If you’re looking to add some greenery to your outdoor space, consider a wall garden! Not only does it provide visual interest but also makes use of vertical space. In this article, we’ll explore how to create a thriving wall garden in hot and sunny areas.

Why choose plants for hot walls?

Hot walls that receive direct sunlight are often challenging areas for gardening. However, with proper plant selection, soil preparation, and maintenance techniques, these seemingly inhospitable areas can be transformed into thriving gardens.

Benefits of hot wall gardening

In addition to aesthetics, wall gardens have numerous benefits like purifying the air, reducing energy consumption, lowering noise levels, providing habitat for wildlife, and even increasing property value.

Best Plants for Hot Walls

It’s essential to choose plants that are eco-friendly, low-maintenance, drought-tolerant, and suitable for the specific conditions of your site. Here are few suitable plants for wall gardens:

1. Succulents

Succulents are a popular choice for wall gardens because they're easy to care for, require minimal water, and come in various shapes and colors. They also thrive in partial shade and full sun, making them ideal for hot wall gardening.

2. Climbing Plants

Climbing plants are an excellent option if you want to add height and texture to your wall garden. Some climbing vines like trumpet vine, clematis, and honeysuckle can tolerate extreme heat and drought-like conditions.

3. Mediterranean Herbs

Mediterranean herbs such as thyme, rosemary, lavender, and sage thrive in hot and dry environments. They not only look stunning but also provide aromatic fragrance when you brush against them.

How to Care For Plants on Hot Walls

Keeping plants healthy on a hot wall requires dedication and patience. Here are some tips to care for plants in your wall garden:

Choosing the right soil and watering techniques

Use well-draining soil that holds moisture and nutrients and doesn’t compact quickly. Ensure proper drainage by adding sand or mulch. As for watering, it's best to give deep and less frequent watering rather than shallow frequent watering to promote deeper roots.

Regular maintenance tips

Regularly prune and remove dead plant material to prevent pests and disease from spreading. Use organic fertilizers to promote healthy growth and nutrient uptake.

Protecting plants from extreme heat and cold

Cover newly planted plants with shade cloth or burlap until they get established. Adding a layer of mulch around the planting area can also help retain moisture and regulate soil temperature. Covering sensitive plants during frost or freezing temperatures is equally important.

Design Tips for Wall Gardens

Wall gardens can be an extension of your indoor décor and add drama to outdoor spaces. Here are some design ideas to help you create the perfect wall garden:

Creating a vertical garden

Use hanging pots and baskets or special plant hangers to create a broad surface on the wall. You can plant any small-sized plants like herbs, ferns, and annual flowering plants.

Mixing plant textures and colors

Combine various shades of greens and different textures to add interest to the wall. Mix climbers, trailings, and upright plants together to create a focal point.

Maximizing garden space

Create a narrow or space-saving garden by planting plants in series, look for compact or dwarf varieties where possible.

Incorporating hardscaping elements

Add planters that match the wall material, like plastic or clay pots, to blend with the existing decor. You may also consider installing shelves directly on the wall.

Creating a hot wall garden is not as challenging as it seems if done correctly. With the right plants, soil preparation, and maintenance techniques, a beautiful, thriving outdoor space can be created. Wall gardens offer numerous benefits, so why not try it yourself?
