We are talking about a genus that includes a very large number of typically climbing plants belonging to the evergreen category.
The Dipladenia genus is characterized by including a whole series of plants that are characterized by having a shrub or herbaceous development.
We are talking about species that come, in particular, from South America, or from areas in which they can even go beyond heights of ten meters.
Precisely because of this characteristic, this genus includes climbing plants that are not very suitable to be grown inside apartments or, in any case, closed places, except in the case in which you can have really abundant spaces.
The species that fall within the Dipladenia genus have numerous peculiarities especially as regards the leaves, since they have a traditional green color and are generally smooth and leathery.
No less interesting are the flowers of this genus, which are characterized by varying between pink, red and white, in relation to the species being considered.
Still on the basis of the species being analyzed, we will find Dipladenia plants that bloom during the summer season and others that, on the contrary, carry out this phase during the autumn season.
This genus includes species that, in most cases, must be cultivated within areas that are characterized by temperatures that do not drop below twelve degrees during the winter season.
In any case, they prove to be particularly resistant to heat, with an ideal summer temperature around twenty-one degrees centigrade.
During the winter season, the plants that fall into this genus have the particular characteristic of entering a period of vegetative rest and, for this reason, it is essential that they are grown in places that have temperatures of at least thirteen degrees centigrade. , otherwise you lose the opportunity to enjoy the wonderful flowering during the following spring.
In any case, these are plants that prefer all those positions in the open air and in the sun, although it is better to place them in a shady place during the hottest hours of the day and make sure to also avoid drafts. and over-ventilated areas.
During the autumn and winter season, this climbing plant must be irrigated in such a way as to keep the substrate fairly moist.
It is also essential to always guarantee the environmental humidity, which must be preserved, in fact, by operating with constant nebulization works, especially on the crown of the plant, but alternatively it can also be obtained by placing the pot inside a specially designed saucer. made, inside which a good amount of expanded clay must be inserted, which will ensure an excellent result.
It is important that the substrate is always preserved with an excellent level of humidity throughout the entire development period and, for this reason, it is even more important that this request is respected during the hottest seasons, namely spring and summer.
The repotting of Dipladenia plants must take place every two years, especially at the beginning of the spring season.
It is essential to use a soil that has a fertile substrate base, but also sand and peat and it is equally important to pay the utmost attention when placing pieces of earthenware at the base of the pot, in such a way as to allow a good drainage level and avert the danger of water stagnation.
Dipladenia includes climbing plants that can be multiplied essentially by cuttings.
This is a practice that must necessarily be carried out during the spring season, extracting branches with a length of at least seven centimeters.
It is always advisable to use a blade that is as sharp as possible, in such a way as to extract perfect branches, which do not have frayed tissues and which are therefore not possible carriers of diseases or parasites.
Following the removal of the leaves from the cutting, it will be necessary to operate with rhizogenic hormones on the surface of the plant, in such a way as to allow better rooting and then the cutting must be inserted inside a special multiplication container or in a vase.
The most important dangers derive from the attack of mites, in particular the red spider, and from scale insects.
In the first case, it is a mite that must be effectively countered immediately, since if it has some time available, it can do a large number of damage to the plant.
It is advisable to favor the increase of humidity in the environment surrounding the climber, but in the most serious cases it is possible to use the appropriate acaricides.
As for the scale insects, it is easy for them to strike above all the axillary part of the leaves and must be removed immediately, perhaps using a particular insecticide.
Do you want a flowered and colorful balcony? Dipladenia, an evergreen climbing plant from South America, can represent the optimal solution to give color and liveliness to your terrace. This plant has the ability to bloom throughout the warm season showing its beautiful bell flowers red, white or pink accompanied by the bright green color of its leaves and therefore represents the winning choice to reinvigorate your balcony. Another peculiar feature is its ability to develop quickly, in this way your flowered terrace will be the envy of all the neighbors. A further point in your favor is the ease of cultivation of the plant: it does not require particular care and attention. This is why it is also suitable for those who do not have a particular green thumb!
There are four main species of Dipladenia, mainly used for decorative purposes:
1) Dipladenia boliviensis (also known as Mandevilla boliviensis). As the name suggests, the plant is native to Bolivia (but can also be found in Ecuador). It is a climber with a woody and very branched stem. Its leaves are long, tapered and shiny while the flowers are rather small (not exceeding 5 cm in length), with a white color and a throat that tends to yellow-orange.
2) Dipladenia splendens (also known as Mandevilla splendens). It is always a very vigorous climber that produces splendid inflorescences of a deep pink color. The flowers can last 3 to 4 days.
3) Dipladenia sanderi (also known as Mandevilla sanderi). The origin of this variety is Brazilian and has rather pointed oval leaves and an intense green color. Its pink flowers are very large and beautiful.
4) Dipladenia laxa (also known as Mandevilla suaveolens). More commonly known as Chilean jasmine, it has white tubular flowers. This is also a rather vigorous climber.
