3. How to Plant Large Lavender Plants

Mature lavender plants need the right conditions to thrive and establish quickly.

Step-by-Step Planting Guide

✔️ Choose a sunny spot – Large lavender plants need 6–8 hours of full sun daily.
✔️ Improve drainage – Mix grit or sand into the soil if it’s heavy or clay-based.
✔️ Space plants properly – Leave 45–60 cm (18–24 inches) between plants for good airflow.
✔️ Plant at the right depth – Keep the crown level with the soil surface to prevent rot.
✔️ Water deeply but infrequently – Water well when first planted, then only when the soil is dry.

Tip: If planting lavender hedging, space plants 40 cm (16 inches) apart for a dense hedge.

4. Caring for Large Lavender Plants

Tall lavender plants need minimal maintenance but benefit from proper care.

Pruning & Maintenance

✔️ Prune after flowering – Cut back by one-third to maintain shape and encourage fresh growth.
✔️ Avoid cutting into old wood – Always leave some green growth to prevent dieback.
✔️ Remove spent flowers – Helps encourage a second flush of blooms.

Watering & Feeding

✔️ Water sparingly – Overwatering leads to root rot.
✔️ Use a potash-rich feed – Encourages flowering but avoid nitrogen-heavy fertilizers.
✔️ Mulch with gravel – Helps improve drainage and suppress weeds.
