Dill is often used for culinary purposes, especially when cooking fish like salmon, and it is an excellent herb to grow in a container. If it's provided with adequate growing conditions, it can grow more than three feet high. Container gardening gives you the power to control every aspect of your plant’s growing conditions. You have the freedom to reposition the plant in or out of the sunlight and your home, shielding it from overexposure to sun or frost.
Step 1 - Prepare Containers for Planting
Dill grows a long tap root, which means that it needs to be planted in a deep container to reach its full growth potential. Use a container that is at least one foot, but no more than three feet deep. Although the plant grows a long tap root, a pot larger than three feet deep is unnecessary because it's an annual plant that establishes itself in one season. A larger container may encourage the herb to focus its energy on growing roots instead of foliage.
Fill the bottom two inches of the pot with gravel to aid in drainage. Fill the remaining space in the container with a nutrient rich and well-draining potting soil mix. You may also choose to use soil-less potting mix, which may hasten germination.
Step 2 - Purchase and Plant Seeds
Purchase your seeds from a nursery instead of a department store. Nurseries are more reliable when it comes to seeds, because they specialize in gardening. Choose a variety that is suited to thrive in your particular climate zone. It may be helpful to speak with an experienced professional before you decide on which seed packet to purchase.
Sprinkle your dill seeds over your container and cover them with a light dusting of potting soil. Make sure that the soil is moist but not saturated during planting. It is best to plant the seeds in early spring, immediately after the last sign of frost has dissipated.
Step 3 - Raise Seedlings with Care
Your dill seeds should sprout within two weeks if they receive at least six hours of sunlight a day and are kept in temperatures between 60 and 75 degrees. Make sure to check on the seeds and seedlings every other day, and supplement their soil with water by misting them. During the first four weeks of growth, keep the soil moist and let sun exposure range between six and eight hours each day.
In time, your dill plants should grow to reach healthy proportions and will provide you with a source of delicious herbs. When fall approaches, allow your dill plants to go to seed, and the next year they should sprout and grow all over again.
