Grow Professional-Quality Container Herbs
Container herbs provide some distinct advantages to growers of all abilities — commercial growers and their retail customers, as well as home gardeners. Along with the versatility and portability that container herbs provide, herbs in containers offer added longevity and marketability. Here are some recommendations from Johnny's Research Team to help bring you optimal success with container herb production.
Benefits of Container Herb Production
Benefits to Growers

- Time to Market. Potted herbs have a quick turnaround time of 4–8 weeks, depending on the variety. See Container Herb Production Time-Table, below.
- Return on Investment. Fresh herbs are a high-value crop, with a favorable return on investment.
- Shelf Life. Depending on the variety, potted herbs can last for several weeks with proper care. If you are marketing directly through a farmers' market or farmstand, unsold pots can easily be maintained until your next market day. Fresh-cut herbs have a much shorter shelf life and don't hold up well to handling.
- Ornamental display. Potted herbs display nicely at market alongside vegetables and flowers by adding elements of visual and aromatic interest.
Benefits to Consumers
- Quality. Because potted herbs are living plants, they provide optimum freshness and a much longer shelf life than fresh-cut herbs. This gives your customers a high-quality product that they appreciate, as well as the added convenience of a longer storage period.
Success with Container Herbs

Follow these recommendations to help ensure your success with container herbs.
Start out with popular and easy-to-grow crops.
Select varieties with demonstrated container performance.
- For long-lasting, attractive, and filled-out containers, select varieties that are compact, densely branched, and slow to bolt, such as Compact Genovese Improved Basil and Fernleaf Dill .
- For a quicker turnaround time, choose faster-growing varieties such as Standard Genovese Basil and Bouquet Dill . (Note that while these varieties will result in a faster crop time, they have the potential to become tall, unruly, and may bolt faster in a container than more compact varieties.)
- Some potted herbs will maintain a good appearance longer than others. For example, crops like Dill and Cilantro can bolt quickly in hot conditions and will not be marketable once this has occurred. Herbs such as Thyme and Rosemary and even Basil can be trimmed to prevent bolting and increase lateral branching, which has the potential to improve the appearance and yield of the plant. Trimmings from overgrown plants can be marketed as fresh-cut herbs.
Grow an assortment and time your plantings.
- Offer your customers an assortment of culinary herbs to pique their interest. Crop times vary, so careful scheduling is necessary to supply a consistent assortment.
- To compare germination times, weeks to transplant days to harvest, and annual-perennial status by growing zone, consult our Herb-Growing Comparison Chart (PDF)
Offer specialty varieties.
- Paravert Parsley . With its dense and upright plant habit, Paravert creates a very full and attractive container and has exceptionally sweet flavor, making it ideal for fresh use. Paravert has a unique, tightly-curled upturned leaf known in Europe as a Paramount type, where it is often marketed in bunches with other fresh vegetables for making soups and stews.
- Sweet Thai Basil . A key component in authentic Thai cuisine, this variety can also be used as an elegant garnish for deserts and drinks. This basil's fairly compact habit, smaller leaf size, and purple stems and blooms make it an attractive variety for container production.
- Greek Basil. Varieties such as Pluto, Spicy Bush, and Spicy Globe have a rounded, bush-like habit that creates an almost irresistible boxwood appearance in a pot. The flavor of Greek basil is similar to standard Genovese but spicier. The leaves are small and can be pinched and sprinkled onto dishes without chopping.
- Other Standout Choices. Additional specialty herbs that perform well in containers include Garlic Chives; the red basils Amethyst Improved , Purple Ruffles , and Red Rubin ; Lime Basil ; and Greek Oregano .
Plan to offer seasonal culinary pairings.

- Grow herbs that pair well with your seasonal assortment of vegetables.
- Time your plantings so that herbs are ready to harvest with the vegetable crops for culinary pairings. Examples:
- Dill, Parsley, and Chives with new potatoes and cucumbers for cold salads and pickles.
- Basil, Cilantro , and Oregano when tomatoes are in season.
- Thyme, Rosemary, Sage and Marjoram with root vegetables, winter squash, and potatoes for roasting, soups, and stews.
Use containers of appropriate size.
- 3–6" diameter pots are commonly used for retail herb production.
- We recommend a 4" diameter pot to provide a nice balance between space considerations and growing an optimal plant size for good market appearance and value.
Sow according to recommendations.
- Seeds can be sown directly into the retail container OR sown into a plug tray and transplant into the retail container, 2–3 weeks later, to finish.
- Refer to Johnny's Growing Information, located on our website and seed package backs, for variety-specific sowing recommendations.
- Organic Herb Plugs. Among the many prized culinary varieties that can only be obtained commercially through vegetative propagation are French Tarragon and True Peppermint . Johnny's Organic Herb Plugs are easy to use (simply transplant one plug per 4" container), and provide a sturdier, more compact and dense habit — ideal for creating full and attractive containers.
