These plants are the easiest ones to grow, but still, you need to consider various points in mind for their ideal growth and development.
1. Fertilizer Considerations:
It is a low-maintenance plant and does not require much fertilizer to promote its growth. But you can fertilize the hoya retusa plant in the late spring, as it will help promote the prolific growth rate. The best one will be the organic fertilizer. Using coffee grounds and tea as a fertilizer will also help to feed the plant.
Do not fertilize your plant in winters, as it does not need many nutritional requirements.
2. Humidity Considerations:
Hoya retusa is native to tropical areas due to which it loves humidity. Besides, the plant can also grow well in the domestic humidity level. About 40% of the moisture will be enough for its growth.
But if you notice stunt growth or change in the leaf’s color, you must use a humidifier or a pebble tray. Using these strategies will help in maintaining the humidity level.
Moreover, another thing that can help maintain the humidity is to put your plants in bunches. In this situation, you must consider regular air circulations within the plant.
3. Growth Zone:
The ideal growth zone of the hoya retusa plant is the USDA zone from 10 to 11.
4. Pot Requirements:
Hoya retusa loves to grow in terracotta pot, as it has ample drainage holes at the base. This pot will help in promoting its growth rate. The plant likes to dry the soil quickly and cannot survive well in the soggy ground.
5. Pruning Considerations:
Hoya retusa care also needs pruning, and you need to remove the unhealthy leaves from it the time. It will keep your plant healthy with an admiring appearance.
A well-draining soil mix is the perfect one to let this plant bloom well. You can include peat moss, coco coir, or some perlite in your soil to prepare a fantastic growing mixture.
If you feel your soil is dense, then adding perlite or coarse will help maintain drainage and aeration. Make sure to add an equal ratio of these mixtures in the ground for Hoya.
7. Hoya light Requirements:
The ideal condition of this plant’s growth is bright sunlight. However, you can also grow the plant in medium and artificial light. Hoya retusa does not love to grow in low light, and it also impacts the growth and appearance of this plant.
Lack of sunlight maintenance will result in the lumpy, discolored, and unhealthy growth of the plant. So, keep our eye on the light availability both indoors and outdoors.
8. Temperature Considerations:
Hoya retusa is a low-temperature-loving plant, and they do not like more significant fluctuations in temperature. But in the blooming season, the optimum temperature required by these plants is around 50 degrees Fahrenheit.
While in daily routine, the average temperature to let this plant grow is between 50 to 80 degrees Fahrenheit. Negligence in managing the temperature will not help prolific growth, and hoya retusa cannot survive well. Too cold temperatures can also cause yellowing of the leaves and can also result in stunt growth.
9. Water considerations:
The water considerations of this plant differ with different seasons. It requires a medium amount of water, and in summers, you need to water the plant twice or thrice a week. Check the upper three inches of soil, and if it gets dried, your plant needs water. While in winters, watering the plant twice a week will be enough.
The substrate is another factor on which water requirement depends. If your soil is lightweight, then frequent watering will work, while if it’s heavy, you need to be waterless. But make sure that you do not overwater your plant. Over-watering can cause increased chances of fungal attacks and root rot. Hoya retusa hates to grow in soggy soil.
Also, try to use room temperature water with the absence of heavy metals.
