A 14-inch-diameter pot is the optimal size for a collection of herbs — large enough to do the job without becoming a major production in weight, cost and soil volume.

Herbs need great drainage — some gardeners place clay shards over the drainage hole, others just line the pot with landscape filter fabric to keep soil from washing out.

Broad, bowl-shaped containers hold moisture longer than regular pots and may drown herbs.

Glazed ceramic, concrete and resin pots tend to be freeze-resistant and can be left outside in the winter, but they should be protected against saturation. Most terra cotta pots are not frost-proof and should be brought into a sheltered and dry location in winter.

Local independent garden centers carry a large selection of attractive glazed and clay pots, many of them mass-produced in Southeast Asia. High-design resin and concrete pots are available from companies such as Campania International, Lunaform and NativeCast.

Here are a few pots that caught our eye; all are approximately 14 inches wide except the tall glazed pot, which is 11 inches.

Clay “feet” can aid drainage, especially when pots sit directly on paving. You need three for a circular pot, four on a square one. They cost about $2 apiece.
