Water Wisely: Hot air dries soil faster, but these desert-adapted plants are prone to root rot. Always check the soil before watering; it’s better to underwater than overwater. Water in the morning to reduce evaporation.
Monitor the Light: While these plants love sun, intense summer light through a south-facing window can still cause leaf scorch. Consider using sheer curtains to filter the harshest midday rays.
Good Airflow is Key: Proper ventilation helps regulate temperature and keeps your plant comfortable. Avoid placing plants in the direct path of cold A/C drafts.
Hold the Fertilizer: Avoid fertilizing stressed plants during extreme heatwaves, as they can’t absorb the nutrients effectively and it can cause more stress.
Boost Humidity (If Needed): While most on this list prefer dry air, you can increase humidity for certain plants by grouping them together or using a humidifier. 👉 Learn more about plant humidity needs.
❓ Frequently Asked Questions
What are the best houseplants for a hot, south-facing window?
For a hot and sunny spot, you’ll want plants that are native to desert or arid environments. The Desert Rose (Adenium obesum), Ponytail Palm (Beaucarnea recurvata), and various Cacti are excellent choices as they thrive in direct sunlight and high heat. Other succulents, like the Jade Plant (Crassula ovata) and Aloe Vera, also perform very well in these conditions.How often should I water my heat-loving plants in the summer?
During hot summer months, you will likely need to water more frequently as the soil dries out faster. However, it’s crucial not to overwater, as many heat-tolerant plants like succulents are prone to root rot. Instead of following a strict schedule, check the soil every few days. A good rule of thumb is to water thoroughly only when the top one to two inches of soil are completely dry. 👉 For more tips, see our Watering Guide.Can heat-tolerant plants still get sunburned?
Yes, absolutely. Even sun-loving plants can get scorched if the sunlight is too intense, especially when magnified through a window during the hottest part of the day. Signs of sunburn include white, yellow, or brown patches on the leaves. If you notice this, consider moving the plant a few feet back from the window or filtering the light with a sheer curtain. 👉 Learn to spot the signs in our guide to Sunburn and Leaf Scorch.Will my air conditioner harm my houseplants?
While it helps control the heat, air conditioning can be a problem for plants. The cold drafts can shock them by freezing plant cells, and the A/C removes humidity from the air, which can stress even desert plants. It’s best to keep your plants away from the direct airflow of an A/C vent. If the air is very dry, grouping plants together can help create a more humid microclimate.What are the signs of heat stress in my indoor plants?
Common signs of heat stress include wilting or drooping leaves, even when the soil is moist. You might also notice the leaves starting to curl, turn yellow, or develop dry, crispy brown edges. In some cases, a plant might drop its leaves to conserve water.Is it okay to fertilize my plants during a heatwave?
It is best to avoid fertilizing plants during periods of extreme heat. When a plant is already stressed, it can’t properly absorb the nutrients, and the fertilizer salts can build up and burn the roots, causing more harm. Wait until the temperature cools down before resuming your regular feeding schedule.What's the best heat-tolerant plant for a low-light room?
The ZZ Plant (Zamioculcas zamiifolia) and the Snake Plant (Sansevieria trifasciata) are your best options. Both are exceptionally tolerant of high temperatures and can adapt to low-light conditions where other heat-lovers would struggle. They are known for being nearly indestructible and are great choices for rooms that don’t get much direct sun.Do some houseplants actually help cool down a room?
Yes, they can have a minor cooling effect. Through a process called transpiration, plants release moisture vapor from their leaves, which can slightly cool the surrounding air. Plants with larger leaves, like the Rubber Plant or various Palms, tend to be more effective at this, acting as natural humidifiers. However, they will not replace an air conditioner.Can I move my indoor plants outside during the summer?
Many houseplants enjoy a summer vacation outdoors, but you must acclimate them slowly. Don’t move them directly into full, hot sun, as this will cause shock and severe sunburn. Start by placing them in a fully shaded spot for a few days, then gradually move them into areas with more light over a week or two.Besides watering, what can I do to protect my plants from extreme heat?
To help your plants cope with a heatwave, ensure there is good air circulation by using a fan-just don’t point it directly at the plants. You can also group plants together to raise the local humidity. Using light-colored pots can also help, as dark pots absorb more heat and can bake the roots. Moving plants a few inches away from hot window glass can also prevent scorched leaves.🪴 See also 🪴
