Once summer passes, the succulents at home are practically going through a life-and-death ordeal. If they make it through, they turn beautiful in autumn; if not, they just die! So which succulents are most prone to black rot? Huahua is here today to run through them!

1. Echeveria 'Ruyu' (Echeveria glauca): the vanguard of death

Black rot death style: first the roots rot black, then it spreads rapidly to the top

At the mention of black rot, what many flower lovers think of first is definitely Echeveria 'Ruyu'! Although Echeveria 'Ruyu' is as beautiful as a flower, it is also the most prone to black rot; some don't even make it through summer before dying!

Solution: You can keep the side shoots and the head; the side shoots can be picked off for cuttings, and the head can be beheaded to regrow

Summer survival guide:

1. Place Echeveria 'Ruyu' indoors in a spot with good scattered light, do not expose it to harsh sun; water only when the leaves feel soft to the touch, and never water too much.

2. In summer, you can use a fan to blow on it to prevent the pot soil temperature from getting too high and suffocating the roots; ordinary garden soil is fine, there is no need to specially mix soil.

2. Echeveria derenbergii: certain death in summer!

Black rot death style: turning to mush and dropping leaves, black rot starting from the roots

On the succulent black rot rankings, the top three definitely include Echeveria derenbergii. When the leaves drop, you only then discover that the stem has already rotted black.

Solution: Remove the mushy leaves, behead the part that has not rotted black and let it re-root

Summer survival guide:

1. Ensure the pot soil is loose and breathable; you can choose perlite and coconut coir mixed at a 1;1 ratio, and before summer you can choose a red clay pot.

2. Pay attention to ventilation and shading; in summer you need to put up a layer of shade netting to avoid harsh sun, and watering about once every 7-10 days is enough.

3. Sedum clavatum: the black rot monster!

Black rot death style: black rot starts from the top; even if you behead it, in no more than 3 days the stem still goes soft

Solution: Cut off the black-rotted head, use the healthy leaves for cuttings, and just throw away all the black-rotted parts

Summer survival guide:

1. Place it indoors in a well-ventilated spot with good scattered light, and never expose it to direct harsh sun, otherwise the high temperature will scorch it to death immediately.

2. Ventilate often and water sparingly, avoiding the pot soil staying stuffy and hot for long periods, so that Sedum clavatum can get through summer safely.

4. Cotyledon tomentosa: dropping leaves!

Black rot death style: first the leaves drop, then the entire stem shrivels, and it slowly dies

Solution: If you notice leaves dropping, dig out the Cotyledon tomentosa; if the stem is intact, let it dry and repot it; if the stem has rotted black, then just behead it for cuttings

Summer survival guide:

1. Cotyledon tomentosa is especially afraid of heat; when summer temperatures are above 30°C, it enters dormancy, and at this time just keep it in a cool, ventilated place with scattered light.

2. In summer you must control water, watering once a month is enough; choose a windy, cool evening to water, no need to water thoroughly, just slightly moisten the roots.

5. Echeveria 'Romeo': rapid black rot!

Black rot death style: first the core rots, then the leaves drop, and it rots black rapidly

Solution: Dig out the plant, remove all the rotted leaf core and black-rotted leaves, trim the roots a bit, keep the healthy parts, let them dry and replant; if the black rot is especially severe, then you can only throw it away.

Summer survival guide:

1. Choose loose, breathable nutrient soil; you can mix a little sand or perlite into the soil to prevent the roots from being suffocated by summer stuffiness.

2. Summer weather is hot, so you can place it indoors with a fan to cool it down; when watering, just give a little water along the edge of the pot.

6. Echeveria 'Furong Xuelian' (Echeveria laui hybrid): hard to get through summer!

Black rot death style: the bottom leaves rot black and turn to mush, leaves drop, then the stem turns black

Solution: Pick off the black-rotted, mushy leaves, then behead it; if after beheading the stem is not black, then apply some carbendazim and replant, but if the stem is already black, then there is basically no saving it.

Summer survival guide:

1. More sun makes the color look better. Pay attention to shading at noon; in the early morning and evening, when the sun is not especially harsh, you can let it get direct sun so the Echeveria laui colors up, and the white powder on the leaves looks even better!

2. Water less; water only after you touch the pot soil and find it completely dry; water slowly along the edge of the pot, and do not spray water onto the leaves.

7. Sedum rubrotinctum: the leggy god!

Black rot death style: too much water and it immediately grows leggy and drops leaves; too little water and the stems go soft, leading to black rot

Solution: Cut off all the black-rotted parts, apply some carbendazim to the wounds, place in a cool, ventilated spot to let the wounds dry, then repot.

Summer survival guide:

1. Aside from needing a bit of shading at noon in summer, at other times direct sun is no problem at all.

2. Be sure to be careful with watering; you can choose to do it at night, and be careful not to get water on the leaves, to avoid direct sunlight scorching the leaves.

8. Echeveria 'Xiaohongyi' (Echeveria minima): certain death in summer!

Black rot death style: the bottom leaves turn to mush first, then the stem rots black and the whole plant dies

Solution: Remove the mushy, withered leaves, and also promptly cut off the black-rotted leaves; let the remaining wounds dry and then replant.

Summer survival guide:

1. Ventilate often. Once it is stuffy and not ventilated, Echeveria 'Xiaohongyi' can die in no time. You must ensure windows are opened every day for ventilation, or use a fan to cool down the Echeveria 'Xiaohongyi'.

2. Ensure the pot soil stays slightly dry; lift the pot to check the soil, and water a little only after it feels noticeably lighter, but do not water thoroughly.
