Potting mix

Use a well-draining potting mix to accommodate the plant’s epiphytic nature. A blend of Aroid mix, bark, and sand will provide the necessary moisture retention and airflow needed for optimum growth.

Watering & Plant Hydration

Keep your plant adequately hydrated, as Philodendron spiritus-sancti thrives in continuously moist conditions. However, be cautious not to overwater, as this can lead to root rot. Adjust your watering frequency based on your potting mix’s drying rate and the establishment of roots, aiming for once a week or every 10 days.

Humidity

Philodendron spiritus-sancti prefers high humidity levels, ranging from 70-80%. While it thrives in such conditions, it can still adapt to lower humidity levels with consistent watering and a well-draining potting mix.

Water Quality & pH

Rainwater, distilled water, or reverse osmosis water are preferable for Philodendron spiritus-sancti, as they mimic the plant’s natural conditions more closely. If using tap water, acidify it to a pH of 6 to enhance nutrient availability and uptake.

Fertilizer & Nutrients

A standard fertilizer routine should suffice for Philodendron spiritus-sancti. Using a soluble orchid fertilizer every second or third watering, along with occasional organic fertilizer applications, will help keep your plant healthy and promote growth.

Light

Philodendrons, including spiritus-sancti, can tolerate more light than many other Aroids. While they thrive in bright light, direct sun should be avoided, as it can lead to leaf burn. Aim for filtered direct sunlight equivalent to 5-25% intensity for a few hours in the morning, supplemented by LED grow lights for the remainder of the day.
