The Plant Care Guide for Mandevilla plants
The Mandevilla plant requires a bit of care while growing and in turn reward you with colorful large blooms for several months!
Let us look into the care requirements of the Mandevilla hybrids.
How to water the Mandevilla plants?
The Mandevilla plant must be protected from root rot. To do this it needs to be watered when the top two inches dry out. Take your finger and place it inside the soil up to the second knuckle.
When the soil feels dry, it’s time to give it a thorough drench.
Never let the soil get soggy as that invites root rot.
In the dormant winters, water sparingly once a month, enough to keep it alive.
How much Light does the Mandevilla plant need?
The Mandevilla plants like bright rooms with good sunlight. Place it near a sunny window and it will thrive.
Remember, the more sunlight it gets, the more blooming power!
The only catch here is to protect them from direct exposure to harsh intense afternoon sun. The plant can get burned under direct sunlight.
You can achieve this by using sheer curtains or placing the pot at some distance from the windows. When decorating on the porch or balcony, place the plant in areas of partial shade.
A place indoors receiving morning and evening sunlight is ideal.
Some people prefer to take the indoor Mandevilla plant outdoors for the summer.
You need to protect the Mandevilla from strong winds.
Soil requirements of the Mandevilla vines
Place your Mandevilla hybrids in well-drained soil. A succulent or cactus mix with peat moss or a commercial potting mix with peat moss and some sand/ perlite would be great.
The pH of the soil needs to be 6.6-7.8.
Place the Mandevilla plant in a pot with good drainage holes. The size of the pot should be large to allow the roots to spread but not that large to produce more roots and fewer flowers on the stems.
Re-pot every two or three years.
Temperature requirements of the Mandevilla plants
The ideal temperature range for the Mandevilla plant is 18-29C (65-85F).
Mandevilla cannot survive chilly temperatures and frost. The minimum temperature it can bear is 13C or 55F.
Give it a warm temperature year-round.
Does the Mandevilla plant require Humidity?
The Mandevilla plant thrives in high humidity. They need a relative humidity of about 50%. Group the plants or use pebbles filled water tray, or use an electric humidifier to maintain humidity near the plant.
You can also place the plant in rooms with high humidity like a bright bathroom or kitchen.
Fertilizer requirement of the Mandevilla plant
If you have recently bought your Mandevilla vine, you don’t need to fertilize for around two to three months. This is because the new soil will already have a slow-release fertilizer added to it.
Afterward, fertilize your plant during the growing season twice a month.
Use a liquid high phosphorus fertilizer to encourage healthy flowers. You can also use a balanced fertilizer or compost.
The last feed should be in late August with a balanced liquid fertilizer. Do not fertilize in winters.
Pruning helps to keep the Mandevilla plant’s size in control.
Prune away generously going even up to trimming half its size in late fall. The size reduction will help conserve energy and help to prepare the plant for dormant winters.
The spent flowers can be pinched off to encourage more blooms. Trimming away the branches does the same as flowers form at the tips of new branches. Pinch off about half an inch or ¼ the end of each stem.
Remove the dead and decayed plant parts as and when you see them. Trimming and pinching is essentially a must if you want a healthy, dense, and bushier plant.
Problems Encountered While Growing the Mandevilla plant
Yellow leaves or abundant leaf fall is mostly due to overwatering or exposing the plant to chilly temperatures.
Cut back on the watering schedule and place your plant in a warm area.
Lack of adequate sunlight causes tall and spindly growth and fewer blooms. Place the plant in a bright area receiving at least 5-6 hours of sunlight per day.
Lack of moisture or humidity can dry up the plant. Place it in areas of high humidity or use an electric humidifier or water-filled pebbles tray.
Brown spotted leaves usually occur in fungal infection or pest infestation. Inspect closely to differentiate the cause and treat accordingly.
Mandevilla vines are sturdy and do not encounter any problems or diseases. However, under less than ideal conditions, they can become weak and susceptible to spider mites, whiteflies, and mealybugs.
Get rid of the bugs using a strong pressure water hose. You can also use neem oil or insecticidal soap spray to get rid of them.
Cut off the diseased parts if you happen to spot fungal growth.
Due to slight toxicity, it is better to keep pets and children away from reaching out to the Mandevilla plant.
The Mandevilla plants are sturdy evergreen vines that are commonly grown in many states of the US.
They need to be protected from cold temperatures and windy dry areas. Being tropicals, place them in warm areas having bright filtered or indirect sunlight.
Give them 50% humidity and water them once the top layer of the soil dries up. Fertilize every two weeks with a liquid fertilizer having high phosphorus content for flower growth.
Sit back relax and enjoy the blooms from spring to fall every year!
