Philodendron ‚Orange Marmalade‘ - Care

The Orange Marmalade prefers bright conditions, but it doesn't tolerate full sun well – the leaves tend to scorch quickly. Mild morning or late evening sun is usually well tolerated, so a spot on an east or west-facing window with plenty of indirect light works well. Light also directly influences color intensity: with too little light, new leaves will emerge paler or greener instead of a vibrant orange; a brighter location best showcases its typical splendor.

Water thoroughly when the top layer of soil (roughly the top 3–5 cm) has dried out, until water drains from the bottom. Waterlogging is the most common care mistake and quickly promotes root rot – a pot with good drainage is therefore essential. During the growing season, this is usually the case about every 7 to 10 days, and less often in winter. The finger test is more reliable than a fixed schedule.

During the growth phase, feeding every 4 to 6 weeks with a diluted, balanced liquid fertilizer is usually sufficient. The exact amount depends on the specific product and its concentration – it's best to follow the dosage instructions on the packaging rather than a general rule. The Orange Marmalade doesn't have a pronounced winter rest period: if it's just by a window, you can still reduce fertilization in autumn and winter because growth slows down due to weaker light. However, if a plant lamp runs with sufficient daylight hours, growth activity remains relatively stable even in winter – then fertilization can continue at the usual rhythm instead of being reduced.

We consciously alternate between different fertilizers for our own plants – currently including COMPO COMPLETE, Foliage Focus, Liquid Gold Leaf, and Hesi TNT-Complex, supplemented with Hesi Root Complex, Hesi PowerZyme, and CalMag as needed.

It should be loose and well-draining – an aroid mix of e.g. soil, orchid bark, and perlite has proven effective. Heavy, compacted soil promotes waterlogging and thus root rot.

The Orange Marmalade is a true houseplant: It thrives in normal indoor air conditions and is described as particularly well-suited to average household humidity levels, so a humidifier isn’t a must. However, a bit more humidity (50 to 70 %) promotes stronger leaves and more vibrant colors, if you have the option. Mist spraying barely increases humidity and only for a few minutes; at the same time, it leaves the leaves damp, which can create a breeding ground for fungi and bacteria, especially with poor air circulation. A tray of water or a group of plants is the more reliable choice here, if desired. Temperatures between 18 and 27 °C are optimal; the plant should be kept away from drafts and temperature fluctuations as much as possible.

The Orange Marmalade grows upright, compactly, and independently by nature, so a support stake isn't strictly necessary. If you want it to grow larger and mature more robustly, you can still offer it a moss stick for its aerial roots to attach to – this promotes a fuller, more mature appearance. Rotating the plant evenly ensures consistent growth in all directions, as it would otherwise lean towards the light source.
