You can keep cilantro growing indoors by giving it the right balance of light, water, and cool temperatures.
Cilantro is one of those herbs that grows quickly and tastes best when it’s fresh from your own windowsill.
If you’ve been wondering how to keep cilantro growing indoors without it bolting or turning yellow, you’re in the right place.
The good news is that cilantro grows well indoors as long as you mimic the cool, sunny conditions it loves outdoors.
In this post, we’ll walk through how to keep cilantro growing indoors, from choosing the right pot to harvesting your leaves.
Let’s dig in.
How to Keep Cilantro Growing Indoors Successfully
Keeping cilantro growing indoors comes down to a few key factors, and once you nail them, your plant will thrive.
Here’s what you need to get right.
1. Start With the Right Pot and Soil
To keep cilantro growing indoors, start with a pot that’s at least 8 to 10 inches deep.
Cilantro has a long taproot, so shallow containers will stunt its growth fast.
Make sure your pot has drainage holes because cilantro hates sitting in soggy soil.
Use a light, well-draining potting mix rather than heavy garden soil.
A mix with peat or coco coir works great for keeping cilantro growing indoors.
2. Give It Plenty of Bright Light
Cilantro needs at least 4 to 6 hours of bright light each day to keep growing indoors.
A sunny south-facing window is ideal, but if that’s not available, a grow light will do the trick.
Keep your grow light about 6 inches above the plant and leave it on for 12 to 14 hours daily.
Without enough light, cilantro growing indoors will stretch, get leggy, and produce fewer leaves.
So if you want to keep cilantro growing indoors, light is non-negotiable.
3. Keep Temperatures Cool
One reason cilantro is tricky indoors is that it prefers cooler temperatures than most homes offer.
The ideal range for cilantro growing indoors is between 60°F and 70°F.
When it gets too warm, cilantro bolts, meaning it shoots up a flower stalk and stops producing tasty leaves.
Keep your plant away from heating vents, radiators, and warm appliances.
If your home runs warm, a cooler spot near a window can help you keep cilantro growing indoors longer.
4. Water Consistently but Don’t Overdo It
Cilantro likes evenly moist soil, not wet feet.
Check the top inch of soil and water when it feels dry to the touch.
Overwatering is one of the fastest ways to kill cilantro growing indoors because it leads to root rot.
Underwatering, on the other hand, makes the leaves tough and bitter.
So aim for consistency when keeping cilantro growing indoors.
5. Fertilize Lightly
Cilantro isn’t a heavy feeder, but a little nutrition helps it keep producing leaves indoors.
Feed your plant every 3 to 4 weeks with a diluted liquid fertilizer.
Don’t over-fertilize cilantro growing indoors, as too much nitrogen can cause more leaf growth but weaker flavor.
A balanced, half-strength dose is plenty to keep cilantro growing indoors happily.
Common Problems When Growing Cilantro Indoors
Even with good care, a few issues can pop up when you keep cilantro growing indoors.
Here’s how to spot and fix them.
1. Bolting
If your cilantro growing indoors starts growing tall with lacy flowers, it’s bolting.
This happens when the plant gets too warm or stressed.
To slow it down, move the plant somewhere cooler and harvest leaves regularly.
Once cilantro bolts, the leaves turn bitter, so catching it early matters.
2. Yellowing Leaves
Yellow leaves on cilantro growing indoors usually mean too much water or not enough light.
Check your drainage and move the plant closer to a light source.
If the soil stays soggy, let it dry out before watering again.
3. Leggy Growth
When cilantro growing indoors doesn’t get enough light, it stretches toward the nearest window.
The stems get thin and weak, and leaf production drops.
A grow light fixes this quickly and keeps cilantro growing indoors compact and bushy.
Harvesting Cilantro Growing Indoors
The best part of keeping cilantro growing indoors is having fresh leaves whenever you need them.
Snip the outer stems first, about an inch above the soil line.
Never take more than a third of the plant at once so it can keep growing indoors.
Regular harvesting actually encourages more leaf growth.
And if you want a steady supply, sow new seeds every 2 to 3 weeks.
That way, you’ll always have cilantro growing indoors ready to use.
So, How Do You Keep Cilantro Growing Indoors?
You keep cilantro growing indoors by giving it bright light, cool temperatures, consistent watering, and light feeding.
Cilantro grows fast, so with the right setup, you’ll be snipping fresh leaves within weeks.
Just remember to harvest often, watch for bolting, and replant every few weeks for a continuous supply.
With a little patience, keeping cilantro growing indoors becomes second nature.
Enjoy your fresh, homegrown cilantro.
