How often should container herbs be watered?

There are widely different watering needs for container herbs. Drought-hardy rosemary can persist with very little water, even until the soil is bone dry. Still, mint prefers to have its roots in moist soil. Mediterranean herbs like sage, chives, and oregano are well-suited for drying. They can go until the soil is dry at the surface before you water. A simple test is to stick your finger in the pot before watering.

Master the finger test. Stick your finger in the soil up to your second knuckle. If it's dry, water the drought-tolerant herbs at the bottom; if it's damp, wait for the moisture-loving plants. You'll save yourself a watering tragedy.

Readily modify watering with seasonal changes. Mediterranean herbs will require only half the water given to them for growth during the winter, which is sufficient to sustain them during the summer. However, those that delight in moisture must be kept duly supplied even in cold weather, and moved to sheltered nooks during heavy rains. My rosemary had a long, happy life as a result of these attentions.

Select your container materials carefully, considering the specific needs of your herbs. Choose an unglazed clay pot for rosemary and similar plants, as the soil will dry out more quickly, and your plant will be healthier. Choose plastic containers for basil, which enjoys having its roots in moist soil. Self-watering pots are good for that mint, and elevated pots allow air to circulate underneath (and prevent root rot, which plagues it).
