Cultivation of Origanum laevigatum ‘Herrenhausen’:

Growing Origanum laevigatum ‘Herrenhausen’ is relatively straightforward. Consider the following factors when cultivating this beautiful oregano variety:

Sunlight: Oregano ‘Herrenhausen’ thrives in full sun exposure. Ensure that the plant receives at least 6-8 hours of direct sunlight daily to promote healthy growth and abundant flowering.

Soil and Drainage: Well-drained soil is crucial for the success of this oregano cultivar. It prefers average to dry moisture levels and is well-suited to gritty, sandy loams. Avoid highly acidic or poorly drained soils, as they can impede proper growth and development.

Watering: Once established, Oregano ‘Herrenhausen’ is relatively drought-tolerant and does not require excessive watering. However, regular watering during dry periods can help maintain optimal growth. Aim to keep the soil slightly moist but not overly saturated.

Fertilization: This oregano variety generally does not require heavy fertilization. It can thrive in average soil conditions without the need for frequent feeding. However, if desired, a light application of balanced fertilizer once or twice during the growing season can provide additional nutrients for healthy growth.

Pruning and Maintenance: To keep the planting tidy and promote the growth of new leaves, it is recommended to shear the plants back regularly before flowering. This practice helps maintain the plant’s shape and encourages fresh foliage growth. Additionally, removing spent flowers can prolong the flowering period and enhance the plant’s overall appearance.
