Tips For Growing Tarragon Indoors

by johnah on November 17, 2020

Terrific! I am glad to see that you have read through all the information and are now ready to grow your own tarragon indoors. You will be happy with the results when you plant it out again. Now let’s get started…

1) Choose Your Location:

The first thing you need to do is choose where you want to put up your new indoor garden. If you live in a warmer climate, then you might want to move the plants outdoors.

You could even start them indoors right away if they are just starting to flower. However, if you live in a cooler climate, then it may not be necessary at all.


How Much Space Do You Need?

You need enough space so that there is plenty of room for the roots of each plant and for any other items that may be needed inside such as soil or fertilizer. Also, you need room for the heaters that will keep the plants warm during winter months.


What Kind Of Lighting Will You Use?

If you plan to use fluorescent bulbs, then make sure that they are not too bright since they will burn your eyes. If you don’t mind using incandescent lights, then go ahead and do it. Just remember to turn off your lights before going to bed.

Also, you can choose from either cool or warm light bulbs. The cool light bulbs are usually used for flowering plants and the warm light bulbs are usually used for vegetative growth.


What Kind Of Soil Will You Use?

If you plan on using regular soil to grow your tarragon then it must be sterilized before use because it probably contains various types of fungi and bacteria that will kill your plants. You can use either sand, vermiculite or perlite to sterilize the soil by baking it in the oven at a temperature of 230 degrees for about 30 minutes. Remember to let it cool completely before use. Of course if you are really concerned with your plants then you should use a soilless medium that has been sterilized instead.


What Kind Of Nutrients Will You Use?

For regular houseplants, the best kind of nutrients to use are the time-released type. However, if you want to give your plants a Vitamin-B shot every now and then, then using a soluble type is fine too.


Where Will The Soil Go?

The best place to put your soil is in some sort of a tray. This will allow you to easily water your plants as the water will drain out from the bottom. You can also use containers such as buckets or garbage cans, but you will have to dump out all the water every couple of days so it doesn’t stagnate and become a breeding ground for harmful bacteria.

What Kind Of Equipment Do You Have?

If you have everything from the list above, then you are ready to start building up your own indoor garden. If not, then you may need to make a trip to the hardware store before you get started. Don’t worry; this is perfectly normal.


What Is The Right Temperature?

The temperature that you grow your plants at will depend on what kind of lighting you use. You can use the table below to give you an idea of what temperatures will be best based on your lighting. If necessary, use a heating pad to keep things warm and/or a cooler with ice packs to keep things cool.

Lighting Temperature

Incandescent/Natural Light (Cool Light) 60-70 degrees F

Fluorescent (Cool White) 60-70 degrees F

Fluorescent (Daylight) 70-80 degrees F

Fluorescent (Gro-Lux) 80-90 degrees F

Cool White = 4500K

Daylight = 6000K

Gro-Lux = People usually use blue filters with these bulbs.


What Kind Of Schedule Should You Follow?

If this is your first time growing, then you should probably start out by mimicking the sun’s natural lighting pattern. This means that you should place your plants within a few feet of a window (with the curtains open) for a few hours each day. Make sure that you don’t place the plants too close to the window as this could possibly burn the leaves.

The best thing to do is to use an outdoor yardstick and measure the distance from the window to the plant. Use this measurement each day that you place your plants by the window.

This way, you will know for sure that your plants are always getting the same amount of light each day.

After a few weeks, you should see little “leaves” starting to form on the top of your plants. This means that it is time to start 12 hours of light and 12 hours of complete darkness each day.

You can achieve this by using a timer or you could just turn the lights on and off each day yourself. Remember that the dark period must be COMPLETE darkness or your plants will not get the right amount of Light to grow healthy. If you still have questions on this topic, ask us at the GrowFAQ Forum.

Also do not be discouraged if your plants appear to “die” or show signs of wilt for the first week or so. This is normal with new plantings as they are adjusting to their new atmosphere.

Remember that light plays an extremely important role in plant growth, but SO DOES FOOD! If you are growing in a “soil” that is not food for the plant, then all your light in the world isn’t going to help you.

We suggest reading our Plant Food Deficiency Symptoms page to see if you are providing for all of your plants needs.


What Is This Plant Food That You Speak Of?

Plants need a lot of different kinds of nutrients in order to grow big and strong.
