Why Soil-Free?
Before we dive into the how-to, let’s talk about why you might want to consider growing coriander without soil. Here are some of the advantages I’ve personally experienced:
* Reduced Pest Problems: Soil is a breeding ground for many common garden pests. By eliminating soil, you significantly reduce the risk of infestations.
* Better Water Management: With soil-free growing, you have more control over the moisture levels around your plants’ roots. This helps prevent overwatering and underwatering, which are common causes of plant problems.
* Faster Growth: Plants grown hydroponically often grow faster than those grown in soil because they have direct access to nutrients.
* Less Mess: Let’s face it, soil can be messy! Soil-free growing is much cleaner and easier to manage, especially if you’re growing indoors.
* Space Saving: You can grow a lot of coriander in a relatively small space using this method. Perfect for apartment dwellers or anyone with limited gardening space.
Materials You’ll Need
Okay, let’s gather our supplies! Here’s a list of everything you’ll need to create your soil-free coriander bucket:
* A Bucket: A 5-gallon bucket is a good size to start with, but you can use a larger or smaller bucket depending on your needs. Make sure it’s clean and food-grade if possible.
* Net Pots or Small Plastic Cups: These will hold your coriander plants and allow the roots to access the nutrient solution. I recommend 3-4 inch net pots.
* Growing Medium: This is what will support your plants’ roots. I recommend using LECA (Lightweight Expanded Clay Aggregate) pebbles. They’re inert, reusable, and provide excellent drainage and aeration. You can also use perlite or coco coir, but I find LECA to be the easiest to manage.
* Nutrient Solution: You’ll need a hydroponic nutrient solution specifically formulated for leafy greens or herbs. There are many brands available online or at your local garden center. I personally use a two-part nutrient solution for better control.
* Coriander Seeds or Seedlings: You can start from seed or purchase seedlings from a nursery. Starting from seed is more economical, but seedlings will give you a head start.
* pH Meter or pH Test Strips: This is crucial for monitoring the pH of your nutrient solution. Coriander prefers a slightly acidic pH of around 6.0-6.5.
* pH Up and pH Down Solutions: To adjust the pH of your nutrient solution as needed.
* Water: Use filtered or dechlorinated water for best results. Tap water can contain chlorine and other chemicals that can harm your plants.
* Drill (Optional): If your bucket doesn’t already have drainage holes, you’ll need a drill to create some.
* Measuring Cups and Spoons: For accurately measuring your nutrient solution.
* Grow Lights (Optional): If you’re growing indoors and don’t have access to enough natural light, you’ll need grow lights.
Setting Up Your Bucket
Now that we have our materials, let’s get our bucket ready for planting!
1. Clean the Bucket: Thoroughly wash the bucket with soap and water to remove any dirt or debris. Rinse well.
2. Drill Drainage Holes (If Needed): If your bucket doesn’t have drainage holes, drill several holes in the bottom. This will prevent the nutrient solution from becoming stagnant and waterlogged. I usually drill about 4-5 holes, each about 1/4 inch in diameter.
3. Prepare the Net Pots: Rinse the net pots or plastic cups to remove any dust or debris.
4. Rinse the Growing Medium: Thoroughly rinse the LECA pebbles (or perlite/coco coir) to remove any dust or fine particles. This will help prevent clogging in your system.
5. Place Net Pots in Bucket: Arrange the net pots evenly spaced inside the bucket. The number of net pots will depend on the size of your bucket and how much coriander you want to grow.
6. Fill Net Pots with Growing Medium: Fill each net pot with the rinsed LECA pebbles, leaving about an inch of space at the top.
Creating Your Nutrient Solution
This is where the magic happens! The nutrient solution is what will provide your coriander plants with all the essential nutrients they need to thrive.
1. Read the Instructions: Carefully read the instructions on your hydroponic nutrient solution. Different brands have different concentrations, so it’s important to follow the instructions carefully.
2. Mix the Nutrients: In a separate container, mix the nutrient solution according to the instructions. I usually start with half the recommended strength and gradually increase it as the plants grow. If you’re using a two-part nutrient solution, add each part separately, mixing well after each addition.
3. Check the pH: Use your pH meter or pH test strips to check the pH of the nutrient solution. Coriander prefers a pH of around 6.0-6.5.
4. Adjust the pH (If Needed): If the pH is too high, add a small amount of pH down solution and mix well. If the pH is too low, add a small amount of pH up solution and mix well. Recheck the pH after each adjustment.
5. Fill the Bucket: Carefully pour the nutrient solution into the bucket, filling it to just below the bottom of the net pots. You don’t want the growing medium to be completely submerged, as this can suffocate the roots.
Planting Your Coriander
Now for the fun part – planting your coriander!
1. Starting from Seed: If you’re starting from seed, sow several seeds in each net pot, about 1/4 inch deep. Gently cover the seeds with a thin layer of LECA pebbles.
2. Starting from Seedlings: If you’re using seedlings, gently remove them from their containers and carefully loosen the roots. Place each seedling in a net pot, making sure the roots are surrounded by LECA pebbles.
3. Water Gently: Gently water the growing medium with a small amount of nutrient solution to moisten it.
Caring for Your Soil-Free Coriander
Now that your coriander is planted, it’s important to provide it with the right care to ensure healthy growth.
1. Lighting: Coriander needs at least 6 hours of sunlight per day. If you’re growing indoors, provide supplemental lighting with grow lights. I use LED grow lights and find they work great.
2. Watering: Monitor the nutrient solution level in the bucket and add more as needed. You want to keep the solution level just below the bottom of the net pots. Change the nutrient solution every 1-2 weeks to prevent nutrient buildup and algae growth.
3. pH Monitoring: Regularly check the pH of the nutrient solution and adjust as needed to maintain a pH of 6.0-6.5.
4. Temperature: Coriander prefers temperatures between 60-75°F (15-24°C).
5. Air Circulation: Good air circulation helps prevent fungal diseases. If you’re growing indoors, consider using a small fan to circulate the air.
6. Pest Control: Even though soil-free growing reduces pest problems, it’s still possible for pests to appear. Regularly inspect your plants for signs of pests and take action if necessary. Insecticidal soap or neem oil can be effective for controlling many common pests.

Frequently Asked Questions (FAQ)
What exactly is soil-free growing, and why is it beneficial for coriander?
Soil-free growing, also known as hydroponics or soilless culture, involves growing plants without using traditional soil. Instead, plants receive nutrients from a water-based solution or a soilless growing medium like perlite, vermiculite, or coco coir. For coriander, this method offers several advantages. It reduces the risk of soilborne diseases and pests, provides better control over nutrient delivery, and allows for more efficient water usage. It’s also ideal for urban gardeners with limited space or poor soil quality.
What type of bucket is best for soil-free coriander growing?
Almost any clean, food-grade bucket can be used. A 5-gallon bucket is a good starting point, but you can adjust the size based on your desired yield. Ensure the bucket has drainage holes at the bottom to prevent waterlogging. Dark-colored buckets are generally preferred as they help to keep the growing medium cooler and prevent algae growth. However, if you are using a light-colored bucket, you can wrap it in dark plastic or cloth to achieve the same effect.
What are the best growing mediums to use besides perlite and vermiculite?
While perlite and vermiculite are excellent choices, other suitable growing mediums include coco coir (made from coconut husks), rockwool, and even LECA (lightweight expanded clay aggregate). Coco coir is a sustainable option that retains moisture well, while rockwool provides excellent aeration and support for the roots. LECA is reusable and provides good drainage. You can also experiment with mixing different mediums to find the combination that works best for you. For example, a mix of coco coir and perlite can provide both moisture retention and aeration.
How often should I water my soil-free coriander?
The frequency of watering depends on the growing medium, the climate, and the size of the bucket. Generally, you should water when the top inch of the growing medium feels dry to the touch. Avoid overwatering, as this can lead to root rot. Ensure that excess water drains freely from the drainage holes. In hot weather, you may need to water more frequently, while in cooler weather, you can water less often. A good rule of thumb is to check the moisture level daily and water as needed.
What type of fertilizer should I use for soil-free coriander?
Use a balanced, water-soluble fertilizer specifically formulated for herbs or leafy greens. Look for a fertilizer with an NPK ratio (nitrogen, phosphorus, potassium) that is relatively balanced, such as 10-10-10 or 20-20-20. Follow the instructions on the fertilizer package carefully, as over-fertilizing can damage the plants. You can also use a slow-release fertilizer mixed into the growing medium at the time of planting. This will provide a steady supply of nutrients over a longer period.
How much sunlight does soil-free coriander need?
Coriander thrives in full sun, which means at least 6 hours of direct sunlight per day. However, it can also tolerate partial shade, especially in hot climates. If you are growing your coriander indoors, you may need to supplement with artificial lighting, such as grow lights. Position the grow lights about 12-18 inches above the plants and keep them on for 12-14 hours per day.
How long does it take for soil-free coriander to grow?
Coriander typically germinates within 7-14 days. You can start harvesting leaves about 4-6 weeks after germination. The entire growing cycle, from seed to harvest, is usually around 8-10 weeks. To ensure a continuous supply of fresh coriander, sow new seeds every 2-3 weeks.
How do I prevent my coriander from bolting (going to seed)?
Bolting is a common problem with coriander, especially in hot weather. To prevent bolting, keep the plants well-watered and provide some shade during the hottest part of the day. You can also choose bolt-resistant varieties of coriander. Regularly harvesting the leaves can also help to delay bolting.
Can I reuse the growing medium after harvesting my coriander?
It depends on the growing medium and whether the plants were affected by any diseases or pests. Perlite and vermiculite can be reused after rinsing them thoroughly to remove any debris or salts. Coco coir can also be reused, but it may need to be amended with fresh coco coir to replenish nutrients. If the plants were affected by any diseases or pests, it’s best to discard the growing medium to prevent the spread of these problems to future crops.
What are some common problems I might encounter when growing soil-free coriander, and how can I fix them?
Some common problems include nutrient deficiencies (yellowing leaves), pests (aphids, spider mites), and diseases (root rot). Nutrient deficiencies can be addressed by adjusting the fertilizer. Pests can be controlled with insecticidal soap or neem oil. Root rot can be prevented by ensuring good drainage and avoiding overwatering. Regularly inspect your plants for any signs of problems and take action promptly to prevent them from escalating.
