Brown Spots On Succulents | Reasons And Prevention Methods |

Succulents usually grow in their natural habitats all over the world. Further you could spot many people have grown them indoors as attractive home-grown plants as well. These succulents have a natural  defense system to conserve water during intense heated times. They usually retain water in the plant. Those water retaining parts are prone to get infestations  and get diseases . Further they will get disorders which will lead to discolor of the plant along with brown spots.

When we proceed with this further, it is important to note on few factors which cause the brown spots on the succulents.  There are three main factors for this such as Succulent Edema , dissolved salts and chemicals and fungal diseases.

Causes for brown spot in succulents

Succulent Edema

First one would be Succulent Edema. It is a well known fact that their leaves are thick, fleshy and water retaining. However you should not water them intensively based on those facts. Instead you need to water them on a moderate level when it is necessary only. You should  do it ideally once the soil is dry enough. 

You could spot the succulents best growth when their soil gets dry between watering. If you  keep the succulents plants in too much moisture and if you  leave them in waterlogged soil for longer periods,  they will start to struggle with Edema. 

This  will eventually cause the plant to have brown, corky patches on the leaves. Chances are that those spots could come up in the undersides of the leaves which will make it more complicated to identify the disorder. Brown spots would be visible significantly on the white areas of the variegated succulents.

Dissolves salt and chemicals

Dissolves salt and chemicals is  the second factor which could cause the brown spots on succulents. Unlike other plants in general succulents, they  would not prefer too much fertilizing for them. You should apply fertilizers as appropriate  if necessary and  through  dilute fertilizer applications. 

If a succulent is getting fertilizers more,  the salt in the fertilizer will lead for root burns.. Ultimately the leaves will also burn and get brown spots.  In fact  chances are that  the salty soil system could move upwards well.

Fungus diseases.

Third factor for brown spots on succulents would be fungus diseases. Succulents are prone to get fungal leaf spot diseases. Pathogenic fungi require water for their sexual reproduction to spread out. These diseases spread rapidly in moist areas and in foggy climates.

Once the fungus  dominates and takes over the control of the plant, it will form brown spots on the surfaces of the leaves which will ultimately cause large lesions. Unfortunately there are no  treatment once your succulent gets this disease and that will lead the plant to deteriorate

Is Brown spots bad for succulents?

It could be bad for certain succulents only. Although the brown spotted plants do not look aesthetically nice ,  they are not really  harmful for certain plants.  On the other hand, there could be certain succulents which could get harmed  from the brown spots.   However the brown spots due to the sunburn will remain on the leaves and they will not fade away.

Brown spots on succulent plant leaves

Sunburn and intense heat conditions are two main factors which will cause brown spots on leaves.  In case you have changed the location of the succulent to a bright sunny location where it get too much heat and too much sun rise and if it has got brown spots on the leaves these spots are sun burns

Brown spots on succulent stem

if your succulent stem contains brown spots,  it tries to show that the succulent is struggling and it is rotting. Absorbing too much water is the main cause for rotting and if you spot any blackening over the stem, best would be to cut it off until the stem looks healthy  Eventually a tiny baby succulent could emerge at the base of the stem.

How to fix brown spots on succulents.

First, you should minimize watering  and you should take  necessary steps to supply more sunlight for the plant. You should do watering only after the soil is dry again. In case, you have grown the plant in an inappropriate soil type,you should take off  the plant and let it dry for about two days.

Then ultimately you should plant it in a more appropriate , well-draining potting mix. It is  important to note that it’s always better to prevent the plants getting brown spots. As always  prevention is always better than cure.

Preventing the plants from getting brown spots is a very simple process.  Best would be to use a porous, well-draining soil. If you are making it on your own, you should  use 60 percent peat moss to 40 percent perlite or equal parts potting mix and coarse sand. 

If you have  grown them  in pots or in containers indoors we should ensure that we select the ones which have a good drainage system. Simultaneously, we should continue watering the plants until the additional water exists which will in return flush excess salt.

Why does my succulent have dark spots?

You could see Succulents having  black spots and  that mainly happen due to water warts, fungus and rot.Succulents are easy to care for plants in general. However chances are that they could also get pests attacks  and diseases. succulents in general don’t like moisture and hence why they get badly affected from water warts, fungus and rot these  despite how hardy they are. 

Second is the sunburn. Exposing them for scorching sun for prolonged periods is not healthy for  them. Pests such as aphids, mealybugs, could also cause for the succulents to have dark spots. Frost and overwatering are two more reasons for the succulents to have dark spots.

How do you get rid of dark spots on plants?

Keep the plants under constant observation  

Constant inspections could  help in identifying these issues in advance so that we could overcome that.  Spend a few minutes of your day  and observe  whether your plant is showing physical changes 

Isolation and repotting

 If you come across any new plant make sure that it stays separate from others so that you can see if it has any diseases already. By quarantine you can protect the other plants from that. Same thing applies for repotting as well since if there are any root rot you could spot it at once.

Ensure Hygiene

Maintaining hygiene of your garden is equally important. If your area has all sorts of dead plant material and if it is wet, fungi will love that as  that is the perfect breeding place for them.

Leaves Can Turn Brown from Underwatering

 Underwatering is one more reason for the leaves to  turn brown. On top of that, if there is  too much heat , sun rise , the plant will have a shriveled appearance along with burned leaves too. Nevertheless, it is not that hard to fix an under watered plant.

Generally , the plant will bounce back rapidly as soon as we fulfill  their water requirement . It is relatively easier to fix an under watered plant rather than fixing an overwatered plant.

Best Watering Tips for succulents

The ideal recommendation to water the succulents would be to use the Soak and Dry method. It is very simple as you have to first soak the soil with water entirely. After that  let them dry totally, before we start on the next watering session. In the meantime, we should ensure that they get the best draining soil type with good ventilation.

What cause rust on succulents?

Fungal parasites which require live plants for their survival is the main reason for rust disease. You could spot this disease mostly in mild, moist conditions. Transferred spores from infected plants  to the healthy pants  spread the rust.
