Spring is here and the warmer temperature is a great time to start thinking about growing herbs. Luckily, it is super easy to grow herbs indoors and you will have great tasting meals with a fresh herb or two because of your indoor herb garden.
Some of the easiest herbs to grow are basil, mint, parsley, rosemary, and thyme. And what’s great is they can easily be grown in a container garden indoors.
How to start growing herbs indoors
I walked over to my local Whole Foods to buy seeds but you can easily get them at garden centers, Home Depot, and other plant shops. The basil I’m growing actually came from a basil growing kit I got from Dollar Tree.
If you do not have all the things needed like pots and soil there are a ton of herb growing kits. These are some of our favorites from Amazon:
What do you need to grow herbs indoors?
- Seeds – Think about what you buy from the grocery like basil, cilantro, parsley, or whatever herbs you usually use while cooking
- Seed starting mix, potting soil, or potting mix that you make yourself
- Small plant pots (these are so cute)
- Plastic dome with seed tray or plastic wrap
- Water sprayer
- Grow light
How to grow herbs from seeds indoors
First off, read the seed packet to learn more about the needs of the specific herb – when to plant, the right temperature, how far apart the seeds should be, etc.

One of the easiest ways to start seeds is in a plastic bag. It acts like a mini grow tent, plus you do not have to plant the seeds that will not sprout.

Simply moisten two paper towels, place seeds between them, and seal in a sandwich bag. Once they have sprouted, carefully peel away the paper and plant in pots with potting soil.
How to start herbs in pots
- Prepare the soil or seed starting and mix with water. It should be damp.
- Add the potting medium to the pots and fill up 3/4 to the top. You can add more seeds than recommended because not all the seeds will sprout.
- Cover the seeds with more potting medium and gently pat it down.
- The seeds need humidity with the soil moist, so it’s best to cover the pots individually, cover each pot with plastic wrap or place it in a seed tray and cover it with a dome.
- Keep covered until the seeds start to germinate then remove the plastic wrap or the plastic dome.
- Place the seedlings under a grow light
- When the seedlings have true leaves you can transplant them into individual pots.

The different types of soil used when growing herbs from seed
Not all growing mediums are created equal! You have to think about what the seeds need to germinate well.
- Seed starting mix is specially made for germinating plants, it has a fine texture that will be good for the delicate roots of the seedlings
- Potting soil or potting mix is best for when the seedlings are transplanted into bigger pots, it typically has fertilizer and perlite mixed in
- Never use plain old dirt from the ground, it is not suitable for herbs
Though you can definitely start seeds in potting soil or mix if that is what you have. No need to stress over that! I made my own potting mix with vermiculite, perlite, and worm castings.
Growing herbs from seed – watering tips
Water whenever the soil on top looks dry but the pot should never dry out. In the same line, the soil shouldn’t be super wet either. You will probably have to water once a week if the weather isn’t too hot. It’s also a good idea to water and let it drain out once a month to flush out any buildup.
As much as possible try to avoid getting the leaves wet when watering. Water it around the base and on the soil. It will help avoid mildew and disease.

What to expect next?
The seedlings will become big enough for transplanting into bigger pots in one to two months. I have transplanted three to four seedlings into pots with no problems. I just keep in mind that I might have to eventually repot again to a bigger pot.
There may come a point when you have to stake the herbs of your indoor garden. You can use chopsticks easily and twist ties. But you should really be pruning and harvesting the herb plants regularly to keep the plants healthy.

Herb Maturity Estimator
As with any indoor plant, herbs can be grown if they have the right conditions. I think in the case of herbs, it’s the right light that is important. And it doesn’t have to be sunlight, herb plants will be happy under a grow light! And you will be rewarded with fresh herbs to add to your salad, pasta sauce, or mojito. That’s a great way to enjoy your indoor garden!
when is the best time to plant herbs indoors?
The best time to start is in March but the seeds can be started anytime between March and August.
what is the right herb growing temperature?
Your best bet is to keep them in a room with 60-75 degrees. Some herbs cannot withstand lower temperatures, even if they are indoors.
what are some of the fastest-growing herbs?
Most herbs that we use are good growers – mint, cilantro, basil, parsley, green onion, dill, and chives.
which herbs need light to germinate?
Thyme needs light to germinate. Other herbs like basil, parsley, mint, oregano, and coriander can be in a slightly dark area to germinate. But all herbs will need bright light to thrive.
do herb plants need fertilizer?
Indoor herb plants will need a boost from fertilizer. To avoid over-fertilization, do it every two months or so.
