Why Is My Cactus Turning Brown And Soft

Cactus tip rot, which is evident when the top of the plant begins to become dark and mushy, is most likely the cause (aka cactus stem rot).

That basically signifies that your cactus is starting to rot. If nothing is done, cactus stem rot will quickly become a serious problem.

A cactus will continue to deteriorate from the top down once it begins. The plant will finally perish as it continues to spread down the entire stem.

Therefore, it’s critical to take quick action as soon as you see cactus tip rot in order to save the plant.

How can brown cactus be fixed?

Look to check if the brown spot and the vicinity are mushy and soft. If so, your cactus has probably started to rot from the inside out and is now displaying symptoms on the outside.

After noticing soft brown areas, the best technique to fix your cactus is to cut off healthy stems (without any signs of rot) and start a new plant.

Before cutting, disinfect a razor blade or a pair of extremely sharp sheers. Cut the cactus above the area of rot, allow it to dry, callus over, and then plant it again.

Use fresh soil, and thoroughly clean and dry the pot if you’re using the same one. Unfortunately, there isn’t much you can do to save your cactus as is once it has begun to decay.

In other words, the only method to revive a cactus that has developed rot is to cut off the healthy stems—those portions of the plant that are still green—and repot them in fresh soil.

Why does my cactus keep tumbling over?

Stop watering it first, that is what you need to do. Prior to watering it once more, allow the soil’s surface to dry out.

Additionally, you might want to wait a week or two after ceasing watering before beginning again.

Placing your cactus in an area where it will receive more sun can also help it dry out more quickly.

The plant will evaporate the water more quickly with the aid of sunlight. The cactus can also be placed in an area with good airflow, such as close to a window or door.

It can take some time for your cactus to recover if you have been watering it excessively.

Keep your cactus well watered and patient, and you’ll soon witness it getting back to health.

Root Rot

Your cactus may get root rot if it has been submerged in water for an extended period of time or if the soil is very moist.

The plant will finally succumb to this and become floppy and squishy.

The cactus’s roots will begin to decay when the fungus assaults them, and the plant won’t be able to absorb water or nutrition. The cactus will eventually lose strength and perish as a result of this.

How to Fix It

Take your cactus out of the pot and cut out all of the rotten roots if you suspect it has root rot.

Take great care not to mutilate the sound roots. The cactus can then be replanted in a new pot with fresh dirt.

Keep an eye on it and remove any additional damaged sections because the rot can spread to the remainder of the plant.

It’s critical to clean the scissors or knife you used after removing the rot.

To do this, submerge them in a bleach and water solution. This will lessen the likelihood of the rot spreading to further plants.

Your dying cactus won’t be able to survive, though, if too much of the root system has decayed.

Poor Drainage

The soil of your cactus will grow damp and squishy if it is in a pot with poor drainage. The cactus will become pliable and its roots will decay as a result.

A pot that is excessively small or devoid of drainage holes for the plant may frequently result in poor drainage.

The soil will get damp and squishy because the pot will fill with water and prevent adequate drainage.

Additionally, employing a potting mix that prevents water from draining effectively can contribute to this.

The cactus will turn squishy if the soil is too dense or clumpy as it won’t enable the water to drain.

To ensure that the water can drain effectively, choose potting soil that is light and airy. For this, cactus soil mixture is ideal.

If the pot is too tiny, you can also create a drainage layer by packing rocks or gravel into the bottom of the pot.

Less watering is required if your cactus is in a pot with poor drainage. Prior to watering it once more, allow the soil’s surface to dry out.

Instead of watering the cactus from the bottom, you can also water it from the top. This will assist in draining any extra water that may be present in the pot.

Additionally, you must relocate it to a location with more sun. The plant will evaporate the water more quickly with the aid of sunlight.

Humidity

Because they are not accustomed to extreme humidity, cacti can grow limp and floppy.

They require a dry environment in order to thrive, and a high humidity level can harm them.

The cactus may get fungal illnesses due to high humidity, which will make the plant floppy and squishy.

You should relocate your cactus to an area with lower humidity if it is currently in a humid climate.

You should water your cactus less frequently if it is in a humid area. Prior to watering it once more, allow the soil’s surface to dry out.

Instead of watering the cactus from the bottom, you can also water it from the top.

However, be careful not to lay it directly in the sun as this could harm the cactus.

Fungal and Bacterial Diseases

Your cactus may have a fungal illness or bacterial disease if it is spongy and has dark soft areas.

The fungus or bacteria that generate black spots on cactus plants will eventually kill the plant by spreading to other sections of the cactus.

Cactus fungus may develop as a result of excessive irrigation, high humidity, or inadequate air circulation. A dirty pot, contaminated soil, or the use of unclean water can all result in the growth of bacteria.

You must use a fungicide or bactericide to treat your cactus if it has a fungal or bacterial condition. Another option is to use an organic fungicide, such neem oil.

You must get rid of any dead or rotting plant components if your cactus has a fungal or bacterial problem. This will aid in halting the spread of the infection.

The dirt and pot need to be cleaned as well. After boiling the soil for 15 minutes to disinfect it, wash the pot with hot water with soap.

By keeping the plant’s container and soil clean, providing it with the proper amount of water, and relocating it to an area with more sunlight and lower humidity, you can try to avoid fungus and bacteria from infecting your cactus.

By following these instructions, you can keep your cactus healthy and stop it from wilting.

Untreated Injuries

Your cactus may have been hurt if it is soft and lacks any black patches.

Falling off the pot, being struck by a hard object, or taking too much sun can all result in injuries.

Insect pests like mealybugs or scale insects can also harm cacti.

Without medical attention, wounds may spread an infection, which will cause the cactus to decay.

Additionally, wounds can make the cactus weak and prevent it from absorbing soil nutrients and water.

If it is infected, you can treat it with a fungicide or bactericide. Another option is to use an organic fungicide, such neem oil.

The injury might only need to be cleaned with mild soap and water if it is not infected.

To remove the damaged portion of the plant, you can use a sharp knife or pair of scissors. Before using the knife or scissors again, make careful to clean them.

Additionally, you must relocate it to an area with higher sun exposure and lower humidity.

The plant will evaporate the water more quickly with the aid of sunlight. However, be careful not to lay it directly in the sun as this could harm the cactus.

Insect Damage

A cactus may also grow soft due to insects like mealybugs or scale insects.

These bugs produce honeydew, a sticky substance that they exude after feeding on the plant’s sap.

Ants and other insects will be drawn to this substance, further harming the plant.

The cactus may weaken as a result of a pest infestation since it won’t be able to take up water or nutrients from the soil.

You have a choice between using a chemical pesticide or an organic pesticide like neem oil.

When using a chemical pesticide, be sure to take precautions and adhere to the label’s instructions.

The insects can also possibly be eliminated manually. Use a Q-tip dipped in rubbing alcohol to get rid of the pests if you have a little cactus.

It will be more challenging to manually remove the insects off a huge cactus. Either use an insecticide soap spray or try blasting them off the plant with a hose.

You must properly care for your cactus after the insects are gone in order to aid in its recovery. Trim away any cactus plant parts that are broken or dead.

When necessary, water the cactus and offer well-draining soil. To aid in the cactus’ recovery, you can also fertilize it.

If a pest infestation was the root of the issue, you must keep an eye out for new infestations on the plant.

Can you revive a dead brown cactus?

Overwatering is the cause of cactus rot. The cactus doesn’t require as much maintenance, despite owners’ perceptions that plants should be cared for frequently. The majority of cacti that unintentionally overwater and finally die are brown and black in color.

LET THEM GET DRY

The cactus is a plant that has to dry out as part of its life cycle, unlike most plants that become ill if they aren’t irrigated frequently. Cactus roots naturally receive very little water, therefore if you give them the same amount of water as you give your tomatoes, they will rot.

WATCH FOR MUSHY SECTIONS & DISCOLORATION

It’s crucial to keep an eye out for signs that your cactus is becoming mushy or is beginning to turn brown or black. These indicate overwatering has taken place. Most likely, the roots have already decayed and died. Simply put, avoid overwatering. Keep an eye on the soil around your cactus plants, and only water when the soil is absolutely dry. Although it may seem careless, the cactus is accustomed to that atmosphere in its natural habitat.

WHAT TO DO IF YOU’VE FOUND CACTUS ROT

It’s time to use a sharp knife to clip them off and repot or replant your cactus. Make sure to combine garden soil (2 parts), coarse sand (2 parts), and peat soil (3 parts) well (1 part). Additionally, make sure the pot you purchase has sufficient drainage holes and is somewhat larger. If you’re growing cacti outside, make sure the soil is well-draining and contains enough sand to aid this effect.

What does a cactus that is overwatered look like?

The obvious indicators of an overwatered cactus caused by a fungus in the soil include black or brown blotches and mushy stems. It’s time to carefully chop them off with a knife if you experience any of these bodily symptoms. Use a sterilized knife while handling a rotting plant to prevent the spread of the infection.

You will have to exert more effort if the damage is severe. Essentially, what you’ll be doing is multiplying the portions of your plant that are still alive. Wear nitrile gloves to protect your hands from the cactus’ spines while you chop off the rotting sections, and exercise extreme caution when handling the plant. After cutting out the damaged areas, let your cuttings air dry for a few days, or around a week.

How can you spot a dying cactus?

When a cactus looks shriveled and husk-like, it is dead. Additionally, dead cacti can become unstable in their soil and topple over. They could start to smell rancid and becoming mushy, both of which are indicators that they are rotting. Cacti that are dead lose their spines and frequently appear brown.
