Soil

These plants thrive in well-draining, fertile soil. Amend the soil with organic matter to improve drainage and provide essential nutrients.

Watering

Water arum lilies regularly, especially during active growth. Allow the soil to dry slightly between waterings to prevent overwatering.

Fertilizing

Fertilize your arum lilies with a balanced fertilizer during the growing season. Avoid overfertilizing, as it can lead to excessive foliage growth and reduced flowering.

Temperature

Arum lilies are not tolerant of frost. In cold climates, grow them as houseplants or move them indoors during the winter months.
