Summer sun is out and so are your succulents… But are they getting an unhealthy amount of summer rays?
Succulents - the plants known to thrive in sunny southern California and Mediterranean climate regions world-wide - can actually become damaged from an excess of solar rays.
Today you’ll find out how much light is optimal for your specific collection of succulents, and learn how to spot signs of light stress and overheating. Then we’ll explore ways to keep your succulents safe from over-exposure, and thriving all summer long.
Low-Light vs. Full-Sun Varieties
Some species of succulent are more sun-loving than others. Varieties with spines, spikes, and blue and gray hues are more tolerant of direct sunlight and high heat. Think cacti and agaves – natives to North America’s hot dry desert region.
Sun-loving succulent varieties include:
It is important to be mindful of the specific varieties of succulents in your collection, so that you can properly accommodate their needs.
Light and Heat Stress
So what’s the worst that can happen when a succulent is left outside in a high-heat, high-light environment?
Just like people, succulents can get sunburned. When exposed to light beyond optimal levels, sunburned succulents will develop brown spots, wrinkled leaves, and dry, crispy edges. In severe cases sunburn will result in necrosis: leaf tissue will turn black, die, and fall off.
Heat stress can cause problems as well. When plants overheat due to hot soil temperatures, their roots will be damaged, negatively affecting their root’s ability to nourish the plant. Plants in dark colored plastic pots are more susceptible to heat stress than those in ceramic pots or in the ground.
Is light stress always bad?
Before you rush to shade all your succulents, note that some people choose to induce light stress for their succulents.
Mild light stress can cause a spectacular change in color, as the plants shift their pigment production in order to better protect themselves from the sun’s rays. Many varieties, like these echeverias, will take on a vibrant reddish-orange hue.
It is important to be aware of your particular plant’s light needs, and to proceed slowly if you choose to induce light stress.
