Planting Herb Plants From Seed

Watering herbs

Herb plants are a popular type of plant to grow inside and outside.

If you have the itch to grow something and it’s not quite warm enough to plant herb plants outside, growing them from seed can be a good idea. 

We’ll cover some details on how to grow herb plants from seed and helpful information to keep in mind as your seeds germinate and grow into small herb plant plants.

Why plant herb plants from seed

There are a number of reasons you may want to grow your herb plants from seed. 

The first, and already mentioned, is time. If you’re in the winter months, purchasing small herb plants to grow may not be possible.

You can also save money, as herb plant seeds are a fraction of the price of purchasing young plants at a nursery or garden center.

Finally, it gives you a feeling of satisfaction to grow the herb plant from seed all the way through to the end of its lifecycle.

Varieties of herb plants you can start from seed

You can plant most herb plant varieties from seed. 

What temperature is ideal?

A herb plant seed requires a certain temperature range in order to germinate. Outside of this optimum range, germinating your herb plant seeds is still possible, but your success rate will be less.

Most plants’ ideal temperature range to germinate is 68 – 86 degrees Fahrenheit

When to sow the herb plant seeds

Choosing the best time to sow your herb plant seeds depends on when you are planning on planting them outside. 

Typically, herb plant seeds should be planted 6-8 weeks before you plant to plant them outside. Check your seed packet for the specific timing of your planting.

It’s definitely possible to plant herb plants outside of this window, but you may need to nurture the plant more inside before it’s warm enough to plant it outside. 

Knowing when to plant an annual outside can be tricky, so make sure it’s not too early in the season when you plant your herb plant outside.

How long will it take for herb plant seeds to germinate?

Your herb plant seeds should germinate 7-14 days after they are planted.

This timeframe may change depending on how consistently you are keeping the soil moist and in the light. A seed that isn’t well taken care of will take longer to germinate or die before ever sprouting.

How to plant herb plants from seed

To plant herb plants from seed, you can follow the following steps

1. Purchase the herb plant seeds & potting soil

This can be done at many garden centers or greenhouses. If seeds are not available this way, many online stores offer herb plant seeds for sale.

Your herb plant seeds will grow best in potting soil rather than topsoil, so make sure to purchase some potting soil to plant the seeds in.

2. Find a container to plant in

You’ll need a container for your soil and herb plant seed. Seeds do not need much space to grow. In fact, you can plant multiple seeds in the same container and then separate the sprouts once they germinated and plant them in their own spot.

For a home solution, egg cartons or egg trays can be a good place to plant seeds and have them sprout. These containers provide more than enough room for a seed to germinate.

3. Plant your herb plant seeds

To plant the herb plant seeds, fill your container with potting soil. No need to fill it to the brim, as water runoff may overflow the container.

Now it’s time to plant your seed. The general rule of thumb with seeds is to plant them 2 to 3 times their length. You’ll want to error on the side of not planting them deep enough.

To plant the seed, you can poke a hole in the potting soil with your finger, or use a stick.

Cover the seed up with potting soil once you have placed the herb plant seed in the hole.

4. Water your newly planted herb plant seed

Water the herb plant lightly. Be careful not to overwater it. A herb plant seed only needs damp soil to begin its germination.

Transplanting herb plant seedlings

After the herb plant seed has sprouted, you can transplant it into another container.

To do this, push your finger down below the sprout and gently pull up so that minimal roots are damaged.

Once you have a free herb plant sprout, you can plant it in another container and gently water it in.
