When To Plant Cilantro In Oklahoma

The best time to plant cilantro in Oklahoma is early spring, from late March through April.
 
Cilantro loves cool weather, and Oklahoma’s spring gives it just enough chill before the heat cranks up.
 
If you’ve been wondering when to plant cilantro in Oklahoma, the answer really depends on how fast summer arrives in your part of the state.
 
You can also plant cilantro in Oklahoma in late summer for a fall harvest, usually around late August to mid-September.
 
Because cilantro bolts quickly once temperatures climb, timing is everything when you plant cilantro in Oklahoma.
 
In this post, we’ll look at the best windows for planting cilantro in Oklahoma, how to work around Oklahoma’s crazy weather, and a few tricks to keep your cilantro producing longer.
 
Let’s dig in.
 

When to Plant Cilantro in Oklahoma

When you plant cilantro in Oklahoma, you’re really racing against the heat.
 
Cilantro is a cool-season herb, so it grows best when daytime temps stay between 50°F and 75°F.
 
Once Oklahoma hits the 80s and 90s, cilantro shifts gears and bolts, sending up a flower stalk instead of those tasty leaves.
 
That’s why knowing when to plant cilantro in Oklahoma matters so much.
 
Here are the main planting windows that work well across the state:
 

1. Early Spring Planting

The most popular time to plant cilantro in Oklahoma is early spring.
 
For most of the state, that means sowing seeds directly in the garden from late March through mid-April.
 
In southern Oklahoma, you can sometimes plant cilantro in Oklahoma as early as mid-March.
 
In northern areas near Tulsa or the Panhandle, waiting until early April is safer since late frosts can still sneak in.
 
Cilantro seeds germinate best when soil temperatures are around 55°F to 68°F.
 
If you plant cilantro in Oklahoma too early, cold snaps can slow germination, but the plants usually pull through fine.
 

2. Succession Planting Every 2–3 Weeks

One planting won’t cut it if you want cilantro all season in Oklahoma.
 
Smart gardeners plant cilantro in Oklahoma in small batches every two to three weeks during spring.
 
This way, when one patch starts bolting, the next one is just hitting its prime.
 
You can keep this up until about mid-May, when the heat makes germination and leaf growth tough.
 
After that, cilantro in Oklahoma tends to bolt within weeks, so succession planting buys you extra harvest time.
 

3. Fall Planting for a Second Chance

If spring slipped past you, don’t worry, you can still plant cilantro in Oklahoma in late summer.
 
Around late August to mid-September, soil and air temps start dropping enough for cilantro to thrive again.
 
Plant cilantro in Oklahoma at this time and you’ll often get a longer harvest than spring, sometimes clear into November.
 
In fact, many Oklahoma gardeners say fall cilantro is easier because pest pressure drops and the weather cooperates longer.
 
Just make sure to water consistently, since late summer in Oklahoma can still serve up some scorchers.
 

4. Overwintering in Southern Oklahoma

In southern parts of the state, cilantro can sometimes overwinter if you plant it in fall.
 
A mild winter means cilantro might survive and start growing again in early spring.
 
If you plant cilantro in Oklahoma in a sheltered spot with good drainage, you may get volunteers popping up the following year.
 
That said, most Oklahoma winters get cold enough to kill cilantro, so treat it as an annual unless you’re in a warm microclimate.
 

How to Plant Cilantro in Oklahoma for Best Results

Knowing when to plant cilantro in Oklahoma is half the battle, but how you plant it matters too.
 
Cilantro has a taproot, so it hates being transplanted.
 
Direct sowing is almost always the better choice when you plant cilantro in Oklahoma.
 
Pick a spot that gets morning sun and some afternoon shade, especially as spring turns warmer.
 
Work the soil loose and mix in compost so the taproot can stretch down without fighting compacted Oklahoma clay.
 
Sow seeds about a quarter inch deep and keep the soil moist until they sprout, usually in 7 to 10 days.
 
You can also soak seeds overnight or lightly crush them to speed up germination.
 
Once seedlings are a couple inches tall, thin them to about 6 inches apart so air can move between plants.
 
Water regularly but don’t drown them, since cilantro in Oklahoma can rot if the soil stays soggy.
 
A layer of mulch helps keep soil cool, which slows bolting when you plant cilantro in Oklahoma.
 

Tips to Keep Cilantro from Bolting in Oklahoma

Oklahoma heat is cilantro’s worst enemy, but you can outsmart it.
 
Choose slow-bolting varieties like ‘Santo’ or ‘Long Standing’ when you plant cilantro in Oklahoma.
 
Give plants afternoon shade, especially in June and July.
 
Harvest leaves often, starting from the outside, to keep the plant focused on leaf growth.
 
Once you see flower buds, pinch them off right away to delay bolting.
 
If bolting happens anyway, let some flowers bloom, since the seeds (coriander) are edible and bees love them.
 
You can also grow cilantro in containers so you can move them out of the harsh afternoon sun.
 

So, When to Plant Cilantro in Oklahoma?

The best time to plant cilantro in Oklahoma is early spring, from late March through April, with a second window in late August to mid-September for a fall crop.
 
Cilantro thrives in cool weather, so timing your planting around Oklahoma’s heat is the key to a steady harvest.
 
Plant cilantro in Oklahoma in succession every few weeks, give it some afternoon shade, and harvest often to keep it from bolting.
 
Whether you’re in Tulsa, Oklahoma City, or somewhere in between, you now know exactly when to plant cilantro in Oklahoma for the best results.
