydrangea, this can be done by changing the acidity of the soil. To do this, it is possible to start applying alum – a solution of aluminum-potassium alum need to pour plants. This will significantly reduce the amount of acid in the soil and turn pink inflorescences into blue. Do not forget that, in its effectiveness, organic fertilizers will not be equal to specially designed compositions that already contain all the necessary components.
Industrial (chemical) fertilizers are usually more effective. Despite the fact that some gardeners have prejudices against such compositions, industrial fertilizers are very useful, as they contain all the necessary kits of trace elements. The only rule when using them – strictly follow the instructions. Varieties of industrial fertilizers are very much, we give the most useful for the growth and flowering of hydrangea: “Firth of Crystal for Hydrangees”, “Agrikola” for hydrangea. The following industrial fertilizer Bona Forte “Fertilizer for blue hydrangeas” can change the color of the inflorescence.
If you did not plan to change the color, it should be used with caution.
For each feeding there is a certain time. This is due to the fact that different elements contained in the additives are responsible for different process of hydrangea. And also upon obtaining all the necessary substances, hydrangea will be more resistant to the changeability of weather conditions, diseases, pests and other stress (for example, transplantation). Before you feed the plant, you need to remember whether you added to the well when planting plants any fertilizers. If yes, then the next couple of years, hydrangea does not need additional feeding.
In the spring it is necessary to feed the plants of those microelements that are needed for the active growth phase. These include: nitrogen, phosphorus, potassium, magnesium, iron. Nitrogen is responsible for the set of vegetative mass. The lack of phosphorus will express in the chill and inexpressive flowering. Potassium is a universal element that can be added to lures and spring, and in the fall. In the spring feeder, he is responsible for high-quality bloom. The brightness of the inflorescences and the formation of buds depends on magnesium.
The first feeding of the plant occurs when snow comes down and the first grass sprouts will be shown. This is usually happening in May or the end of April. The first feeding must consist of nitrogen-containing fertilizers. This is an ammonium nail or urea. If desired, it is possible to use organic fertilizers, but their effectiveness is much lower. Together with nitric additives, you can use potassium and phosphorus.
It happens that you forgot or missed the first feeding. There is nothing terrible in this, the main thing is to add a little more nitrogen at the second feeding. If you missed and the second feeder – this is also not a reason to be upset. Some dackets do not feed the hydrangea in general and, despite this, they grow beautifully. Fully excluding nitrogen from feeding not worth it – it is he who helps the plant in the formation of new stalks and leaves.
The second feed must be in July, during the bootonization period. Most often most gardeners make only one feeding – just when buds are formed. They immediately give the plant a full range of essential nutrients and trace elements. However, the main thing here is not to overdo it, so such things should be left more experienced gardeners.
During the second feeding, accent, on the contrary, shifts towards phosphorus and potassium, as they affect the status of buds. Nitrogen requires quite a bit, to maintain the general type of plant. Surplus nitrogen is able to lead to the fact that the vegetative mass will drag on most of the nutrients without giving buds, as it should be formed and reveal. And also an excessive amount of nitrogen will lead to the fact that the hydrangea will simply “drive the foliage”, not allowing the leaves to fully live their life cycle, forming all the time new. As a result, the leaves will become weaker, and the plant itself will begin to wake.
The feeding directly during flowering occurs at the request of the gardener to extend this period for the longest time. Accent during flowering does not change, potassium and phosphorus are considered the most necessary.
The latest feeding takes place in the fall to prepare hydrangea to the long period of wintering. Her goal is to give the plant to accumulate as much nutrients as possible so that next year the awakening and education of new kidneys occurred as soon as possible. In this regard, Potassium comes to first place, after – Phosphorus. We begin to gradually remove the nitrogen from the feeding immediately from the beginning of August and completely remove from the composition of the fall, since he is responsible for the formation of new branches that it is absolutely not useful in winter. And on the contrary, the number of potassium increases, as it is responsible for the formation of a strong root system, and the stronger and longer than the roots of the plant, the better the plant will survive the winter when the amount of nutrients in the soil is minimal.
Proportions and sketching
There are general recommendations of the fadeing of hydrangeas, on which not only the digestibility of beneficial substances depends, but also avoid possible injuries from the chemical elements contained in the additives. Before undercaming plants you need to pour in conventional water. All fertilizers, especially mineral, add only to wet soil. To prepare for the feeding need in advance – a few days before the planned subject, it is necessary to thoroughly shed the land around hydrangea. Feeding always happens either early in the morning or in the evening when the sun is already lowered. If the weather is cloudy and the scorching sun is hidden behind the clouds, the feeder can be done at any time.
Feeding are divided into extractive and root. Extra-corner feeding is, for example, spraying. It is believed that extractive feeders are most effective when the disease or lack of vitamins affects the appearance of the plant (during chlorose). But remember that even a few extractive feeding will not be able to replace one root, when all nutrients come directly to the roots of the plant, and the roots apply to the most necessary places at the moment.
It should be remembered that all feeding, including organic fertilizers, are made strictly according to the instructions. Mineral fertilizers, for example, urea and ammonia agriculture, are always bred by 10 liters of water. Urea is added 10-20 grams per 10 liters, and Selitras – 15-30 grams. In order not to breed each mineral additive separately, you can use special mineral complexes.
Mineral complexes include nitroammophos, containing phosphorus, potassium and nitrogen by 16 percent of each. This complex is also diluted with 10 liters of water, which accounts for approximately 20-30 grams of mineral additives. About five liters of this solution takes about each bush. Diammofoska is another mineral complex in which phosphorus and potassium contains 26 percent, but nitrogen is only 10 percent. Ten liters of water accounts for only 10 grams of this additive.
Next subgroup of additives – Phosphorus-potash. The greatest part of this complex falls on phosphorus and potassium, and only a small part is given under nitrogen. In this regard, this supplement is suitable for the bud of the formation and blossom of bud. These include superphosphate, in which the highest concentration of phosphorus – 2-30 percent, and only 6-9% of nitrogen. On 10 liters of water accounts for 10-20 grams of this additive.
There is also a double superphosphate, phosphorus content in which as much as 46 percent, but nitrogen is not more than 10 percent. If you decide to use a double superphosphate, the dosage should be reduced by 2 times, that is, 10 liters need to add only 5-10 grams. Potassium sulfate contains the most concentrated mixture of potassium – from 46 to 52 percent. On 10 liters of water, you need to add only 10-20 grams of sulfate. But it is best to use Kalimagnezia, which, together with potassium, contains magnesium, which is responsible for the saturated color of already discontinued buds.
If there are some problems with soil, for example, insufficient acidity leading to the problem with the assimilation of useful elements from feeding, it is recommended to use the humats. They help the plant better absorb fertilizers.
You can create a special feeding scheme, which will include a suitable complex of mineral fertilizers, then the necessary phosphorus-potassium additive (superphosphate or calmagnesis). Selected additives must be pouring the humate in the proportions specified in the instructions and carry out the root feeding with the resulting solution.
For first feeding, use potassium sulfate and urea. It will be needed on one tablespoon of each additive that must be pouring ten liters of warm water. However, this mixture is enough for only two plants, since to obtain a plant of the required amount of beneficial substances, you must spend at least five liters on watering one bush. Before bootonization and bloom, it is necessary to translate the plant to other feeders containing elements that are more suitable for that period. Any phosphorus-potash fertilizer is suitable. They are quite simple to use, as any of them is poured with 10 liters of warm water without additional dilutions and additives.
In the summer there is a preference to organic fertilizers. One of the most suitable – flavored nettles. It is great for hot summer, when it is used there is no danger to overload the soil and plant, but the concentration of nutrients in a rattage solution is several times less than that of industrial fertilizers. The infusion is made in two stages – first the concentrated solution, and immediately before irrigated – the solution, diluted in a bucket of simple water. After applying the spectal infusion it is worth shedding hydrangea to an additional bucket of clean water without additives.
During the ripening period and disclosure of buds for greater flowing duration, such feeders are used, such as, for example, “Kemira Flower”. On 10 liters of water there are only one tablespoon of this tool, so its consumption will be quite economical.
