A productive coffee crop starts long before a seedling reaches the field. For professional growers, propagation is one of the few stages where you can closely control the young plant’s growing environment, root development and uniformity.
That early control is especially useful in coffee. Seedlings may eventually be planted across slopes, elevations and soil types that behave very differently from one another. In Colombia, for example, drainage, soil depth and structure can vary considerably even within the same farm.
As we explored in our recent look at coffee soil types and nursery choices, a consistent nursery environment can help reduce one source of variability before plants enter those changing field conditions.
Why Coffee Nurseries Are Moving Beyond Polybags
Traditional coffee nurseries have commonly relied on polyethylene bags filled with field soil. It is a familiar system, but scaling it up means managing quite a bit before a seedling ever leaves the nursery.
Growers may be dealing with:
- Thousands of plastic bags that eventually become waste
- Large volumes of fertile soil that need to be sourced and transported
- Weed seeds, pathogens or other variability introduced through field soil
- Heavy containers that require more handling throughout the nursery
- Roots that can circle or deform when they reach a rigid container wall
At small scale, each issue may seem manageable. Across thousands of coffee seedlings, the labor, material and logistical demands become much more significant.
What Changes When the Container and Substrate Become One
A Jiffy Pellet combines the growing medium and container in a single compressed unit. Depending on the formulation, pellets are available with peat, coir or blended growing media. Growers expand them with water before sowing or moving a germinated seedling into the pellet.
Instead of filling bags with field soil, growers hydrate the pellet and establish the plant directly in a uniform propagation medium.
Pellets arrive dry and compact, reducing storage and transport volume. In the nursery, the uniform growing medium provides a consistent environment around developing roots.
When pellets are raised above the ground with air circulating around them, exposed roots are air pruned instead of circling against a rigid container wall. At transplanting, the seedling can be planted with the pellet intact, limiting root disturbance.
Getting Started with Jiffy Pellets in a Coffee Nursery
Choose the pellet and prepare the nursery. A good size for coffee is the Jiffy Pellet 50 × 150 mm with peat or coir growing medium. Place pellets on a raised, open support so air can circulate around them. Protect seedlings from excessive rain and adjust shade to local light conditions.
Choose how to sow. Seeds can be sown directly into fully expanded pellets. Alternatively, they can be germinated in a peat or sand bed, then moved into pellets once roots have developed. In either method, take care to position the seed or root correctly to avoid deformity.
Adjust irrigation and nutrition. Monitor pellet moisture and irrigate according to conditions, using fine droplets for even watering and avoiding waterlogging. The coffee guide also calls for a fertilization plan once about half the seedlings have expanded their cotyledons.
Transplant when the plants are ready. Nursery time will vary with growing conditions. Good to move the plants to the field when they have three or four pairs of true leaves. Gradually acclimate them to stronger sunlight before planting.

Colombia is Already Putting the System to the Test
Colombia provides a useful example of what this shift looks like at scale.
The Federación Nacional de Cafeteros (FNC), the Colombian Coffee Growers Federatio, has been working to reduce the use of fertile field soil and plastic bags in coffee propagation. That transition is taking place alongside Colombia’s efforts to phase out specified single-use plastics, including measures established under Law 2232 of 2022.
Cenicafé, the research center of the FNC, has also conducted extensive trials comparing coffee seedlings propagated in Jiffy Pellets with seedlings grown using traditional nursery methods.
Cenicafé’s published technical guidance draws on two coffee nursery research projects conducted at its Naranjal Experimental Station between 2015 and 2021. The work helped establish practical recommendations for producing coffee seedlings in compressed peat pellets.
According to Jiffy’s reporting on the Colombian project, the research found:
- No significant difference in yield between pellet-grown seedlings and those produced in traditional plastic bags
- Strong, well-balanced root systems in pellet-grown plants
- Improved transplant success and lower plant losses
- Reduced weed pressure and simpler nursery management
- Logistical advantages from handling a dry, compact propagation product
The takeaway is not simply that a different container can be used. The trials indicate that growers can change the propagation system without sacrificing the field performance they expect from the crop.
Where the Nursery Becomes More Efficient
For growers evaluating a propagation change, some of the most practical benefits show up in day-to-day nursery operations.
Less soil to move. Because the growing medium is already contained within the pellet, nurseries can reduce their dependence on large volumes of fertile field soil.
No fossil-based plastic nursery bags to discard. Jiffy Pellets use PLA netting made from plant-based material derived from corn starch. The netting is fossil-plastic-free and certified to EN 13432 for biodegradability and compostability under controlled industrial conditions. You can read more about Jiffy’s biodegradable netting technology.
Simpler transport and storage. Pellets are shipped dry and compressed, reducing the weight and volume to store and transport. Growers expand them with water before use.
Less root disturbance. Seedlings can be planted with the pellet surrounding the root ball rather than being removed from a plastic bag before transplanting.
For large nurseries, those changes can mean fewer materials moving through the operation and a more standardized process from seedling establishment through planting.
International Coffee Day: A Look at the Nursery
International Coffee Day is observed each year on October 1 as a celebration of coffee and the people who produce it around the world.
Much of the attention naturally goes to the mature crop, harvest and finished cup. But many of the decisions that shape a coffee plant’s future happen much earlier, beginning in the nursery.
Propagation cannot control the weather, field soil or every challenge a grower will encounter over the life of a coffee planting. It can give each seedling a more consistent starting point before those variables come into play.
Strong coffee production starts with strong nursery practices and thoughtful choices about how seedlings are propagated, handled and prepared for the field.
