How Many Days Does It Take To Grow Broccoli Sprouts?

Factors That Affect Broccoli Sprout Growth


Temperature plays a crucial role in the growth of broccoli sprouts. Broccoli sprouts thrive best in temperatures between 65 to 75 degrees Fahrenheit (18 to 24 degrees Celsius). Extreme temperatures can inhibit their growth and development. It is important to ensure that the environment in which you are growing broccoli sprouts maintains a consistent temperature within this optimal range.


Light is another essential factor that influences the growth of broccoli sprouts. These sprouts require an adequate amount of light to carry out photosynthesis and produce energy. If you choose to grow broccoli sprouts indoors, make sure to place them in a location where they receive direct sunlight for at least six hours a day. If growing them outdoors, ensure that they are not overshadowed by taller plants or structures.


Proper watering is crucial for the healthy growth of broccoli sprouts. Overwatering can lead to root rot and poor growth, while under-watering can cause the sprouts to wither and die. It is important to water the sprouts consistently, keeping the soil moist but not waterlogged. Monitor the soil moisture regularly and adjust your watering routine accordingly. A foolproof way to determine if the sprouts need water is by sticking your finger about an inch into the soil. If it feels dry, it’s time to water them.


Choosing the right soil for your broccoli sprouts is essential for their growth and development. Opt for rich, well-draining soil that is high in organic matter. Broccoli sprouts prefer slightly acidic soil with a pH between 6.0 and 7.0. If the soil in your garden or container is alkaline, you can adjust the pH level using organic soil amendments. It is also recommended to mix in compost or well-rotted manure to improve the soil’s fertility and moisture-holding capacity.

Seed Quality

The quality of the broccoli sprout seeds you use directly impacts the success of your growth. Ensure that you obtain high-quality seeds from a reputable source. Look for seeds that are fresh, viable, and have a high germination rate. This information can usually be found on the seed packet or provided by the supplier. Investing in good-quality seeds increases the chances of a successful and bountiful harvest.

Germination Period of Broccoli Sprouts

Obtaining Broccoli Sprout Seeds

To start the journey of growing broccoli sprouts, you need to obtain broccoli sprout seeds. These seeds can be purchased from local nurseries, seed catalogs, or online stores. Ensure that the seeds you choose are specifically labeled as broccoli sprout seeds and not regular broccoli seeds, as there is a difference between the two.

Preparing the Seeds

Before sowing the seeds, it is recommended to give them a proper preparation treatment known as pre-soaking. This involves soaking the seeds in warm water for approximately 8 to 12 hours. Pre-soaking can help soften the seed coat and promote faster germination. After soaking, drain the excess water and proceed to the next step.

Sowing the Seeds

To sow broccoli sprout seeds, fill a seed tray or small containers with moistened seed-starting mix. Make small holes in the soil about a quarter of an inch deep. Place one or two seeds in each hole and cover them lightly with soil. Gently press the soil around the seeds to ensure good seed-to-soil contact.

Germination Time

The germination period of broccoli sprouts typically ranges from 3 to 5 days. However, factors such as temperature, light, and seed quality may influence the germination time. During this period, it is crucial to keep the soil consistently moist but not waterlogged. Monitor the seeds closely and be patient, as each seed will germinate at its own pace.

Growing Broccoli Sprouts Indoors

Choosing a Container

When growing broccoli sprouts indoors, selecting the right container is vital. Opt for a container with good drainage holes to prevent waterlogging. The container should be wide and shallow rather than deep. This ensures that the sprouts receive enough air circulation and that the soil dries out evenly between waterings. A tray or shallow pot can work well for growing broccoli sprouts indoors.

Preparing the Container

Before sowing the seeds indoors, prepare the container by filling it with a high-quality seed-starting mix. Moisten the soil adequately, ensuring it is evenly damp throughout. Gently pat down the soil to remove any air pockets and create a smooth planting surface.

Sowing the Seeds Indoors

Following the same method mentioned earlier, make small holes in the soil of the container and place the broccoli sprout seeds inside. Cover the seeds lightly with soil and press it down gently. Ensure that the container is placed in a location that receives a minimum of six hours of direct sunlight daily. If natural sunlight is not available, consider using grow lights to provide the necessary light for the sprouts’ growth.

Providing the Right Conditions for Growth

To achieve successful growth indoors, monitor and maintain the environmental conditions necessary for the sprouts. Maintain a temperature range of 65 to 75 degrees Fahrenheit (18 to 24 degrees Celsius) and ensure the sprouts receive sufficient light. Water the sprouts regularly, keeping the soil consistently moist. Periodically check the moisture level and adjust your watering routine accordingly. In approximately 2 to 3 weeks, your broccoli sprouts will be ready for harvest.

Growing Broccoli Sprouts Outdoors

Preparing the Soil

Before sowing broccoli sprout seeds outdoors, it is important to prepare the soil properly. Choose a location in your garden or raised bed that receives full sun and has well-draining soil. Remove any weeds or debris from the area, and loosen the soil with a garden fork or tiller. Mix in compost or well-rotted manure to improve the soil’s fertility and structure.

Sowing the Seeds Outdoors

When sowing broccoli sprout seeds outdoors, follow the same sowing method as for indoor cultivation. Make small holes in the prepared soil, place the seeds inside, cover them lightly with soil, and gently press down. Space the seeds approximately 2 to 3 inches apart to provide adequate room for growth.

Protecting from Pests and Harsh Weather

Broccoli sprouts are vulnerable to pests such as aphids, cabbage worms, and flea beetles. Protect your sprouts by using natural pest control methods, such as introducing beneficial insects or using organic pest repellents. Additionally, cover the sprouts with floating row covers to protect them from strong winds, heavy rain, or frost. Remove the covers once the plants mature and reach a height of around 4 to 6 inches.

Maintaining the Right Conditions for Growth

To ensure optimal growth outdoors, continue to monitor the environmental conditions. Provide the sprouts with a minimum of six hours of direct sunlight per day and water them consistently, keeping the soil moist. Regularly check for signs of pests or damage and take appropriate measures to protect your sprouts. In approximately 4 to 5 weeks, your broccoli sprouts will be ready to harvest.

Harvesting Broccoli Sprouts

Determining the Harvest Time

Broccoli sprouts are typically ready for harvest when they have developed their first set of true leaves and are approximately 4 to 6 inches tall. This usually occurs within 10 to 14 days after sowing the seeds. However, you can also harvest the sprouts earlier when they are smaller, depending on your personal preferences. Taste the sprouts to determine the optimal time for harvest, as some people prefer a milder flavor while others enjoy a more robust taste.

Harvesting the Sprouts

To harvest broccoli sprouts, use a clean pair of scissors or gardening shears to cut the sprouts just above the soil line. Avoid pulling the sprouts out by the roots, as this can damage the roots of neighboring sprouts. Harvest the sprouts individually or in small clusters, allowing the remaining sprouts in the container or garden bed to continue growing for future harvests.

Storing Broccoli Sprouts

Cleaning and Drying the Sprouts

Before storing your freshly harvested broccoli sprouts, it is essential to clean and dry them properly. Gently rinse the sprouts under cool running water to remove any dirt or debris. Shake off any excess water and pat them dry using a clean kitchen towel or paper towels. It is important to handle the sprouts gently and avoid damaging them during this process.

Proper Storage Techniques

To store your broccoli sprouts, transfer them to a clean and dry storage container. Line the container with a paper towel to absorb any excess moisture and help prolong the sprouts’ freshness. Place the sprouts in the container and cover it with a loose-fitting lid or plastic wrap. Store the container in the refrigerator, preferably in the crisper drawer, to maintain a cool temperature and maximize their shelf life. Consume the sprouts within a week for optimal flavor and freshness.

Common Problems and Solutions in Growing Broccoli Sprouts

Mold or Fungal Growth

Mold or fungal growth on broccoli sprouts is a common issue that can occur due to excessive moisture or poor air circulation. To prevent this problem, ensure that the sprouts are not overwatered and that the container or garden bed has proper drainage. Increase air circulation by placing a small fan near the sprouts or gently stirring the air around them. If mold or fungal growth persists, consider using an organic fungicide specifically formulated for sprout cultivation.

The abundance of vitamins, minerals, and antioxidants in broccoli sprouts contributes to a strengthened immune system. Regular consumption of these sprouts can help support overall health and enhance the body’s natural defense mechanisms, guarding against illnesses and infections.

Cooking and Using Broccoli Sprouts

Raw Consumption

Broccoli sprouts can be enjoyed raw and contribute a crisp texture and a mild, slightly peppery flavor to dishes. They make a nutritious addition to salads, sandwiches, wraps, and even as a topping for burgers. Use them as a garnish or mix them with other fresh vegetables for a delightful crunch in your meals.

Incorporating into Salads or Sandwiches

Broccoli sprouts add a refreshing element to salads, providing extra texture and nutritional value. Mix them with your favorite greens, vegetables, and dressing for a vibrant and healthy salad. They also work well in sandwiches, providing a crunchy texture and a boost of nutrients.

Sauteing or Stir-frying

For those who prefer a slightly cooked texture, sauteing or stir-frying broccoli sprouts can bring out a unique flavor profile. Heat a small amount of oil in a pan and add the sprouts along with other vegetables or protein of your choice. Cook them briefly over medium-high heat until they are tender but still retain their crunch.

Blending into Smoothies

Broccoli sprouts can also be incorporated into smoothies for a nutrient-packed boost. Blend them with fruits, leafy greens, and your preferred liquid base to create a refreshing and nutritious beverage.
