How Deep Does Lemon Verbena Plant Need to Be Planted?

Updated: July 14, 2023

Lemon verbena (Aloysia citrodora) is a popular herb known for its refreshing lemon scent and flavorful leaves. It is commonly used in culinary dishes, herbal teas, and even beauty products. If you are considering growing lemon verbena in your garden, one of the essential factors to consider is the depth at which it should be planted.

Understanding Lemon Verbena

Before delving into the planting depth, let’s first gain a better understanding of lemon verbena itself. Originating from South America, lemon verbena is a perennial shrub that can reach up to 10 feet in height under ideal growing conditions. It features long, slender leaves with a bright green color and a strong citrus aroma.

This herb thrives in warm climates and prefers well-drained soil with a pH level between 6.5 and 7.5. Lemon verbena requires full sun to grow properly and is relatively low-maintenance compared to other herbs. However, it is not very cold-tolerant and may struggle in regions with harsh winters.

Planting Lemon Verbena

When it comes to planting lemon verbena, it is crucial to choose the right location and provide the appropriate conditions. While lemon verbena can be grown from seeds, it is generally easier and more reliable to start with young plants purchased from a nursery or obtained through cuttings.

Choosing the Right Location

Lemon verbena thrives in full sun, so choose a location in your garden that receives at least six hours of direct sunlight per day. In terms of soil, lemon verbena prefers well-drained soil that is rich in organic matter. If your soil tends to be heavy or clay-like, consider amending it with compost or well-rotted manure to improve drainage.

Preparing the Planting Hole

To ensure that your lemon verbena plant has enough room to grow, it is essential to dig a suitable planting hole. The depth of the hole should allow for the plant’s root ball and some extra space for the roots to spread out comfortably. As a general guideline, aim for a planting hole that is twice as wide and deep as the root ball.

Planting Depth

When it comes to the actual depth at which lemon verbena should be planted, the general consensus among gardeners is to avoid burying the plant too deeply. Lemon verbena has shallow roots, and planting it too deep can lead to root rot and other issues.

The top of the root ball should be level with or slightly above the soil surface. Gently place the plant in the center of the planting hole, making sure that it sits upright. Backfill the hole with soil, firming it gently around the roots to eliminate air pockets.

Mulching and Watering

Once the lemon verbena plant is in place, applying a layer of organic mulch around it can help conserve moisture and suppress weed growth. Mulching also helps regulate soil temperature, which is particularly beneficial in regions with hot summers.

After planting, water the lemon verbena thoroughly to settle the soil around the roots. Lemon verbena prefers moist soil, so regular watering is necessary, especially during dry periods. However, be careful not to overwater, as excessively wet conditions can lead to root rot.

Caring for Lemon Verbena

Providing proper care for your lemon verbena plants will help them thrive and produce an abundance of aromatic leaves. Here are some essential care tips:

Watering

As mentioned earlier, lemon verbena prefers moist soil. Water your plants regularly, especially during hot and dry periods. However, allow the soil to dry slightly between watering sessions to prevent waterlogging.

Fertilizing

Lemon verbena benefits from regular fertilization to promote healthy growth and abundant foliage. Apply a balanced, slow-release fertilizer in early spring and again in midsummer. Follow the manufacturer’s instructions for application rates.

Pruning

Pruning lemon verbena is essential to maintain its shape and encourage new growth. Prune the plant in early spring before new growth appears, removing any dead or damaged branches. Regular pruning also helps prevent the plant from becoming too leggy.

Winter Protection

In regions with cold winters, lemon verbena may struggle to survive. Before the first frost, cut the plant back to about 6 inches above the ground. Apply a thick layer of mulch around the base of the plant to insulate the roots from freezing temperatures. Alternatively, you can dig up the plant and overwinter it indoors in a cool, well-lit location.

Conclusion

Lemon verbena is a delightful herb to grow in your garden, adding a burst of citrus fragrance and flavor to your culinary creations. When planting lemon verbena, remember to choose a sunny location with well-drained soil, prepare a suitable planting hole, and avoid burying the plant too deeply. With proper care and attention, your lemon verbena plants will thrive and provide you with an abundance of aromatic leaves for years to come.
