Causes of Peace Lily Root Rot

Every plant parent knows that even the most aesthetically pleasing houseplants can be vulnerable to pesky issues like root rot. Peace lilies, one of the prettiest household plants in existence, are no exception. Let’s take a look at what causes peace lily root rot so we can act and save our beloved plants from getting sick!

Overwatering: The most common culprit

Root rot in peace lilies is typically due to overwatering, a mistake even the most seasoned gardener can make. To keep your plant healthy and vibrant, it’s best to let its soil dry out more than other plants may prefer before you water again. Unnecessarily wet soils are inviting homes for bacteria and fungi which will wreak havoc on the roots of such delicate flowers when allowed too much moisture!

Poor drainage: Don’t let your peace lily drown

While overwatering can be a major factor in peace lily root rot, lack of drainage can make this problem even worse. If the soil is unable to expel excess water, it will eventually accumulate in the pot and cause suffocation of roots, leading to decay. To test your current drainage conditions, observe if there are any pools on top of the soil after you have watered your peace lily – this could indicate that better drainage is needed!

Poor potting mix: Quality matters

When selecting a potting mix for your peace lily, ensure you choose one that offers optimal health benefits. An ideal mix should be light and airy with excellent drainage capabilities to prevent water from pooling or becoming overly saturated – this can stifle the plant’s root system and lead to dangerous rot. A good quality blend will possess these characteristics plus allow oxygen-rich breathability so the roots can do their job effectively.

Over fertilization: Too much of a good thing

Fertilizer can be a beneficial addition to your peace lily’s environment, but it is essential not to overdo it. Excess fertilizer in the soil will create a hazardous atmosphere for the plant’s roots and disrupt their ability to absorb water and nutrients. The excess of nitrogen could even damage the fine root hairs! So remember, make sure you adhere closely to what the manufacturer has suggested on how much fertilizer should be used. Don’t exceed that amount or else you might do more harm than good!

Lack of light: Your peace lily needs sunlight

While peace lilies can tolerate low light conditions, they still need some exposure to sunlight to stay healthy. Without enough light, the plant’s metabolism slows down, and it can become more susceptible to diseases like root rot. Make sure your peace lily is getting enough light by placing it near a bright window or under a grow light.

Poor airflow: A recipe for disaster

Peace lilies, like all houseplants, require good airflow to thrive. Poor ventilation can lead to an environment with stagnant moisture and increase the chances of root rot. To ensure your peace lily remains healthy and in top condition, ensure there is ample space around it for air circulation; additionally, avoid placing it somewhere humid.

Extra large pot: Size matters

While it may appear to be a great idea to provide your peace lily plenty of room for growth, utilizing an overly large pot can result in more damage than benefit. If there is too much soil present in the pot, it will keep moisture for far too long and consequently cause root rot. Decide on a holder that is slightly larger than the plant’s existing container, and only repot when absolutely needed.

Fungal or bacterial attack:

Peace lily root rot is caused by a variety of fungal and bacterial organisms. The most common culprits are Phytophthora parasitica, Pythium spp., and Fusarium oxysporum. These organisms can enter the root system through wounds, and if the soil is constantly wet (contributing to an overwatered peace lily root rot) or lacks proper drainage, the fungi can begin to take hold and spread.

Supplies needed

To repot a peace lily with root rot, you will need the following supplies:

  • Garden shears or pruners
  • Disinfectant
  • New pot with drainage holes
  • Fresh potting mix
  • Fungicide
  • Bleach
  • Watering can or spray bottle

Step 1. Take the plant out of the pot: 

The first step is to take the Peace lily out of its pot. To do this, gently hold the main stem of the plant and tilt the pot to the side. The plant should slide out of the pot easily. If it doesn’t, tap the sides of the pot to loosen the soil.

Step 2. Examine the roots and wash away the soil: 

After you have removed the plant from its pot, assess the roots delicately. Use a gentle stream of water to carefully expose the surrounding soil and uncover those hidden roots.

Step 3. Prune damaged roots: 

With garden shears or pruners in hand, snip away any decayed and damaged roots. Keep only the strong and healthy ones intact, while erring on the side of caution by not exceeding a third of all root systems.

Step 4. Spray fungicide and soak in a bleach solution: 

After pruning, spray the remaining roots with fungicide. You can also soak the roots in a solution of one-part bleach to ten parts water for an hour to eliminate any remaining bacteria or fungi.

Step 5. Choose a new pot with drainage holes: 

Choose a new pot with drainage holes. Make sure it is slightly larger than the previous one to allow for growth.

Step 6. Add fresh potting mix: 

Fill the new pot with fresh, well-draining potting mix. Add enough potting mix to fill one-third of the pot.

Step 7. Put the plant back in the pot: 

Place the Peace lily back in the pot, making sure the roots are spread out. Add soil from all sides and ensure there are no air pockets left. Gently press the soil down with your hands.

Step 8. Water the plant: 

When you have finished repotting the plant, make sure to give it a thorough dousing. You can use either a watering can or spray bottle for this purpose; however, do not overdo it! Be mindful to check the soil consistently and only water when necessary— specifically when its dryness has become apparent.
