ByRimon Chowdhury Updated on

Ever look at your garden and feel like you’ve run out of room? Or maybe you’re just dreaming of a way to add a touch of wild, natural magic to your landscape, something that feels like it’s straight out of a lush rainforest.

I know that feeling well. For years, I saw my trees as just providers of shade. But what if I told you they could be so much more? They can be living canvases, vertical gardens that draw the eye upward and create layers of unexpected beauty.

I promise, this isn’t some complicated technique reserved for botanical gardens. You can absolutely do this! This guide is your friendly companion, here to walk you through the wonderful world of growing plants on trees. We’ll explore the best plants for the job, exactly how to mount them without harming your tree, and the simple care routines that will ensure your new vertical garden thrives.

Let’s turn that empty trunk space into a breathtaking feature.

Why You Should Start Growing Plants on Trees (The Surprising Benefits)

Before we dig into the “how-to,” let’s talk about the “why.” This isn’t just a novelty; embracing this method comes with some fantastic perks. The benefits of growing plants on trees go far beyond just looking pretty—it’s a smarter, more dynamic way to garden.

This approach is a cornerstone of eco-friendly growing plants on trees, as it mimics how these plants exist in their natural habitats. You’re essentially creating a miniature ecosystem right in your backyard.

Here are just a few reasons to get excited:

  • Maximize Your Garden Space: You’re no longer limited to the ground! By going vertical, you unlock a whole new dimension for planting, which is perfect for smaller yards.
  • Create a Stunning Natural Aesthetic: Plants growing on bark create a breathtaking, aged, and serene look. It makes your garden feel more established and connected to nature.
  • It’s Healthier for the Plants: For a special class of plants called epiphytes, this is how they want to live! They thrive with the superior air circulation around their roots, which prevents rot.
  • Showcase Unique Specimens: It’s the perfect way to display the unique beauty of orchids, bromeliads, and ferns that might get lost in a crowded garden bed.
  • Sustainable and Low-Impact: You’re using an existing structure (your tree) as the foundation, reducing the need for new pots, planters, or soil.

Understanding the “Right” Kind of Plants: Meet the Epiphytes

Now, you can’t just take any old houseplant and tie it to a tree. The secret to success lies in choosing the right type of plant: epiphytes.

Don’t let the fancy name intimidate you! An epiphyte is simply a plant that grows on another plant for physical support but doesn’t harm its host. They aren’t parasites. They get their moisture and nutrients from the air, rain, and the organic debris that collects around them.

Think of them as polite houseguests. They just need a sturdy place to hang on, not to steal resources. This is the most critical part of our growing plants on trees guide—choosing the right guest for your tree.

Top Plant Choices for Beginners

Ready to pick out your first plant? Here are a few reliable, beautiful, and forgiving epiphytes that are perfect for getting started. Don’t worry—these are perfect for beginners!

  • Staghorn Ferns (Platycerium): These are the showstoppers! With their dramatic, antler-like fronds, they make an immediate architectural statement. They love dappled light and consistent moisture.
  • Bromeliads (Guzmania, Tillandsia): Many bromeliads, including the popular “air plants” (Tillandsia), are natural epiphytes. Their rosette shapes collect water, and they often produce stunning, colorful flower spikes. They are incredibly low-maintenance.
  • Orchids (Phalaenopsis, Cattleya): Forget the fussy reputation. Many orchid species are surprisingly tough and are born to live on trees. Attaching a Phalaenopsis (Moth Orchid) to a branch is a fantastic way to give it the air circulation it craves.
  • Bird’s Nest Ferns (Asplenium nidus): With their bright green, wavy fronds that form a “nest,” these ferns add a lush, tropical feel. They prefer shady, humid spots on the tree trunk.
  • Hoya (Wax Plant): While often grown as trailing houseplants, many Hoyas are epiphytic in their native habitats. Their waxy leaves and fragrant, star-shaped flowers are a delight when cascading down a tree branch.

Choosing the Right Host Tree

Just as important as the plant is the tree you choose as its home. The ideal host tree has rough, textured bark that gives the plant’s roots something to grip onto. A smooth, slippery trunk is much harder for a plant to anchor itself to.

Great Host Trees Include:

  • Oaks
  • Magnolias
  • Citrus Trees
  • Maples (older ones with rough bark)
  • Holly

Trees to Avoid:

  • Trees with smooth, slick bark like Birch or Crape Myrtle.
  • Trees that shed their bark frequently, such as Eucalyptus or Sycamore.
  • Pine trees and other conifers that produce a lot of resin or have very dense canopies that block all light.

Your Step-by-Step Guide: How to Growing Plants on Trees Safely

Alright, you’ve got your plant and you’ve picked the perfect tree. Now for the fun part! This process is simple, gentle, and most importantly, safe for both the plant and the tree. This is the core of our advice on how to growing plants on trees.

One rule above all: Never use nails, screws, or staples. Puncturing the bark creates a wound that can invite disease and pests, seriously harming your beautiful tree. We’ll use gentle, temporary ties that allow the plant to attach naturally over time.

  1. Step 1: Gather Your Supplies

    You don’t need much! Having everything ready makes the process smooth and easy.

    • Your chosen epiphyte (fern, orchid, etc.)
    • A mounting medium like sphagnum moss or coconut coir fiber.
    • Tying material like jute twine, fishing line, or strips of old nylon stockings (they’re stretchy and gentle!).
    • A bucket of water.
    • A spray bottle.

  2. Step 2: Prepare Your Plant and Moss

    Gently remove your plant from its nursery pot. If it’s packed in soil, carefully tease away as much of it as you can from the roots without breaking them. Remember, these roots are for gripping, not digging!

    Take your sphagnum moss and soak it in the bucket of water for about 20 minutes until it’s fully saturated. Then, grab a handful and squeeze out the excess water. You want it damp, not dripping wet.

  3. Step 3: Create a Moss “Pillow”

    Place the plant’s root ball in the spot you’ve chosen on the tree. Now, pack the damp sphagnum moss all around the roots, pressing it firmly against the bark. This moss pillow will hold moisture for the plant while its new roots get established.

  4. Step 4: Secure the Plant to the Tree

    Take your twine or fishing line and begin wrapping it around the moss ball, the plant’s base, and the tree trunk or branch. Go around several times in different directions to make sure it’s secure. The goal is to hold it snugly against the bark so it doesn’t wobble, but not so tight that you strangle the tree. Tie it off with a secure knot. The plant’s own roots will eventually take over this job!

The Ultimate Growing Plants on Trees Care Guide

You did it! The plant is mounted. Now, how do you keep it happy? The growing plants on trees care guide is simpler than you might think, as you’re working with nature, not against it.

Watering Best Practices

Forget your regular watering can. Epiphytes absorb water through their roots and sometimes their leaves. The key is to water the moss pillow until it’s saturated. In the beginning, you may need to water every few days, especially in hot, dry weather. Once established, you can often reduce this.

A gentle spray from a hose or a thorough misting with a spray bottle works perfectly. Aim for the root and moss ball. A good rule of thumb is to let the moss dry out slightly between waterings to prevent rot.

Feeding Your Vertical Garden

Since they don’t live in soil, epiphytes benefit from a little food during their growing season (spring and summer). Use a balanced liquid fertilizer, like a 20-20-20, diluted to quarter-strength. Too much fertilizer can burn their sensitive roots. Apply this with your watering every 2-4 weeks while the plant is actively growing.

Light and Location

Most epiphytes thrive in the dappled light they’d receive under a forest canopy. A spot on the tree that gets bright, indirect light is perfect. The north or east-facing side of a trunk is often a great choice, as it’s protected from the harsh afternoon sun. Direct sun can scorch their leaves.

Solving Common Problems with Growing Plants on Trees

Even with the best intentions, you might run into a hiccup or two. Don’t worry! Here are solutions to the most common problems with growing plants on trees.

Problem: My Plant is Drying Out Too Quickly

This is common in the beginning. Check that your moss ball is thick enough—it should be a generous pillow. You may need to increase your watering frequency or move the plant to a shadier, more protected spot on the tree.

Problem: The Plant Isn’t Attaching

Patience is a virtue here! It can take many months, sometimes up to a year, for a plant’s roots to fully grip the bark. Make sure your ties are still snug (but not tight) and give it time. As long as the plant looks healthy, it’s working on it.

Problem: Pests on My Epiphytes

The good air circulation on a tree helps prevent many pests. If you do see scale or mealybugs, you can often dislodge them with a strong spray of water. For a more persistent issue, a horticultural oil or insecticidal soap (always test on a small leaf first) can be very effective.

Problem: Yellowing Leaves

This is a classic sign of either too much direct sunlight or too much fertilizer. First, assess the light. Is it getting blasted by the afternoon sun? If so, consider moving it. If not, cut back on fertilizing. Remember, less is more with epiphytes.

Embracing Sustainable and Eco-Friendly Growing Plants on Trees

One of the most rewarding aspects of this gardening style is how it connects us to natural processes. This is the heart of sustainable growing plants on trees. You are creating a habitat, not just decorating.

By using natural, biodegradable materials like jute twine, you’re ensuring that once the plant has attached itself, the ties will simply break down and return to the earth. Using coconut coir and sphagnum moss as a base is another way to use sustainable, natural products.

This method is inherently water-wise, as you’re targeting a small area rather than soaking a large pot of soil. Setting up a rain barrel to collect water for your epiphytes is a fantastic next step for a truly eco-friendly growing plants on trees setup.

Frequently Asked Questions About Growing Plants on Trees

Will growing plants on trees harm my tree?

No, as long as you follow the best practices! By choosing true epiphytes (not parasitic plants) and using gentle ties instead of nails or screws, you are not harming the tree. The plants are simply using the tree for support, just as they would in the wild.

Can I grow any plant on a tree?

It’s best to stick to the epiphytes we’ve discussed, like orchids, bromeliads, and certain ferns. A regular potted plant that needs soil for its roots won’t survive this way. The key is choosing plants that are naturally adapted to this unique lifestyle.

How long does it take for a plant to attach itself to the tree?

This depends on the plant, the tree’s bark, and your climate. Generally, you can expect new roots to start exploring the bark within a few months, with a firm attachment taking anywhere from six months to a year or more. You’ll know it’s attached when you can gently tug on the plant and it feels solid.

What do I do in the winter?

This is a great question! If you live in a climate with freezing temperatures, tropical epiphytes like Phalaenopsis orchids or many bromeliads will not survive. For these plants, you can mount them on a piece of cork bark instead of directly on the tree. This allows you to hang them on the tree in the summer and easily bring them indoors for the winter.

Your Vertical Garden Awaits

There you have it—everything you need to step into the magical world of growing plants on trees. It’s a project that combines creativity, a love for nature, and a bit of gardening ingenuity.

You’re not just adding a plant; you’re creating a living sculpture that will grow and change with the seasons, adding character and life to a previously overlooked part of your garden. It’s a conversation starter and a source of constant joy.

So go ahead, find that perfect spot on an old oak, choose a beautiful Staghorn Fern or a vibrant orchid, and start your vertical gardening adventure today. Happy growing!
