Summer brings longer days, warmer temperatures, and intense sunlight, which can be both beneficial and challenging for houseplants. While some plants thrive in bright, warm conditions, others struggle with heat stress, increased evaporation, and the risk of pests.
Knowing how to care for your houseplants during the summer months ensures they stay healthy, hydrated, and thriving. From proper watering techniques to managing humidity and protecting plants from heat, there are several steps you can take to keep your indoor garden in top shape.
In this guide, we’ll explore how to help your houseplants this summer, common summer plant problems, and expert tips to keep them happy.
Why Do Houseplants Need Extra Care in Summer?
Summer can be a stressful time for houseplants, especially those that are sensitive to heat and dry air. With increased sunlight and higher temperatures, plants lose moisture more quickly, leading to wilting and dehydration if not properly cared for.
Humidity levels often drop in air-conditioned homes, causing dry leaf tips and slowed growth in moisture-loving plants. Increased warmth can also encourage pests like spider mites and aphids, which thrive in hot, dry conditions.
By making small seasonal adjustments, you can help your houseplants thrive throughout the summer and prevent common issues like sunburn, dehydration, and pest infestations.
How to Help Your Houseplants Thrive in Summer
With the right care, houseplants can flourish during the summer months. Here are essential tips to keep them healthy, hydrated, and strong.
1. Adjust Your Watering Routine
Watering needs change as temperatures rise. Houseplants lose moisture faster in warm weather, so they often require more frequent watering. However, overwatering can lead to root rot, so it’s essential to strike the right balance.
Check the soil every few days by inserting your finger an inch deep. If it feels dry, it’s time to water. Use room-temperature water to avoid shocking the roots.
Plants in terra cotta pots and hanging baskets dry out faster than those in plastic or ceramic pots. Consider watering early in the morning when temperatures are cooler to help plants absorb moisture efficiently.

2. Protect Plants from Harsh Sunlight
Summer sun can be intense, causing leaf burn and overheating. While some houseplants love bright light, others, like peace lilies and ferns, prefer indirect or filtered sunlight.
If your plant’s leaves show signs of yellowing, browning, or scorched spots, move them away from direct sunlight or place a sheer curtain over windows to diffuse the light.
Rotate plants every few days to ensure even exposure and prevent one side from getting too much sun. If possible, group plants together to create a microclimate, helping them retain moisture and stay cool.
3. Increase Humidity Levels
Air conditioning and summer heat can reduce indoor humidity, leading to crispy leaves and slower growth. Certain plants, like calatheas, ferns, and orchids, need extra moisture to stay healthy.
To increase humidity, mist your plants once or twice a day, place a tray of water with pebbles nearby, or use a humidifier in dry rooms. Grouping plants together also helps create a mini greenhouse effect, keeping the surrounding air moist and comfortable.
Avoid placing plants near air vents or fans, as direct airflow can dry them out faster.
4. Keep an Eye on Pests
Warm, dry weather encourages pests like spider mites, aphids, and whiteflies, which can damage your plants if left unchecked.
Check leaves, stems, and soil regularly for tiny bugs, webbing, or sticky residue. If you notice pests, wipe the leaves with a damp cloth, spray plants with neem oil, or use insecticidal soap to eliminate infestations naturally.
Keeping plants clean and well-hydrated makes them less susceptible to pests. Washing leaves gently with lukewarm water once a month helps remove dust and discourages insects from settling.
5. Repot Plants If Needed
Summer is an excellent time to repot houseplants that have outgrown their containers. Signs that a plant needs repotting include roots growing out of drainage holes, stunted growth, and soil drying out too quickly.
Choose a slightly larger pot with good drainage and use fresh potting mix to provide new nutrients. Water the plant well after repotting and keep it in a shaded spot for a few days to help it adjust.
6. Avoid Fertilizing Too Much
Plants grow actively in summer, but too much fertilizer can stress the roots and cause nutrient buildup. Use a diluted liquid fertilizer every 3-4 weeks to provide essential nutrients without overloading the soil.
If your plant is struggling with heat stress, skip fertilizing until it recovers. Over-fertilized plants may develop brown leaf tips or white crust on the soil surface, indicating excess salts.
7. Move Plants Outdoors (Carefully!)
Many houseplants enjoy summer fresh air but need time to adjust to outdoor conditions. If you decide to place plants outside, start by gradually exposing them to outdoor light for a few hours a day.
Keep them in shaded or partially sunny areas to prevent sunburn. Monitor for wind exposure, pests, and temperature changes to ensure they adapt smoothly.
8. Monitor for Signs of Stress
Summer stress can cause drooping, yellowing leaves, or curling edges. Watch for these signs and adjust care accordingly.
If your plant looks wilted by midday, it may need more water. If leaves start browning, move it to a cooler spot with filtered light. Regularly cleaning leaves and trimming dead foliage helps plants recover faster.
Keep Your Plants Happy This Summer
Summer brings challenges for houseplants, but with proper watering, humidity control, and sun protection, they can thrive. By making small seasonal adjustments, you can ensure your plants stay healthy, vibrant, and lush all summer long.
Happy Gardening! 🌿☀️

Yes, direct sunlight can cause scorched leaves. Move sensitive plants to indirect light or use a sheer curtain to diffuse sunlight.
Should I mist my plants in hot weather?
Yes! Misting helps increase humidity for tropical plants, but avoid over-misting succulents and cacti.
How can I prevent pests during summer?
Regularly check leaves for signs of bugs and wipe them with neem oil or insecticidal soap. Keeping plants clean and well-watered reduces pest risks.
Can I place my houseplants outside in summer?
Yes, but introduce them gradually. Start with shaded areas and monitor for sunburn or pests.
