Hoya Carnosa Krimson Queen is a hearty wax foliage plant. We chose it for its resilience and vigor. This hoya is impressive as a container plant in combos or as a stand-alone hanging basket plant. The Krimson Queen's long vines will eventually put out a cluster of white flowers, but its real beauty is in its waxy green-and-white, almond-shaped leaves. Hoya Carnosa make good indoor houseplants, but they need to be exposed to indirect sun to perform well.
Hoya like to be kept on the dry side. Wait until the soil is good and dry before watering, but when you water, make sure you do so thoroughly. Water should drain from the bottom of the pot at each watering. Hoya do not go dormant in the winter, but their growth slows significantly. Do not fertilize in the winter
, but when the plant is growing (spring, summer and fall) use a balanced fertilizer
. Hoyas like high humidity. Anything north of 40% will keep them growing at their peak. Maintain a pH level of 5.0-6.0
Hoya will bloom naturally in the spring as the days lengthen, but the clusters of white flowers are small and not the real draw to these plants.
We recommend that you pinch Hoya 5-10 days after transplanting
to your final container. An additional trim may be necessary later to shape your plants.
Space pots as needed for proper airflow and light penetration between foliage
. This will vary based on pot size size, but normal 2' centered spacing is usually adequate.
HeightControlPlant growth regulators are not necessary
for Hoya Carnosa Krimson Queen. Allow the plant to grow, and shape the pots through proper pinching.
are Hoya's primary pests, but keep an eye out for spider mites and thrips
Hoya Carnosa Krimson Queen is not prone to many diseases, but don't oversaturate the soil
. If the plant sits in moist soil for an extended amount of time, you could end up with root rot or botrytis
. Botrytis grey rot is usually associated with wet or humid conditions. You can prevent botrytis by allowing the plant to dry out between waterings, allowing for good airflow in your greenhouse, and spacing to allow the sun to penetrate to the soil level. The most common chemicals used to treat botrytis and root rot are Medallion and Banrot. Use them as a drench according to each label's instructions.
Planting Hoya Carnosa Krimson Queen Liners
- We recommend planting 4-5 starter plants per 10 inch basket. Use a well-drained soil in your baskets and plant your starter plants deep, allowing the ellepot to be completely covered by the soil. If you are planting 4" pots, 1 plant per pot should be sufficient. Plant it directly in the middle of your pot.
- Pinching is recommended 5-10 days after transplantation. A second pinch may be necessary depending on the size and shape of the final pot.
Cuttings vary in size between different plant families. These rooted starter plants will arrive ready to be transplanted in to your final container. If they are to be used in a landscape application, you will need to establish them in a 4 inch pot or an 1801 before planting outside.
