CARE GUIDE

How to keep Oxybaphus Nyctagineus.

Light

Wild four o'clock prefers being in areas with plentiful sunlight throughout the day. In its native habitat it performs best where it gets the sun for most of the day. Still, it can tolerate locations with somewhat reduced sunlight. Excessive shade can cause the plant to perform poorly, while too much sun can result in leaf scorching.

Temperature

The wild four o'clock is native to North America and occurs in a temperature range of 0 to 38 ℃ (32 to 100 ℉). It prefers warm daytime temperatures and cooler nighttime temperatures. In the summer it may benefit from partial shade to prevent heat stress.

Fertilizer

Generally, a single fertilizer application in spring is adequate for Wild four o'clock, though repeated feedings can enhance growth. Fertilize every month to every six weeks. Feeding improves the leaves' appearance and function, helping maintain uniform color and a healthy texture. It also promotes root development and nutrient uptake, supporting the plant's long-term health.

Pot & Repot

When repotting Wild four o'clock, choose a pot 1-2 inches (2.5–5.1 cm) larger with ample drainage. Use a well-draining potting mix. Repot in spring or fall, making sure the root ball sits slightly lower than the rim of the flower pot. Water thoroughly after repotting and place it in a warm spot with indirect sunlight.
