Best Conditions for Growing Lemon Thyme

Ensure the following five growth conditions, and you will have Lemon Thyme in your garden year after year without much fuss. 

1. Light 

The plant thrives in bright sunny locations. The more sun, the better it will grow. It can tolerate partly shady areas. However, it must be noted that the plant will not give the best foliage or the best aroma and flavor in anything but bright sunlight. The plant will do well on a sunny window sill or a patio with streaming sunlight.

2. Water

You can water Lemon Thyme till the soil soaks up the water and drains the excess well. Then you can forget about the plant for a couple of weeks. It will require watering again only once the soil is completely dry to the touch—very low maintenance and so easy. 

3. Soil

Thinking of soil, you can take a hint from its native soil conditions; the rocky limestone mountainsides of the Mediterranean. The conditions here are dry and sandy, and have the ideal alkaline soil perfect for Lemon Thyme. However, you don’t need to hunt for rocky limestone-rich soil as the plant adapts well to most types of soil as long as it is not too damp and drains well. 

4. Fertilizer/feeding

Like all herbs, you do not have to fertilize Lemon Thyme plants. They only need some good organic compost at planting time and occasionally after that. It is a good idea to add some compost at the beginning of the growing season in the spring to encourage profuse growth.

5. Temperature 

Summer temperatures are perfect for Lemon Thyme. They will reward you with luscious green leaves and a heavenly citrus fragrance when the plants’ peak in the summer. This is the time when they bloom tiny lilac flowers. Warm, dry weather is a must for these plants. In cooler temperatures, the plant will go dormant even though remaining green. 

Propagating Lemon Thyme

You can’t have enough of a good thing. This certainly is true of Lemon Thyme. This is a versatile plant. It is widely used in cooking to enhance and garnish various dishes. It is also useful as an insect repellent, especially for mosquitoes. Many home remedies start with a few sprigs of Lemon Thyme. 

This plant in your garden serves two purposes. One acts as a pollinator, and the other acts as a repellent of unwanted pests. 

You can have a ready supply of plants and harvest sprigs if you know how to propagate. There are three ways in which this can be done. 

Lemon Thyme in Garden

• Growing from seed

The first step is to mix moist sandy soil with aged compost in a tray. Two or three seeds should be placed in a cell. Keep the tray warm with a domed cover. You can place it in bright sunlight or under a grow light. A heating mat will also help. 

Once the seeds have germinated, remove the dome and allow air to circulate. Good air circulation helps create plants with a sound root system and robust growth. 

Plant the plants in pots or outdoors when they reach three to four inches in height.  

• Planting cuttings

This is the simplest way to propagate Lemon Thyme. Prepare a pot with a soil mix that drains well. Then cut sprigs from an existing plant. The sprigs should avoid the woody area of the stem and consist of the top half of the sprig. The leaves at the top should be left intact, while the leaves at the bottom should be removed carefully. Then the sprigs can be placed into the soil till parts of the stem are covered, leaving the other part exposed with leaves. The soil should be moist. The pot can be kept under a dome in bright sunlight or under grow lights. When the sprigs show new growth of leaves, they can be transferred to individual pots or outdoors as required.

• Division of roots

This, again, is another assured method of propagating Lemon Thyme. Old plant clusters can be divided carefully from the roots and planted in pots. The potting mix is essential and is the base for the growth of the plant divisions. The well-draining soil and the correct moisture will ensure that the plants grow into new healthy shrubs. 

A Few Tips on Growing in Pots

1. Choose a pot of medium size. This is roughly a one-gallon pot. A pot of this size can be easily moved around to ensure optimum conditions. 

2. Fill the bottom three inches with small rocks. This is done to help drain the soil in the pot. This way, the soil stays moist but not wet. 

3. Although Lemon Thyme plants do not need fertilizing, adding some fertilizer along with the compost may be a good idea to replace the nutrients washed away by drainage.

4. Check on your plants and move them around to get the best sunlight and air circulation. Air circulation is important to herbs. Plants that are well-aerated grow more robustly and are healthier.

Pruning and Maintenance.

Showering a little love and care always pays when it comes to gardening. Clean around the Lemon Thyme shrubs. Remove dead sprigs and prune some branches to let in air and light. This is also an excellent time to add some compost to the plant

Managing Pests and Diseases.

This plant can be troubled by ants and spider mites during the dry season. A light insecticide soap will take care of this. If the conditions around the Lemon Thyme plant are humid and damp for long periods or if soil drainage is insufficient, mold and root rot can set in. Well-draining soil will ensure that these diseases are kept at bay. When you find plants with diseases, remove them immediately before it spreads to other plants. 

In extreme cases, consider changing the position of the plant in the garden or repotting. Bright sunlight will take care of most problems of Lemon Thyme plants
