Growing Dill Hydroponically
Dill is takes well to hydroponic growing. Unlike herbs such as basil and parsley, dill does not keep producing foliage as it is pruned. Therefore, to assure a steady supply of dill, plan on successive plantings about every 3 or 4 weeks.
Buy seedlings or grow them yourself from seed. The very best variety of dill for hydroponic growing is `Fernleaf' dill sold in most garden centers and in many seed catalogs. `Fernleaf' is a shorter, more compact form that grows to only about 18 inches, while offering bushy foliage for snipping. ‘Bouquet’ dill is still compact but grows to about 30 inches.
Succession Planting - Plant a series of young dill plants for hydroponic growing. Start with two seedlings, then start two more in 3 weeks. In 3 or 4 more weeks, add yet another pair of seedlings among the established ones. As they mature progressively, they provide a constant supply of dill.
Light Requirements
Outdoors - Dill wants full sun if the hydroponic system is set outside, meaning 5 or 6 hours of sun each day.
Indoors - To grow dill indoors, you can set up the system on a sunny kitchen counter or near a south facing window that admits plenty of sun. However, you get much better results using artificial lighting. Flourescent bulbs are good and high intensity lights are better.
Feeding Requirements?
Harvest hydroponic dill much the same as you do with your dill out in the garden.
Dill Hydroponics:
Dill thrives in hydroponic systems and can grow even in poor soil conditions. However, using well-aerated growing mediums and proper fertilization techniques will provide optimal results.
- Succession Planting: Start multiple seedlings at intervals of 3-4 weeks to ensure a continuous harvest.
- Harvesting: Dill is most flavorful when harvested before flowering. In hydroponic systems, follow similar practices as with outdoor gardening by cutting stems in the morning or evening.
- Fertilizer: For hydroponics, a balanced fertilizer with low phosphorus, such as 15-5-10, works well for continuous foliage growth.
Growing Dill in Containers:
Dill grows well in containers. Ensure the container is deep enough to accommodate its long roots, with a minimum depth of 12 inches. Containers should be placed where they can receive 5-6 hours of sunlight daily.
Frequently Asked Questions About Growing Dill Indoors and Hydroponically
Can dill grow hydroponically?
Yes, dill grows well in hydroponic systems. Dill seeds take around 7-14 days to germinate and once established, they thrive in nutrient-rich water, providing a constant supply of aromatic foliage. Dill is also an excellent source of nutrients like vitamin C, manganese, and iron.
Can you grow dill in water?
Dill can be propagated in water using cuttings. Snip a 3-4 inch stem, remove leaves from the bottom, and place it in water. In 2-3 weeks, roots should develop, making the plant ready for transplanting into soil or a hydroponic system.
Will dill grow inside?
Yes, dill can grow indoors as long as it's placed near a sunny window or under artificial light. Keep the temperature above 60°F, and dill will grow successfully indoors throughout the year.
How long will dill last in water?
When stems are placed in water, dill can stay fresh for up to a week. Change the water daily to prevent wilting.
Why can't I grow dill?
Dill needs a deep container (at least 12 inches, but 24 inches is ideal) for its long roots. Ensure good drainage and consistently moist (but not soggy) soil. Dill also prefers full sun and may struggle in shady spots or poorly aerated soil.
