Tarragon is a delightful herb that adds a unique flavor to many dishes. It is known for its distinct licorice-like taste and is a staple in French cuisine. While tarragon plants are generally easy to grow, it can be frustrating when they start growing sideways instead of upright. In this article, we will explore the reasons behind this phenomenon and provide some tips on how to rectify the situation.

Insufficient Light

One of the common reasons why tarragon plants grow sideways is due to insufficient light. Tarragon is a sun-loving herb that thrives in full sunlight. When grown indoors or in shady areas, the plant tends to stretch towards the light source, causing it to grow sideways or become leggy.

To prevent this from happening, make sure to place your tarragon plant in an area that receives at least six hours of direct sunlight each day. If you are growing it indoors, consider using artificial grow lights that mimic natural sunlight. This will help ensure that your tarragon grows upright and healthy.

Improper Watering

Another factor that can contribute to sideways growth in tarragon plants is improper watering. Overwatering or underwatering can lead to weak root systems, making it difficult for the plant to support its upright growth.

Tarragon prefers well-draining soil that is slightly moist but not waterlogged. Allow the top inch of soil to dry out before watering again. Avoid watering too frequently or letting the plant sit in standing water, as this can lead to root rot. By maintaining proper watering practices, you can promote healthy root development and encourage upward growth.

Lack of Nutrients

A lack of essential nutrients can also cause tarragon plants to grow sideways. Tarragon requires a balanced fertilizer with equal parts nitrogen, phosphorus, and potassium (NPK). Nitrogen promotes leafy growth, phosphorus supports root development, and potassium helps with overall plant health.

To ensure your tarragon plant receives an adequate supply of nutrients, regularly fertilize it during the growing season. Use a slow-release organic fertilizer or a liquid fertilizer diluted to half strength. Follow the instructions on the fertilizer packaging for application rates and frequencies. By providing the necessary nutrients, you can encourage your tarragon plant to grow upright and thrive.

Lack of Pruning

Pruning is an essential practice for maintaining the shape and growth of tarragon plants. If you neglect to trim your tarragon regularly, it can become leggy and start growing sideways. Pruning encourages bushier growth and prevents the plant from becoming top-heavy.

When pruning tarragon, remove any dead or damaged leaves and stems. Cut back about one-third of the plant’s overall height to promote new growth from the base. This will help maintain a compact and upright form while preventing sideways growth.

Pests and Diseases

Pests and diseases can also affect the growth of tarragon plants, causing them to grow sideways or become weak. Common pests that attack tarragon include aphids, spider mites, and whiteflies. These pests suck the sap from the leaves, weakening the plant over time.

Inspect your tarragon plant regularly for any signs of pest infestation. If you notice small insects, webbing, or discoloration on the leaves, take immediate action to control the problem. Use insecticidal soap or neem oil to eliminate pests effectively. Additionally, ensure good air circulation around the plant to prevent fungal diseases that can weaken its structure.

Supporting Sideways Growth

If your tarragon plant has already grown sideways, there are ways to support its growth and encourage it to grow upright again. One method is staking. Insert a stake into the soil near the base of the plant and gently tie the stems to the stake using garden twine. This will provide support and help the plant grow vertically.

Another option is to use a plant cage or trellis. Place the cage or trellis around the tarragon plant, allowing it to grow through the gaps. This will guide the plant’s growth upwards and prevent further sideways growth.

Conclusion

Growing tarragon is a rewarding experience, but it can be frustrating when your plants start growing sideways instead of upright. By addressing common issues such as insufficient light, improper watering, lack of nutrients, lack of pruning, pests, and diseases, you can help your tarragon regain its upright growth pattern. Remember to provide adequate sunlight, water appropriately, fertilize regularly, prune consistently, and monitor for pests and diseases. With proper care and attention, your tarragon plant will flourish and provide you with a bountiful harvest of flavorful leaves.
