Dipladenia cutting (Manduca sexta) is one of the most popular and widely grown plants in the world. It grows naturally in tropical regions such as South America, Africa, Asia and Australia. The species name means “two-faced” because it produces two different types of leaves: small, delicate ones called cotyledons; and large, tough leaves known as petioles or leaflets.
The plant’s native range extends from southern Brazil to northern Argentina and Paraguay. It was introduced into North America in the early 1900s, where it became common throughout Florida and other parts of the southeastern United States. Today, it is found throughout much of the eastern half of the country, especially New York City and Boston.
It is also commonly cultivated in Mexico and Central America.
How To Grow Mandevilla Plant?
Mandrake (or mandarin) tree, which is native to South America, is often confused with mandevilla. However, they are not related at all. Mandevilla plant can grow up to 20 feet tall and wide and its flowers bloom only once every few years. They have no roots but produce their fruits when cut off the stem so they do not need support from above or below.
The mandrake plant is considered a bit of a weed and often considered ugly by some people. It has a fast growth rate and can get out of control if not properly controlled. Its flowers are white or greenish-white and have an unpleasant odor.
They also produce a toxic sap that can cause skin irritation, so it is important to wash your hands after touching it.
Mandevilla can grow up to 20 feet tall and wide. They bloom only every few years and its flowers have no roots but produce fruits when cut off the stem do not need support from above or below.
Mandrake should be planted in relatively large pots around 15 inches wide and half-drained soil. This is done when you plant, do not water and wait to dry the soil.
How To Propagate Mandevilla Cutting?
The mandevilla cutting should be about 8 inches long with a couple pairs of leaves. It is best to take cuttings from plants that are at least a few years old, rather than new plants. New plants may grow roots, but they may not survive for long after transplanting.
The cutting should be at least as long as the new roots are likely to be so that it can hold itself up. Cutting with a thicker stem can also allow you to insert a stake for support. The bottom of the cutting should not be allowed to sit directly on the soil; having it float in a small glass jar partially full of water can ensure that only the new roots are touching the water, preventing rotting of the stem.
The root hormone can be applied to the cut end and a small weight can be tied to the top to keep it below the water line. This will ensure that all of the energy goes toward making roots rather than trying to lift the cutting upward.
Patience is required when rooting mandevilla cuttings because they can take up to three months to grow roots.
How To Care For The Mandevilla?
Once the roots of the mandevilla cutting have grown sufficiently, it can be transplanted into a pot or directly outside. If the new plant is being put into a pot, any ordinary potting mix should be suitable as long as it drains well. If it does not seem like the roots are growing, then you can add a bit more perlite or sand to the mix to improve drainage. Keep the soil moist but not soggy and place the pot in a partially sunny location.
If you wish to directly plant your mandevilla cutting outside, it is best to wait until at least the danger of frost has passed in your area and the soil temperature is at least 60 degrees Fahrenheit. Mandevilla can be planted either directly into the ground or in a pot. If planting it directly into the ground, any well-draining soil will suffice.
If you wish to plant your mandevilla in a pot, the same potting mix described above should be used. Place the pot in a location that receives at least four hours of sunlight each day and keep the soil moist.
Your mandevilla will begin to grow leaves and eventually flowers. Each year as the plant grows, you should prune it back by about a third to keep it under control. This can be done anytime from spring until early summer as this plant is resistant to dieback.
It should be placed in a sunny location and the soil kept moist but not soggy.
