Herbs are the strongest argument for container gardening. They are compact, they are expensive to buy, and having them by the kitchen door means you actually use them.
Group herbs by what they want
The single most useful idea in container herb growing is to keep thirsty herbs apart from dry-loving ones. Basil, parsley, mint and cilantro all want steady moisture. Rosemary, thyme, oregano and sage want gritty mix and time to dry out between waterings.
Mixed pots fail mostly because one group is being watered on the other group's schedule.
Herbs that do especially well in pots
- Basil — warm, bright, regularly watered, and pinched often.
- Mint — vigorous and invasive, so a pot is the ideal home rather than a compromise.
- Thyme — shallow-rooted and happy trailing over the rim.
- Rosemary — excellent in terracotta with sharp drainage.
- Parsley — needs a deeper pot for its taproot.
- Cilantro — sow direct into a deep pot and repeat every few weeks.
Pot, soil and drainage
Bigger pots dry out more slowly and forgive a missed day. Every container needs drainage holes, and pots sitting in saucers of water will eventually kill the plant.
Use a proper potting mix, add grit for the Mediterranean herbs, and refresh the top few in each spring.
Harvest so plants keep producing
Cut above a leaf pair rather than plucking single leaves, and never take more than about a third of a plant at once. Regular cutting is what keeps soft herbs bushy rather than leggy.
Practical tips to take with you
Give mint its own pot
Mint spreads quickly and can crowd neighboring herbs. A separate container keeps it useful and manageable.
Separate moisture needs
Grow basil and parsley together, but keep rosemary and thyme in a drier mix so neither group is compromised.
Harvest before flowering
For the fullest flavor and tenderest growth, cut leafy herbs regularly before they put most of their energy into flowers.
