Why and how succulents get sunburn? 

Why & how succulents get sunburn?

Succulents are tough plants and can handle the harsh sun rays much better than regular plants; maybe the reason behind it is their desert and semi-desert origin. Some indoor succulents from tropical areas are habitual to a humid environment and don’t need too much sun. Also, succulents from desert origin grow under rocks or large trees, saving them from the afternoon sun. But, there is a limit to how much they can tolerate, and when it exceeds, you can start seeing the ill-effects of it. In total, we can say that sunburn is caused by a sudden increase in sunlight exposure for a succulent and therefore it mostly happens in summers, when the sun’s heat is its peak.

How can one tell the succulent sunburn situation? How bad can it get?

How to tell Succulent sun Burn

Their leaves tell all the story when it happens to them and that is the sign for a gardener to take care of them and bring them out of this disastrous situation. Because if neglected, this situation can worsen more and can lead to its death too. And, seriously, no one would like to see their lovelies die slowly in front of their eyes.

Signs of sunburn start to appear on the leaves first, starting with brown spots on them, and with the time when the situation becomes worse, it starts to spread to from the edge’s side. The topmost layer of the leaf burns first, resulting in discoloration of it to brown.

Sunburned top layer results in a break of the photosynthesis process, which hurts the food intake, and results in a lack of nutrition and de-growth.

After more exposure, water cells under the layer start to dry up; this leads to the shrinking of leaves. Later they attain that crispy texture; it may exceed so much that, if one touches it, they can hear the crackling noise. Severe sunburns are lethal for a succulent and can result in permanent damage or complete obliteration of it.

Can succulents recover from sunburn damage? Can they be revived?

Is it possible to comeback from succulent sunburn?

Brown spots spread across the leaf are one of the major early signs of sunburn. However, this situation is not critical and is reversible, but it is possible only if succulents are taken to the shaded area as soon as possible.

A delay may pave the path for a much grave situation, where the top layer of the leaf starts deteriorating, changing its color to brown. And its texture also varies to dry and crispy, and if the situation worsens, they may crumble on gentle touch.

Coming back from the severe sunburn is mostly not possible, and propagation from a remaining healthy part of a new plant is the only option left.

However, reclaiming early-stage sunburned succulents is not straightforward sometimes. You have to acclimate it to the shady areas also, by reducing the sunlight slowly. This way, they do not get the sudden jolt of atmosphere change.

You can expose them to morning sunlight only, but, moving them away from the direct heat of the afternoon. And soon, they will get accustomed to the newer surroundings, and the new growth will replace the brown spot leaves.

Does climate/weather play a role in increasing or decreasing succulent sunburn chances?

Yes, weather and surroundings do affect the chances of sunburn. Regions that belong to arid areas and have an abundance of sunlight are more prone to sunburn. Hot winds in the drier regions suck out the water from the succulent leaves sooner, making them more vulnerable to sunburn. On the other hand, humid and less sunlight receiving area reduces the chances of sunburn.

Why some varieties are safe from succulent sunburn & some are not?

It is quite a confusing topic for most succulent lovers, why some succulents in their garden get the sunburn easily, while some stand upright with glory even in the harsh afternoon rays. It depends on some factors that decide the capability of a succulent to withstand the sun’s brightness.

Types of Succulents

They are not able to handle the excess sunlight and may start showing the symptoms of sunburn. Some plants are tougher in outdoor garden varieties than others, making them sturdy enough to control the extra sun glare better.

Succulent Size

Succulents that are tall and wide receive more sunlight than their shorter counterparts. As they serve as the roof of the succulent garden and shorter ones stay under their shade. Putting small, vulnerable ones under larger ones saves them from direct sunlight most of the time, but some sunlight and dry winds sometimes damage them. Although tall ones are tough, care is essential as excess sunlight in summers may hurt their leaves.

Succulent placement & location

Succulent placement in your garden is also quite decisive for the sunburn issue, as placement of your succulent decides how much sunlight it will get and for which time of the day.

One can use trees to provide shade from the afternoon sun or opt for artificial methods like an umbrella or a construction.
