While Thevetia plants are generally hardy and low-maintenance, there are a few issues to watch out for. Some common problems include:

  1. Scale insects: Scale insects can be a problem on Thevetia plants, especially if they are grown indoors. You can control scale insects by using a horticultural oil or insecticidal soap.
  2. Leaf spot: Leaf spot is a fungal disease that can cause brown spots on the leaves of the Thevetia plant. You can prevent leaf spot by avoiding overhead watering and ensuring good air circulation around the plant.
