Potted Dill Plant Care
The most important thing to keep in mind when growing dill in containers is the depth of your containers. Dill grows a long tap root, and any container shallower than 12 inches (30 cm.) won’t provide enough space for it. That being said, your container doesn’t need to be extremely deep. Dill is an annual, so it doesn’t need extra space to build up a big root system over the years. One to two feet (30-61 cm.) deep should be plenty. You can sow dill seeds directly into your container. Fill it up with any soilless potting mix, making sure there are drainage holes in the bottom, first. Dill will grow in most types of soil, though it prefers well-drained, slightly acidic soil. Sprinkle a few seeds on the surface, then cover them with a very light layer of potting mix. Potted dill plants need 6 to 8 hours of sunlight per day and warm temperatures above 60 degrees F. (15 C.) to sprout. If all danger of frost has passed, you can keep your potted dill plants outside, but if it’s still early spring, you should keep them indoors in a sunny window or under a grow light. Keep the soil moist by misting often. Once the seedlings are a few inches (8 cm.) high, thin to one or two per pot and care for as you normally would out in the garden.
