Philodendron ‘Spiritus Sancti’ Care: The Complete Guide

Philodendron 'Spiritus Sancti' is the holy grail for plant enthusiasts, known for its slender, elongated leaves and air of mystique ✨ As a rare and sought-after species, this plant demands a bit more attention and care, but the reward is a stunning showpiece that stands out in any collection.

THE SCIENCE

Family: Araceae

Genus: Philodendron

Commonly: holy grail, Santa Leopoldina

THE BASICS

WATER

Philodendron 'Spiritus Sancti' enjoys consistently moist soil, but overwatering is a common pitfall. Water when the top inch of soil feels dry, ensuring thorough watering that allows excess water to drain completely. The goal is to keep the soil evenly moist but never soggy.

LIGHT

This rare Philodendron thrives in bright, indirect light. While it can tolerate lower light levels, optimal growth and vibrant leaf coloration are achieved with bright, filtered light. Avoid direct sunlight, which can scorch the leaves.

HUMIDITY & TEMP

'Spiritus Sancti' flourishes in high humidity, ideally between 60-80%. Maintaining a warm environment with temperatures ranging from 65-80°F will keep this tropical beauty happy. Low humidity and cold drafts can cause leaf edges to brown and curl.

Pro-tip: Create a humidity microclimate by grouping this plant with other humidity-loving plants or using a pebble tray filled with water beneath the pot. Check out Humidity 101 to learn more!

THE NITTY GRITTY

SOIL

Plant your ‘Spiritus Sancti’ in a well-draining, airy potting mix that mimics its natural epiphytic environment. A mix of orchid bark, perlite, and peat works wonders, providing the right balance of moisture retention and aeration - aka our Signature blend, Dirt Bag!

FERTILIZING

A balanced liquid fertilizer during the growing season will keep your Philodendron well-fed and help sustain full, healthy growth!

Dilute to half-strength or stop fertilizing in the fall and winter when the plant is heading into dormancy.

Incorporate our Arber Plant Food during your routine waterings to promote lush, bright foliage 🌿

PESTS

'Spiritus Sancti' is relatively pest-resistant but keep an eye out for pests like spider mites, mealy bugs, and thrips.

Regularly inspect the underside of the leaves and stem joints for hiding pests.

Pro-tip: Gently wiping the leaves with a damp cloth prevents dust build-up and deters pests from setting up camp.
