Dill is a fern-like, fragrant plant with a great flavor. In addition to its fragrant foliage, dill also produces yellow
blooms that can be used in bouquets, or the green ferns can be used as filler. Dill can reach up to 3 feet tall.

Before Planting: Dill grows best sown directly into the garden in the early spring after the last frost. To ensure a continuous harvest, plant dill seeds every 10 days up until the early summer. Dill also can be planted in containers, like most herbs, but a deep pot should be used to accommodate for the herb’s deep roots.

Planting: Plant seeds ¼ inch deep and 18 inches apart.

Watering: Water regularly. Be careful not to over-water and allow the soil to go dry between watering

Fertilizer: Similar to most herbs dill does not require fertilizing to grow. In the late spring, a light feeding of a 5-10-5 fertilizer will encourage the dill to grow without being overbearing. If dill is grown in a container, use a liquid fertilizer but only use half of the label’s recommended strength. Fertilize container dill every four to six weeks.

Days to Maturity: Dill is ready to harvest any time before its yellow, umbrella-like flowers begin to open. (See each variety for days to maturity)

Harvesting: Once dill is ready to harvest, you can snip individual stems or pull up the entire plant. To save the dill seeds, cut the dill four inches below the flower head once seeds begin to turn brown. Hang the clippings upside
down in paper bags to catch the seeds as they dry and fall out.

Tips: Since dill can grow so tall, shelter it from wind or add a stake to the stem to support the plant as it grows higher.
