Hoya Krimson Queen Care Tips

1.       Soil

Hoya Krimson Queen needs loose and breathable neutral to slightly acidic soil, although some species prefer somewhat alkaline soil. In general, the plant is not too demanding on the composition of the soil mixture

Peat soil is good, which needs to be compost of turf, leafy soil, and sand. It is recommended to add a bit of crushed sphagnum moss and a handful of charcoal to the finished substrate. For Hoya Krimson Queen, you can also use ready-made mixtures for orchids or violets.

2.       Lighting

Hoya Krimson Queen needs optimal light when growing. On the eastern or western windows, this plant blooms well for a long time and luxuriantly. The flower pot is kept further from the window on the south side, or shading agents are used to protecting the shoots from direct scorching rays.

Despite the size of the stems, it is not recommended to use Hoya Krimson Queen for landscaping a balcony or veranda in the summer. Under direct rays, the plant will develop worse. During the dormant period, try to keep the plant away from heating appliances in winter. 

3.       Watering

Abundant watering of Hoya Krimson Queen is required only during the growing season. It occurs during the spring and summer months. The earthen ball should always be in a slightly moistened state. 

In the winter months, it begins a dormant period, and water at this time should be drastically reduced. Spraying during this period is wholly excluded.

4.       Temperature

The optimal temperature for the growth and development of Hoya Krimson Queen is considered to be a range of 16-35 °C. But in addition to heat, the plant also needs air movement, so the room with Hoya Krimson Queen should be systematically ventilated. 

You should not expose the pot to cold air flows – the Hoya Krimson Queen does not like drafts. In winter, the temperature in the room can be slightly lowered – coolness up to 15 degrees is considered comfortable for the Hoya Krimson Queen, but if it is lower than that, it can make the plant die.

5.       Top dressing

Hoya Krimson Queen requires a sufficient amount of nutrients. The entire growing season, the plant is fed with liquid mineral compounds. Suitable as fertilizer for orchids and flowering succulents. Fertilizer is applied to the soil every couple of weeks, calculating the dosage according to the instructions. 

By adjusting the composition of nutritional supplements, you can achieve green mass growth or lusher flowering. Excessive amounts of fertilizer will adversely affect the health and beauty of the bush. 

If Hoya Krimson Queen has been transplanted into nutrient soil, it will begin to feed after 2-3 months. In winter, when the bush is resting, fertilizer is not applied.

6.       Humidity

Most types of Hoyas are not too demanding on the level of humidity, so ordinary room air usually suits the Hoya Krimson Queen. But its excessive dryness can still be harmful to the plant. Hoya Krimson Queen can be put on a pallet with wet pebbles or sprayed on its foliage during such periods.

You can also wipe or spray the vine’s foliage for sanitary purposes. It is periodically cleaned of dust, helping to improve the metabolic processes inside the leaf. But during the flowering period, spraying is not recommended.

7.       Transplant

Mature Hoya Krimson Queen needs to be transplanted every three years. Also, the young specimens need an annual transplant, as they will grow and develop much more intensively in large pots. 

Any pot will do, but there should be holes in the bottom to drain excess moisture. Good drainage from expanded clay or vermiculite is required.
