Supporting vining houseplants is key to encouraging their natural growth patterns, leading to larger, more mature leaves and a healthier, more robust plant. By providing a stable structure, you help your plant mimic its natural habitat, directing energy into upward growth rather than sprawling outwards.
Why Do Vining Plants Need Support?
Many popular vining houseplants, such as the Swiss Cheese Plant (Monstera deliciosa), Pothos (Epipremnum aureum), and various Philodendrons (Philodendron hederaceum), are epiphytes or hemi-epiphytes in their native environments. This means they naturally climb trees, using aerial roots to anchor themselves to bark and absorb moisture and nutrients from the air. In a home setting, without vertical support, these plants tend to trail downwards, often resulting in smaller leaves and less vigorous growth.
Providing support offers several key benefits:
Encourages Larger Leaves: When a vining plant climbs, it perceives itself as reaching closer to the light source, which often triggers the production of larger, more mature leaves, sometimes even fenestrations (splits) in species like Monstera.
Promotes Stronger Growth: Upward growth helps stems become thicker and more sturdy, supporting the plant's overall health and stability.
Prevents Tangling and Damage: Supported plants are less likely to become a tangled mess, making them easier to care for and reducing the risk of accidental stem breakage.
Improves Aesthetics: A well-supported vining plant looks more intentional and impressive, adding a beautiful vertical element to your indoor jungle.
Which Type of Support is Best for Your Plant?
The best support depends on your plant's specific needs, growth habit, and your aesthetic preference. Each type offers unique advantages.
Moss Poles
Moss poles are ideal for plants that produce prominent aerial roots, such as Monsteras and many Philodendrons. These roots naturally attach to the moss, providing both physical support and, when kept moist, a source of humidity and nutrients for the climbing sections of the plant. Moss poles can be made of sphagnum moss wrapped around a central stake or constructed from coconut coir (coco coir).
Trellises
Trellises offer a broader surface area for climbing and are excellent for plants with less pronounced aerial roots or those you want to spread out more decoratively. They come in various shapes and materials, from classic wooden lattices to metal arches or plastic grids. Trellises are suitable for plants like Hoya, larger Pothos, or even some smaller climbing Ficus.
Stakes and Hoops
Simple stakes (bamboo, wood, or plastic) are effective for guiding young plants or providing temporary support. They are less ideal for plants that rely on aerial roots for attachment, as the plant will need to be regularly tied to the stake. Plant hoops or cages are another option, particularly for bushier vining plants, helping to keep their growth contained and upright.
How to Install and Train Your Vining Plant
Proper installation and gentle training are crucial for success. Planta recommends adding support when your plant is still relatively young to allow it to acclimate naturally.
Steps for Installing a Support:
Choose the Right Size: Select a support that is appropriate for your plant's current size and allows for future growth. A general rule is to pick a support at least as tall as your plant's current highest vine.
Position Carefully: Gently insert the support into the potting mix, close to the center of the plant's base. Be mindful of roots, trying not to damage them. If repotting, it's easiest to place the support in the pot before adding soil and the plant.
Secure Firmly: Ensure the support is stable and stands upright on its own. For taller supports, you might need to use a deeper pot or add a layer of pebbles at the bottom for extra weight and stability, though Planta generally advises against bottom pebbles for drainage.
Guide the Stems: Carefully arrange your plant's longest vines against the support. Orient the side of the stem with aerial roots (if applicable) towards the moss pole or trellis.
Attach Gently: Use soft plant ties, twine, or velcro strips to loosely attach the main stem and any climbing vines to the support. Avoid tying too tightly, as this can constrict growth or damage the stem. The goal is to provide guidance, not to choke the plant.
Encourage Aerial Root Attachment (for moss poles): If using a moss pole, gently press aerial roots against the moist moss. Over time, they will naturally grow into the pole.
Ongoing Care and Maintenance
Once your plant is happily climbing, a little ongoing attention will keep it thriving.
Keep Moss Poles Moist: Regularly mist moss poles, or gently water them from the top when watering your plant, allowing the water to soak into the moss. This provides humidity for aerial roots to grow into and encourages their attachment.
Adjust Ties: As your plant grows, you'll need to add new ties higher up the support and occasionally adjust existing ones to prevent them from becoming too tight or restrictive.
Prune for Shape and Health: Periodically prune back any unruly or yellowing vines to maintain your desired shape and encourage bushier growth. You can also propagate the cuttings!
Repotting Considerations: When it's time to repot, you may need a taller or wider support if your plant has outgrown its current one. Carefully lift the plant and its attached support, or gently remove the old support and replace it with a new one in the larger pot.
By understanding your vining plant's natural tendencies and providing the right support, you empower it to grow into a magnificent, mature specimen. Enjoy watching your green friends reach for the sky!
