English lavender, Lavandula augustifolia, is a member of the mint family and considered a perennial herb. Despite its name, it is a Mediterranean plant. It rose to popularity in England during the 18th century and became wildly popular throughout Europe and North America. The plant is known for its fragrant pink flowers and gray-green foliage. It can reach heights and spreads of 3 feet and can be grown in hardiness zones 5 through 8.
Choose a sunny planting site that has well-draining soil.
Test the pH of your growing soil. You can purchase a soil-testing kit at a garden center or plant nursery. English lavender should be planted in soil that has a pH between 7.0 and 7.5. If your soil is below 7.0 you will need to amend the growing site with lime. If the soil is above 7.5 you will need to amend the soil with peat moss.
Acquire lime or peat moss, if needed. Determine how much amendment to add based on the label instructions. Use a pitchfork to break up the soil and work in any amendment needed to bring your soil into the proper pH level.
Dig planting holes 4 to 5 inches wider and deeper than the plant's root ball or container. When planting more than one English lavender, space them 4 feet apart.
Place the plant into the hole and backfill with soil. Fill the hole with water. After the water has drained, add more soil if the dirt has fallen below ground level.
Plan to water weekly if your area does not receive 1 inch of rain weekly.
Add a thin layer of pine bark around your plant. This will keep weeds at bay and improve the soil's water retention.
Avoid fertilizing. The amendments you made to the growing soil when planting are sufficient.
Encourage new growth by pinching off dead blooms.
