Why Is My Mandevilla Not Blooming?
Your Mandevilla plant is not blooming because it is most likely lacking the proper care conditions to grow optimally. As a tropical and subtropical plant, the Mandevilla vine has certain requirements that need to be met.
Also, another reason could be that it’s not the right season for it to bloom. The Mandevilla flowering season can differ according to where the plant is grown. For instance, the Mandevilla plant can flower any time of the year when it is grown in a tropical or subtropical setting.
Yet, when planted in more temperate climates, the Mandevilla blooming season usually starts in the spring or early summer.
How To Make Mandevilla Bloom?
There are several factors that can help get Mandevilla to bloom. We will be discussing each one to help you understand how they can affect the flowering of the Mandevilla plant.
You will also learn to understand how one factor can influence the other factors. From this, you can start to figure out where you may need to improve.
– Make Sure the Plant Receives Ample Sunlight
The Mandevilla plant is a tropical and subtropical bloomer, and while the plant can tolerate some shade or even partial shade, the flowers often come out when the plant experiences optimal sun exposure. The more sun the Mandevilla plant receives, the more flowers will come out from the vines.
As we mentioned in the previous section, when your Mandevilla plant is thriving yet not flowering, this phenomenon may be due to a lack of sunlight exposure. So, you can place the Mandevilla plant in a spot where the vine can receive at least six to eight hours of direct sunlight. Do this gradually so as not to shock the plant from sudden sunlight exposure.
Ideal locations are south-facing spots or east-facing areas. Also, the gentle sun exposure provides adequate light without possible leaf burns to the Mandevilla plant.
On the other hand, some gardeners have noticed that the Mandevilla plant even enjoys the harsh noon and afternoon sun, while some species can also flower in areas with bright indirect sunlight. In any case, allow the Mandevilla plant to bask in the light, and pretty soon, you will begin to see the buds forming into blooms.
– Check if the Mandevilla Is Hydrated
To make sure that your Mandevilla is hydrated, you can check the soil at the base of it. The soil should be moist to the touch and not overly wet. When the soil is constantly wet, the condition may cause root rot, and if the soil is too dry, the Mandevilla plant will begin to wilt from dehydration.
When planted in temperate regions, reduce the watering during cooler periods of the year. Water only when the topsoil is dry an inch from the top.
Keep in mind that the tropical and subtropical nature of the Mandevilla plant means that it can get dehydrated easily due to the hot weather. Placed in hot and sunny areas of the home or garden, the Mandevilla plant will require more watering to keep it from drying out. Also, the bigger the plant gets, the more frequent it needs to get water, so keep that in mind too.
– Ensure the Plant Is Adequately Fertilized
Aside from watering, the Mandevilla plant can also require fertilizing every two to three weeks during the plant’s growing season. Using a water-soluble high-phosphorus content fertilizer can help the plant bloom. Fertilizer mixing ratios vary according to manufacturers, so you will need to read the directions for specific application methods and frequencies.
You can discontinue fertilizer application during the cool winter days and resumed during the spring and summer seasons. Doing so will avoid unwanted reactions from the Mandevilla plant.
– Make Sure the Mandevilla Has the Correct Soil
To ensure a hospitable soil condition, you should make sure your Mandevilla plant has well-draining soil, preferably a mix of potting soil, some peat moss, and some builder’s sand. Provide the root system of the plant with some growing area. When placed in a container, repot the Mandevilla plant once the roots come out of the drainage holes.
So, poor drainage can be another cause why your Mandevilla plant is not blooming. When the soil around the plant retains too much moisture, this can cause the plant to go into survival mode. When this happens, the Mandevilla plant will focus all of its energy on repairing and healing itself and will not focus on producing flowers.
– Keep the Correct Room Temperature for the Plant
The Mandevilla plant prefers warm temperatures over colder ones. When the temperatures drop below 65 F, the Mandevilla plant may stop producing flowers and go into forced temporary hibernation. When exposed to cold temperatures for prolonged periods, the Mandevilla plant may experience a sudden demise and die off.
When the Mandevilla plant is placed in a container, you may bring the plant indoors if you live in a region where cold seasons exist. You should also ensure that your indoor temperature is around 65 F or higher. Otherwise, if left outdoors in the cold, the Mandevilla plant will eventually perish.
– Prune Your Mandevilla Plant Timely
Pruning can encourage the Mandevilla plant to bloom. Best done during repotting or during the early part of spring, pruning triggers the vine to produce flowers. However, we should note that the more important factors, such as light, temperature, and water, are already present at the ideal levels.
– What Is the Magnificent Mandevilla Plant?
The Mandevilla plant is a tropical and subtropical genus of flowering vines. Moreover, the plant was first described in 1840 and named after British diplomat and avid gardener, Henry Mandeville. The Mandevilla plant is sometimes commonly called the Rocktrumpet plant, owing to its flowers that are in the shape of trumpets.
– Where Is the Mandevilla Plant Native To?
The Mandevilla plant is native to Central America, South America, Southwestern United States, Mexico, and the West Indies. Many varieties of the Mandevilla plant originally came from the rich forests of Rio de Janeiro, Brazil.
– Does the Mandevilla Plant Produce Flowers?
Yes, it does! As a warmth-loving vine, the Mandevilla plant often produces fragrant flowers, although some varieties do not produce any scent at all. The Mandevilla flower also comes in an array of spectacular colors, with many hybrids formed over the passage of time.
– What Makes the Mandevilla Plant Popular?
The trailing characteristics of the Mandevilla plant make the vine a popular plant in many gardens. Placed on trellises, pergolas, or against walls and balconies, the Mandevilla plant provides lush foliage and tropical beauty to many homes and gardens.
– Is Mandevilla a Hardy Plant?
That depends on the species. While the Mandevilla plant can be considered a tropical plant, some species can be hardy in USDA zones 9 to 11.
To enjoy the flowers of the Mandevilla plant, let’s go over what we’ve gone through so far:
- The Mandevilla plant can be coaxed into flowering when exposed to more sunlight, approximately six to eight hours each day. Also, as a warmth-loving plant, the Mandevilla needs temperatures above 65 F to grow and produce flowers
- The lack of water can cause the Mandevilla plant to stop flowering, so ensure that the soil around the base of the plant is consistently moist, and not excessively dry or wet
- The Mandevilla plant can benefit from fertilizers that are high in phosphorus to encourage the plant to bloom
- The soil of the Mandevilla plant should have sufficient drainage yet hold enough moisture to keep the plant hydrated. Equal parts of potting soil, peat moss, and builder’s sand are ideal
- Pruning can encourage the Mandevilla plant to develop blooms in tandem with the right levels of sunlight exposure, temperature, and watering.
Now that you’ve learned the important factors in getting the Mandevilla to bloom, you’ll know what you need to encourage your plant to flower. With the right patience and care, your Mandevilla plant will reward you with more foliage and breathtaking blooms in no time!
