Introduction

Mâche (Valerianella locusta), also known as corn salad, lamb’s lettuce, or field salad, is a cold-hardy leafy green that thrives in cool temperatures. Its tender leaves have a mild, nutty flavor, making it a delightful addition to salads and dishes. Planting mâche in October allows gardeners to enjoy fresh greens throughout the winter and early spring. This comprehensive guide will walk you through everything you need to know about growing mâche in October, from selecting the best varieties to harvesting your crop. With our expert tips, you’ll be well on your way to a successful and rewarding gardening experience.

Why Plant Mâche in October

Cold-Hardy Crop

Mâche is exceptionally tolerant of cold weather and can survive temperatures as low as -5°C (23°F), making it ideal for autumn and winter cultivation. Planting in October takes advantage of the cooler temperatures, which mâche prefers for optimal growth.

Extended Harvest Season

By sowing mâche in October, you can enjoy a continuous supply of fresh greens throughout the winter months when other crops are scarce. Mâche grows slowly during the cold season, allowing for extended harvesting.

Minimal Pest Pressure

Cooler temperatures in autumn reduce the activity of many common garden pests, resulting in healthier plants and a more abundant harvest.

Nutritional Benefits

Mâche is rich in vitamins A, C, and B9 (folate), as well as iron and omega-3 fatty acids. Growing your own ensures access to fresh, nutrient-dense greens during the winter.
