Growing plants on terraces and balconies can be an incredibly rewarding experience, transforming your outdoor space into a lush, green oasis. However, high wind terraces present unique challenges that many gardeners overlook. At Idyl, we understand that not all plants are created equal when it comes to withstanding strong winds. In this comprehensive guide, we'll explore which plants you should avoid growing in high wind terraces and provide you with practical solutions to help you create a thriving garden despite challenging weather conditions.
Understanding the Impact of Wind on Terrace Plants
Before diving into specific plants to avoid, it's essential to understand how wind affects plant growth and survival. Wind on high terraces isn't just a minor inconvenience—it can be a significant stressor that impacts every aspect of plant development.
How Wind Damages Plants
Wind causes multiple types of damage to plants. Physical damage is the most obvious, where strong gusts can break branches, snap stems, and tear leaves. This mechanical damage not only makes plants look unsightly but also creates open wounds that are susceptible to disease and pest infestations. When leaves are torn or damaged, they lose their ability to photosynthesize efficiently, reducing the plant's energy production and overall health.
Beyond physical damage, wind also causes physiological stress. Strong winds increase transpiration rates, meaning plants lose water through their leaves much faster than they can absorb it through their roots. This is particularly problematic on terraces where soil dries out quickly anyway due to increased sun exposure and drainage. Plants subjected to constant wind stress may develop stunted growth, yellowing leaves, and weakened root systems.
Wind can also interfere with pollination and flowering. Many plants rely on insects for pollination, and strong winds can disrupt insect activity. Additionally, wind can cause flowers to drop prematurely, reducing fruit and seed production. For gardeners hoping to harvest vegetables or enjoy abundant blooms, this is a significant concern.
Terrace Wind Plant Damage: A Unique Challenge
Terraces and rooftops experience wind differently than ground-level gardens. Wind speeds increase with elevation, and buildings can create wind tunnels that accelerate air movement even further. This means that plants on high terraces face more intense and consistent wind exposure than their ground-level counterparts. Understanding this unique environment is crucial for selecting appropriate plants.
Plants to Avoid in High Wind Terraces
Now that we understand the challenges, let's explore specific plants that struggle in high wind conditions. These wind sensitive plants balcony gardeners should definitely avoid or handle with extreme care.
Tall, Top-Heavy Plants
Plants with tall, slender stems and heavy foliage at the top are particularly vulnerable to wind damage. These plants have a high center of gravity, making them prone to toppling over or snapping at the base.
Fuchsias are beautiful flowering plants with delicate, drooping flowers, but they're notoriously sensitive to wind. Their thin stems and heavy flower clusters make them susceptible to breaking, and wind can damage the delicate blooms. If you love fuchsias, you'll need to provide substantial protection and support structures.
Hollyhocks are another tall plant that struggles in windy conditions. These plants can reach heights of six feet or more, and their tall, slender stems simply cannot withstand strong winds without significant support. The large flowers are also easily damaged by wind, reducing their ornamental value.
Delphiniums are prized for their tall spikes of blue, purple, or pink flowers, but they're extremely wind-sensitive. These plants require staking even in moderate wind conditions, and on high terraces, they're likely to be damaged regardless of support measures.
Sunflowers, while hardy in many respects, can be problematic on terraces due to their height and the weight of their flower heads. Tall varieties are particularly susceptible to wind damage and may require extensive staking and support.
Delicate Flowering Plants
Some plants are simply too delicate to withstand wind exposure. Their flowers and foliage are easily damaged, and the stress of constant wind can prevent them from flowering altogether.
Orchids are among the most delicate plants you can grow. These tropical plants have thin, fragile leaves and delicate flowers that are easily damaged by wind. Wind can also disrupt the humidity levels that orchids require, making them extremely challenging to grow on exposed terraces.
Peonies produce beautiful, full flowers, but these blooms are heavy and easily damaged by wind. Strong gusts can shatter the delicate petals, and the weight of the flowers combined with wind stress can cause stems to break.
Roses, particularly hybrid tea roses with their large, heavy blooms, struggle in windy conditions. The delicate petals are easily bruised and damaged, and wind can reduce the plant's ability to produce quality flowers. While some rose varieties are more wind-tolerant than others, most benefit from wind protection.
Dahlias produce stunning, intricate flowers, but these blooms are vulnerable to wind damage. The heavy flowers combined with wind stress can cause stems to snap, and the delicate petals are easily damaged by strong gusts.
Clematis is a beautiful climbing plant, but many varieties are sensitive to wind. The delicate flowers are easily damaged, and wind can prevent the plant from flowering properly. Additionally, the thin stems can be snapped by strong gusts.
Shallow-Rooted Plants
Plants with shallow root systems struggle on terraces because they cannot anchor themselves securely against wind. Additionally, shallow roots dry out quickly in the intense sun and wind exposure typical of terraces.
Begonias have shallow root systems and are sensitive to both wind and drought. These plants prefer sheltered conditions and consistent moisture, making them poor choices for exposed terraces.
Impatiens are another shallow-rooted plant that struggles in windy conditions. These delicate plants prefer sheltered, moist environments and will quickly deteriorate on exposed terraces.
Petunias, while generally hardy, have relatively shallow roots and can be uprooted or damaged by strong winds. They also prefer consistent moisture, which is difficult to maintain on exposed terraces.
Marigolds are often recommended as easy plants for beginners, but they're not ideal for high wind terraces. Their shallow roots and relatively delicate stems make them vulnerable to wind damage.
Tender Perennials and Annuals
Many tender perennials and annuals are simply too delicate for exposed terrace conditions. These plants often come from protected environments and lack the structural strength to withstand wind stress.
Zinnias are popular annual flowers, but they're sensitive to wind. Strong winds can damage the flowers and cause the plants to become stunted and misshapen.
Cosmos are delicate annual flowers with thin stems that break easily in wind. While they're generally easy to grow, they're not suitable for exposed terraces.
Snapdragons have tall, slender stems that are easily damaged by wind. These plants require staking and protection even in moderate wind conditions.
Verbena is a delicate annual that struggles in windy conditions. The thin stems and small flowers are easily damaged, and wind stress can prevent the plant from flowering prolifically.
Large-Leaved Plants
Plants with large leaves present a large surface area to the wind, making them more susceptible to damage and water loss. The large leaves can be torn, and the plant's structure may not be strong enough to support them in windy conditions.
Hibiscus plants have large, delicate leaves and flowers that are easily damaged by wind. While some hibiscus varieties are relatively hardy, most struggle on exposed terraces.
Bougainvillea produces beautiful flowers, but the plant has large leaves and a somewhat brittle structure that makes it vulnerable to wind damage. The delicate flowers are also easily damaged by strong gusts.
Caladiums are grown primarily for their large, colorful leaves. These leaves are easily torn by wind, and the plants prefer sheltered, humid conditions that are difficult to provide on exposed terraces.
Elephant ears (Colocasia and Alocasia) have enormous leaves that are easily damaged by wind. These plants require sheltered conditions and consistent moisture, making them poor choices for terraces.
Hostas are shade-loving plants with large leaves that are easily torn by wind. While they're generally hardy, they're not suitable for exposed, windy locations.
Rooftop Gardening Issues with Specific Plants
Certain plants present particular challenges when grown on rooftops and high terraces due to their specific growing requirements.
Vegetables like tomatoes, peppers, and eggplants can be grown on terraces, but many varieties struggle with wind. Tall indeterminate tomato varieties are particularly problematic, as they require extensive staking and support. Wind can damage the delicate flowers, reducing fruit set, and can cause the plants to become stressed and susceptible to disease.
Herbs like basil and cilantro are sensitive to wind and prefer sheltered conditions. While hardy herbs like rosemary and thyme can tolerate wind better, tender herbs struggle on exposed terraces.
Fruit trees and berry bushes are generally not suitable for terraces due to their size and wind sensitivity. Dwarf varieties might work with substantial support, but they're challenging to grow successfully.
Climbing plants like ivy and jasmine can work on terraces if properly supported, but many varieties are sensitive to wind and may not establish well in exposed conditions.
Plant Protection Wind Strategies
If you're determined to grow wind-sensitive plants on your terrace, there are several strategies you can employ to protect them from wind damage.
Windbreaks and Barriers
Creating physical barriers to reduce wind speed is one of the most effective strategies. Solid barriers like walls, fences, or screens can significantly reduce wind speed in their lee. However, solid barriers can create turbulent wind patterns on their downwind side, so semi-permeable barriers are often more effective.
Lattice screens, shade cloth, and specially designed windbreak fabrics can reduce wind speed while allowing some air circulation. These barriers should be positioned to protect your plants without creating stagnant air conditions that can lead to disease problems.
At Idyl, we recommend installing windbreak structures on the windward side of your terrace. These structures should be tall enough to protect your plants and positioned to minimize turbulence.
Staking and Support Systems
Proper staking and support can help prevent wind damage to tall plants. Use sturdy stakes or cages that are appropriate for the plant's size and weight. Tie plants to stakes using soft materials that won't damage the stems.
For particularly tall or heavy plants, consider using multiple support points rather than a single stake. This distributes the stress more evenly and provides better protection against wind damage.
Grouping Plants
Grouping plants together can provide mutual protection. Taller plants can shelter shorter, more delicate plants from wind. This strategy also helps create a more cohesive garden design and can improve humidity levels around the plants.
Selecting Appropriate Containers
Using heavy containers filled with quality potting soil can help prevent plants from being blown over. Avoid lightweight plastic pots on terraces; instead, use ceramic, concrete, or other heavy materials. Ensure containers have adequate drainage holes to prevent waterlogging.
Soil Amendments and Mulching
Proper soil preparation is crucial for helping plants withstand wind stress. Use high-quality potting soil that retains moisture while still providing good drainage. Adding organic matter like compost can improve the soil's water-holding capacity.
Mulching around plants helps retain soil moisture and keeps roots cooler, reducing water stress. Use organic mulches like bark chips or straw, but keep mulch away from plant stems to prevent rot.
Regular Watering and Fertilizing
Plants stressed by wind require consistent care. Water regularly to ensure plants don't become drought-stressed, which compounds the effects of wind damage. Use a drip irrigation system or soaker hoses to deliver water directly to the soil, reducing water loss to evaporation.
Fertilize regularly to support plant growth and recovery from wind damage. Use a balanced fertilizer or one specifically formulated for the type of plants you're growing.
Wind-Tolerant Alternatives for High Terraces
Rather than struggling with wind-sensitive plants, consider growing plants that naturally tolerate wind conditions. These plants have evolved to withstand wind stress and will thrive on your terrace.
Ornamental Grasses
Ornamental grasses are excellent choices for windy terraces. Their flexible stems bend with the wind rather than breaking, and their fine texture creates movement that's visually appealing. Varieties like fountain grass, blue fescue, and feather reed grass are all wind-tolerant and add texture and interest to terrace gardens.
Shrubs and Small Trees
Dwarf shrubs and small trees can provide structure and year-round interest on terraces. Wind-tolerant varieties include dwarf conifers, Japanese maple (in sheltered spots), and various ornamental shrubs. These plants develop strong root systems and sturdy stems that can withstand wind.
Perennials
Many perennials are naturally wind-tolerant. Coneflowers, black-eyed Susans, salvia, and catmint are all hardy perennials that thrive in windy conditions. These plants develop strong root systems and sturdy stems that can withstand wind stress.
Groundcovers
Low-growing groundcovers are naturally wind-tolerant because they have a low profile that reduces wind exposure. Creeping thyme, sedums, and other groundcovers can create attractive, low-maintenance gardens on terraces.
Succulents
Succulents are excellent choices for windy terraces. Their thick, fleshy leaves and compact growth habits make them naturally wind-tolerant. Sedums, echeveria, and other succulents are also drought-tolerant, making them ideal for the challenging conditions on terraces.
Herbs
Hardy herbs like rosemary, thyme, oregano, and sage are wind-tolerant and can provide both culinary and ornamental value. These Mediterranean herbs are adapted to windy conditions and prefer the well-drained soil typical of terraces.
Creating a Thriving Terrace Garden Despite Wind Challenges
With proper planning and plant selection, you can create a beautiful, thriving garden on your terrace, even in high wind conditions.
Assessing Your Terrace's Wind Conditions
Before selecting plants, assess your terrace's specific wind conditions. Note the direction of prevailing winds, the intensity of wind exposure, and any natural or built windbreaks. This information will help you select appropriate plants and position them effectively.
Designing Your Terrace Garden
Plan your garden layout to take advantage of natural windbreaks and to create microclimates that protect sensitive plants. Position taller plants on the windward side to shelter shorter plants. Group plants with similar water and light requirements together for easier maintenance.
Soil Preparation
Prepare your soil carefully before planting. Use high-quality potting soil mixed with compost to improve water retention and nutrient content. Ensure adequate drainage to prevent waterlogging, which can lead to root rot and disease.
Regular Maintenance
Regular maintenance is crucial for keeping your terrace garden healthy. Water consistently, fertilize regularly, and monitor plants for signs of stress or disease. Prune plants as needed to maintain their shape and remove damaged growth.
Seasonal Considerations
Be aware of seasonal wind patterns in your area. Some regions experience stronger winds during certain seasons, and you may need to adjust your care practices accordingly. In winter, provide additional protection for tender plants, and in spring, watch for strong winds that can damage new growth.
