How to Grow and Care for Lavender

Light: Place Phenomenal Lavender in a location that receives at least 6-8 hours of direct sunlight daily. Full sun is essential for healthy growth and abundant blooms.

Soil: Use well-draining soil with a slightly alkaline to neutral pH (6.5 to 7.5). Sandy or loamy soils are ideal, as they prevent water retention.

Water: Water deeply but infrequently. Allow the top 1-2 inches of soil to dry out between waterings. Overwatering can lead to root rot.

Fertilizer: Apply a balanced, slow-release fertilizer in early spring. Use a low-nitrogen formula (e.g., 5-10-10) to encourage blooming without excessive foliage growth.

Pruning: Prune in early spring or after blooming in late summer. Remove dead or damaged stems and shape the plant to promote bushiness. Avoid cutting into woody stems. Prune like a pro and watch your lavender burst into vibrant blooms

Propagation: Propagate Phenomenal Lavender through cuttings. Cuttings taken in spring or early summer root easily in moist soil.

Pests and Diseases: Monitor for pests such as aphids and spider mites. Use insecticidal soap if needed. Ensure good air circulation to prevent fungal diseases and avoid overwatering, leading to root rot.
