Sansevieria, also known as snake plant or mother-in-law’s tongue, is a pretty popular succulent type. The reason behind it is their hardiness to go through adverse situations and fewer demands. And they are available in different varieties that can beautify your garden aura to the next level. Some people like the sansevieria of stiff-leaf types while some fall for the soft leaf ones, but everyone can have the darling of their choice.
The infestation of pests and mites is pretty common to the succulents, although one will wonder how their sansevieria got the mites. As they have not taken them outside, nor have given them the extra moisture or extra fertilizer. But the thing is, even if you have left a window open, mites ac haunt your indoor beauties. As we go to the outside environment, we are also the carrier of the mites, which can transfer to succulents later and play havoc.
Along with the problems like mealybugs, red spider mites, and gnats, soft leaf sansevieria faces another common rust rot. It might sometimes happen that a gardener sees red spots where leaves join with each other, but when they disturb it or scratch it, they will be surprised with the movement in these spots; they are red mites. Sometimes, there are some red rusty powder and spots on the leaf joints that start to spread slowly to other parts, especially eating the roots.
What causes rust rot in sansevieria?
Basically, it is a fungus problem due to over humid circumstances because of over-watering and bug infestation. Bugs prepare the circumstances that are suitable for the initiation of this problem.
They make the succulent moist and vulnerable; as they leave honeydew behind themselves also, they invite other insects like ants, which further make it susceptible to rust rot.
Soft leaf sansevieria is more attractive for mealybugs, red mites, and some other bugs as their parts are easy to ingest. And these bugs make the plant more vulnerable to fungus infection as either over-watering or over-fertilization was done because some bugs appeared, or it will be done to remove some bugs.
It might happen because of underwatering also, as some of the bugs appear in drier conditions, and what havoc they do later is known to everyone.
How can we identify it?
The leaf grouping part of the sansevieria starts to rot in over-humid conditions; red marks can be seen on the place where the leaves conjoin, i.e., the roots. It will feel like they are rusting; it is a fungal condition that can badly haunt succulent’s existence. One can have the powdery like feel while touching it and see that the roots are slowly succumbing to it.
The root will start to ferment and turn mushy as the rot increases, becoming incapable of providing succulent needs. Joint of leaves and root where you can see the red spots will start to spread, and soon the joints will loosen up, putting harm to the whole structure. It is a very deadly infection for the sansevieria as it can destroy it whole if it is not controlled in time.
How to solve this problem?
This lethal problem for succulents can only be solved if we focus on eliminating the root cause behind this problem. And that is the bug infestation that upsets the whole growth cycle of the succulent and produces the circumstances that make way for fungal problems like rust rot.
Eradication of bugs is the first step to solve this problem, and that can be done by spraying a solution of insecticidal soap on the affected parts where the bug or mite population is still present. When one is satisfied that he has covered all the affected areas, he can continue with the second step of fungicide spray to reduce the rot problem to a significant extent. Again, the spray of insecticidal soap should be repeated to eradicate the remaining pests.
This procedure needs to be repeated for two weeks at least for better effectiveness. Care needs to be taken that water is not provided to the succulent in this period; just try to destroy the infestation. Because watering can be some relief for the pests at that time, that can spoil your efforts to eliminate them.
Stages of the rust rot devastation that we may expect after infestation treatment:
- If you realized this rust rot problem really quick, very much in its preliminary stage, you are pretty lucky that you have the best chances of having back your succulent. So, the rot is limited to the center part of the plant, and some leaves also may have come up with some red spots or infestation signs. It is better to cut off that part of the leaves to prevent further spread, along with the proper following of the infestation and fungus control method discussed above, along with the precautionary steps. This is the best outcome that a succulent lover will think of, as he will be able to save his efforts, time, and most importantly, the beauties of his garden. But, that requires quick action to solve and curb the problem, and you might be rewarded with a happy mother plant.
- The second outcome that may come to our sights, if we identified the problem bit later and worked on its solution as described earlier. But after the treatment, the center part of the succulent is gone, but to our luck, most of the leaves are intact. That means we can still hope of having new growth, as the healthy leaves will make sure that we do not have to see our plant dying.
- The next outcome of this fungal situation is that when the center portion is exhausted entirely, and the leaves, rhizomes beneath the soil are still okay. This means our mother plant will be dead, but the good news is you can still have new offsets from the rhizomes. Rhizomes are the tube-like stems that connect all the leaves together, and they are responsible for producing offsets. And therefore, you will be able to have new small sansevieria in the same potting soil. You will have to make sure the infestation in your mother plant does not carry to the new ones.
- This outcome horrifies the gardeners, as it is the sign of complete devastation of your mother succulent. Leaves are gone completely, the center is also gone, and the only thing you are left with is the rhizome that you can dig out of the soil. And if it is still hard, that means it has not rotten or fermented, or we can say it does not smell and feels like one. You can re-pot it in another soil base then, obviously after the infestation treatment. And there is a possibility that with proper care, you may have a succulent from it, but that will take a lot of time.
- It is the worst situation of all; your all efforts have gone to vain now. Leaves are dead, so is the center, and now the rhizome that you had pulled out from soil also seems to be mushy and fermented. The only option you are left with is to have a brand new sansevieria for your garden. And be prepared to save it from the infestation.
