Phenomenal lavender plants are hardy in USDA zones 5-9 and are known for their tolerance to extreme weather conditions, such as heat and cold. Here are some care instructions for these plants:
1. Soil: Phenomenal lavender plants prefer well-draining, slightly alkaline soil with a pH between 6.5 and 7.5. Amend the soil with organic matter, such as compost or aged manure, to improve drainage and fertility.
2. Watering: Water your plants deeply but infrequently, once or twice a week, allowing the soil to dry out slightly between waterings. Overwatering can cause root rot and other fungal diseases, so make sure the soil is well-draining.
3. Sunlight: Lavender plants require full sun to thrive, at least 6-8 hours of direct sunlight daily. Make sure to plant them in a sunny location, away from shade or partial shade.
4. Pruning: Prune your lavender plants regularly to promote bushy growth and prevent legginess. Cut back the stems by about one-third in early spring before new growth appears, and again after flowering to shape the plant and remove spent blooms. Avoid cutting too far down the stem and into the woody area.
5. Fertilizer: Phenomenal lavender plants do not require much fertilizer, but you can feed them with a balanced fertilizer, such as 10-10-10, in early spring when new growth appears. Be careful not to over-fertilize, as this can cause excessive growth and reduce the plant's essential oils.
6. Pests and Diseases: Lavender plants are generally resistant to pests and diseases, but they can be susceptible to root rot, fungal diseases, and insect infestations. To prevent these issues, avoid overwatering, provide good air circulation, and inspect your plants regularly for signs of damage or infestation.
7. Height and Width: Phenomenal lavender plants can reach a height of 2 to 3 feet (60 to 90 cm) and a width of 2 to 3 feet (60 to 90 cm), making them a great choice for borders, hedges, or containers.
8. Winter Protection: Phenomenal lavender plants are hardy, but they may require some winter protection in colder zones. Mulch the plants with a layer of straw or shredded leaves in the fall to protect the roots from freezing and thawing cycles.
By following these care instructions, you can help your lavender plants thrive and produce fragrant blooms that will add beauty and fragrance to your garden.
