Ploughman's spikenard

Ploughman's spikenard (Inula conyza) should be watered moderately, about once per week in warmer climates and every other week in cooler climates. The soil should be allowed to dry out between watering and a light finger test can help determine the need to water. Avoid over-watering as this can cause the roots to rot and cause the plant to die. Instead, err on the side of caution and water less than more. Water when the soil begins to feel dry to the touch but before it is bone dry.

Ploughman's spikenard (Inula conyza) is a perennial plant that prefers full sun for optimal growth. For best results, the plant should receive at least 6 to 8 hours of direct sunlight each day. It is especially important to provide plenty of direct sunlight in the morning, as it helps to energize the growing process more effectively. Too much shade can cause the plant to become weak and prone to disease.

Ploughman's spikenard (Inula conyza) should be pruned at least twice a year, during late winter and early summer. In late winter, lightly prune back the overall plant. This removes any winter-damaged foliage and encourages new and healthy growth. In early summer, repeat this light pruning but focus on deadheading any spent blooms. This allows for regrowth and additional blooms in the summer. To maintain the shape and size of the plant, trim any unruly branches back to the desired shape. When pruning Ploughman's spikenard, use sharp pruning shears and be sure to disinfect them before and after use.
