Flowering plant

Hoya Krimson Queen flowers are one of the sole reasons why people collect this unique plant. It produces umbels of small, star-shaped, waxy-looking flowers that are often quite fragrant. An umbel is a rounded raceme of flowers. Depending on the species and variety, the flowers can be pink, white, purple, brown, or even red. 

Most young plants may not flower for up to three years. However, adequate light is essential to achieve flowering after maturity. Once the flower buds sprout, they can bloom at any time of the year.

Care Tips

Light Requirement

The Hoya Krimson Queen thrives when given plenty of bright light, either indirect or filtered. Some do well with about two hours of direct sun exposure in the morning or evening, but too much sun exposure can burn their leaves or turn them yellow. Therefore, the ideal location for your Hoya Krimson Queen is an east-facing window with plenty of bright, indirect light.

Temperature Requirement

The tropical plant Hoya Carnosa Krimson Queen is well known. This plant prefers the same temperatures that we do, that is, ambient temperatures on average. It can only survive and tolerate temperatures between 61 and 95 degrees Fahrenheit (16-35 degrees Celsius). 

These recommended temperatures are sufficient for the Hoya carnosa variegata to survive and thrive in its habitat.

Water Requirement     

The Krimson Queen of Hoya carnosa does not like being watered too much. You should water the plant when the soil dries out completely. Because these plants are succulents, they tolerate drought, so it’s best to water them less frequently.

Water your Hoya Krimson Queen frequently, about 1-3 times a week, depends on how hot and dry your area is during spring and summer seasons. Growth naturally slows down in the fall and winter, and they don’t use as much water. So water sparingly in fall and winter, giving just enough, so the soil doesn’t dry out completely.

Humidity Requirement

Maintaining high humidity is an essential part of Hoya Carnosa Krimson Queen Care. This delightful plant loves high humidity. Because this variegated Hoya is a tropical plant with succulent foliage, it will enjoy higher humidity. 

Around 70 to 80% is optimal for the best Hoya results and increased flowering. However, it also thrives well in moderate humidity levels indoors.

Soil Requirement

The Hoya Krimson Queen soil requirement is a well-draining soil type that is very loose and has excellent potting soil. Hoya Carnosa Krimson Queen dislikes “wet feet” because it is susceptible to root rotting.

If you mix your own soil, use a combination of organic materials such as peat moss, perlite, gravel, vermiculite, hummus, charcoal, orchid bark, coconut husk, and clay balls.

Fertilizer Requirement

When choosing a fertilizer, use an organic one if possible. Liquid synthetic fertilizer has a higher chance of causing fertilizer burn at the root level. Feed your Hoya Krimson Queen every two weeks during the summer and spring growing seasons. In winter, there is no need to fertilize.

 The growth of Hoya ‘Krimson Queen’ can benefit from a light fertilizer once a month. However, the Hoya Krimson Queen does not need a lot of fertilizer. In fact, like other hoyas, if you give it rich soil or use compost, you may not even need to feed the plant. 

You can also choose something with more phosphorus and less nitrogen and potassium. Phosphorus (P) helps bloom and bloom. Nitrogen (N), on the other hand, is mainly used to promote vegetative (leaf) growth. And succulents don’t need a lot of potassium (K). 

Space Requirement

This tropical houseplant loves the sun as well as needs lots of sun to grow well. It demands bright filtered light or indirect light. This plant also likes well-drained soil with an existing great pot mix, so it grows well inside. The ideal place for Hoya Krimson Queen to be is near an east-facing window.

Growing and Planting Tips

Growing plant

Propagation

The easiest way to propagate Hoya ‘Krimson Queen’ is through cuttings. The steps are more or less the same as any other Hoya Carnosa. First, choose a young cutting with up to three leaves and no flowers. You can grow your cuttings in soil or water or use a propagation medium like perlite or peat moss. 

The best time for propagation is in spring or summer. You can also propagate in fall or in winter, but it will most likely take a little longer before you have a new plant.

Pruning

Pruning removes dead and dying branches, making room for new growth and protecting your plant from damage. Hoya Krimson Queen is a fast grower, but to shape and control its vigorous growth, prune Hoya Krimson Queen. Also, remove dead leaves and unhealthy-looking areas to keep the Hoya Krimson Queen more robust.

Better cut off some dead branches, bad branches, too dense branches, and young branches from the Hoya Krimson Queen. This can also improve Hoya Krimson Queen ventilation and prevent diseases and pests. Avoid excessive pruning so as not to hinder the flowering process.

Potting and Repotting

The Hoya Krimson Queen loves to be re-potted frequently. Depending on how much it has grown, you can re-pot it every year or two. The spring and summer months are ideal for re-potting Hoya. However, remember that when re-potting in winter or autumn, the plant may have the energy to fill the new pot with roots quickly.

 Hoya Krimson Queen requires soil with good drainage that is very loose and has excellent potting soil. Do not water immediately after re-potting; let the plants settle into their new mix for 2-3 days before watering. A pot, such as a hanging pot, is recommended for the plant. However, you should choose a pot that will prevent the roots from becoming tangled.

Problems and Troubleshooting 

Overwatering 

If you notice wilted leaves on a Hoya, it can be a sign of being underwater or overwater. It is very easy to overwater a hoya plant because these kinds of plants are drought tolerant and should not be overwatered. A common problem with Hoya Krimson Queen is stem and root rot.

Some useful tips:

  • Use a pot with at least one drainage hole.
  • Use potting soil that drains well.
  • Water only when the soil feels dry.

Underwatering

Hoyas prefer to stay mostly dry. However, they can also dry out if they are not watered enough. Therefore, another possible reason for your Hoya’s slow growth is a lack of water. Wrinkled leaves are sure that your plant is not getting enough water to maintain a normal growth rate.

Hoya ‘Krimson Queen’ should be watered whenever the topsoil is completely dry. Depending on your environment, this can be one to three times a week. However, Hoyas are more sensitive to over-watering, so it is preferable to under-water rather than over-water.

Nutrient Deficiency 

The nutrient deficit is also indicated by stunted development and leaf deformation. Nitrogen shortage is the most prevalent of these.

Some useful suggestions:

  • Indoor temperatures are good in general but avoid cold drafts and excessive heat.
  • Keep your Hoya Krimson Queen in filtered or indirect light.
  • Use phosphorus-rich fertilizer instead of nitrogen- and potassium-rich fertilizer. Nitrogen (N), on the other hand, is mainly used to promote vegetative (leaf) growth.
  • The best defense is to take great care of your indoor plant.

Flowering Problems 

It took three years for the Hoya Krimson Queen to bloom. This is because the spurs do not create flower buds once they emerge, but they can carry flowers throughout the season once they are present. As a result, it’s essential to keep an eye on the spurs, which carry the flowers each season.

 If buds break off before blooming, it’s possible that the potting medium was either too dry or too moist for too long.

Pests

 Hoyas attract pests. The most frequent pests that affect your Hoya Krimson Queen are mealybugs, spider mites, and scale. Furthermore, when a plant is stressed, it is more vulnerable to fungi, bacteria, and insects.
