Tips for caring for Iris plants

To ensure that your Iris plants bloom beautifully year after year, it is essential to provide them with proper care. Here are some tips on how to care for Iris plants:

  1. Soil and sunlight: Iris plants thrive in well-draining soil and full sunlight. Make sure that the soil is not too wet, as Iris plants can be susceptible to rot if the soil is too moist.

  5. Division: Iris plants should be divided every three to five years to prevent overcrowding and ensure continued blooming.
