In the past few days, many regions have seen obvious temperature drops, and many friends can't wait to start planning their big autumn open-air growing plans!

But after browsing various succulent forums and websites, I found that aside from the surprises brought by open-air growing in some areas, there is more of this style~

Succulents that barely made it through summer ended up dying from sunburn in autumn~~

This lesson tells me that sun protection is still quite important, so I did a simple summary.

1、Avoid suddenly moving them from a position with weaker sunlight to strong light.

Tip: For example, suddenly moving them from indoors to outdoors, or suddenly removing the shade net on a sunny day. In this situation, light intensity and duration should be increased gradually,for example, move them out during several consecutive cloudy or rainy days, so the shaded succulents have a relatively buffered adaptation period.

2、Sunburn does not necessarily show on the plant leaves the same day; various scars may appear over the following week.

Tip: Observe more, pay more attention! Especially to short-term weather changes.

3、Those already sunburned need to be moved to a position with relatively weaker sunlight and wait for the plants to recover on their own. Maintain normal care and ventilation.

Tip: Ventilation and normal care are very important. But do not overprotect them; if the shading is too heavy, moving them out for open-air growing again may repeat the same mistake~

4、If you like open-air growing, even if sunburn appears, you do not have to move them. Keep the current environment, and the plants will slowly train themselves to adapt to this sunlight intensity.

In daily care, watering should be reduced somewhat to avoid rot caused by water evaporation. This method is not suitable for small seedlings, as there is a certain possibility of death by sunburn.

Tip: If you want to persist with open-air growing, do not be afraid that short-term sunburn will damage the succulents' appearance. The most beautiful is always after rebirth through fire!

5、The most dangerous thing is not strong sunlight, but water evaporation.

After watering, the moist soil receives strong sunlight and exposure, the inside of the flowerpot begins to heat up, and water begins to evaporate,creating a sauna effect. The plant's roots will be suffocated, and then the whole plant will rot.

So watering is best done at night or on cloudy days, and watering under a blazing sunny sky must be avoided. (Most summer rot is caused by this reason, which is also why areas with particularly high summer temperatures need to cut off water)

Tip: Still pay attention to watering! Always pay attention to local weather changes!

Another example: if Aeonium-type plants have not been trained by strong sunlight and are suddenly moved from a position with relatively weak sunlight to strong sunlight, the situation in the picture below will appear. Doesn't it feel like they haven't woken up...

In the first two days after sunburn, the leaves did not change much, butafter 3-5 days, scars on the leaves appeared one after another.

Note that the ones in the picture below are all sunburn, just milder.

Fortunately, Aeonium-type plants replace old and new leaves very quickly. After normal care, they can recover in about two weeks. The sunburned leaves slowly dry up and fall off, and then new leaves grow from the center.

So Aeonium arboreum 'Zwartkop' can also be grown open-air without problems. It may experience a period of sunburn, but once the plant fully adapts, there is nothing to fear.

But other varieties with thicker leaves are not so lucky. Their recovery speed is especially slow, basically starting at 3 months.

Especially for those whose central growth point has also been sunburned, manual excision may be needed to stimulate new buds again, otherwise they will never grow well.

Even among Crassulaceae, the degree of sunburn varies. Each variety and the health level of each plant will also be somewhat related to the degree of sunburn. If the lower leaves are sunburned as in the picture below, it does not matter; they can recover quickly.

In this situation, tweezers need to be used to remove the sun-dried leaves in the middle. The problem is not too serious.

Just slowly wait for recovery!If flower stalks emerge at this time, they can all be cut off, so the plant can preserve more nutrients to recover its body!

Everyone can observe more and see whether their own plants are also sunburned.

Although sunburn is somewhat easier to recover from than winter frostbite, there can still be deaths from sunburn, and most of those directly killed by sunburn are seedlings.

The appearance of rot and wateriness is not the legendary "black rot", but is caused by water evaporation + strong sunlight creating a sauna effect inside the flowerpot. For high-mountain plants such as Sempervivum, it is especially fatal.

In the end, one piece of advice: although autumn has arrived, succulents that have been grown indoors for a long time must not be rushed outside for open-air growing!
