Step-by-Step Guide to Dividing Lemongrass Plants

Follow these steps carefully to divide your mature lemongrass plants correctly.

1. Determine the Right Time to Divide Lemongrass Plants

The ideal time to divide lemongrass is in late winter or early spring when it is dormant. If you do not live in a region with defined seasons, look for signs of slow growth or minimal new leaves appearing.

2. Gather Required Tools and Materials

To divide the plant efficiently, make sure you have all the necessary tools and materials ready. Clean your gardening shears by dipping them in rubbing alcohol before use. A fork or spade will help you dig up the parent plant and separate it into sections.

3. Preparing the Mother Plant for Division

Water the lemongrass plant thoroughly several days before dividing it. This makes it easier to handle while reducing stress on the plant. Next, cut the foliage back to about 6 inches long from the soil's surface, leaving only healthy green leaves. Then, loosen the soil around the base of the plant using a fork or spade to ease its removal from the soil.

4. Separating Lemongrass Clumps

Examine the parent plant and divide it into clumps of two to three stems with separate roots systems. Each clump should contain at least one healthy root system and a few stems with attached leaves. Avoid choosing clumps that are wilted, shriveled, or show signs of root rot or pest infestation.

5. Transplanting Lemongrass Divisions

Plant your divided lemongrass clumps in a container or planting bed filled with well-draining sandy soil. Set the clumps about 2 inches deep and 8 inches apart, adding some compost or slow-release fertilizer to each hole. Gently tamp the soil around the roots of the plant, making sure it is firmly in place. Finally, water the newly transplanted plants thoroughly.

Lemongrass Plant Care After Division

After dividing your lemongrass plants, you will need to follow some essential care tips for healthy growth:

1. Watering Lemongrass Plants

Water newly transplanted lemongrass divisions promptly and regularly until new growth appears. After that, reduce watering to once or twice a week or depending on environmental conditions, so the soil remains moist but not soaked. Overwatering can lead to root rot, while underwatering can cause wilting or stunted growth.

2. Fertilizing Lemongrass

As a fast-growing grass, lemongrass responds well to organic fertilizers containing nitrogen, phosphorus, and potassium. Apply a balanced slow-release fertilizer every two months, or side-dress the plants with compost or manure. Doing so promotes healthy foliage growth and reproduction.

3. Protecting Lemongrass from Pests and Diseases

Lemongrass is usually pest-free, but you can occasionally encounter aphids, spider mites, snails, or slugs in humid conditions. Natural predators like ladybugs or neem oil are effective at controlling infestations. Alternatively, if the problem persists, use an organic insecticide for optimal results.

In dividing lemongrass plants is an easy and practical way to expand your herb garden while improving the health of parent plants. With our comprehensive guide on how to divide lemongrass, you should be able to achieve productive growth with minimal stress.
