Pelargonium ( Pelargonium) belongs to the family of geranium. Another, more familiar name for this flower is geranium. Maybe you will be surprised, but the birthplace of this sweet and such familiar to all of us since childhood is South Africa. That pelargonium, which we all know, appeared in Holland in the 16th century, and to Europe it came in the late 17th - early 18th centuries. At first it was considered an exotic flower, but very soon, already in the XVIII century, it became incredibly popular.
As a result of the large subsequent selection work on breeding of numerous hybrids and varieties, this genus was replenished with variegated and dwarf forms, and also varieties with white, bicolour and double flowers. Today there are about 280 species of annual and perennial pelargonium, having the appearance of grassy plants, half-shrubs and shrubs.
Love for these flowers all over the world is due to their unpretentiousness, ease of care and reproduction and the ability to long blossom large colorfulinflorescences. As we have already said, the varieties of pelargonium are very numerous. They can belong to one of 6 groups: zonal( garden);ivy( ampelnym);English large-color( royal or domestic);variegated;fragrant;succulent.
The last three groups are interesting, first of all, their leaves;large-colored geranium can be grown only in the room;but the purpose of the zonal and ivy pelargonium, which can be propagated by seeds, is the ornamentation of the garden and the balcony.
Pelargonium - cultivation and care
This flower loves warmth and light. The optimal mode for its growing at home is room temperature, in winter it feels best at a temperature of 8 ° C to 10 ° C.
If there is a lack of lighting, the plant reduces its flowering. However, the direct sun rays are well tolerated by the flower in the open air, but in a room dilution it is better to pritenyat from the hot midday sun. Also, pelargonium likes free space, so you need to make sure that it is not muffled by nearby plants.
Watering should be abundant, as the soil dries up, which can not be waterlogged so as not to flood the root system. In winter, watering should be reduced. Spray the plant is not necessary, it can damage the petals of the flowers. In general, when you care for it, it is better not to add water, it will be easier to cope with this than with excess moisture.
The flower grows best in a nutritive soil mix prepared from peat and peat land taken in equal parts, peat and sand. It is necessary to take care of good drainage, and periodic soil loosening in pots should be performed to ensure air access to the roots and to prevent rotting of the roots.
When growing Pelargonium, the size of the pot is very important. It is selected in accordance with the size of the root system. But we must remember that it blooms best in small pots, then it has flowers and flowers that are more beautiful and brighter. Spacious pots contribute to the development of the bush and a lower intensity of flowering.
To strengthen the branching and formation of the bush and the crown, the plants are pricked, at which the growth point is removed. This must be done in February or March.
The flower gratefully responds to the dressing. In the period of active growth, it should be mineral mixtures or liquid fertilizers, during flowering - fertilizers with a high content of phosphorus and potassium and less nitrogen. Top-dressing is done every week from late spring to early autumn.
Pelargonium - transplant and propagation
Young plants require an annual transplant or at least a replacement of the upper layer of the earth. For transplantation take a small capacity, otherwise there will be a strong development of shoots, but the plant will not bloom. Transplant it into a mixture of turf, leaf, humus( two parts) and sand( one part).
Pelargonium can be grown from seeds and cuttings. In the first case, plants are obtained that bloom more abundantly than those grown from cuttings. Seed sowing is carried out in January-February, laying them on wet ground and slightly covering with soil for seedlings. After sprinkling with a growth stimulator, the container with seeds is covered with glass or a film and kept at a temperature of 20 to 24 degrees, periodically moisturizing. After emergence of sprouts( in 1-2 weeks) seedlings are dived and grown at a temperature of 16 to 18 degrees with good lighting for about 6-8 weeks, after which they are transplanted into a permanent pot.
However, more often the flower is propagated by cuttings, this method is simpler and faster than the first one. The rooting of the cuttings is carried out in February-March and in July-August by cutting off the apical shoot for rooting, which has 2-3 leaves and a length of 5-7 cm. Giving cuttings in the shade for about 24 hours and dipping them in crushed coal, they are put in a light mixture andcontain at a temperature of 20 to 22 degrees. Do not cover the cuttings. Rooting this way takes about a month.
Pelargonium - possible diseases and pests
If you make mistakes in the care of the plant, it will necessarily affect its appearance.
So, with a lack of moisture or its excess, the leaves turn yellow and fall off. If the edges of the leaves turn red, then the plant is freezing, it lacks heat, the leaves fall off, which means that it does not reach the light. If the soil is waterlogged, watery soft pads may appear on the leaves.
Geranium can suffer from a disease such as a black leg, in which the blackening of the base of the stem occurs due to a fungus attack. This can happen due to overmoistening of the soil or its compaction, which prevents drainage. Preventing this disease is the sterilization of the soil before planting and adherence to the irrigation regime.
Also, because of the waterlogging of the soil, pelargonium can be affected by gray rot. On the leaves in this case, gray mold appears. In this case, remove the affected leaves and treat the plant with a systemic fungicide, reduce watering, and ventilate the room more often.
As you can see, care for pelargonium is not complicated at all. Observing the simple rules of its breeding, you can get beautiful plants that will delight you not only with beautiful colorful flowers, but also with their useful properties, creating a positive and calm aura in the room.
