nepeta

Nepeta grossheimii should be watered lightly once a week, just enough to keep the soil moist. Ensure that the top 1 inch (2.5 cm) of the soil is allowed to dry out between waterings. Over-watering can lead to root rot, so it should be avoided. In especially warm and dry conditions, you may need to water the plants more frequently. This species should be watered from the bottom rather than the top, as wetting the leaves can lead to fungal diseases.

Nepeta grossheimii is a hardy, drought-tolerant plant that does best in full sun. It should receive at least 6-8 hours of direct sunlight each day in order to thrive; however, if given more, it can also do well. In the spring and summer months, when the days are longer, more sunlight can be beneficial, while during the winter months, direct sunlight will be needed.

Nepeta grossheimii should be pruned twice a year, once after flowering in the early summer, and again during the late winter months. During the summer pruning, any dead, damaged, or diseased stems should be removed, as well as any weak, spindly growth. This will help maintain the desired shape of the shrub and prevent overcrowding. In late winter, any remaining dead foliage can be removed, as well as any unruly, overly large branches. To do this, use sharp pruning shears to cut the branches about 1/4 inch above a bud or leaf node, angling slightly outward away from the center of the shrub. Pruning should be kept to a minimum, since it will reduce the blooms of the plant and can slow growth.
