Can You Plant Potatoes, Tarragon, and Lavender Together?

Companion planting is a technique gardeners use to boost plant health, increase yields, and manage pests naturally. When considering whether potatoes, tarragon, and lavender can be grown together, it’s essential to understand their compatibility. This article explores the benefits and challenges of planting these three together, providing practical tips for success.

Compatibility Analysis

Can you plant potatoes, tarragon, and lavender together? The short answer is NO. While each of these plants has its unique benefits, they have different growth requirements that make them less than ideal companions.

• Potatoes thrive in nutrient-rich, slightly acidic soil and require consistent moisture.
• Tarragon prefers well-drained, moderately fertile soil and can tolerate dry conditions.
• Lavender needs well-drained, alkaline soil and minimal watering.

These differences in soil and water needs make it challenging to grow them together successfully. Additionally, lavender’s strong scent can repel pests that might otherwise benefit potato plants.
