Having trouble getting your Hoya plants to flower? You are not the only one feeling this. It’s a situation that many Hoya fans can relate to.
I know the secret why your hoyas aren’t blooming and, more importantly, how to get them to bloom again.

How long does a Hoya take to flower?
Hoya plants take 4-5 years to mature before flowering.Development of other parts of the plant, such as leaves, stems and roots, takes priority over flower production. Then, when they are old enough, they flower and produce fruit to start a new generation.
Hoyas have a hard time flowering because they have to be tall before they feel the need. Therefore, it is generally believed that a Hoya vine will not produce flowers until it reaches a length of at least 1 meter.
However, this is only a general rule, and a vine can grow up to 3 feet long without producing flowers for five years.
Flowering time for a hoya grown from seed with a 4-inch (10 cm) vine is three to four years. However, the time it takes to flower depends on the person, so it may take a while for this to happen.
Reasons why Hoyas do not bloom and solutions
1- Hoya flowers appear continuously on the same stem
Repeated pruning of a hoya can prevent it from flowering for long periods of time because the plant flowers from the same stem each time.
Therefore, you are not pruning the plant as it grows; wait for it to bloom
Although young Hoya vines look reddish purple, they eventually turn green.
Because the vine spreads quickly and uncontrollably, it is best to use a ring stake or other attraction method as soon as possible.
Between June and September, you can see hoyas in full bloom. However, the flowering stems should be left intact if you need to prune the vine because it has grown too large.
2- Low light levels negatively affect Hoya’s flowering ability
My Hoya caudata ‘Sumatra’ loves his new spot; He looks very happy there!Flowering hoyas require them to reach a certain size before they open, so if they don’t grow, they can’t flower. Thus, for the Hoya to flourish, it is essential to help the plant grow.
Because the leaves can burn if hoya plants are exposed to direct sunlight, they do best in a partially shaded indoor environment.
Remember, however, that hoya plants need light to grow, so if you keep them in a dark place all year round, they may never flower.
Hoyas like direct sunlight, but an indirect light source near a window will also work!When the sun is strongest (spring through fall), it’s best to keep the Hoya out of direct sunlight. However, during the winter months when leaf scorch is less likely, direct sunlight can promote flowering.
On the other hand, spotted hoyas can scorch the leaves if placed in full sun, so they need indirect lighting.
3- Hoyas thrive when transplanted frequently
In general, Hoya should be repotted every two to three years. Root clogging and stunted growth are the result of not replanting often enough.
If you don’t transplant your Hoya, it will have stunted growth and few or no flowers.
Hoya plants that grow well usually flower after three to four years. If a hoya hasn’t flowered in more than five years, it probably hasn’t been transplanted. Replant them in a larger container if this is the case.
Ideally, transplant your Hoya in early spring, between April and June. During the growing season (spring to fall), a fertilizer with a slightly higher amount of phosphoric acid is recommended to produce flowers and fruit.
4- Diseases
If your Hoya is affected by any of the following diseases, it will have difficulty flowering.
Putrefaction
The shoots become soft and wrinkled, change color and rot due to this fungal disease.
Cut off diseased shoots and treat wounds with activated charcoal if the fungus has not spread to other parts of the plant. Remove some of the soil from the container and replace it with charcoal.
The plant cannot be saved once the fungus has spread through it. To prevent fungus growth, water it in time and don’t let the soil get too wet.
Chlorosis
In chlorosis, photosynthesis slows down or stops altogether. The leaves lighten, turn pale yellow and develop white spots.
The plant weakens and looks sick. Chlorosis is caused by essential nutrients such as iron.
You need to spray it with a solution of chelated iron. It is more effective to spray the leaves than to water the root zone. Leaves can directly absorb descent iron and recover from chlorosis.
Alternarian spot
The fungus first affects the lower leaves of the plant, then moves upwards. It appears during frequent changes in temperature and humidity.
It is important to remove diseased leaves and treat the plant with copper-containing fungicides.
sooty mold
It prevents the plant from absorbing oxygen by clogging the pores. As a result, a dry film appears on the leaves as the fungus spreads.
To treat the fungal film, remove it, wash the leaves with soapy water and apply fungicides.
Brown spot (phyllosticosis)
Dark spots appear on the leaves, they spread and dry out the leaf, making it thin and brittle. Apply a fungicide solution to the root system before returning the soil to the pot.
Then, bulldoze off any diseased leaves and spray the entire plant with a fungicide solution.
5- Too big boat for Hoya
Potties work well for Hoya. The plant’s root system should spread out and fill the entire area.
Therefore, it’s best to transplant mature plants only infrequently, so that their roots have enough time to establish themselves in their new home.
The pot of an adult plant should have a diameter of 15-20 cm. The best place for a hoya is in a small pot.
Practical tips for getting your Hoya to flower
I’ve spoken to experienced flower growers who have told me things that will help those just starting out.
For example, if you want your Hoya to thrive, you can do three things: give it a water bath, let the soil dry, or apply a stimulating top dressing.

Use a water bath to allow the plant to flower. First, place the pot in a larger container of water heated to 86°F 30°C, making sure the entire root system is submerged.
Let stand for about 30 minutes, then place the plant sprouts in the container for 1 hour.
dry ground
In winter, place the pot in a dry, warm place to prevent the soil from becoming soggy. Also, make sure the plant is healthy and the leaves are not turning black.
To speed up the drying process, move the pot to an east-facing window once the soil is semi-dry. In spring, the plant blooms profusely with numerous buds.
stimulating fertilizers
Some flower growers use stimulating fertilizers to help the hoya flower. These stimulants increase the plant’s immunity and resistance to infection.
As a result, plants begin to grow more actively and bloom earlier and more abundantly after fertilizing.
Use a liquid fertilizer high in nitrogen to promote leaf growth and one high in phosphorus to promote flowering.

Key Points of Hoya Blooming Tips
- Only water the soil after it has dried out. Significantly reduce watering during the autumn-winter period.
- In the summer, give the plant more water and spray. The Hoya will bloom profusely in the spring if you dry out the soil in the winter.
- Hoya grows well in dry air, but needs regular watering to thrive.
- The ideal range for plant temperatures is between 64-77 degrees F (18-25 degrees C) in summer and 59 degrees (15 degrees C) and slightly higher in winter.
- In winter, place your Hoya in the south to have enough light. A daylight lamp needs at least 10 hours of light in winter.
