How much sun does Thyme need? 

All plants need sunlight to continue the process of photosynthesis. However, different plants require different light conditions to thrive, and Thyme does best in full sun.  

The best location for Thyme is on a sunny windowsill that gets around eight hours of sunlight each day, but if your home is mainly shaded or you want to keep it alive through the gloomier winter months, a cozy area beneath some fluorescent grow lights will do. Grow lights can also help you to provide the warmth that your plant needs. 

The best location and temperatures for Thyme

This plant prospers more in dry and hotter conditions. So try as much as possible, and aim to keep your indoor plant area temperature between 60 and 80 degrees Fahrenheit while taking precautions to keep humidity levels as low as possible.

How much water does Thyme need? 

Once you plant the Thyme, you must wait until the soil dries out before you water it. Thyme is native to hot climates and prefers to dry out between waterings. Keeping the soil too wet can harm your plant. 

After some time and adequate watering, your Thyme will start to have flowers, but unlike other herbs, this does not indicate overwatering. If you cut it back to encourage new growth, it will continue to thrive after flowering.

What are the best pots to grow Thyme indoors? 

Your main goal is to grow this plant indoors, so you need the right plant pots and planters! And some essentials for your garden are necessary to maintain your indoor gardening efforts. 

Thyme grows well in small pots that you can place on a windowsill or hang the plants with plant hangers to add visual interest. 

The best containers to grow Thyme in are unglazed clay (terracotta) pots with good drainage. The clay is porous, so it helps the soil dry out between waterings. Containers should also be the right size and more on the shallow end of the spectrum to avoid waterlogged soil.

How to Care for Your Thyme Plants

Feeding and Fertilizing Thyme Plants

Usually, growing Thyme indoors and in small pots, you don’t need many add-ons as the nutrients in the soil will remain there for some time. However, over time, the plant will use up the nutrients, and others will be lost during watering and draining. 

If you want to keep your Thyme healthy boost it’s growth, you need to be proactive and target its growing season, fertilizing it with diluted liquid fertilizer. 

Additionally, ensure that you add just the right amount of fertilizer to benefit rather than harm your Thyme plants, as concentrated chemical fertilizers can burn the plant. 

We recommend organic liquid fertilizers, diluted so that there is no risk to the plant or to the people eating it. 

When to Split and Prune Thyme 

As a perennial, Thyme should be pruned in early spring, just before the weather warms up, as it will grow through the spring and summer months. 

Cut the woody stems right back. This is also a good time to divide and re-pot larger Thyme plants. You can split your plants into sections (each with an intact root system) and replant them into smaller pots. A well-draining potting mix is best, and make sure your pots have good drainage.

Indoor-Specific Pests and Diseases

When growing Thyme indoors, there are only a few pests and illnesses you need to be concerned about. Gnats, white flies, and mealy bugs are the pests that affect these plants most frequently.

Your plant will be surrounded by whiteflies that resemble tiny moths. Additionally, they will suck the sap from your Thyme leaves.

Keep an eye out for potential threats to your herb, and you’ll have a better chance of spotting problems early and sparing your plant needless damage.

Thyme does not do well in damp, humid conditions and may develop fungus or mold on the leaves and stems. Overwatering and having waterlogged soil in your post can lead to root rot, which can be fatal for your plant. 

As with most things, prevention is key! Keep your plants in dry, well-ventilated conditions to avoid fungus and mold, use appropriate containers and let the soil dry out thoroughly between watering to avoid root rot, and keep your plant away from new plants until you see that they have not brought any bugs in with them. 

If you have pests, you can use a Neem oil solution or buy pesticide sprays. However, we recommend avoiding pesticides on plants that will be used in the kitchen and prefer to use organic and eco-friendly pest control methods

When to Harvest Thyme

Once grown, potted Thyme plants can be harvested whenever you’d like, just like outside plants. Harvest your Thyme by pinching off the stems, leaving about 1/3 of the stem behind. This will give you the majority of the leaves on the stem, leave some leaves behind, and stimulate new growth.

You can use your Thyme fresh or hang it somewhere cool and well-ventilated to dry out. You can keep dried Thyme for months and use it as and when you need it. Thyme can also be infused into oils for cooking or salad dressings, or distilled to make an essential oil.
