Mandevilla was attributed by scientists to evergreen shrubs from the Kutrovy family. The homeland of Mandevilla is the tropics in the territories of North and South America. The flower got its name in honor of the famous British diplomat and gardener G. Mandevilla.
The very first species that were found by botanists in Central and South America were named differently – Dipladenia. But a little later, British scientists discovered another species of the same plant. And he has already been named Mandevilla. But after a while, scientists agreed on a common opinion that these two differently named plants are representatives of the same genus. And it was decided not to change them, but to leave their own for each.
The leaves of the shrub are more egg-shaped, glossy, green or dark green, from 3 to 9 cm long. The flowers have a special unique aroma, pink, red or white shades. It blooms profusely, each flower can reach a diameter of about 10 cm.
Caring for Mandevilla at home
Location and lighting
The homeland of Mandevilla’s origin suggests bright lighting for the plant. The flower tolerates direct sunlight well, but in order to avoid burns in the open sun, it is better not to leave or shade for a long time.
The optimum temperature in the room for growing Mandevilla in spring and summer should be in the range of 23 to 25 degrees, and in winter, with the onset of a dormant period, at the level of 12-15 degrees.
Mandevilla prefers to grow in rooms with high (about 70%) humidity, so it needs to be sprayed regularly throughout the day. In winter, the plant also needs to be sprayed, especially if it is located near heating appliances.
In the spring and summer months, Mandevilla needs abundant watering. As soon as the top layer of the substrate in the container dries up, watering must be done again. With the onset of the autumn-winter cold season, there is practically no need to water the plant. In winter, the soil is moistened only when the potted substrate is completely dry. Water for irrigation should be soft at room temperature or slightly higher. For 1 liter of water, you can add a little citric acid (about the tip of a knife).
The soil for a Mandevilla must be nutritious. The optimal composition of the soil: clay-sod land, leafy soil, humus and sand in a ratio of 2: 1: 1: 1. A generous drainage layer is laid at the bottom of the pot.
Topdressing and fertilizers
Fertilizing the soil should be frequent – about 3 times a month from March to September. You can use a universal fertilizer for flowering houseplants. For the rest of the time, they stop feeding the flower.
If the plant is young, then it must be transplanted every year in the spring. An adult plant is transplanted only when the root system is already cramped in the pot.
Since only young shoots from above bloom in Mandevilla, it is necessary to prune the plant in late October-early November. Unbranched shoots are shortened by about 2/3 of their length. Thanks to pruning next season, Mandevilla will delight you with lush blooms.
Reproduction of Mandevilla
Mandevilla is usually propagated by cuttings-shoots about 8-10 cm long. Cuttings are planted in peat and covered with a transparent film and kept at a temperature of 25 degrees. Cuttings take root in a greenhouse for about 1-1.5 months. After the first roots appear, the film must be removed. After about 3 months, the young plant is transplanted into a separate pot.
Diseases and pests
Rarely, but leaf pests are found on Mandevilla. More often the plant suffers from damage to the root system. Nematodes or root mealybugs can harm her. These parasites are transferred with the substrate during transplantation. Therefore, before planting a plant, the ground must be calcined.
Root rot is among the bacterial diseases affecting Mandevilla. Its appearance is the result of improper care and overly moist soil.
- If Mandevilla leaves have turned yellow and fallen off, then it indicates that the ambient temperature is unsuitable for her.
- In insufficient light, the flowering of the plant will be short-lived and low-flowered.
- With dry indoor air, the leaves will be pale and lethargic and will soon crumble.
- With the insufficient application of minerals and trace elements to the soil, Mandevilla will develop poorly and grow slowly.
