How to Keep Your Plants Thriving in Summer Heat
Now that you’ve chosen your favorite container plants for summer, let’s talk about summer care for container plants. These tips will help you keep your garden thriving, even when temperatures soar.
Watering Tips for Hot Weather
Watering container plants in summer can be tricky, but here’s how to get it right:
- Check soil moisture with the finger test: If the top inch is dry, it’s time to water. For zinnias and petunias, this might mean watering every 2–3 days in 90°F heat, but let portulaca dry out between waterings.
- Water in the morning to reduce evaporation and prevent fungal issues.
- Use a watering can with a narrow spout to target the soil, not the leaves.
Fertilizing for Summer Growth
To keep your plants blooming, fertilize every 4–6 weeks with a balanced 10-10-10 fertilizer. If you prefer organic options, try compost tea—it’s eco-friendly and perfect for your sustainable gardening goals.
Protecting Plants from Heat Stress
When temperatures climb above 95°F, your plants might need extra care:
- Move pots to partial shade during the hottest part of the day (usually 2–4 PM).
- Add a layer of mulch (like bark or straw) to the soil surface to retain moisture.
- Mist foliage lightly in the evening to cool plants down (but avoid overwatering).
Pest Control for Summer Container Plants
Summer heat can attract pests like aphids and spider mites. Here’s how to handle pest control for summer container plants naturally:
- Spray plants with neem oil or a soapy water solution (1 tsp dish soap per quart of water).
- Plant marigolds nearby—they naturally repel pests.
- To prevent powdery mildew, improve air circulation by spacing pots a few inches apart.
Bonus: Create a Pollinator-Friendly Summer Container Garden
Want to attract bees, butterflies, and hummingbirds to your patio? A pollinator-friendly container garden in summer is a great way to teach your kids about nature while adding beauty to your space.
- Choose Pollinator-Friendly Plants: Zinnias, lantanas, and salvia are all on our list and loved by pollinators.
- Tips: Avoid pesticides, plant in clusters to make it easier for pollinators to find, and add a small water dish with pebbles for bees to drink from.
- Why It Matters: Supporting pollinators helps your local ecosystem, and it’s a fun way to get your kids involved in gardening.
