Prof. Samuel Fitzgerald, Ph.D.Herbs that require special containers include those with peculiar roots or habits, such as mint, which must be isolated, and parsley, whose taproot will need deep pots. By using the proper receptacles for the various types of herbs, we avoid many difficulties that arise from overcrowding or the roots becoming too wet. Your herbs will thrive if their requirements are met.
Mint Family
- Container Type: Isolated plastic or ceramic pots
- Reason: Aggressive roots invade neighboring plants
- Minimum Size: 12-inch diameter with no drainage saucer
Taproot Herbs
- Container Type: Deep 'Long Tom' planters
- Reason: Accommodates vertical root growth (parsley, dill)
- Minimum Depth: 14 inches for mature plants
Moisture-Sensitive
- Container Type: Self-watering systems
- Reason: Maintains consistent hydration (basil, cilantro)
- Features: Reservoir with wicking mechanism
Grow mint separately in pots without drainage saucers. Its roots will try to escape from this drainage hole. Use a solid-bottom container instead. I grow peppermint in topped-out plastic buckets (without drainage holes) and prevent it from taking over the garden completely. Pick often to tame it.
Plant taproot herbs, such as parsley, in long-tom pots (the longer the better). These provide 14 inches or better in depth for the roots to run straight, and you avoid the curling up of roots caused by planting in shallow containers. My parsley grows most satisfactorily in long pots, watered from time to time.
For moisture-sensitive basil, self-watering containers are an optimal solution because the reservoirs keep your basil hydrated when it's hot. For summer refills, about 3-4 days. My basil stays perky without my involvement every day, avoiding the need for refills. It's essential to note that self-watering containers should be avoided for drought-tolerant herbs.
Choose non-glazed clay pots for growing Mediterranean herbs such as rosemary. Unglazed clay dries excess moisture easily; place pots on feet to allow air to circulate. Water the plant only when it is scorched. My rosemary can survive the winters sitting by the sunny window.
