Cilantro (\(Coriandrum sativum\)) is a popular annual herb, cherished globally for its bright, distinctive flavor in various cuisines. It is a fast-growing plant whose delicate leaves are often sought after by home cooks and gardeners. When the plant begins to “bolt” (produce flowers), many seek alternative propagation methods beyond traditional seed sowing to maintain a continuous supply. Propagating this herb using stem pieces is a common method for quickly expanding an herb garden.
Is Cilantro Propagation From Cuttings Viable?
Propagating cilantro from stem cuttings is possible and provides a convenient way to start new plants quickly, though it is not the primary commercial method. While seeds offer a more reliable and vigorous foundation, rooting healthy stems bypasses the 40 to 70 days required for seeds to reach a harvestable size. This technique is useful for utilizing fresh cilantro purchased from a grocery store.
Successful rooting depends on selecting the right material and timing the cutting. The best cuttings come from non-flowering, healthy stems, ideally three to five inches long. Stems that have begun “bolting” have redirected energy toward seed production, significantly reducing their ability to generate new roots. Tender, vegetative stems are much more likely to establish a new root system.
Step-by-Step Guide to Rooting Cilantro Cuttings
Select several healthy stems and use clean scissors or shears to make a clean cut. Each cutting should be four to six inches long. Remove all leaves from the lower two inches of the stem; this prevents submerged leaves from rotting and introducing bacteria, which could compromise the entire cutting.
Place the prepared cuttings into a clean glass or jar, submerging only the bottom portion of the stems in room-temperature water. Position the container in a spot that receives bright, indirect sunlight, as direct sun can scorch the leaves. Change the water every day or two to maintain a clean environment and prevent bacterial buildup.
Roots typically emerge within seven to ten days, ideally when temperatures are between 60°F and 70°F. Once the new white roots have grown to about one inch in length, the cutting is ready to be transitioned into a soil medium. Planting the cutting before the roots are sufficiently established will likely result in failure.
Transplanting and Long-Term Care for New Plants
Once the root system reaches about an inch in length, transplant the cutting into a permanent container or garden bed. Use a well-draining potting mix, as cilantro is highly susceptible to root rot in soggy conditions. Gently create a small hole, place the rooted cutting inside without damaging the fragile new roots, and firm the soil around the base.
The newly established plant requires consistent moisture; the soil should be kept damp but never waterlogged. Cilantro thrives in cooler temperatures and prefers full sun in cooler climates or partial shade in warmer regions to help delay bolting. For container-grown plants, apply a quality, balanced liquid fertilizer sparingly to support foliage growth.
When harvesting, use sharp scissors to snip the outer, older leaves, allowing the central growing point to continue producing new foliage. This “cut-and-come-again” method prolongs the plant’s productive life. The propagated cilantro plant can continue to supply fresh leaves for several weeks until its natural annual lifecycle concludes.
