Lavender, with its beautiful purple flowers and calming scent, is a popular choice for gardeners and landscapers alike. However, like all plants, lavender has its own set of preferences and dislikes when it comes to companion planting. In order to ensure the health and success of your lavender plants, it’s essential to know what plants to avoid planting near them. In this article, we’ll delve into the world of lavender companion planting and explore the plants that should be kept at a distance.
Understanding Lavender’s Needs
Before we dive into the specifics of what not to plant near lavender, it’s crucial to understand the needs of this lovely herb. Lavender is a low-maintenance plant that thrives in well-draining soil and full sun. It’s also relatively drought-tolerant, making it an excellent choice for water-conscious gardeners.
