Preventing Rot in Your Arrow Plant:
Causes and Solutions

Arrow plants, also known as arrowheads or syngoniums, are popular houseplants due to their attractive foliage and ease of care. However, a common issue that arrow plant owners face is rot. Rot can be caused by a variety of factors, including overwatering, poor drainage, and fungal or bacterial infections. In this article, we’ll explore the causes of rot in arrow plants and offer solutions for preventing and treating it.

Causes of Rot in Arrow Plants

Overwatering

Overwatering is the most common cause of rot in arrow plants. When the soil is constantly wet, the roots suffocate and begin to rot. Signs of overwatering include yellowing leaves, wilting, and a foul odor coming from the soil.

Poor Drainage

If your arrow plant is not planted in well-draining soil or if the pot does not have drainage holes, excess water can accumulate at the bottom of the pot and cause root rot.

Fungal or Bacterial Infections

Fungal or bacterial infections can also cause rot in arrow plants. These infections can be spread through contaminated soil, water, or even tools used for pruning.

Solutions for Preventing and Treating Rot

Watering

To prevent overwatering, allow the top inch of soil to dry out before watering again. Make sure your arrow plant is planted in well-draining soil and that the pot has drainage holes to allow excess water to escape. If you notice signs of overwatering, stop watering immediately and allow the soil to dry out before resuming watering.

Soil

To improve drainage, mix perlite or sand into the soil when planting your arrow plant. This will help excess water to drain away from the roots. If you suspect that your plant has root rot due to poor drainage, repot it into fresh, well-draining soil.

Fungal or Bacterial Infections

To prevent fungal or bacterial infections, make sure to keep your arrow plant clean and free from debris. Water your plant at the base rather than overhead to avoid splashing water onto the leaves. If you notice any signs of infection, such as black or mushy spots on the leaves or stems, remove affected parts immediately and dispose of them in a sealed bag.
