The plant Streptocarpus is a member of the family Gesneriae. This genus includes more than 130 species. In nature, this plant can be found on the territory of Asia and Africa. This genus is represented by shrubs and herbaceous plants, which, depending on the species can be both annuals and perennials. Cultivated at home streptocarpus began since the first half of the 19 century.
This plant is rosellate, with its stem short. Shape strongly pubescent leaf plates broadly-lanceolate, their color can be green or mottled. Flowers sprouting from the leaf axils may be singular or in bunches of two. This plant was named streptocarpus because of its fruits, as their shape is similar to a spiral long capsule. Flowering begins in the spring and ends in the fall.
The flower has a short dormancy period in winter, but the bush does not shed its leaves.
Brief description of cultivation
- Flowering. Starts in spring and ends in fall.
- Brightness. Light is needed bright but diffused.
- Temperature. During the spring-summer period the temperature should be at least 20 degrees and no more than 25 degrees. Beginning in October, the temperature should be gradually reduced to 15 degrees.
- Watering. Throughout the growing season, water streptocarpus systematically and moderately.
From October, watering should be reduced, and in winter it should be sparing, but care should be taken to ensure that the lump of soil in the pot does not dry out completely.
- Humidity of the air. Moderate.
- Fertilizer. During intensive growth, the bush is fertilized once every 7 days, and a complex mineral fertilizer is used.
- Dormant period. From the first days of October to February.
- Repotting. Transplant shrubs in the first weeks of spring: young shrubs once a year and adults once every 3 to 4 years.
Ready-made substrate for senpolias. Or you can take an earth mixture consisting of sand, humus, leaf and sod soil (1:1:2:3). If the bush is young, leafy soil is taken instead of sod.
- Spreading. By leaf cuttings, bush division, and by seed.
- Pests. Scabies, thrips, whiteflies, mealybugs, and spider mites.
- Diseases. Gray rot.
Care and propagation
Home care for streptocarpus
When growing streptocarpus in room conditions it must be provided with bright but diffused light. Therefore, western or eastern oriented windows are ideal for this flower. If you put it on the southern window, the direct rays of the sun will need to necessarily scatter. And a northern window sill is not suitable for such a plant, as the lack of light is extremely negative for its growth, development and flowering.
In spring, summer and early autumn, the room should not be colder than 20 degrees and hotter - 25 degrees.
From the first days of October the temperature should be lowered gradually, taking into account that it should not be less than 15 degrees Celsius. The best air temperature for wintering streptocarpus is 15 degrees.
In the spring and summer, the flower is watered systematically and moderately, with the need to ensure that the lump of soil in the pot is not long dry. From the first days of October watering is reduced, and in winter it should be sparingly, and try to make sure that the substrate in the pot does not dry out, and it should not be observed stagnant water. Water well drained (at least 24 hours), at room temperature.
If the humidity in the room is too low, the leaf tips of the plant will start to dry out. They must be trimmed in good time with a sharp knife and a board must be put under the leaf.
Fertilizer is given 3 or 4 times a month throughout the growing season, using a complex mineral fertilizer.
Young bushes need a regular transplant, which should be done once a year. Mature specimens are transplanted less frequently, more precisely once every 3 or 4 years.
This procedure is carried out in the first weeks of spring in wide, low pots that are filled with a mixture of leaf and sod soil and sand (4:1:2). Even for transplanting you can use a substrate consisting of sand, humus, sod and foliage soil (1:1:3:2). Store substrate for senfolias can be used for this purpose. To avoid overwatering the substrate, it should be poured into a small amount of fine charcoal. If you are transplanting a young plant, you should exclude turf from the potting soil.
Sharing a bush
Reproducing a strongly growing streptocarpus by shrub division. First, the substrate in the pot is watered with a small amount of water, then the bush is taken out of the container, and the remains of the soil mixture are removed from the root system. Then a sharp tool is taken, with which a part of the thick root with foliage is separated. Leave the divisions for some time in the fresh air, so that the cut places dry up well, then they should be treated with charcoal powder. The prepared pot is 2/3 filled with fresh substrate, then the cut rosette is placed in it and covered with soil to the level of the root neck.
Next, the substrate should be slightly compacted, and the bush should be watered with lukewarm water. In order to make the division better take root, the pot is covered with cellophane from above. Also accelerate rooting and activate the growth of young leaves can be shortened by halving the large leaf plates or they can be cut at all. A little time later, the bush produced from the dividers will begin to flower.
Growing from seed
Sow the seeds in a small container and distribute them evenly over the surface of the substrate.
Then cover the container with glass from above. Seeds need bottom watering through the tray, also they need to provide systematic ventilation, lighting should be bright but scattered, and the air temperature should be constantly about 21 degrees. To ensure that the temperature does not drop, you need to put a paper sheet on top of the glass. However, it is better to keep the crops not on the windowsill, but under the lamps. After 6 weeks, the cover should be moved slightly, and then it is removed completely.
For the first picking of seedlings use a container, which should be slightly larger than the old one, and the distance between them should be increased only slightly. In order to seedlings during the picking not to severely traumatize them, transplant them carefully. To start with a light knock on the walls of the container, then planting carefully prying needle and holding the leaves with your fingers, transplanted into a new container. The substrate is slightly compacted, then transplanted seedlings are watered, and then the container is placed on a pallet and moved to a warm place, with the top of it covered with glass or film. For the second picking use individual pots.
For the plants to develop better, it is recommended to feed them.
Seeds can be sown several times a year, and this can be done at any time of the year. This will allow you to obtain bushes that will flower at different times.
A young leaf plate that is well developed and absolutely healthy (no signs of disease or pests) should be cut off from the bush and then the petiole should be trimmed with a sharp blade. After the cuts have dried, the leaf petiole should be planted in a small pot, placing it vertically.
Then it is sprayed with a solution of a fungicidal drug, and the container is covered with a film on top. After that, the pot is removed to a well-lit and warm place. After 4-6 weeks, young shoots should appear. After the plant grows a little older and stronger, it should be transplanted into a permanent pot. If the cultivated bushes of streptocarpus of different species, it is recommended to stick labels with the name of the variety on the pots.
For multiplication, you can also use part of the leaf plate. To do this, the leaf is laid face down on a board, then using a sharp blade it is cut into strips, which should be 50 mm wide. Cut the sheet plate should be perpendicular to the middle vein. The lowest and the uppermost part of the leaf plate should be thrown out, and the remaining pieces should be planted in the grooves with the base of the cutter down at an angle of 45 degrees. The distance between the cuttings should be at least 30 mm.
They should be sprayed with a solution of fungicidal drug, then the container from above is covered with a transparent bag and removed to a humid place where the air temperature should be 20 to 22 degrees. Water the cuttings through the tray, and they also need daily ventilation. Young shoots will appear from under the ground after 6-8 weeks.
A longitudinal part of the leaf plate can also be used for propagation. To do this, the leaf is placed face down on a board and then the middle vein is separated with a sharp blade.
In the resulting two parts of the leaf plate, the cut places should be sprinkled with carbon powder. After that, they are planted in grooves with the cut vertically downward, deepening them to 1/3 of the height of the leaf petiole, then the substrate is slightly compacted, then it is watered, and the container is covered with a film from above. The container is moved to a well-lit and warm place. Young plants will appear along the entire leaf plate from the lateral veins. On the underside of the plate, twenty-millimeter incisions should be made on the middle vein every 2 cm.
Then the leaf cuttings are pinned to the surface of the moistened substrate, and then it is sprayed with a fungicide. The container with the cuttings should be covered with glass, and then it is transferred to a well-lit place, protected from direct sunlight. After the young shoots appear, the cover should be moved a little.
When the grown and stronger bushes are transplanted into individual pots, they should be covered for the first few days with a transparent polyethylene bag. After removing the cover, the plants are cared for in the same way as mature specimens.
Propagation of Streptocarpus foliage at home part 1
- Gray rot rot. If streptocarpus is watered excessively, it can be affected by gray rot.
- Boots turn brown. This occurs when the room temperature is excessively high.
- The edge of the leaf plates turns brown.
This can occur due to stagnant liquid in the substrate or if the room has excessively low humidity.
- Pest insects. Thrips, spider mites, scales, whiteflies and mealybugs most often settle on such a flower.
The problems of streptocarpus are non-infectious. Wasting.
