You can plant cilantro in August, and it’s actually a great time to do it in many climates.
As summer heat starts to fade in late August, cilantro gets a second wind and produces tender, flavorful leaves instead of bolting too fast.
If you’ve been asking yourself “can you plant cilantro in August,” the short answer is yes, and the timing can work beautifully if you play it smart.
In this post, we’ll look at why August works for planting cilantro, how to plant cilantro in August the right way, and what to do so your crop thrives.
Why You Can Plant Cilantro in August
You can plant cilantro in August for several solid reasons, and understanding them helps you get the timing right.
1. Cilantro Loves Cooler Weather
Cilantro is a cool-season herb that grows best when temperatures sit between 50°F and 85°F.
August planting sets your cilantro up to mature in the cooler days of early fall, which is when it’s happiest.
2. The Late Summer Heat Starts to Ease
By mid to late August, the brutal heat of July is usually winding down.
This means if you plant cilantro in August, the seedlings won’t bolt as fast as they would in the peak of summer.
3. Fewer Pests Are Active
Many of the pests that hammer cilantro in spring and early summer are less active by late August.
So planting cilantro in August often means fewer aphids and less leaf damage overall.
How to Plant Cilantro in August the Right Way
If you want your August cilantro planting to succeed, you need to give it a little extra care.
1. Pick the Right Spot
Cilantro likes partial shade, especially when you plant it in August while some heat lingers.
A spot that gets morning sun and afternoon shade keeps the soil cooler and slows bolting.
2. Sow Seeds Directly
Cilantro doesn’t transplant well because of its taproot, so direct sowing is the way to go.
Scatter seeds about a quarter inch deep and keep them about 6 to 8 inches apart so they have room to grow.
3. Keep the Soil Consistently Moist
When you plant cilantro in August, watering becomes your number one job.
The soil should stay moist but never soggy, so check it every day during hot spells.
4. Sow in Succession
Cilantro bolts quickly, so planting cilantro in August works best if you sow a new batch every two to three weeks.
That way you always have fresh leaves coming instead of one big harvest that goes to seed.
5. Mulch to Cool the Soil
A light layer of mulch helps hold moisture and keeps the root zone cooler.
This simple step makes a real difference when you plant cilantro in August and the sun is still strong.
Challenges When You Plant Cilantro in August
Planting cilantro in August isn’t without its headaches, so it pays to know what you’re up against.
1. Bolting Is Still a Risk
If a heat wave hits, cilantro will shoot up a flower stalk fast.
You can slow this by giving shade and harvesting often, but you can’t stop it completely.
2. Uneven Germination
Cilantro seeds can be slow and spotty to sprout, especially in warm soil.
Soaking the seeds overnight before you plant cilantro in August can boost your germination rate.
3. Short Window Before Frost
In colder zones, August planting leaves only a couple of months before the first frost.
That’s still plenty of time for a harvest, but you may need a row cover if cold comes early.
Tips to Keep Your August Cilantro Thriving
A few smart habits make all the difference when you plant cilantro in August.
1. Harvest Often
Snip the outer leaves regularly to encourage new growth and delay bolting.
The more you pick, the longer your cilantro keeps producing.
2. Water in the Morning
Morning watering gives the plant time to absorb moisture before the heat sets in.
It also cuts down on disease compared to evening watering.
3. Feed Lightly
Cilantro doesn’t need heavy feeding, but a mild nitrogen boost helps after you plant cilantro in August.
Too much fertilizer makes leafy growth at the expense of flavor, so go easy.
4. Watch for Pests
Keep an eye out for aphids and whiteflies, which can show up in late summer.
A strong spray of water usually knocks them off without any chemicals.
So, Can You Plant Cilantro in August?
You can plant cilantro in August, and it’s often one of the best times to get a fresh crop.
The cooler weather, fewer pests, and fast growth make August planting a smart move for most gardeners.
Just give your cilantro shade, steady moisture, and regular harvests, and you’ll be rewarded with tender leaves well into fall.
So go ahead and plant cilantro in August and enjoy the fresh flavor it brings to your kitchen.
