Hydrangea - flowering plants of the Hydrangea family.
It is grown as a garden and home plant, moreover, in the second case, it is only large-leaved.
Hydrangea in open ground can grow up to 4 m, in room conditions - up to 1.5 m. Its leaf plates are simple and ovoid, painted in bright green.
Flowers gather in shields 10-15 cm. Pink ethereal flowers 3 cm in size are located on the edges. Some types of inflorescences have up to 20 cm. Their color can be pink, white, and also blue.

Planting room hydrangea
Indoor hydrangea usually lives for about four years.
In addition, it should be transplanted annually, because it is growing and requires more space for itself. The pot for this should not be too deep. The main thing is that it should be wide, due to the fact that the roots of this flower grow in breadth. Each new container should be approximately 1.5 times larger than the previous one.
Large and beautiful hydrangea can be obtained by growing it in a suitable soil, take in the ratio (0.5: 1: 1: 2):
- sheet earth;
Compost can not be added, because it negatively affects the root system of the flower.
Indoor hydrangea experiences stress from transplantation, which affects its development in the future. To help survive this event as best as possible, you need to use the transshipment method. A sufficient amount of drainage must be placed on the bottom of the pot into which the plant will be placed. After that - place the flower in a flowerpot and then fill up all the free space with a fresh substrate. It should turn out that the root neck of the hydrangea will be at the same level with the ground surface.
After that, you need to moisten the soil and pour a little peat mulch on top. This helps maintain sufficient moisture in the soil.
Hydrangea care at home: table
Indoor hydrangea does not like bright light, its flowers fade from the sun and spots appear on them. Therefore, it is better to place it on the western or eastern windows. In summer, it is good to make it onto the balcony, terrace, and garden.
|Temperature||+ 17 ... +22 ° C.||+ 9 ... +12 ° C.||+ 5 ... +8 ° C.|
|Irrigation, water acidity||Once or twice a month, acidified with water, adding 5 drops of lemon juice or a pinch of its acid per 1 liter of liquid.||Once or twice a month, acidifying the water.||Only after drying of the soil, acidification is not necessary.|
|Humidity||50-60%. In the morning you need to spray with soft water.||Not lower than 50%.||Low|
|Top dressing||A couple of times a month with conventional fertilizers for hydrangeas.||Do not use.|
It is very interesting that this flower is unique in its ability to change the color of flowers due to the varying acidity of the soil. Many try to experiment in this area.
For example, when there is a lot of limestone, the petals are painted in pink, and aluminum - in blue. The increased acidity of the soil allows for high brightness and vice versa.
There are two ways to propagate hydrangeas: seeds and cuttings.
With seed, it is necessary to sow them in the fall. Then do the following:
- Prepare the soil. To do this, mix sheet and peat soil with sand (4: 2: 1).
- Place the seed in the substrate, sprinkle the soil on top and moisten.
- Cover the pot with foil. Sometimes it is necessary to remove it - this allows the soil to ventilate.
- The temperature must be between +14 ° C ... +20 ° C.
- When sprouts appear, you can remove the film.
- When two or three true leaves grow, you need to transplant to another place.
Cuttings occur in the winter. In this case, you need:
- Make a few cuttings and cut their slices with Kornevin.
- Plant in moist peaty sandy soil. To a depth of about 3 cm.
- Cover with something (for example, a film). It should be a mini-greenhouse.
- Make sure that the temperature is about +20 ° C, and the humidity is about 80%.
- From time to time, the plant should be ventilated and sprayed.
- When the roots appear (this takes about a month), seedlings must be transplanted into other pots.
Some use another way - layering.
To propagate it like this, you need a huge spacious pot. The process itself is as follows:
- Choose the largest branch.
- It is slightly incised and bent to the soil, while sprinkled on top of the ground.
- The soil is kept moist.
Thus, the shoot will have roots. After that, it is separated and placed in a separate pot.
Protection against diseases and pests
Manifestations on the leaves
|Flowers and shoots wilted.||The root system received too much moisture and because of this, pests gnawing the root appeared in the ground.||Immediately transplant a flower. First, check the root system for rot, if any, remove. Then treat with any fungicide. Dry the roots and after transplantation do not water the plant for a while.|
|Yellowed and began to fall.||There is too much lime and little iron in the soil. Also, a very bright light can be the reason.||Protect from bright light. The main thing is to measure the acidity level of the soil. If it exceeds 8 pH, urgent soil change is required. Remember that watering should be done with clean soft water.|
|Dried from the edges.||Needs moisture.||Water in a timely manner and in the morning spray with boiled water.|
|The appearance of spots and plaque.||Fungal disease. Powdery Mildew||Treat with fungicidal preparations three times a week. Keep track of temperature, watering, humidity and lighting. Fertilize.|
|Does not bloom.||Missed winter dormancy. The temperature regime is increased.||Place in a shaded, cool place.|
|The pot is too wide.||Move to a container suitable for the roots.|
|The trunk turned black below.||The flower suffers from a black leg. This disease appears from abundant moisture and low temperature.||Check the flower for pristine roots. If they are present, there is a chance of salvation. Cut some healthy cuttings. After - replace the soil. Perform treatment with Fitosporin and an immunostimulant. You can also treat Trichopolum several times a week.|
|The shoots dry and break.||The roots are overdried.||Several times it is necessary to shed the earth, as well as cut dried shoots. It is important to remember regular watering and spraying.|
|There were growths, fluff and cobwebs.||Pests. Growths are scabies, down is a mealybug, and cobwebs are a tick.||Treat the flower with a pesticide (they must first be removed).|
|Many holes, buds fade, and then fall off.||Weevils and aphids.||Spray by any means against pests.|
|Traces of microworms are visible.||Nematodes infected the soil.||Treat the soil and leaves with Nematofagin. It is best to replace the soil.|
|There are multi-colored circles. Also change shape.||Viral disease.||Remove damaged parts of the plant. For two months, treat several times a week with the composition: Phytolavine at the end of a teaspoon + eight drops of Epina + dose Extra Flor No. 1 + Boric acid at the tip of a knife per liter of water.|
