Hoya Kerrii

Watering is one of the most important aspects when taking care of Hoya Kerrii. You should water sparingly, and only after the top few inches of soil are dry. Feel the top of the soil and if it’s dry, water it thoroughly until water begins to run out of the pot’s drainage holes. After watering, allow the top layer of soil to dry before the next watering. As a rule of thumb, this species should be allowed to dry out between waterings.

Hoya Kerrii thrives when provided bright, indirect light. A few hours of direct sun each day can really help this species, but avoid intense, direct sun in the afternoon as this can scorch the leaves. If the plant is not in direct sun, make sure it is in a spot where it will receive as much light as possible. Regularly rotating the plant can also help ensure the leaves spread evenly.

Hoya Kerrii prefers temperatures between 65°F and 80°F (18°C to 27°C), with ideal nighttime temperatures around 65°F (18°C). Make sure to keep the temperature above 59°F (15°C) both during the day and at night, as lower temperatures can cause long-term damage to the plant. Similarly, try to avoid temperatures higher than 86°F (30°C).

Hoya Kerrii prefers a moderate to high level of humidity, between 40 to 70%. If the air is dry, you can increase the humidity by misting the plant with water or by placing a humidifier in the room. You can also group the plant with other plants to create a microclimate with higher humidity. Make sure there is proper air circulation around the plant, as stagnant air can create disease problems.

Hoya Kerrii prefers a soil that is slightly alkaline and that is well-draining and airy. To replicate this, use a potting mix that consists of one part peat, one part perlite, and one part vermiculite. To lower the pH of the soil, mix in horticultural charcoal or a small amount of bone meal.

Hoya Kerrii should be fed with a balanced, slow-release fertilizer once a month during the spring and summer months. Avoid fertilizing it in the winter unless you are sure the plant is actively growing. When fertilizing, mix the fertilizer according to package instructions and apply in small amounts. Over-fertilization can lead to burn and can be toxic to the plant.

Common pests that may attack Hoya Kerrii include mealybugs, scale, thrips, and aphids. To get rid of pests, you can wipe the leaves down with a cotton ball dipped in rubbing alcohol or mix a water and dishwashing solution. You may also mix some neem oil and water and spray the solution onto the plant. These solutions should be used on the plants sparingly and with caution, as they are not always safe for consumption and may be potentially dangerous to humans and pets.

Hoya Kerrii should be repotted every one to two years, or when the soil becomes depleted of nutrients. When repotting, choose a well-draining soil and a pot with drainage holes. Make sure the pot is large enough for the plant’s root system to fit comfortably, and use a potting mix that consists of a mix of one part peat, one part perlite, and one part vermiculite.

Pruning Hoya Kerrii can help maintain its shape and keep the plant healthy. It can help reduce the number of pests, improve air circulation, and encourage additional growth. To prune, use clean, sharp shearing scissors and start at the base of the plant. Be sure to only remove dead or diseased leaves and stems.

Mulching is not required for Hoya Kerrii, but it can help retain moisture in the soil and reduce weeds. Choose a mulch that is made of organic material, such as bark, straw, leaves, or grass clippings. Spread an even layer around the plant but steer clear of the stems and leaves.

Hoya Kerrii can be propagated by cuttings and through seed. To propagate from cuttings, cut a stem segment that has at least 1 leaf and several buds. Dip the cut end in a rooting hormone and place in moistened perlite or sand. To propagate from seed, use a medium that is free-draining and consists of perlite and peat. Provide the seed with indirect sunlight and regular irrigation for the best results.

Hoya Kerrii will need to be supported as it grows. You can use a trellis, a stake, or a string to guide the plant as it grows upward. Be sure to cut off any weak stems, as they can be a source of pest problems.

Hoya Kerrii does not need a rest period, however, it will benefit from being provided with slightly drier soil and cooler temperatures during the colder months. Allow the soil to dry out more between waterings and reduce the amount of fertilizer being given. Avoid exposing the plant to temperatures below 59°F (15°C).

Hoya Kerrii is not toxic to pets, so it is safe to keep around cats and dogs.
