1. Adjust Your Watering Routine
As the weather warms, your plants need more water, but avoid overwatering. Instead of following a strict schedule, check the soil moisture regularly.
Poke your finger about an inch into the soil — if it feels dry, it’s time to water. Just keep in mind that some plants thrive in humidity, so excessive watering can cause their roots to rot. A little attention goes a long way in keeping your plants happy and thriving.
2. Pay Attention to Light Exposure
More sunlight doesn’t always guarantee your plants will thrive. While succulents love basking in direct sunlight to energize their thick leaves, shade-loving plants prefer gentler, indirect light to prevent leaf scorch and stress.
During hot summer months, move sensitive plants to areas with less intense rays or hang sheer curtains to diffuse sunlight, protecting them from harsh exposure. Small plant rearrangements can greatly improve their health, prevent sunburn, and help them flourish.
3. Maintain Humidity Levels
Even during hot summer months, indoor spaces can become surprisingly dry, leaving your plants parched. To help them thrive, try misting them, placing water bowls nearby to evaporate moisture, or grouping plants together for a humid microclimate.
A simple trick is to set a pebble tray filled with water under your pots; as it evaporates, it boosts the humidity around your plants. I have even been known to pop my plants into the shower to give them a cool gentle rainfall of their own.
4. Keep the Air Circulating
Ensuring proper air circulation is essential to prevent mold growth and keep pests at bay. On cooler days, open your windows to let fresh air flow through, and you can also use a small fan to keep the air moving indoors.
This is especially important if you grow humidity-loving plants, as stagnant air can lead to mildew and other problems for your plants. Good ventilation helps maintain a healthier environment for both your home and your plants.
Another tip is to clean your plant’s leaves with a soft cloth. Dust and dirt on their leaves can block sunlight, moisture, and air.
5. Protect Plants from Heat Stress
Extreme indoor temperatures can cause drooping, yellowing, or even sunburn-like symptoms on leaves. Make sure you monitor the temperature inside your home and try to avoid placing plants near heat sources like windowsills or kitchen appliances.
Want to save on energy bills? Keep your home cool without AC by closing blinds during the hottest parts of the day or using portable fans to circulate cooler air.
6. Fertilize Wisely
Your plants typically flourish in the summer, making it an ideal time to fertilize them. However, avoid over-fertilizing, as excess nutrients can damage your plants.
A good rule of thumb is to use a balanced liquid fertilizer every two to four weeks, but always dilute it to half the recommended strength. This way, you’ll encourage steady, healthy growth without risking overwhelm.
Before you know it, you’ll be passing summer with lush, vibrant plants decorating every corner of your home.
