The word “thyme” comes from the Greek word “thumus,” which means “courage.” In the Middle Ages, knights wore thyme sprigs on their armour to show they were brave. In this blog, we’ll talk about everything you need to know for growing thyme indoors, including the basics, what you’ll need, how to set it up, how to grow it, how to care for it, and how to pick it.

Can thyme be grown inside? 

When it comes to herbs, thyme is one of the easiest ones to grow. The hardest thing about growing thyme indoors is making sure the plant gets bright light all the time. Besides that, thyme is easy to take care of. It likes average quality soil, average amounts of water, and average temperatures, which makes it a great herb for beginners to grow indoors.

(a) Using soil for growing thyme indoors 

  • It’s pretty easy to grow thyme indoors, but remember that they don’t do well in wet soil. The roots are not used to being too wet, so they will rot if it gets too wet.
  • On the other hand, if the soil dries out completely, the roots will die back, and the plant won’t get better.This can catch you off guard because the plant isn’t very expressive (its leaves don’t wilt), so it will look fine right up until it dies.

(b) Using hydroponics for growing thyme indoors 

Thyme doesn’t do as well as other herbs in hydroponic systems like the aero garden. It is because it prefers drier environments.

(1) Care for Growing Thyme Indoors

(a) Sunlight

  • Thyme is well-known as a plant that likes to be in the sun. It grows best when planted or put in a spot where it can get full sunlight for almost the whole day.
  • The ideal is a windowsill that gets six-eight hours of sun a day, but if your home is mostly shaded or you want to keep your thyme growing through the darker winter months, a cosy spot under some fluorescent grow lights will also work. 

(b) Soil

  • The soil may be the most important thing if you want to grow thyme successfully. Choose a soil mixture that is very dry and drains well since thyme is especially prone to root rot and dying from too much water. 
  • The best choices are sandy mixtures. If you want to use potting soil you already have at home, mix it with a bit of sand or gravel to help water move quickly through the soil. 
  • It’s also important to use a pot with good drainage for growing thyme indoors. Pots made of clay or terracotta can help pull extra water out of the soil. Thyme doesn’t care too much about the pH level of the soil. It can grow well in a wide range of pH levels, from 6.0 to 8.0.

(c) Watering

  • Once established, thyme plants can handle drought and often do better with less water than with too much. Please wait until your thyme plant’s soil is completely dry, then give it a lot of water.
  • Let the soil dry out again before you give it more water. Remember that thyme will flower, but unlike other herbs, this doesn’t mean it’s getting too much water or going to seed.
  • If you cut it back to encourage new growth, it will continue to grow and thrive even after it blooms. 

(d) Fertilizer

  •  Thyme grows best in soil that is low in nutrients, so you don’t need to add extra fertilizer. It also means that it’s best to plant the herb by itself in a pot or container since mixing it with other herbs might make the soil too rich for it to grow well. 
  • If you want to give your thyme a boost:Feed it a diluted liquid fertilizer at the beginning of its growing season.
  • Choose an organic fertilizer if you plan to cook with or eat your herb.Pay close attention to the fertilizer package to ensure you add just enough to help your thyme plants and not hurt them. 

(e) Temperature

  • Thyme comes from the Mediterranean and does best in a dry, hot climate. Try to keep the temperature in your home between 60 and 80 degrees Fahrenheit for effectively growing thyme indoors.
  • Ensure there isn’t too much humidity (that means keeping your plant away from rooms that tend to be more humid, like kitchens or bathrooms). 

(f) Trimming

  • Once established, indoor thyme plants can be picked at any time, just like plants that grow outside. Just cut the stems off when you need the herb for a recipe. 
  • After three or four years, potted plants can get woody, at which point you should take them out, break them apart, and replant the smaller pieces in separate pots with fresh potting mix. 

(g) Size of Container

  • Thyme doesn’t need much space to grow, so you can use even a small pot with a diameter of four inches to grow young plants.
  • This plant might do best in clay or terracotta pots. Make sure there is good drainage in the container for growing thyme indoors.

(2) Planting and Repotting Thyme

  • When a thyme plant grows woody stems instead of soft leaves and shoots, it’s time to move the plant to a new pot. Carefully take it out of its pot and cut the root into pieces.
  • Select the smaller pieces to move into new pots. Choose a small pot that is about 4 inches across. Put the plants back in their pots with the right potting soil mix, as explained above. 
  • Thyme is being moved outside for the summer. 
  • Thyme grows best in full sun and is a great plant to grow outside. Move the pot outside when the temperature stays above 60 degrees Fahrenheit and is pleasant most of the time.
