Taking care of your plants during hot weather requires careful planning and execution. Here are some essential tips to ensure your plants not only survive but flourish in the heat of British Columbia:

Choosing Heat-Tolerant Plants

Selecting the right plants for your hot weather garden is crucial. Look for species that are known to thrive in high temperatures and can withstand the intense sun of British Columbia. Here are some fantastic heat-tolerant options to consider:

  1. Drought-Resistant Succulents: Succulents, such as Cacti, in the Cactaceae family, and Sedum, have adapted to thrive in arid conditions and are perfect for hot weather gardening. Their fleshy leaves store water, making them highly resistant to drought.
  2. Native Wildflowers: Native wildflowers like Lupines and Indian Paintbrush are well-suited to British Columbia’s climate. They have evolved to withstand the local heat and can add vibrant colors to your garden.
  3. Herbs: Many herbs, including rosemary, thyme, and oregano, love the heat and can add flavor to your dishes. Plant them in well-drained soil and enjoy the aromatic benefits of these heat-tolerant herbs.
  4. Ornamental Grasses: Ornamental grasses, like Miscanthus and Pennisetum, not only bring beauty to your garden but also thrive in hot weather. Their feathery plumes sway gracefully in the summer breeze.

Remember to research and choose plants that are specifically suited to your region in British Columbia. This way, you’ll ensure they are well-adapted to the local climate and have a higher chance of thriving.

Soil Preparation and Mulching

Proper soil preparation is key to creating a healthy foundation for your plants. Follow these steps to prepare your soil for hot weather gardening:

  1. Amend Your Soil: Before planting, enrich your soil with organic matter like compost or well-rotted manure. This improves soil structure, retains moisture, and provides essential nutrients to your plants.
  2. Mulch, Mulch, Mulch: Applying a layer of organic mulch around your plants is a game-changer for hot weather gardening. Mulch helps retain moisture, suppresses weeds, and regulates soil temperature, keeping your plants cool during scorching days.
  3. Choose the Right Mulch: Opt for organic mulches like wood chips, straw, or shredded leaves. These materials not only improve soil fertility as they decompose but also provide an attractive aesthetic to your garden.

Efficient Watering Techniques

Watering your plants correctly is crucial for their survival in hot weather. Follow these tips to ensure your plants receive adequate hydration without wasting water:

  1. Water Deeply and Infrequently: Instead of frequent shallow watering, give your plants a deep soak. This encourages the development of deep root systems, making them more resilient to drought.
  2. Water in the Morning: Water your plants early in the morning to minimize water loss through evaporation. This allows the foliage to dry during the day, reducing the risk of fungal diseases.
  3. Use Drip Irrigation: Consider installing a drip irrigation system, which delivers water directly to the plant roots. This method reduces water wastage and ensures efficient hydration.
  4. Install Rain Barrels: Collect rainwater in barrels and use it to water your plants. This eco-friendly approach conserves water and reduces your reliance on municipal water supplies.

Providing Adequate Shade

Protecting your plants from direct sunlight is crucial during hot weather. Consider these strategies to provide shade for your garden:

  1. Use Shade Cloth: Install shade cloth over delicate plants or create temporary shade structures using mesh fabric. This filters out excess sunlight while still allowing airflow.
  2. Plant Companion Trees: Choose companion trees that provide shade without competing for resources with your garden plants. Deciduous trees, like the Japanese maple, offer shade in summer and allow sunlight through in winter.
  3. Utilize Trellises and Arbors: Grow climbing plants like grapes or flowering vines on trellises or arbors. These structures provide shade and add vertical interest to your garden.

Regular Maintenance and Pest Control

Keeping up with regular maintenance and pest control ensures your plants stay healthy and resilient in hot weather. Follow these tips to stay ahead of potential problems:

  1. Monitor Soil Moisture: Check the moisture level of your soil regularly. Use a moisture meter or simply stick your finger into the soil to assess its dryness. Adjust your watering accordingly.
  2. Inspect for Pests: Regularly inspect your plants for signs of pests like aphids, spider mites, or whiteflies. If detected early, you can take appropriate measures such as using organic insecticides or introducing beneficial insects.
  3. Deadhead Spent Flowers: Remove faded flowers regularly to encourage new blooms and prevent the plant from diverting energy into seed production.
  4. Weed Control: Keep your garden free from weeds that compete with your plants for water and nutrients. Regularly remove weeds by hand or use mulch to suppress their growth.

Now that we’ve covered essential hot weather gardening tips, let’s address some frequently asked questions to provide further clarity and insights.


Q: How often should I water my plants during hot weather?

A: The frequency of watering depends on various factors like plant type, soil type, and weather conditions. As a general guideline, aim to water deeply once or twice a week rather than shallow watering daily. However, always check the moisture level of the soil before watering.

Q: Can I grow vegetables in hot weather?

A: Absolutely! Many vegetables thrive in hot weather, such as tomatoes, peppers, eggplants, and beans. Just ensure they receive adequate water and sun protection, and you’ll enjoy a bountiful harvest.

Q: How can I protect my plants from overheating in containers?

A: Container plants are more susceptible to overheating. To protect them, place containers in shaded areas, use light-colored pots that reflect heat, and mulch the soil surface to regulate temperature and retain moisture.

Q: Should I fertilize my plants more during hot weather?

A: While some plants benefit from a light application of balanced fertilizer during the growing season, it’s crucial not to over-fertilize during hot weather. Excessive fertilization can lead to excessive foliage growth, making plants more vulnerable to heat stress.

Q: Are there any low-maintenance plants for hot weather gardening?

A: Yes! Low-maintenance plants like lavender, yarrow, and sedum are excellent choices for hot weather gardening. They require minimal care, are drought-tolerant, and add beauty to your garden with their unique textures and colors.

Q: Can I use shade-loving plants in hot weather gardening?

A: While shade-loving plants prefer less direct sunlight, many can still tolerate partial shade or filtered sunlight in hot weather. Research and select shade-tolerant plants suited to your region’s specific climate.


With these hot weather gardening tips in mind, you’re well-equipped to create a thriving garden in the heat of British Columbia. Remember to choose heat-tolerant plants, prepare your soil, implement efficient watering techniques, provide adequate shade, and stay on top of maintenance and pest control. By taking these steps, you’ll be rewarded with a lush, vibrant garden even during scorching summers. Happy gardening!
