The intense flavor of dill(Anethum graveolens) has propelled it into an important culinary resource with its seeds and leaves—known as dill weed—used in many dishes, especially Mediterranean cuisine.
Avoid placing containers too close to windows due to cold air, and anywhere else they are exposed to drafts from doors or register vents. The extreme temperature variations cause internal stresses classified as chilling stress (occurring at temperatures below freezing), freezing stress (occurring at low temperatures above freezing), or high-temperature stress  , all of which hinder plant growth and yields.
Harvesting dill leaves and seeds
Dill produces a long taproot to anchor itself into the soil. To accommodate for root growth, choose containers at least 12” deep and a minimum of 6-8” in diameter. If your container does not have sufficient drainage holes in the bottom, use a drill (or similar tool) to create some, to allow excess water to drain from the potting soil.

Dill is an annual leafy herb which can be added to many savory dishes—especially soups and stews—for extra flavor. Like many herbs, dill can be grown indoors relatively easily. Dill can thrive in potting containers or pots, as long as it’s grown in the proper conditions and not overheated. Plant dill seeds in spring, so that the plants can grow in warm, sunny weather. Prior to planting your dill, purchase dill seeds, a deep pot or planter, well-draining soil, and multi-purpose compost from your local plant nursery or home and garden store.
Ensuring it’s pest and disease-free it’s time to transplant your seedling into its final home.
Dill plants need the equivalent of 5+ hours of direct sunlight [DLI of 15+ mol/m²/day] to grow their best. In order to provide an equivalent amount with a grow light, it needs to be pretty bright! The 24W Sansi bulb should be placed 6 inches away from the top of the plant. This will give your PPFD (the standard measure of brightness) of 500 μmol/m²/s.
Sprouts in 2-3 weeks. Harvest from Month 3+ on.
Where to grow your Dill plants

Particularly a good variety to grow for nice looking bunching at the market table, and works well in containers or smaller herb gardens.
How many hours per day do your Dill plants need under a grow light?
Pruning and harvesting are one-in-the-same with Dill. Once the plant at least 3 separate stems coming from the base take one of the outside leaves and cut it close to the base (½” above is fine). It’s good to leave at least 2/3rds of the plant left to regrow. If you only want a tiny amount of herbs, you also can clip the top of an individual stem – just be sure to leave some leaves on that stem, otherwise it won’t grow back.
Plants thrive on consistent moisture but can suffer if they’re waterlogged. A semi-porous ceramic self regulates ideal conditions. Our favorite is the COSWIP planter . Runner up is XS Self Watering Planter by Wet Pot .
