watering

Jacob's ladder will need to be watered frequently especially during periods of hot and dry weather. Aim to water this plant weekly, and always ensure the soil is evenly moist (not overly wet or overly dry). Water gently and thoroughly so that all the soil is moistened. Do not water the foliage directly, as this could cause disease and damage the leaves. Increase watering frequency during the hottest summer months and when the soil surface is completely dry. Reduce watering frequency in the cooler months when growth slows. An occasional misting of the foliage can help prevent dust accumulation.

sunlight

Jacob's ladders prefer bright sunlight in the morning, but need protection from intense afternoon sun. It also depends on the location and climate; for instance in hotter climates provide dappled shade throughout the day, whereas in cooler climates they can receive full sun for most of the day. Generally, 6-8 hours of sunlight is ideal, and it's recommended to keep them out of direct, hot sunlight from noon until late afternoon.

pruning

Jacob's ladder should be pruned once a year, typically in spring. Pruning for this plant species should be light and done judiciously. It is best to prune only dead or dying foliage and remove any diseased or bug-infested branches. When you prune, you should focus on removing any crossing or overcrowded branches, as well as any that lack structure or have a poor growth habit. Pruning should leave the plant with an open, vase-like shape. If you wish to form a more compact plant, prune lightly around the edge of the plant to keep its height and width low.
