How To Grow Lemongrass From Seeds: A Step-By-Step Guide

Lemongrass, with its delightful citrus fragrance and versatile culinary uses, is a popular herb to grow in gardens or containers. While it's commonly propagated from stalks or divisions, growing lemongrass from seeds can be an exciting and rewarding experience. In this step-by-step guide, we will walk you through the process of growing lemongrass from seeds, from seed selection to harvesting. So, let's get started and bring the fresh and vibrant flavours of lemongrass to your garden or home.

Step 1: Seed Selection

Start by obtaining high-quality lemongrass seeds from a reputable seed supplier or store. Look for fresh seeds that are viable and free from any signs of damage or deterioration.

Step 2: Preparing the Seeds

To improve germination rates, soak the lemongrass seeds in warm water for 24 to 48 hours before sowing. This process helps soften the seed coat and promotes faster and more successful germination.

Step 3: Seed Starting Mix

Prepare a well-draining seed starting mix by combining equal parts of compost, peat moss, and vermiculite or perlite. Fill seed trays or small pots with the seed starting mix, leaving about half an inch of space at the top.

Step 4: Sowing the Seeds

Sow the lemongrass seeds on the surface of the seed starting mix, gently pressing them down. Aim to sow one to two seeds per pot or cell, spacing them about an inch apart. Lightly sprinkle a thin layer of the seed starting mix over the seeds to cover them.

Step 5: Watering and Moisture

Moisten the seed starting mix using a spray bottle or a gentle watering can. Avoid overwatering, as excess moisture can lead to rotting. Keep the seed trays or pots consistently moist by misting them regularly or covering them with a clear plastic dome or plastic wrap to create a humid environment.

Step 6: Germination

Place the seed trays or pots in a warm location with temperatures around 70-85¡ãF (21-29¡ãC) to facilitate germination. Keep them in a well-lit area, but avoid direct sunlight at this stage. Germination typically takes about two to three weeks, but it can vary.

Step 7: Transplanting

Once the lemongrass seedlings have developed a few sets of true leaves and are about 4 to 6 inches tall, they are ready for transplanting. Choose a location in your garden or prepare large pots with well-draining soil.

Step 8: Planting in the Garden

If planting in the garden, prepare the soil by removing any weeds and incorporating organic matter, such as compost. Dig holes that are slightly larger than the root ball of each lemongrass seedling. Space the seedlings about 24 to 36 inches apart to allow for their spreading growth habit.

Step 9: Planting in Containers

If planting in containers, choose pots that are at least 12 inches in diameter and have drainage holes. Fill the pots with a well-draining potting mix, leaving enough space for the root ball of each seedling. Plant one seedling per pot.

Step 10: Watering and Care

Water the transplanted seedlings thoroughly after planting, ensuring that the soil is evenly moist. Maintain consistent moisture levels throughout the growing season, but avoid waterlogged conditions. Lemongrass prefers regular watering rather than drying out completely.

Step 11: Sunlight and Temperature

Place the lemongrass plants in a location that receives full sun for at least 6 to 8 hours a day. Lemongrass thrives in warm climates and prefers temperatures between 70-95¡ãF (21-35¡ãC). Protect the plants from frost, as they are sensitive to cold temperatures.

Step 12: Fertilizing

Feed the lemongrass plants every 4 to 6 weeks with a balanced organic fertilizer or a slow-release granular fertilizer according to the package instructions. This will provide them with the necessary nutrients for healthy growth.

Step 13: Harvesting

You can start harvesting lemongrass when the stalks are about 1/2 inch thick and at least 12 inches tall. Cut the stalks close to the ground using a sharp knife or garden shears. Remember to leave a few stalks behind to ensure the plant's regrowth and continued production.

Frequently Asked Questions (FAQs)

Can I grow lemongrass indoors? Yes, lemongrass can be grown indoors in containers. Choose a large pot with good drainage and place it in a sunny location, such as a south-facing window. Ensure the plant receives at least 6 to 8 hours of sunlight or supplement with artificial grow lights.

How long does it take for lemongrass to grow from seeds? Lemongrass takes approximately 4 to 6 months from seed to reach a harvestable size. However, the growth rate can vary depending on growing conditions and the specific lemongrass variety.

Can I propagate lemongrass from store-bought stalks? Yes, lemongrass can be propagated from store-bought stalks. Place the stalks in a glass of water, and once roots start to develop, transfer them to pots or the garden following the same planting and care instructions.

Can lemongrass survive the winter? Lemongrass is sensitive to frost and cold temperatures. In regions with cold winters, it's best to grow lemongrass as an annual or bring potted plants indoors before the first frost. Alternatively, you can dig up the plants and overwinter them in a frost-free location.

Can I use the leaves of lemongrass for cooking? Yes, the lower white portion of the lemongrass stalk is commonly used in cooking. The outer tough layers are usually removed, and the tender inner portion is minced or sliced and added to various dishes for its aromatic and citrusy flavour.
