Water your Ptychosperma macarthurii when the soil appears dry. A good rule of thumb is to water the plant when the top inch (2.5 cm) of soil is dry. Be careful not to overwater, as this can damage the plant's root system. When watering, make sure to water the soil deeply to allow for proper air circulation in the roots. Avoid pouring water directly onto the leaves, as this can cause leaf drop and other problems. In general, 1 thorough watering— enough to moisten the soil to the root level— is enough for the plant every 1 to 2 weeks. However, water more frequently when the plant is actively growing in warmer months. In cooler months, when the plant isn't growing, cut back on watering and allow the soil to dry out a bit before you water again.

Ptychosperma macarthurii requires bright, indirect sunlight. It prefers at least 4 hours of sun per day; the more sunlight the better. However, it is important to protect it from direct sunlight, as direct sun can burn the leaves. When kept outdoors, the plant should ideally be in an east or west facing location that is sheltered from the midday sun. When grown indoors, place the plant near a south or west-facing window and use a sheer curtain or blind to filter the light.

Ptychosperma macarthurii needs to be pruned on a regular basis to maintain a healthy shape and promote growth. To prune this plant, you should start by removing any diseased or dead branches in the late winter or early spring. You should then cut back any large branches that have grown too tall or that are growing in an unbalanced manner. After that, you should lightly prune throughout the spring and summer, cutting any longer branches back by a third, or clipping any small branches that have grown too much. This will prevent the plant from becoming unbalanced and overgrown, and will also help to promote new growth. Pruning should be done as needed, and you should avoid pruning too much at once; it is better to do small, manageable amounts of pruning at a time.
