Hoya plants, also known as wax plants, are popular for their attractive, fragrant flowers and easy care. Propagating Hoya from cuttings is a common method to expand your collection. Properly storing and handling cuttings increases the chances of successful rooting and healthy growth.
Preparing Hoya Cuttings for Storage
Before storing Hoya cuttings, select healthy, disease-free stems. Use clean, sharp scissors or pruning shears to make a clean cut just below a node. Remove any leaves from the lower part of the cutting to prevent rot and improve airflow. Allow the cuttings to callus for a few hours to a day in a dry, shaded area. This step helps prevent rot during storage.
Optimal Storage Conditions
Proper storage conditions are essential for maintaining cutting viability before rooting. Keep cuttings in a cool, dry place away from direct sunlight. Ideal temperature ranges are between 50°F and 70°F (10°C to 21°C). Avoid exposing cuttings to excessive humidity or moisture, which can lead to rot. Using a plastic bag or container can help maintain humidity, but ensure some airflow to prevent mold growth.
Methods of Storage
Refrigeration
Refrigeration is a common method for short-term storage. Place cuttings in a plastic bag with a damp paper towel to maintain moisture. Seal the bag loosely to allow airflow. Keep the bag in the vegetable crisper or a cool section of the refrigerator. This method can preserve cuttings for up to two weeks.
Room Temperature Storage
If immediate rooting is planned within a week or two, store cuttings at room temperature. Keep them in a well-ventilated container or loosely covered with plastic wrap. Place the container in a shaded area, avoiding direct sunlight and temperature fluctuations.
Monitoring and Handling During Storage
Regularly check stored cuttings for signs of mold, rot, or dehydration. Remove any damaged or rotting cuttings immediately to prevent spread. Maintain appropriate humidity and temperature levels. If using plastic bags, open them periodically to allow fresh air exchange.
Transferring Cuttings for Rooting
When ready to root, gently remove the cuttings from storage. Rehydrate slightly if they appear dry, and proceed with planting in well-draining soil or water. Ensure the cuttings are healthy and callused before planting to maximize rooting success.
Conclusion
Storing Hoya cuttings properly can significantly improve your propagation success. Focus on selecting healthy cuttings, maintaining suitable storage conditions, and monitoring regularly. With patience and proper handling, you can enjoy a thriving collection of Hoya plants propagated from cuttings stored with care.
