When choosing a variety of dill to plant, consider the intended use of the herb. If you plan to use it for pickling, choose a variety like Bouquet that has a strong flavor. If you plan to use it in salads or dips, choose a milder variety like Vierling.
It is also important to consider the growing conditions in your area when choosing a variety of dill. Some varieties, like Fernleaf, are better suited for container gardening, while others, like Mammoth, are better suited for outdoor gardens.
Propagation
Dill is propagated using seeds that are sown directly into the soil. The seeds should be sown at a spacing of 30cm by 30cm by 45cm. It is recommended to plant the seeds near onion or cabbage fields but not parsley or carrot fields as they are related hence there might be pest and disease control challenges.
The seeds will take 10-14 days to germinate. After germination, the plants should be thinned in the rows to a spacing of 30cm apart. The thinned seedlings can be transplanted to another area of the garden or potted up for later use.
Dill does not transplant well, so it is important to sow the seeds directly into the soil. The best time to plant dill seeds is in early spring after all danger of frost has passed. The soil should be well-drained and fertile, with a pH of 5.5 to 6.5. Dill prefers full sun but can tolerate some shade.
It is important to keep the soil moist during the germination period, but not waterlogged. Once the plants are established, they require little watering. Overwatering can cause the roots to rot and lead to the death of the plant.
Overall, dill is an easy plant to grow from seed and requires little maintenance. With proper care and attention, it can provide a bountiful harvest of fresh, aromatic leaves and seeds.
Land Preparation
Before planting dill in Kenya, it is important to prepare the land properly to ensure a successful harvest. The following steps should be taken:
- Harrow the land to a fine tilth desired for vegetable and herb production.
- Incorporate well-decomposed organic manure into the soil and mix with any phosphatic fertilizer if the soil is said to be phosphorus deficient or its levels are low.
- Planting should be done when there is still moisture in the ground to assist in the decomposition of any plant material.
Land preparation is crucial because it ensures well-prepared, clean shambas for planting of the various crop seeds for the season. It is important to prepare the land as early as possible after harvesting the previous crop to give enough time for the soil to rest and regain its nutrients. This will also help to reduce the incidence of soil-borne diseases and pests.
Proper land preparation also helps to improve soil structure, which in turn enhances soil water-holding capacity and aeration. This is important for the growth and development of dill plants, as they require well-drained soils with good water-holding capacity.
Overall, proper land preparation is key to achieving a successful dill harvest in Kenya. By following the above steps, farmers can ensure that their land is well-prepared and ready for planting, which will ultimately lead to a bountiful harvest.
Planting
Dill is a popular herb that is easy to grow in Kenya. Here are some tips to help you get started with planting:
- Plant dill seeds after the last spring frost date. The ideal soil temperature for planting is 65°F-75°F.
- Sow seeds directly into the soil, placing them ¼ inch deep and about 1 to 2 inches apart in rows 6 inches apart.
- Dill seeds need light to germinate, so they should either remain bare on the surface or cover very lightly with soil, about 1/8 of an inch.
- The crop should be propagated using seeds, sown at a spacing of 30cm by 30cm by 45cm.
- Plant a group of three seeds every four to six inches, in rows spaced 12 inches apart.
- The seeds will take 10-14 days to germinate, after germination the plants should be thinned in the rows to 12 to 24 inches apart.
When planting dill, it is important to consider the location. Dill can be planted near onion or cabbage fields but not parsley or carrot fields as they are related hence there might be pest and disease control challenges. Dill prefers full sun and well-draining soil. It is also important to keep the soil moist but not waterlogged. Consider succession planting to keep a continual source of fresh dill on hand.
Fertilization
Dill requires a well-drained soil rich in organic matter. Before planting, it is recommended to add organic matter such as compost or manure to the soil. This will improve the soil structure and provide the necessary nutrients for the plant’s growth.
When it comes to fertilization, dill does not require high amounts of nitrogen. In fact, excessive nitrogen can lead to reduced essential oil content in the plant. A balanced fertilizer with a ratio of 10-10-10 or 14-14-14 can be applied during planting. Alternatively, a slow-release fertilizer can be used to provide nutrients over a longer period of time.
During the growing season, dill can be top-dressed with a nitrogen-rich fertilizer such as urea or ammonium nitrate. However, care must be taken not to over-fertilize as this can lead to reduced essential oil content and poor quality of the plant.
It is important to note that soil testing is recommended before applying any fertilizer. This will help determine the nutrient content of the soil and the appropriate amount of fertilizer to apply. Over-fertilization can lead to nutrient leaching and pollution of water sources, which can have negative effects on the environment.
Weed Control
Effective weed control is crucial to ensure a successful dill crop. Weeds can compete with dill for nutrients, water, and sunlight, reducing the yield and quality of the crop. Here are some weed control methods that can be used:
Mechanical Weed Control
Tillage is the most common method of mechanical weed control. It is done before planting or after planting in rows. Tilling land before planting kills the weeds and prepares the soil for planting. After planting, tilling can be done in rows to remove weeds that have grown. However, tilling can also damage the roots of dill plants, so it should be done carefully.
Chemical Weed Control
Herbicides can be used to control weeds in dill fields. However, it is important to use herbicides that are safe for dill and that have been approved for use in Kenya. Before using any herbicide, it is important to read the label carefully and follow the instructions. Some herbicides that can be used in dill fields include:
- Clomazone
- Flumioxazin
- Oxyfluorfen
Cultural Weed Control
Cultural weed control methods include practices that prevent or reduce weed growth. These include:
- Planting dill in narrow rows to make weed cultivation difficult
- Using crop rotation to reduce weed pressure
- Using cover crops to suppress weeds
- Hand weeding to remove weeds that have grown
By using a combination of these weed control methods, farmers can effectively manage weeds in their dill fields and ensure a successful crop.
Pest and Disease Management
Although dill is a relatively easy plant to grow, it is still susceptible to pests and diseases that can affect its growth and yield. Here are some common pests and diseases to watch out for when planting dill in Kenya:
| Pest/Disease | Symptoms | Management |
|---|---|---|
| Dill caterpillar | Damaged leaves and stems, webbing | Handpick and destroy affected parts, use insecticides if necessary |
| Leaf spot | Brown or black spots on leaves | Practice good field hygiene, avoid overhead irrigation, use fungicides if necessary |
| Root rot | Yellowing and wilting of leaves, stunted growth | Plant in well-draining soil, avoid overwatering, use fungicides if necessary |
It is important to monitor your dill plants regularly for signs of pests and diseases. Early detection and management can prevent further damage and ensure a healthy crop. In addition to the above management practices, here are some general tips for preventing pest and disease infestations:
- Rotate crops to prevent soil-borne diseases

- Use certified disease-free seeds
- Choose pest-resistant varieties when available
By following these pest and disease management practices, you can ensure a successful dill crop in Kenya.
Harvesting
Harvesting dill is a simple process, and it’s best to harvest it before the flowers bloom. The leaves can be harvested as soon as the plant reaches about 8 inches in height, which usually takes around 40-50 days after planting. The leaves can be harvested by cutting the stems at the base of the plant.
When harvesting dill, it’s important to remember that the leaves have the best flavor when they are harvested before the plant starts to flower. Once the plant starts to produce flowers, the leaves will begin to lose their flavor. Therefore, it’s best to harvest the leaves before the plant flowers.
After harvesting the leaves, they can be used fresh or dried for later use. To dry the leaves, hang them upside down in a warm, dry place until they are fully dry. Once they are dry, store them in an airtight container away from direct sunlight.
It’s important to note that dill seeds can also be harvested for use in cooking or for planting in the next season. The seeds can be harvested once they have turned brown and are starting to fall off the plant. Simply cut the seed heads off the plant and place them in a paper bag to dry. Once the seeds are fully dry, they can be stored in an airtight container for later use.
Post-Harvest Handling
Post-harvest handling is a crucial aspect of dill farming in Kenya. Proper handling techniques help to preserve the quality of the harvested dill and prevent losses. The following are some post-harvest handling practices that are recommended for dill farmers in Kenya:
- Harvesting: Dill should be harvested when the seeds are fully mature and the seed heads have turned brown. The plants should be cut at the base using a sharp knife or sickle. Care should be taken not to damage the seed heads during harvesting.
- Drying: After harvesting, the dill plants should be dried in a well-ventilated area away from direct sunlight. The seed heads should be spread out in a single layer on a clean surface such as a tarpaulin or a mat. The drying process can take up to two weeks depending on the weather conditions.
- Threshing: Once the dill plants are dry, the seed heads should be threshed to remove the seeds. Threshing can be done manually by rubbing the seed heads between the palms of the hands or mechanically using a threshing machine.
- Cleaning: The seeds should be cleaned to remove any debris such as chaff, leaves, and stems. This can be done using a winnowing basket or a screen. The cleaned seeds should be stored in a clean, dry, and well-ventilated area in airtight containers.
Proper post-harvest handling practices can help to reduce losses due to spoilage, pests, and diseases. It also ensures that the quality of the harvested dill is maintained, thereby increasing its market value.
Marketing and Value Addition
Marketing and value addition are important aspects of agriculture that can help farmers increase their revenues and create more job opportunities. Dill is a versatile herb that can be used in a variety of ways, making it a valuable crop for farmers to grow. Here are some ways to market and add value to dill:
- Sell fresh dill to local markets, restaurants, and supermarkets. Fresh dill has a short shelf life, so it’s important to sell it quickly after harvesting.
- Dry dill and sell it as a spice. Dried dill has a longer shelf life and can be sold in larger quantities.
- Create dill-infused oils, vinegars, and dressings. These value-added products can be sold at higher prices than fresh or dried dill.
