Help what should i do? i think i overwatered my haworthia, leave are squishy and turning to brown. #succulents #haworthia
@ElderFicusruby hi and welcome to Greg. This is a common plant disease that results from excess moisture in the substrate. In a separate post I will share my notes on treatment. These plants are from arid regions; that you have root rot evidences that the substrate is suitable for the plant. These plants need a substrate that is well draining and retains less moisture. Once you have treated the plant per the details that follow, you will want to make a suitable substrate. You can take an indoor potting mix and add perlite, which is a volcanic rock in a ratio of 1 part potting mix to 1 part perlite. Then you can water per Greg recommendations.
@ElderFicusruby root rot info: Assessment: Carefully remove the plant from its pot and examine the roots. Healthy roots are firm and white, while affected ones are mushy, brown, or black.
* pruning: sterilize scissors with rubbing alcohol to prevent spread of contagion, trim away all diseased, mushy roots using sterilized scissors. Cut until you reach healthy tissue, ensuring there are no remaining affected parts.
* Leaf pruning: Trim any yellow or diseased leaves as well, as they can't recover and might exacerbate the issue..
* Peroxide Treatment: Use a weak hydrogen peroxide solution (1 part 3% hydrogen peroxide to 3 parts water) to soak the remaining healthy roots. This helps in disinfecting and stimulating root growth.
* Replanting: Choose a clean pot with proper drainage. Fill it with a well-draining potting mix. Plant the Chinese evergreen, ensuring the healthy roots are well-covered but not buried too deeply.
* Care after Replanting: Provide appropriate watering, ensuring the soil is moist but not waterlogged. Place the plant in suitable light conditions, avoiding direct sunlight.
Remember, aftercare is critical. Monitor the plant closely for signs of recovery and adjust care routines as needed.

Here is more background info on root rot:

root rot is a condition where the roots of a plant are damaged due to an overabundance of moisture or poor soil conditions. It's often caused by the proliferation of specific fungi, such as Pythium, Fusarium, or Phytophthora, which thrive in excessively wet environments. These fungi attack the roots, impairing their ability to absorb water and nutrients, leading to the deterioration of the root system.
The causes of root rot:
* Saturated soil conditions: Excessive moisture in the soil prevents proper aeration, suffocating the roots and creating an environment favorable for fungal growth.
* poor drainage: soil that retains water for extended periods can promote the development of root rot.
* Pathogenic fungi: Certain fungi exist naturally in soil but become problematic when conditions become overly damp, allowing them to attack the plant's root system.
Prevention strategies for root rot:
* soil Amendments: Incorporate well-draining materials like perlite, sand, or organic matter to improve soil structure and enhance drainage.
* Proper Potting Medium: Use a high-quality potting mix specific to the plant's needs, ensuring it promotes good aeration and drainage.
* Appropriate Watering Practices: Allow the soil to partially dry between waterings to avoid consistently soggy conditions. Water plants according to their specific needs, avoiding both under and overwatering.
* Container Selection: Use pots with drainage holes to facilitate excess water removal.
* Plant Health Maintenance: Ensure overall plant health by avoiding overcrowding, maintaining appropriate plant spacing, and removing any dead or decaying plant material which can serve as a breeding ground for fungi.
Implementing these preventative measures helps create an environment less conducive to the growth and proliferation of the fungi responsible for root rot, thus safeguarding the plant's root system and overall health.
Thank you so much for sharing your notes or knowledge about taking care of these plants
The only change I would change in @TexanExpat’s fabulous instructions is to not follow the Greg watering prompts blindly. Don’t let it substitute for your own observation. It is best practice to check your plant’s soil before watering to be sure it’s as dry as it should be according to your plant type. Greg is pretty accurate, but it can’t know the unique conditions in your home. There are all sorts of variables like humidity, indoor temperature, pot shape, etc. All of these affect the plant’s watering needs.

Greg can learn, however. Check the dirt often and if you find it dry enough, water it and hit water in the oasis. If Greg tells you to water and the soil is still too wet, hit snooze and wait a couple of days. Over time, Greg will adjust its recommendation according to your input and make it more and more accurate.

Do you bottom water? It is highly advisable. Place your plants (pots only, no saucers) in a tray of water that comes up an inch or so on the side of the pots. Leave them to soak for 20 minutes or more. Then, set them aside to thoroughly drain before returning them to their saucers. If after 5 minutes there is water in any of the saucers it is very impotant to pour it out. This method guarantees your plant will be thoroughly watered while the top will remain dry. This discourages bugs, especially the great scourge, the notoriously evil, fungus gnats.

Sending happy plant thoughts! ❤️
@TruthfulApricot I agree with you re not watering without checking. In fact, the mechanics of the algorithm rely on the user to provide the final datapoint—whether the conditions in the substrate are ripe for a watering—in order to refine itself and provide accurate guidance. We don’t really think of the “snooze” button performing such an important task but it does. As to bottom watering, I do this sometimes with my plants but for succulents, I expect it is less optimal. The roots for these plants are equipped to grab whatever moisture they can as it passes through often rocky soil conditions that do not retain moisture. For this reason I think the “soak and dry” method is so often advocated for succulents. Do you find bottom watering is better for yours ?
Try repotting it in fresh soil, soil that’s made for succulents and cacti and drains well, and then don’t water it until a few days AFTER you usually would.
