Philodendron Martianum 'Fat Boy'

This plant thrives in bright indirect light, which means it needs a well-lit space without harsh direct sunlight. Ideal locations include east or north-facing windows, or spots near south or west-facing windows with filtered light through a sheer curtain to protect its foliage.

Water when the top 1–2 inches of soil feel dry. Avoid overwatering & ensure pots have drainage holes. Frequency may vary with season and light, roughly once every 5–10 days.

30–40% Coco Coir/Peat Moss: For moisture retention.
20–30% Perlite/Pumice: Ensures excellent drainage and aeration.
20–30% Orchid Bark (small): Promotes airflow and mimics natural conditions.
10–20% Vermicompost/Compost: Provides slow-release nutrients.

Optional: A handful of horticultural charcoal for added benefit. This blend supports healthy roots and prevents rot in our high humidity.

For these plants, use a balanced liquid fertilizer (like 20-20-20 or 10-10-10) diluted to half strength every 2–4 weeks during the growing season. They prefer light, consistent feeding over heavy applications. A slow-release fertilizer at the start of spring can also support healthy growth. In winter, pause feeding as these plants enter a resting phase.
