Succulents are among the most low-maintenance and resilient plants, but summer heat can still take a toll on them if you're not paying close attention. Whether you’re a new plant parent or a seasoned succulent lover, understanding their needs during the hottest months can make all the difference. The dry air and soaring temperatures of summer may mimic their natural desert habitats, but even the hardiest succulents can suffer from sunburn, dehydration, or root rot when conditions are extreme. Here are ten human-tested, plant-approved ways to help your succulents thrive all summer long.
1. Mind the Sun—But Don’t Overdo It
Succulents love sunlight, but too much direct sun, especially in peak afternoon hours, can scorch their leaves. If your succulents live outdoors, consider moving them to a spot where they can get morning sun and afternoon shade. Indoors, place them near a bright window but rotate them every few days so all sides receive light evenly. Watch out for signs of sunburn, bleached or brown patches on leaves, and adjust accordingly.
2. Don’t Overwater—Trust the Leaves
In the heat of summer, it’s tempting to water your plants more often, but resist the urge. Overwatering is the number one killer of succulents. Instead, feel the soil first. If it’s completely dry a couple of inches down, it’s time to water. Look at the leaves too, if they’re wrinkling or feeling soft, your plant is thirsty. On the other hand, mushy leaves usually mean too much water.
3. Use the “Soak and Dry” Method
When you do water, water deeply. The “soak and dry” method mimics the natural rainfall succulents are used to, drench the soil thoroughly and then allow it to dry out completely before watering again. This encourages roots to grow deep and strong and prevents rot, which is common during humid summers.
4. Choose the Right Pot
Terracotta or clay pots are best for summer because they allow soil to dry out faster than plastic or glazed ceramic pots. Good drainage is non-negotiable, so make sure your pot has holes at the bottom. Standing water is a big no-no for succulents.
5. Keep an Eye on Humidity
Most succulents are desert plants and dislike high humidity. If you live in a humid climate, make sure your plants are in a well-ventilated area. Indoors, a fan or open window can help. If you're using a humidity tray or misting your other houseplants, keep the succulents away from them.
6. Repot If Needed—But Carefully
Summer isn’t the ideal time to repot, as the heat can stress the plant. However, if your succulent is clearly outgrowing its pot or the soil isn’t draining well, it might be time. If you must repot, do it early in the morning or late in the evening when temperatures are lower, and allow the plant to rest in the shade for a few days afterward.

Protect from Pests
Warmer months invite uninvited guests like aphids, mealybugs, and spider mites. Check under the leaves and at the base of the plant regularly. If you see cottony clumps or sticky residue, act fast. Use neem oil or an insecticidal soap spray, and isolate the affected plant to avoid spreading pests to your other succulents.
-
Fertilize Lightly
Summer is a growing season for many succulents, so a little feeding can help. But don’t overdo it. Use a diluted, balanced, water-soluble fertilizer once a month at most. Too much fertilizer can burn the roots and damage the plant. Always water first before applying fertilizer.
-
Don’t Crowd Them
Succulents need airflow around their leaves to stay healthy. If you have a big collection, make sure each plant has a bit of personal space. Grouping them too tightly can trap humidity and limit ventilation, leading to rot or fungal issues.

Give Them a Summer Break!
Just like people, succulents sometimes go dormant during extreme heat, especially varieties like echeverias and haworthias. During dormancy, growth slows down, and the plant may look a little dull. Don’t panic, this is normal. Cut back on watering and let them rest. When the temperatures dip, you’ll see them perk back up.
Keeping your succulents healthy in summer doesn’t have to be complicated. With a little attention and some basic care, these hardy little plants can survive—and even thrive—during the hottest months of the year. They may not be able to ask for what they need in words, but once you start paying attention, they’ll show you in their own quiet, leaf-whispering way. So grab your watering can (sparingly!), give them a little shade, and enjoy the green company all summer long.
