Growing Tuscan Blue Rosemary: A Comprehensive Guide
Introduction
Rosemary is a versatile and fragrant herb that’s easy to grow and has many culinary and medicinal uses. One popular variety is Tuscan blue rosemary, known for its stunning blue flowers and hardiness. This guide will provide you with all the information you need to successfully grow and care for Tuscan blue rosemary plants.
Growing Tuscan Blue Rosemary
Choosing a Location
Tuscan blue rosemary prefers full sun and well-drained soil. It can tolerate partial shade, but it will produce more flowers in full sun. The plant is hardy to USDA zone 8, meaning it can survive temperatures down to 15 degrees Fahrenheit (-9 degrees Celsius). If you live in a colder climate, you can grow Tuscan blue rosemary in a container and bring it indoors for the winter.
Planting
To plant Tuscan blue rosemary, dig a hole twice the width of the root ball and just as deep. Place the plant in the hole and backfill with soil, tamping down gently to remove any air pockets. Water the plant deeply after planting.
Care
Watering
Tuscan blue rosemary is drought-tolerant, but it will produce more flowers if it’s watered regularly, especially during hot, dry weather. Water the plant deeply, allowing the soil to dry out slightly between waterings. Avoid overwatering, as this can lead to root rot.
Fertilizing
Fertilize Tuscan blue rosemary once a month during the growing season with a balanced fertilizer. Stop fertilizing in the fall and winter.
Pruning
Tuscan blue rosemary can grow up to 7 feet tall and 2 feet wide. If you want to keep your plant more compact, you can prune it back heavily (by as much as half) in the spring, after it has finished blooming. Pruning will also encourage new growth and flowering.
Harvesting
You can harvest Tuscan blue rosemary leaves anytime throughout the year. Simply snip off the leaves as needed. The flowers can also be harvested and used fresh or dried.
Overwintering
In cold climates, Tuscan blue rosemary can be overwintered by heavily mulching it in the fall and planting it in a spot that’s sheltered from the wind but still receives full sun. You can also grow Tuscan blue rosemary in a container and bring it indoors for the winter.
Troubleshooting
Pests and Diseases
Tuscan blue rosemary is relatively pest- and disease-free. However, it can be susceptible to aphids, spider mites, and whiteflies. Treat infestations with an insecticidal soap or neem oil.
Yellowing Leaves
Yellowing leaves can be a sign of overwatering, underwatering, or nutrient deficiency. Check the soil moisture and fertilize the plant if necessary.
