Cilantro ‘Slow Bolt’ is well adapted to tolerate partially shaded and full sun areas of the garden and can tolerate cooler temperatures and a light frost. Cilantro is grown primarily for its broad, deep green and pungent edible foliage. This variety does well in containers and does not require much effort to maintain, making it a good choice for new gardeners. Since Cilantro has a such quick life cycle, you’ll want to be sure to have enough seed on hand to reseed succession plantings every two weeks. When temperatures get hot, cilantro will begin to bolt, at which time reseeding is recommended for best flavor. This variety has been bred to be less susceptible to premature bolting, hence the name ‘slow bolt’. This seed can also be used for growing microgreens.
In North America the stalks and the leaves of the Cilantro plant are known as cilantro and the plant’s dried seeds known as coriander. However, in some parts of the world the plant is called coriander and the seeds called coriander seeds. No matter what you call it, cilantro is a staple in many Spanish, Mexican & Asian foods and has grown a reputation for either loving it or hating it. If you are a cilantro lover, try making your own home-grown salsa with fresh cilantro, Beefsteak Tomatoes, and green or red Jalapeno Peppers. If you are a cilantro hater, replace cilantro with Flat Leaf Parsley for a similar fresh-green & herbal taste with out cilantro’s pungency.

Starting Slow Bolt Cilantro seeds indoors is not recommended due to their long taproot.
If you choose to start these seeds indoors anyway, use biodegradable pots or containers to minimize root disturbance during transplanting.
Fill the pots with well-draining potting mix and moisten the soil and sow the seeds directly onto the soil surface, pressing them lightly into the soil. Water gently to settle the seeds in place.
Place the pots in a location with plenty of sunlight or under grow lights. Keep the soil consistently moist but not waterlogged.
Transplant the seedlings outdoors once they have developed at least two sets of true leaves, being careful not to disturb the roots.
Direct sow the seeds 1/2 inch deep, 4 inches apart and in rows spaced 18 to 20 inches apart.
Although Cilantro is possible to grow in containers and large pots, it prefers to be grown in the ground since it has a long taproot.
Germination usually takes 14 to 20 days; make sure your soil bed is consistently moist for best germination results.
Thin the seedlings to 8 to 12 inches apart as soon as they develop leaves.
For a continuous harvest, plant a new crop every 2 to 3 weeks.
You may begin to harvest once plants get to be 6 inches or taller.
Cilantro thrives in rich, well-drained soil and full sun but can also tolerate lightly shaded areas.
For the best tasting Cilantro, it is recommended to sow seed in early spring and again in early fall.
If planting in the summer, shade cloth may be required to keep it cooler and prevent bolting.
Cilantro does not tolerate transplanting very well, so indoor sowing is not recommended.
Keep the plants well-watered and control the surrounding weeds.
Cilantro can survive some light frost but does not tolerate temperatures above 75 °F for very long, as those temperatures will cause it to flower and produce leaves that have a very bitter taste.
Harvest Slow Bolt Cilantro leaves as needed once the plants have reached a height of about 6-8 inches.
Snip off the outer leaves near the base of the plant, leaving the inner leaves to continue growing.
Use fresh cilantro leaves immediately, as they lose flavor quickly after harvesting.
For extended harvest, sow seeds successively every few weeks throughout the growing season.
