Choosing the Best Seeds to Growing Organic Thyme
There is a different variety of Thyme to choose from for growing in your garden. As one of the world’s oldest aromatherapy and medicinal plants, there are many varieties of Thyme are available.
Here are some of the most popular Thyme varieties you can grow successfully.
French or Common Thyme – The classic kitchen garden Thyme plant, this variety is as tasty as it is beautiful. Common Thyme plant is a dwarf, woody, evergreen. It is grown mainly as an aromatic culinary herb.
Red Creeping Thyme – Because the tiny leaves of this Thyme plant variety don’t have much flavor, it’s used as a predominately ornamental ground cover that produces purple color flowers. Some common varieties include ‘Doone Valley’ and ‘Albus’.
Lemon Thyme – This shrub-like Thyme plant is great for cooking and full of flavor. Some of the best varieties include ‘Aureus’, ‘Golden King’, and ‘Silver Queen’.
Caraway Thyme – Growing up to 5 inches tall and full of pretty pink flowers, this Thyme plant thrives in southern gardens.
Thymus citriodorus – This Thyme varietal grows closer to the ground, often resembling a mat or carpet once established. As its name implies, its bright yellow-green color leaves boast a distinctly lemony scent.
Thymus ‘Silver Queen’ – It is a compact and busy Thyme variety, and it is known for its greenish-gray leaves and rich red stems. It is used to edge pathways or fill cracks in stone patios.
Thymus herba barona – It is also known as caraway Thyme, this variety has a similar taste to its cousin herb and is native to Sardinia and Majorca. It is more vine-like in appearance, often creeping down the sides of plant beds or pots.
Soil Requirement for Growing Organic Thyme
Soil is the most important element when growing organic Thyme. If you choose to do so indoors or outdoors, choose a soil mixture that is dry and well-draining, as Thyme is mainly susceptible to root rot and overwatering. Sandy mixtures are your best bet if you select to use potting soil you have laying around, cut it with a bit of gritty sand or gravel to ensure water moves through the soil quickly. A pot with ample drainage is also important for growing Thyme, and those made of clay or terracotta can be beneficial in wicking away extra moisture from the soil. Thyme can thrive in a wide range of pH values ranging from 6.0 to 8.0. In the early spring season, you may fertilize with organic matter, like compost, but not much soil amendment is necessary. Thyme will grow well in fairly poor, even stony, soil.
Site Preparation and Light Requirements for Growing Organic Thyme
Thyme plant prefers full sun to light shade with plenty of organic compost or well-rotted animal manure. Thyme plants thrive in pots and will spread between pavers to soften stone walkways. Thyme is a well-known sun lover and preferring to be planted in a spot with access to full light nearly all day long. A bright windowsill that gets around 8 hours of sun a day is ideal.
Tips for Growing Organic Thyme
- Space Thyme plants about 12 to 24 inches apart in a sunny location with fertile, well-drained soil with a pH level of 6.0 to 8.0.
- For best results feed the plant regularly with water-soluble plant food.
- Keep soil moist and water the plant when the top inch of soil becomes dry.
- Once Thyme is established, harvest as needed.
- Keep planting beds weed-free. To keep the Thyme plant from becoming woody, prune plants back by one-third in spring and again after flowering in the summer season. Divide Thyme every 3 years so that they do not become woody.
- Prune Thyme plants for the first year and pinch off stem tips occasionally throughout the growing season. Stop pruning about a month before the first frost of the fall season. Cut back old stems by about 1/3 in the spring of the second season. Try not to cut off any fresh growth and keep an eye on creepers, which can quickly spread out beyond their preferred space. Cut them back to keep them contained.
- Keep the weeds under control. Weeds that compete for the nutrients in the soil are a bad idea for horizontal growing plants like Thyme, so keeping the weeds in check will help Thyme to thrive.
- Don’t over-fertilize your Thyme plant. Once they start to flourish, the Thyme plant doesn’t need much nutrition to thrive. A simple infusion of compost in the spring and fall seasons should be plenty.
- Cut your crop back each spring. It’s the best method to encourage bushy growth and tender stems rather than a scraggly, woody shrub.
How to Propagate Thyme Plants
Thyme plant can be propagated by seeds and vegetative by division of old plants or by cuttings or by the layering of side shoots in March or April. Thyme seeds are sown directly in rows or the Thyme seeds are sown in well-prepared nursery beds in good soil. About 3% solution of Panchagavya can be used to soak the seeds or cuttings for 20 minutes before planting. This treatment increases the seeds germination or rooting percentage of the cuttings. Good soil is preferred for nursery because the seedlings are small and remain inconspicuous for several weeks after the germination process.
Process of Growing Organic Thyme from Seeds
The Thyme plant can be grown from seed. But frequently people choose to avoid growing Thyme seeds because Thyme seeds are difficult to germinate and can take a long time to sprout. If you would like to grow Thyme from seeds, follow the below steps for growing Thyme seeds;
- Initially, scatter seeds over the soil in the container by planting Thyme seeds. Next, gently scatter soil over the seeds. Water thoroughly and cover with plastic wrap.
- After that, start Thyme seeds indoors, covering seeds lightly with soil and keeping moist until seedlings appear.
- Place the container in a warm location and seeds will germinate in 1 to 12 weeks.
- Nutrient requirements for Thyme plants are not heavy, so soil only receives a moderate amount of fertilizer. Apply an organic garden fertilizer and liquid seaweed several times throughout the growing season. Prune back to encourage compact growth.
- Fill a container with drainage holes with a rich but well-draining growing mix and then sprinkle the Thyme seeds on top. Cover the sprinkled Thyme seeds with 1-2 cm of potting mix and don’t cover it too deeply.
Planting Thyme from Divisions
Divide roots of older, established plants from mid-spring to the early summer season. Usually, a Thyme plant is planting from a division and it is easy to divide. In the spring or fall season, find a mature Thyme plant. After that, cut a smaller clump of Thyme from the main plant. Replant the mother plant and plant the division to grow the Thyme herb.
Propagating Thyme from Cuttings
To start a new plant, and then clip off a 3-inch section from the tip of a mature one and apply a rooting hormone to the exposed stem pieces. Within 6 weeks, roots start to form, at which point you can transfer the cutting into a small pot until it reaches transplanting size.
Cuttings are easy to root and use tip growth cuttings. After that, dip the ends of about 4 to 6-inch Thyme cuttings in liquid rooting hormone. Then, plant in organic potting mix or sand under fluorescent lights. Thyme cuttings will root in about 4 weeks.
Process of Planting Thyme
- Thyme plant thrives in full sun. If you are growing Thyme in pots, plant near a sunny window.
- In the early spring season, you may fertilize with organic matter such as compost, but not much soil amendment is necessary.
- It is hard to grow Thyme from seeds because of the slow germination process. It is easier to buy the Thyme plants from a garden center or take some cuttings.
- Plant Thyme cuttings any time after the ground temperature level reaches 21°C. Usually, this is 2 to 3 weeks before the last spring frost in well-drained soil about 9 inches apart.
- Depending upon the specific variety, space young plants about 12 to 24 inches apart. The plants should grow about 6 to 12 inches in height.
- Plant Thyme near cabbage or tomatoes in the garden. If you are growing Thyme in containers, plant with rosemary which likes sunny conditions.
- For Thyme plant growth, keep weeds under control during the growing season.
- Mulches also help retain soil moisture and maintain even soil temperature levels. For plant growth, an organic mulch of aged bark or shredded leaves lends a natural look to the bed and also improves the soil as it breaks down in time.
- Keep Thyme plants well-watered during the growing season. During the growing season, Thyme plants need about 1 inch of rain per week. By using a rain gauge to check to see if you need to add water. It’s best to water with a drip or trickle irrigation system that delivers water at low pressure at the soil level. If you water with overhead sprinklers, water the plant early in the day so the foliage has time to dry off before evening, to minimize disease problems. Keep the soil moist but not saturated.
- The lifespan of Thyme plants averages about 5 to 6 years. If you notice the Thyme plants are beginning to deteriorate, prune the existing plants back hard to rejuvenate them. Monitor for pests and diseases.
Watering and Mulching Requirements for Growing Organic Thyme
Once established, Thyme plants are drought-resistant and prefer to be under-watered rather than over-watered. It also requires plenty of water throughout the first season to help it get established enough to thrive. Once Thyme plant is established, it only needs to be watered when the soil below is completely dry. Pruning off dead and dying stems in the spring and fall seasons will help keep each plant healthy for the coming season. Thyme survives a rough winter and adds a thick layer of mulch to the plants to prevent them from freezing.
Companion Plants for Growing Organic Thyme
Plenty of garden plants do well with Thyme, but the rosemary plant is the perfect herb to pair with it because they both have the same watering needs. Also, you can plant Thyme next to Strawberries, Eggplant, Broccoli, and Cabbage for the benefit of all plant species.
Manures and fertilizers for Growing Organic Thyme
Application of well-decomposed FYM (farmyard manure) by 50 t/ha and biodynamic compost by 5 t/ha
Application of vermicompost by 5 t/ha
Application of Neem cake by 1.25 t/ha
Application of Azospirillum and Phosphobacterium by 25 kg/ha
Foliar spraying of Panchagavya, an organic preparation by 3% at monthly intervals should be done. Spraying panchagavya about 5 times a year will increase the yield and quality of the green leaves.
Problems in Growing Thyme Plants
Reasons for Thyme Dying
The most common reasons for Thyme dying are;
- It is drooping and turning yellow color because of excess nitrogen in the soil.
- Thyme plant that is turning brown color, dry, and dying back.
- Leaves growth slowing and foliage because of a lack of sun or nutrients.
- Drooping or slow-growing Thyme due to small pots or containers or a lack of drainage holes in the base of the pot or container.
- Thyme plant that requires reviving after winter.
Thyme Plants Turning Yellow and Wilting
Symptoms – The Thyme plant leaves are turning yellow often, with a wilting appearance.
Causes – Excess nitrogen because of fertilizers.
Thyme plants are mostly adapted to low to medium fertility sandy soil. If the soil is rich in nutrients or more perhaps there have been applications of fertilizer, there is likely a high concentration of nitrogen in the soil. Excess nitrogen causes the Thyme plant to grow leggy, droop or wilt and the aroma and flavor of the plant leaves are not as pronounced which has a big effect if you are growing the Thyme plant for culinary use.
Yellow foliage and wilting appearance are symptoms of root rot so ensure that you allow the soil to dry out between bouts of watering and then plant (or transplant) Thyme into well-draining soil.
Revive with Yellow Color Leaves – For applying fertilizer to Thyme then you must stop as this promotes excess foliage growth with a weaker aroma and flavor. Ideally, transfer the Thyme plant from garden soil or the pot to a new pot or area of the garden and then amend the soil with 30% sand to improve drainage and balance the soil nutrient profile.
Prune back the leggy or wilting growth of the Thyme plant to a rounded appearance (do not cut back into woody growth as this is not growing back particularly well). Yellow color leaves for most plants often indicate root rot, too much nitrogen, and even not enough nitrogen.
Thyme Plant not Growing
Symptoms – Thyme plant with no growth and an unhealthy appearance.
Causes – Thyme planted in a pot that is too small, lack of sunlight or competition from other plants for resources or plant that is more than 5 years old.
Thyme prefers to live in soils with low nutrients and little moisture so they do not naturally grow quickly although creeping Thyme does grow quickly with full sun. Though, if it is spring or summer and your Thyme is not growing and looking unhealthy then there is likely a problem with the growing conditions. Thyme plant can still grow after 4 years however the growth does naturally slow down and there may be some dieback, with some of the leaves turning brown color and dried up which is the natural life span of the plant.
A lack of sunlight can limit the overall growth and flavor of the Thyme leaves. Nearby plants can also compete for space, light airflow, nutrients, and water which can cause the Thyme plant to grow slowly or die. Pots and containers that are small naturally limit the space for the roots to develop which can cause your Thyme to not grow.
How to Revive Thyme Plants that are not Growing – Plant Thyme in a container or pot that is at least 12 inches across to ensure the roots of the plant have enough space to develop so the plant roots can access the moisture and nutrients it requires.
Always locate Thyme plants in full sun (at least 6 hours per day) so they can grow and then stay healthy. In more humid climates plant Thyme around 2 to 3 feet apart for best results. Thyme plants are not long-lived herbs and the growth can slow after 3 years and they can die after 4 or 5 years even with good care.
The smaller the pot that you plant your Thyme in, the less capacity there is for soil, nutrients, and root development. So, planting in a larger pot (at least 12 inches across) allows the roots enough space to establish properly which will promote growth.
Pests and Diseases Control in Growing Orgnaic Thyme
Spider mites can be a problem in dry weather conditions. Also, watch out for root rot and fungus diseases in humid climate conditions. Good drainage, good air circulation, and proper planting will help to prevent this disease.
Thyme is susceptible to botrytis rot, Rhizoctonia or root rot, and other plant diseases. Carefully select locations with good drainage and plenty of air circulation to prevent diseases.
Common insect pests attacking the Thyme plant include aphids and spider mites. Watch closely and follow some pest control methods;
- Remove weeds and garden debris to eliminate alternate hosts.
- Discard severely infested plants by securely bagging.
- Carefully release commercially available beneficial insects to attack and destroy insect pests.
- Spot treat pest problem areas by using diatomaceous earth, neem oil, or another organic pesticide.
Because Thyme usually does a good job of attracting beneficial insects, it doesn’t have several problems with harmful pests. The insects in Thyme plants are aphids and spider mites, but both can be kept away by using an organic insecticide. Allow Thyme bed’s soil to dry out completely before watering to avoid this problem.
When and How to Harvest Thyme
The Thyme leaves and flowers that are used for culinary and medicinal purposes are harvested 5 months after sowing/planting. The leaves and flowers are plucked from the plants about 15 cm are cut off from the plants, dried in shade or dryer after harvest, and then stored in airtight containers to prevent the loss of flavor.
Harvest Thyme plant just before the plant flowers by cutting off the top 5 to 6 inches of growth. Leave the tough, woody parts. Clean Thyme leaves should not be washed, because it removes some of the essential oils.
You can start to harvest Thyme within the first year through occasional cuttings. Thyme leaves are great in recipes when both fresh and dried but be sure to harvest plants in the early morning for peak flavor. Always leave at least 5 inches of each plant left to ensure it has enough stored energy to keep growing.
