From our perspective as Dendrobium canes, our need for support is a direct consequence of our evolutionary success. In our native habitats, we are epiphytes, meaning we grow upon other plants, primarily tree branches. Our tall, sometimes top-heavy canes (pseudobulbs) evolved to reach for dappled sunlight through the forest canopy. In this setting, our roots anchor us firmly to the bark, and the surrounding tree structure provides a natural framework that buffers us from strong winds and heavy rain. When cultivated in pots, this supportive environment is absent. The confined root system and the often still, humid air of a home or greenhouse do not mimic the natural bracing we are adapted to. Without intervention, the weight of our own growth, especially when laden with leaves, flowers, or keikis (offshoots), can cause us to lean excessively or even topple, risking damage to our root system and physical structure.
The choice of stake is crucial for a harmonious relationship. A thin, flimsy stake is an ineffective partner, while a thick, heavy one can damage our delicate root ball during insertion. A bamboo or wooden stake with a diameter roughly one-third to one-half the thickness of our base cane is ideal. The act of staking should be done with care, preferably when we are young and actively growing, or during repotting. Insert the stake vertically into the potting medium, close to our base but avoiding direct contact with our central rhizome and any healthy, white roots. A sudden, forceful insertion can sever our vital root connections, causing significant stress and setting back our growth. Think of it as introducing a new support tree into our immediate environment—it must be done with minimal disruption to our established foundation.
How you attach us to the stake is perhaps the most critical detail. We are living, growing organisms, and our canes need room to swell with stored water and nutrients and to perform subtle movements. Using rigid, non-breathable materials like wire or tight string can girdle and scar our tissue, creating wounds that are entry points for pathogens and physically inhibiting our growth. Soft, flexible plant ties, velcro straps, or even strips of old nylon stockings are far superior. They provide secure but gentle support. Tie us loosely enough to allow for slight movement and future thickening, but firmly enough to hold us upright. Create a figure-eight pattern with the tie, looping one side around the stake and the other around our cane, with the tie itself crossing in between to prevent chafing. Check these ties periodically as we grow and adjust them as necessary.
Proper staking is not merely about preventing a fall; it is about optimizing our potential. An upright posture allows our leaves to be positioned for maximum light absorption, fueling photosynthesis and strengthening the entire plant. It improves air circulation around our leaves and canes, reducing the risk of fungal and bacterial diseases that thrive in stagnant, damp conditions. Furthermore, by keeping our growth orderly, you allow each cane its space in the sun, preventing a tangled thicket where pests can hide. Most visually, for you, the caregiver, a well-staked Dendrobium showcases our elegant form and magnificent floral displays to their fullest advantage, allowing the beautiful pendulous flower spikes we produce to drape naturally without the entire plant tipping over.
