Can a cold frame be used in summer? That's a question I get asked a lot as a cold frame supplier. You might think cold frames are just for winter, but let me tell you, they can be super useful in the summer too.
Understanding Cold Frames
First off, for those who aren't sure what a cold frame is, it's basically a simple, unheated greenhouse. It's usually made with a bottomless box and a transparent top, like glass or polycarbonate. The idea is to trap heat from the sun, creating a warmer environment inside than outside. This helps plants grow earlier in the spring and stay protected in the fall. But what about summer?
Benefits of Using a Cold Frame in Summer
1. Protection from Extreme Weather
Summer can bring some pretty crazy weather. We get those sudden downpours that can wash away young plants, and intense heatwaves that can fry them. A cold frame acts as a shield. The transparent top keeps the rain out while still letting in sunlight. And if it gets too hot, you can prop the top open to let out the excess heat and keep the air circulating.
2. Pest Control
Bugs and pests love summer as much as we do. They see our gardens as an all - you - can - eat buffet. A cold frame provides a physical barrier against many common garden pests like aphids, slugs, and caterpillars. You can even add some fine mesh to the openings to keep out smaller insects.
3. Extended Growing Season
Just because it's summer doesn't mean you can't start prepping for the fall. You can use the cold frame to start seeds for your fall garden. Lettuce, spinach, and kale are great candidates. Starting them in the cool environment of the cold frame in summer will give you a head start, and you'll have healthy plants ready to transplant when the weather starts to cool down.
How to Use a Cold Frame in Summer
Temperature Management
The key to using a cold frame in summer is keeping the temperature in check. On hot days, you need to open the top of the cold frame to release the hot air. You can use a simple prop or invest in an automatic vent opener. This will open and close the vents based on the temperature inside the frame. At night, if the temperature drops significantly, you can close it up to keep the plants warm.
Watering
Plants in a cold frame will need regular watering, especially in summer. The enclosed environment can cause the soil to dry out faster. But be careful not to over - water. You want the soil to be moist but not waterlogged. A good way to check is to stick your finger about an inch into the soil. If it feels dry, it's time to water.
Plant Selection
Not all plants are suitable for a summer cold frame. You want to choose plants that can tolerate the slightly warmer and more humid environment. Herbs like basil, thyme, and oregano do really well. You can also grow some varieties of tomatoes and peppers, as long as you keep an eye on the temperature.

Tips for a Successful Summer Cold Frame
Ventilation
Good ventilation is crucial. Make sure there are enough openings in the cold frame to allow fresh air to circulate. You can also use fans to improve air movement, especially on hot, still days.
Shade
Sometimes the sun can be too intense. You can use shade cloth to cover part of the cold frame. This will reduce the amount of direct sunlight and prevent the plants from getting sunburned.
Cleaning
Keep the cold frame clean. Remove any dead leaves or debris regularly. This will prevent the growth of mold and fungi, which can harm your plants.
