CARE GUIDE

How to keep Arum Pictum.

Light

Autumn arum originates from habitats like forest understories and rocky sites, where it occurs in natural shade. It prefers partial sun but can tolerate full sun or full shade, showing its versatile and hardy nature.

Temperature

Autumn arum demonstrates good adaptability to temperature, able to withstand higher heat and wide temperature fluctuations. In hot conditions, you should pay attention to watering and provide appropriate shade to avoid sunburn. On the other hand, autumn arum is relatively intolerant of low temperatures; although it can handle some cold, excessively low temperatures may cause frost damage.

Fertilizer

For Autumn arum, the primary time to apply fertilizer is in early spring while the flowers are forming. The appropriate fertilizer promotes better blooms and helps Autumn arum produce attractive flowers. Fertilizing in early spring ensures strong flowers during the season and supplies energy for dormant growth phases.
