So, do you want to learn the best approach to growing a hoya krimson queen as your houseplant?

Well, below are all the growing tips that would get you started and keep you going;

Hoya Krimson Queen Soil Requirement

The basic soil requirement for planting the hoya krimson queen is a soil mixture that allows good aeration and good water drainage while retaining sufficient water to keep the plant happy.

Hoya’s are epiphytic plants that take no delight in excessive water. As a result, having compact soil and over-accommodating water to become soggy is terrible for the hoya krimson queen plant.

In severe cases, soggy and compact soil causes root rots which eventually lead to the death of the plant. Coarse sand is an excellent example of the type of soil you cannot use because of its capacity to hold water and become tightly packed together.

Your best choice is a soil mix that’s loosely packed and has good drainage and aeration features. You can make a DIY combination of the soil types that works using vermiculite, orchid bark, coconut husks, perlite, and peat moss.

There are several ways to combine either of these ingredients. Find out below;

  • Make use of 2 portions of peat moss and 1 portion of perlite or pumice
  • Make an equal mix of coconut husk, sand, pumice, clay balls, and vermiculite

Pumice and perlite help the soil stay loose for good drainage and aeration. Peat moss gives the soil capacity to retain sufficient water for the plant’s growth.

If you’d rather purchase a readymade solution for potting, we suggest the African violet mix with perlite and orchid bark.

Hoya Krimson Queen Light Requirements

Lighting plays a crucial role in the plant’s growth. Since hoya krimson queen is a variegated plant, it needs light more than regular green photosynthesizing plants.

The good thing about hoya’s lighting requirement is that you’ve got multi-lightening choices. Fluorescent light can also do just as much as the filtered sunlight for the plant.

Many people prefer artificial light because it’s more accessible indoors. It is even a wide belief that the plant thrives better under artificial light.

If you are using artificial lighting as an alternative source of lightning, only 5 hours of exposure is advised. However, if it is your only source of lightning, then you’d have to expose the plant to at least 14hours of artificial light daily.

Do not put the hoya plant under direct sun. It has to be filtered sunlight like placing the plant in a shade or at your east-facing window.

Too much sunlight or direct sunlight would scorch the plant’s leaf, causing complications in growth or eventually death.

How Often Should I Water My Hoya Krimson Queen?

Hoya plants have a mild water requirement. It can’t be overwatered or underwatered; your watering has to be calculated and just right. Just medium watering would do. Underwatering would make the plant wilt, stay malnourished and eventually turn the leaves into brown.

Generally, it’s advised to water the plants three times a week in summer and one- or two times during winter.

Temperature requirement

Hoya krimson queen can survive under room temperature that ranges from 30 to 40 °F. However, the rapid temperature change isn’t very favorable to the plant’s health.

The plant has low to no tolerance for frost and cold. As such, it is essential to make sure your hoya plant is kept warm during winter. By all means, avoid cold or draughty windows that expose the plant to cold and excessive water.

During the cold season of the year, always ensure the plants stay indoors and the room temperature stays just above 10°C during winter.

What’s the Hoya’s Humidity Requirement?

Hoya krimson queen strives exceptionally well under very high humid conditions, ranging from 69 to 80 percent. But no house has that kind of humidity for a plant.

A workaround for this growth requirement is quite essential, and all you’ve got to do is fill a tray with water, add some pebbles to it, and conversely place the plant on top. Growing the hoya krimson with other plants also increases the humidity around the hoya.
