Hydrangea (Hydrángea) - a beautifully flowering shrub with large glossy leaves and spherical inflorescences of various colors. Any garden in which this plant settled acquires special charming features. Few people think that hydrangea can be grown at home, that is, in a room. In modern interior design, this flower has gained unprecedented fame for a modest and at the same time very decorative element.
Using plants in the interior
The main role of hydrangea grown at home directly on the windowsill is nostalgic. Any room where such a flower grows is filled with unique coziness, almost like that of a grandmother in early childhood. Nevertheless, the plant is considered fashionable and modern and is used to give the interior freshness.
The most organic hydrangea looks on the background of light walls in pastel colors, as well as surrounded by laconic furniture. The plant always manages to organically solo, regardless of the design of the room, whether it’s a hi-tech or fusion style. It is important to remember that the indoor flower looks better away from exotic plants with spotty leaves and spreading crowns.
This flower shows the greatest decorativeness if grown in a pot of an unusual shape: a sculpted ceramic bowl or in a bowl-shaped container, for example. Particularly beautiful are the group compositions, which are a mix of multi-colored varieties of hydrangeas, which are planted in a classic ceramic pot or a spacious planter. In a word, everything unusual and at the same time faded in colors can safely side by side with this incredibly beautiful shrub.
How to grow hydrangea in a pot
The best varieties for indoor cultivation
There are dozens of varieties of hydrangeas that have already conquered the garden, but not all of them are able to successfully grow and bloom in a room or on a balcony. In recent years, amateur gardeners and professionals have identified a group of varieties that can be safely recommended for cultivation at home. These include:
|Grade name||Plant description||Flower and flowering features|
|Compact||Low-growing shrub with lush foliage and bright color of leaf blades||Inflorescences are spherical, depending on the growing conditions and soil composition, this hydrangea is white or pink|
|Madame E. Muyer||The bush is compact, aligned, spherical in shape. Leaf blades bright, glossy, slightly narrowed compared to other grades||The flowers are collected in white balls. Inflorescences are very dense, hold for a long time|
|Europa||Medium thick dense bush with large leaf blades||Unique light blue flowers, very decorative|
|Souer tharese||A short, compact plant with a spherical shape of a bush. Leaf blades small, bright||White flowers, aligned, regular shape|
|Red sensation||Spreading and at the same time fairly dense spherical bush, glossy leaf blades, saturated green||Inflorescences are red during classical cultivation, and when alum is added to the soil, they change color to burgundy or violet|
|Ramars mars||Compact medium-sized bushes with emerald leaves||Inflorescences are spherical, consist of pink flowers with a white border. Over time, this white rim takes on a greenish tint.|
|Airlie blue||Tall bushes with dense foliage||The flowers are bright blue, collected in very dense inflorescences-balls|
|Goliath||Tall, large shrub, completely covered with glossy dark green leaves||Deep pink flowers collected in inflorescences spheres|
Room growing conditions
Indoor hydrangea cultivation is not easy, as this crop needs a resting period, which should last at least 60 days. At this time, she needs cooler air, and the soil in the pot should not be moistened. During the rest, hydrangea is best kept in a cool dark place - on the balcony or in the basement. It is important to remember that without wintering the plant will not enter flowering. The rest of the time, hydrangea needs an abundance of light and fresh air, as well as a sufficient amount of high-quality soil for normal growth and development of the root system and, as a result, beautiful long-term flowering.
The room and the garden are somewhat different in temperature and other conditions, so when growing indoors, it is important to pay special attention to the care of the potted culture. Illumination, soil and air humidity, nutrient content in the substrate - all this must be taken into account and meet certain standards. Despite the presence of a dormant period, room hydrangea will have to be taken care of throughout the year.
The soil substrate for potted hydrangea should have an acid reaction, for which it includes:
- turf or garden land - 2 parts;
- black peat - 1 part;
- sheet land or well-rotted manure / compost - 1 part;
- coarse river sand - 0.5 parts.
Also, the flower can be planted in the purchased soil for azaleas, conifers or citrus plants.
An ideal place for room hydrangea is a window facing the southeast side or south. This plant is very fond of light! However, hydrangea does not tolerate direct sunlight. To avoid rapid fading and especially sunburn, it is recommended to slightly shade it. It is enough to place a grid between the glass and the pot, or place the pots on the windowsill, and not on it.
In summer, the best place for a plant is a loggia or balcony overlooking the west or east side. In the southern orientation, the flower also needs to be tinted.
Soil and air humidity
Proper care of hydrangea consists in regular abundant watering, especially during flowering. It is important to prepare water in advance, defending it during the day. Occasionally, it is recommended to water the flower with slightly acidified citric or oxalic acid water. To eliminate the risk of waterlogging, it is recommended to arrange a drainage in the pot.
Air humidity is also important. It is necessary to spray the plant daily with settled, not cold water. During flowering, water containers or fountains can be placed next to the pots.
It is necessary to make top dressing in pots twice or thrice a month, depending on the activity of growth and flowering. In this case, it is important to choose the right season for top dressing - it must coincide with the formation of the first inflorescences (before they bloom, at the stage of budding).
During the flowering period, the best fertilizer is considered a universal fertilizer for flowering plants. Before retiring, it is recommended to feed the flower with phosphorus-potassium complexes.
For annual flowering, it is important to form a bush correctly, leaving several last year's and young shoots on it. Pruning hydrangea is carried out before the wintering of the plant or immediately after it. Last year's shoots (pruning for 2-3 internodes) are subject to shortening. Weak or emaciated stems are cut completely.
Among the young shoots, the strongest are left, thus normalizing the number of inflorescences. After flowering near the root neck of hydrangea, it is recommended to pluck the shoots, leaving the 5-6 most powerful ones.
Reproduction and transplant timing
Hydrangea is very easy to propagate by cuttings. The planting material for this is green cuttings, cut during the formation of the plant or in the summer, during the active growth of shoots. They can only be rooted in an acidic peat substrate. The survival rate is at least 80%.
Cuttings are cut to a length of 10 cm and process their lower section with a root stimulant. Then the seedlings are placed in an improvised greenhouse - a pot filled with an acidic substrate and covered with glass or film (a cap from a glass or a glass jar is also suitable). Periodically, the greenhouse needs to be aired, and after 2 months the shelter can be removed permanently. Roots appear within 4-5 weeks.
Landing and transplant dates
For room hydrangea, spring planting and transplanting is recommended. Wintered flowers are moved to a new pot in the last days of wintering the plant. To do this, choose a more spacious pot or use the old one (only if the grower regulates the growth force of hydrangea). The roots of the plant are rejuvenated, cutting off all the thin and weak, and the soil is changed to fresh in full.
Diseases and pests of hydrangea
Diseases and pests in the flower are few in number, however, they can threaten the viability of the plant and even lead to its death. Most often, the flower is affected by fungal diseases and spider mites. To get rid of them, it is recommended to take the following measures:
|Disease / pest||Signs of defeat||Control measures|
|Spider mite||Thin spider web on the underside of leaf blades, the appearance of whitish dots on them, complete drying of the ground part||Leaf treatment with Fitoverm and other insecticides|
|Gray rot||Wet spots on leaf blades that become covered with fluff over time||Reduced watering, removal of affected leaves, tillage and plants Bordeaux mixture|
|Powdery mildew||Leaves are covered with a whitish-gray coating.||Destruction of the affected leaves and shoots, with mass destruction of plants - their complete destruction|
