Now, let’s discuss how to propagate the Hoya Pubicalyx Hawaiian Royal Purple plant!

How to propagate Hoya Pubicalyx Hawaiian Royal Purple plant?

You can easily propagate these plants in three methods, which I will now discuss in detail! Let’s check them out!

1. Propagation of Hoya Pubicalyx Royal Purple plant through seeds

You can propagate Hoya Pubicalyx Hawaiian royal purple plant by sowing their seeds. This is an easy process to propagate these plants. But you must have much patience to wait to see the plant’s growth. It takes a lot of time to grow. However, this is the cheapest method of propagating these plants, if you have a mother plant. Let me tell you the complete process.

Firstly, collect some seed pods from the mother plant, which is healthy and mature. Make sure that the pods are neither too dry nor too young to collect seeds from them.
Then twist the pods there will be some seeds inside the pods.
Prepare a pot with the best quality soil mix and place the seeds inside the soil about an inch deep. Leave a space of at least 2-3 inches between any two seeds to allow root growth.
Water the pot and maintain the wetness in the soil to boost root growth. Place the pot in a bright place.
The seeds start growing roots in 4-5 weeks, after 5 weeks you can transfer the seedlings into a pot with a suitable soil mix.

We will discuss the pot and the soil mix that is suitable for planting this plant in further paragraphs. So, keep reading!

2. Propagation of Hoya Pubicalyx Royal Purple plant through cuttings

Most plant lovers use this for propagating this plant as it is an easy and carefree method. Also, it is cost-free if you have a mother plant and may not take as much time as a seed takes to grow into a seedling. Let us know the method in detail.

Cut a stem from a strong and old plant. It is better if you cut one of the bottom stems of the plant, as it produces the root growth fastly. Make sure that the stem has at least 10 inches in height.
Remove all the bottom leaves of the stem, and leave some leaves at the top. You can dip the bottom end of the stem in the rooting hormone to boot the root growth. However, the stem can produce the roots even if you don’t use the hormone.
Now, you can use sphagnum, perlite, or soil as a medium for propagating things.
Place the stem into the soil (or in any other medium) up to an inch in depth. Maintain the soil dampness to encourage root growth.
It takes at least 2-3 weeks to produce the root system. You can change the pot after a successful propagation.

You can propagate these beautiful plants even in water. You need to put the stem in a container of water after applying liquid rooting hormone at the bottom end. It takes at least 15 days to see the root growth. Once you observe the root growth, transfer it to a pot with soil.

3. Propagation of Hoya Pubicalyx Royal Purple plant through layering

It is the fastest method of propagating plants. But, it needs much care and attention. Beginners should be attentive, for the first time. Let us know the method in detail.

Select a strong, mature, and bottom stem, which is in contact with the main stem, for propagating this plant by using the layering method.
Select a suitable pot and potting mix for propagating this plant. And prepare a pot before you start the process and place it beside the pot with the mother plant.
Make a small wound to the stem, by cutting it ½ in depth and 2 inches in height. You apply rooting hormone to the wound if you like to boost the root growth.
Bend the selected stem, such that the wound touches the soil mix in another pot, without any damage to both stem and mother plant. Secure it by placing a small rock on the stem. You can use floral pins to avoid the movement of the stem.
Let the soil be wet in the pot which we are using for propagation.
In just a week or two, you can observe the root growth in the wounded place.
Then gently cut the stem from the mother plant safely using a sharp knife to avoid mushing.

4. Air layering of Hoya Pubicalyx Royal Purple plant

It is also the same as the above process, but there is a slight difference, which we discuss now.

After making a wound to the selected stem, apply some rooting hormone (optional) and cover it with sphagnum or soil.
Then wrap a cover around it and secure it with floral ties.
This helps in maintaining the humidity and thus root growth.
In 1-2 weeks you can see the roots growing from the wound.
Separate the stem from the mother plant using a sharp knife and plant it in another pot.

Now, you know how to propagate this plant. But do you know how to care for a Hoya Pubicalyx Hawaiian Royal Purple plant at home? Let’s discuss this in detail!

How to care for Hoya Pubicalyx Hawaiian Royal Purple plant?

The plant also undergoes dehydration and may stop its growth in these situations.

The care guides of these plants suggest that these plants grow well when they get bright indirect sunlight for 4-5 hours daily. These plants can survive in a little more indirect sunlight for a while. But if the plant does not get enough sunlight, you can observe some problems like a fall in the growth rate of the plant, drooping foliage, not blooming, and other such diseases. So, it is better to place your plant outdoors under a shade or indoors near windows to provide enough light.

2. Watering Hoya Pubicalyx Hawaiian Royal Purple plant!

Hoya pubicalyx Hawaiian Royal Purple plants need adequate water to survive. Because water supplies nutrients to the plant and helps in energizing the plant. As this plant has a sensitive root system, watering it can be a tricky task. The amount of water you supply should satisfy the soil and the roots of the plant. Both overwatering and underwatering can damage the plant.

Watering causes root rot, and fungal infections and may sometimes lead to plant death. While underwatering this plant makes this root system dry and affects the performance of the root. Dehydration makes the plant weak and droopy. A good rule for watering the plant is always checking the soil’s wetness before you water. Water the plant, only if the first one-inch layer of the soil is dry. Water it slowly without disturbing the soil mix, until the excess water comes out of the drainage holes.

3. Suitable Temperature range and Humidity level for Hoya Pubicalyx Royal Hawaiian Purple plant!

Hoya Pubicalyx Royal Purple plants like warm conditions to thrive. They adapt to room temperature and humidity which is one of the best qualities of the plant. The suitable temperature range of the plant is between 60-80 degrees Fahrenheit. The rise or fall in the temperatures for a short period can be neglected, but if the plant is left to the extreme temperatures for a long period will show its effect on the plant’s health.

Temperatures below 55 degrees will stop the growth of the plant and may eventually kill it. So, bring the plant indoors during the winter, if you have placed it outdoors in shade. High temperatures will damage the sensitive foliage of the plant and can also lead to dehydration in the plant. So, maintain the plant in the above range of temperatures.

While talking about the humidity, the moisture present in the home best suits your plant. In humidity levels of 40-60 %, the plant thrives and produces nice fragrant flowers. Above or below the level will damage both the plant’s look and health.

4. Soil mix for planting Hoya Pubicalyx Hawaiian Royal Purple plant!

Soil plays a crucial role in maintaining this plant. Hoya plants need a well-draining soil mix to get planted and this subspecies is not an exception to it. Well-draining soil mix never holds the water and dries quickly, thus keeping the root system healthy.

You can prepare a well-draining potting mix by adding ¼ of perlite, ¼ of peat, and ¼ of orchid bark to the ¼ of normal household soil. Always use this mix to plant these kinds of plants. This not only dries quickly but supplies enough nutrients to the plant.

5. Potting Hoya Pubicalyx Hawaiian Royal Purple plant!

Hoya Pubicalyx Hawaiian Royal Purple plants need to be potted in well-drained pots as the roots of these plants are prone to root rot. The Hoya publicly Hawaiian Royal Purple species are not an exception to this. They love to be dry for a while between watering. The pots that are made up of plastic and other such materials will hold the water for a long time. This may cause the roots of the plant to get rotten.

Use the pots that are made up of soil. Because clay pots, unglazed ceramic pots, and unfinished terracotta pots help in transferring the air (oxygen) to the root system of the plant. The soil which is in contact with the walls of their porous walls dries quickly. Thus they are well-suited to use for potting these plants.

While you pot the plant, place gravel at the bottom of the pot because it avoids clogs of drainage holes and thus drains the excess water quickly. After the gravel layer fills the pot with a layer of well-draining soil then place the plant. Now fill the pot with the remaining soil at the sides and top of the root system of the plant.

6. Repotting Hoya Pubicalyx Hawaiian Royal Purple plant!

Your Hoya Pubicalyx Hawaiian Royal Purple plant might be willing to stay in the same pot and grow pot-bound roots, which encourages drops blooming, but having the pot-bound roots may cause root rot. Fertilization affects plant growth. So, it is better to repot your plant every 2 years to maintain it. Early spring to early summer is the best time to repot these plants, as this season helps encourage growth.

Use only a 1-2 inch larger pot than the older one. Because the large containers which hold more water may not be liked by your root system. Extreme weather conditions are well-known for reporting the plants.

To repot this plant, firstly dampened the soil to avoid root damage while pulling the plant out of the pot. Gently drag the plant out from the old pot. Separate the old soil which is stuck to the roots and follow the process of potting. You should repot that the roots of it are rotten to prune the rotten parts of the root system. Use sharp gardening equipment to prune the roots, if needed.
