Training plants to grow horizontally is a smart way to maximize your garden’s potential, especially in small spaces. This simple technique can lead to healthier plants and bigger harvests. Whether you have sprawling squash or climbing tomatoes, guiding them sideways opens up a world of possibilities. It’s easier than you might think, and you don’t need any special skills to get started.
Horizontal training, often called espalier for fruit trees or simply trellising for veggies, controls plant shape. It improves air circulation and sun exposure for every leaf. This method helps prevent disease and makes pest checks a breeze. You’ll find that fruits and vegetables become easier to pick, and your garden will look neat and intentional.
Training Plants To Grow Horizontally
This core method involves gently directing plant growth along a flat plane. Instead of letting plants grow tall and bushy, you guide their main stems and branches sideways. You’ll use supports like trellises, fences, or simple wires. The key is to start early and be consistent with your guidance as the plant grows.
Why Train Plants Horizontally?
The benefits are clear and immediate. Here’s what you can expect:
- More Sunlight: Leaves are spaced out, reducing shade on lower parts. This can lead to better photosynthesis and sugar production in fruits.
- Better Airflow: Open structure minimizes damp, stagnant air where fungal diseases thrive.
- Space Efficiency: Perfect for patios, balconies, and small yard gardens. You grow up, or in this case, across, instead of out.
- Easier Maintenance: Pruning, watering, and harvesting are all done at a comfortable height. No more bending or straining.
- Higher Yields: With improved health and energy distribution, many plants will produce more fruit.
Best Plants for Horizontal Training
Not all plants are ideal candidates. Focus on vining, climbing, or flexible-stemmed varieties. Here are the top choices:
- Cucumbers & Melons: Their long vines are natural climbers. Training them keeps fruit clean and straight.
- Tomatoes (Indeterminate): These keep growing all season. Horizontal training on a strong trellis is perfect for them.
- Pole Beans & Peas: They instinctively grab onto supports. A horizontal netting system works wonders.
- Squash & Pumpkins: Use slings or nets to support heavy fruit when training vines sideways.
- Fruit Trees (Apples, Pears, Figs): Espalier is the classic horizontal training for trees, great for fences and walls.
- Grape Vines: Traditionally trained on horizontal wires (cordon system) for optimal fruiting.
- Blackberries & Raspberries: Using a T-trellis to separate canes improves health and harvest.
Simple Methods and Supports You Can Build
You don’t need expensive equipment. Many supports use common materials you might already have.
The Single Wire or Fence Method
This is the simplest approach. Run a sturdy wire or use an existing fence line. As the plant grows, gently tie its main stem to the wire using soft plant ties, cloth strips, or velcro ties. Always tie loosely to allow for stem growth. This method is excellent for tomatoes, peas, and beans in there first season.
The Horizontal Trellis Netting
Attach plastic or jute netting to posts or a frame. Plants will weave through the grid naturally with a little help. This provides excellent support for cucumbers, melons, and vining flowers like morning glories. The netting creates a large, flat growing surface.
The “Florida Weave” for Tomatoes
A popular, low-cost field technique. Drive stakes between every other plant. Weave twine back and forth between the stakes, catching the tomato plants in between. Add new levels of twine as the plants grow taller. It effectively creates a horizontal support wall.
Cordon Espalier for Fruit Trees
This is a multi-year project but very rewarding. Start with a young, flexible tree against a wall or fence with horizontal wires. Select a few strong side branches and tie them to the wires, pruning away unwanted growth. The classic pattern is a simple “T” shape or tiered horizontal arms.
Step-by-Step Guide to Training
Follow these steps for success with most vining vegetables.
- Install Supports Early: Put your trellis, wires, or fence in place before or right after planting. Disturbing roots later can harm the plant.
- Begin Gentle Guidance: When the main stem is long enough to reach the support, loosely attach it. Don’t force it; the plant should be relaxed.
- Use the Right Ties: Never use wire, string, or zip ties directly on stems. Use soft materials that won’t cut into the bark as it expands.
- Prune Strategically: Remove some leaves and side shoots (suckers on tomatoes) that grow toward the front or back. This maintains the flat, horizontal form.
- Check and Adjust Weekly: Plants grow fast! Make a habit of gently tucking in new growth and adding new ties where needed. This regular attention is what makes the method effective.
- Support Heavy Fruit: For squash or melons, create slings from old t-shirts or net bags to attach to the trellis, taking weight off the vine.
Common Mistakes to Avoid
Even simple methods can go a little wrong. Here’s what to watch for:
- Starting Too Late: Trying to train a thick, woody stem will break it. Start when growth is young and flexible.
- Tying Too Tight: This is the number one error. Always leave room for the stem to thicken. A tight tie will strangle the plant.
- Using Abrasive Materials: Wire or rough string will damage the plant’s vascular system, restricting water and nutrient flow.
- Neglecting Pruning: If you don’t remove some inward growth, the plant will become a dense thicket, losing all the benefits of airflow and light.
- Inadequate Support: A flimsy trellis will collapse under the weight of a mature plant. Ensure your structure is strong and deeply anchored.
Care for Horizontally Trained Plants
Their needs change slightly when trained. Water at the base since the foliage is spread out; overhead watering might not reach the roots effectively. Fertilize as usual, but you may find they use water more efficiently. Pest inspection is easier, but sun exposure on fruit can sometimes lead to scalding in extreme heat. A little afternoon shade cloth can help in very hot climates.
FAQ
Can I train any plant to grow horizontally?
Not all plants respond well. It’s best for vining plants and those with flexible new growth. Avoid it with stiff-stemmed, bush-type plants.
What is the easiest plant to start with?
Pole beans or peas are the easiest. They naturally climb and adapt quickly to horizontal netting or a wire fence.
How do you train a plant to grow sideways?
You gently attach the main stem to a horizontal support and continue to secure new growth along that plane, pruning any growth that goes forward or backward.
Is horizontal training good for all tomatoes?
It’s excellent for indeterminate (vining) tomatoes. Determinate (bush) tomatoes have a fixed size and aren’t suitable for this kind of training.
Can I use this method indoors?
Absolutely! A small horizontal trellis on a wall or a wire grid in front of a sunny window can work for indoor cucumbers or cherry tomatoes.
When is the best time to start training?
Begin when the plant is young, usually a few weeks after transplanting, once it has established some new growth.
Training plants to grow horizontally is a fundamental gardening skill that yields impressive results. With a simple support and a few minutes of care each week, you can create a productive, beautiful, and manageable garden. The initial effort pays off all season long with healthier plants and an abundant, easy-to-reach harvest. Give it a try with a few cucumber or tomato plants this year—you’ll likely be amazed by the difference it makes.
