What Is Mandevilla Sanderi?
Mandevilla Sanderi, also known as Jasmine Vine, Sander’s Jasmine, Brazilian Rose, or Brazilian jasmine, is a climbing plant with a very slender stem and delicate bracts along the flower stems. It is also known as Sander’s jasmine and Jesmonium. The species name “Sanderi” honors the Dutch botanist Jacobus Sander (1695-1730).
It can be cultivated in the sun or part shade. Mandevilla sanderi are usually grown in pots during winter to keep them growing during the dead season. The plant has a moderate growth rate, spreading slowly to cover a wide area.
The plant prefers to climb up a trellis and is also very suitable for growing independently. It would grow in a pot as well as in the ground but generally prefers the latter. No known pests or diseases affect this plant, but the plants should be kept dry during the wintertime.
During summer, the plants like to get 2-5 hours of direct sunlight. Water regularly with regular water and keep it at soil level during summertime. Mandevilla vines require sandy, well-draining soil that is rich in organic matter.
A decent potting mix includes peat moss, sand, and leaf mold. The plant prefers slightly acidic to neutral soil pH, although it may also survive slightly alkaline soil.
Weekly, immerse your plant with water until you observe damp soil or water draining from container plants. Maintain a moist but not dripping wet soil that drains well; reduce watering throughout the winter when growth slows, allowing the soil to dry out more between watering.
Use a controlled-release fertilizer at the prescribed rate twice a year, in the spring and late summer. Use a liquid or water-soluble bloom booster fertilizer at maximum strength every 4-6 weeks from mid-spring to mid-summer to maintain your plant blossoming effectively.
Mandevilla Sanderi or Jesmonium requires very light pruning that does not interfere with the plant’s shape or affect its growth. The plant grows slowly but can grow much more quickly if you follow the same principles described below.
The pruning method is based on natural growth principles, allowing the plant to grow along with its branches. The main goal is to remove dead stems and replace them with new ones. The old stems are unsuitable for propagation because they are brittle and weak. They have too few leaves and only small flower buds.
Pruning a Mandevilla Sanderi should be done during summertime when the plant is actively growing. When you are pruning, try not to damage any leaves or flowers because this will cause the plant to lose a lot of sap that it needs for growth, slowing its growth rate during autumn and winter.
How Do You Care For A Mandevilla Sanderi?
Mandevilla Sanderi is not difficult to care for and does not requires a lot of maintenance. Mandevilla Sanderi requires full light to blossom properly. They can, however, withstand mild shade. Give your Mandevilla Sanderi plant a high phosphorus, water-soluble fertilizer once every two weeks to receive the greatest Mandevilla Sanderi flowers all summer.
This will ensure that your Mandevilla Sanderi continues to blossom beautifully. Mandevilla Sanderi requires sandy, well-draining soil that is rich in organic matter. A decent potting mix includes peat moss, sand, and leaf mold.
The plant prefers slightly acidic to neutral soil pH, although it may also survive slightly alkaline soil. Water your plant once a week until you detect damp soil or water draining from container plants.
Maintain a moist but not dripping wet soil that drains well; reduce watering throughout the winter when growth slows, allowing the soil to dry out more between watering. The following are the factors to consider when caring for Mandevilla Sanderi:
Mandevilla Sanderi requires full sun for optimal growth and good bloom. However, it will still perform fairly well in partial shade if it has adequate water and nutrients. Mandevilla Sanderi should be placed in a location that receives at least 6 hours of sunlight.
After planting, maintain a moderate amount of sunlight through the blooming season by using a bright window so that your Mandevilla Sanderi can continue producing flowers all summer.
Mandevilla Sanderi should be watered once a week until you detect damp soil or water draining from container plants. If you notice that your plant is drooping and the leaves turn yellow and fall off, your Mandevilla Sanderi does not have enough water.
On the flip side, if your Mandevilla Sanderi is wilted and wrinkled, it means that this plant is overwatered and has been sitting in water for too long.
Mandevilla Sanderi needs well-drained soil that is rich in organic matter. The soil should be slightly acidic to neutral, but it’s okay if the pH is slightly alkaline. Mandevilla Sanderi requires sandy, well-draining soil that is rich in organic matter. A decent potting mix includes peat moss, sand, and leaf mold. The plant prefers slightly acidic to neutral soil pH.
Mandevilla Sanderi can tolerate night temperatures of 60 to 65 °F and day temperatures above 70 °F. The frost tolerance of this plant is around 25 °F, but it can be hardy to 20 °F in warmer climates. Temperatures should be above 30 °F for the best growth. Mandevilla Sanderi will not survive a hard freeze, even if it still looks alive.
Mandevilla Sanderi prefers high humidity, so mist them often and place them in a humid room to ensure that the humidity is high. If you notice brown edges on your leaves, it’s probably because there is not enough humidity. Humidity should be maintained at 60-80% while the Mandevilla Sanderi flowers.
Mandevilla Sanderi should be pruned once a year in the late winter to early spring. Prune your Mandevilla Sanderi right after its blooming period when it finishes producing flowers. Remove all tillers (shoots with only one flower on them) and dead canes immediately before they have a chance to split and spread disease through the entire plant.
Mandevilla Sanderi prefers high phosphorus, water-soluble fertilizer once every two weeks. A phosphate deficiency will cause the plant to show signs of yellowing and then eventually flower poorly.
A phosphorus overdose will cause leaves to turn bronze and eventually die. Mandevilla Sanderi prefers high nitrogen, water-soluble fertilizer once every two weeks as well. This will ensure that the plant receives high levels of nutrients needed for blooming all summer long.
Mandevilla Sanderi can be propagated by seed and vegetative cuttings during the spring and summer. Cuttings will take root quickly in a growing medium. Take stem tip cuttings at least 6 inches long for the fastest and easiest method.
Use a rooting hormone and place the stem tip in the rooting medium under high humidity, preferably over vermiculite and perlite. Keep the humidity high by placing a plastic bag over it and placing it in a clear container with about 1 inch of water in it. Mist daily and transplant to the garden after one month of growth on the cutting.
Mandevilla Sanderi should be repotted every 1-2 years. Repot this plant in the late winter to early spring when the plant’s roots have anchored in the pot. Always use a potting mix with high organic matter, like peat moss and leaf mold.
While it is okay if the soil is slightly acidic to neutral pH, it usually performs best with a slightly alkaline pH. A good compost would be acidic.
Pests and diseases:
Mandevilla Sanderi does not have many pest problems, but it does attract aphids, spider mites, whiteflies, and thrips. Aphids can be thwarted by using a good insecticidal soap to clean out the affected areas.
Whiteflies can be prevented by using neem oil or bacillus thuringiensis (Bt) spray to treat aphids and other small pests with contact. Spider mites can be controlled by cleaning your garden with organic insecticidal soap and then spraying your plants with neem oil to prevent these tiny pests from hatching.
How Do You Prune Mandevilla Sanderi?
Mandevilla Sanderi does well when pruning is done in early spring. Most of the plant stems need to be removed to create a more compact shrub. To do so, cut the entire stem right above where the leaves begin to wrap around it. Remove all of this unwanted growth by cutting off all new shoots and re-sprouting canes at the base.
Ensure that you use a sharp and pruning saw to remove these unwanted shoots and new growths. When it comes to pruning leaves, only cut them if they are dead or browned out because these are not even used for photosynthesis and will waste too much water when calculating how much water your plant needs throughout the growing season.
When pruning the leaves from Mandevilla Sanderi, make sure to cover the saw with a plastic bag to ensure that the plant is not getting cut.
The easiest way to do this is by cutting off the leaf and then sliding the bag over the stem before cutting through it. Here are steps to follow when pruning Mandevilla Sanderi:
- Trim all unwanted shoots and stems, and remove the dead leaves by using a pruning saw.
- Put a plastic bag over the saw to prevent any accidental cuts.
- Make sure that you trim off at least one inch above where the leaves start growing down around the stem.
- Prune off all new stems a week after pruning to ensure sufficient water and nutrients are transferred throughout the plant for its growth cycle.
- Remove all of the dead leaves and shoots that may be present on the plant.
- Cut back the new shoots roughly a week after pruning them to promote growth and ensure that they have properly rooted in their new location.
