Avoid placing your broccoli plants near extreme temperature fluctuations, as this can stress the plant and slow down growth.
Pests and Diseases
Indoor broccoli plants are susceptible to pests like aphids, whiteflies, and spider mites. Regularly inspect your plants and take action if you notice any signs of infestation or disease.
How Long Does it Take to Grow Broccoli Indoors?
Now that we’ve covered the ideal conditions and factors affecting growth, let’s talk about the million-dollar question: how long does it take to grow broccoli indoors? The answer depends on several factors, including the variety, growing conditions, and care. Here’s a general outline of what you can expect:
- Germination: 7-10 days – This is the time it takes for the seeds to sprout.
- Seedling phase: 1-2 weeks – After germination, the seedlings will emerge and develop their first set of leaves.
- Growth phase: 4-6 weeks – During this phase, the broccoli plants will grow rapidly, producing leaves and stems.
- Maturity phase: 6-12 weeks – As the plants mature, they will start forming buds and eventually produce a harvestable head of broccoli.
Assuming optimal growing conditions, you can expect to harvest your indoor broccoli crop within 12-20 weeks (3-5 months) from sowing the seeds. However, this timeframe may vary depending on the specific variety and growing conditions.
Tips for Successful Indoor Broccoli Growth
To increase your chances of success, follow these additional tips:
Start with high-quality seeds
Choose fresh, disease-free seeds that are specifically bred for indoor growing.

Q: How long does it take to germinate broccoli seeds indoors?
Broccoli seeds typically take 7-10 days to germinate when kept at an optimal temperature of around 70-75°F (21-24°C) and provided with adequate moisture. However, this timeframe can vary depending on factors such as the quality of the seeds, the soil used, and the level of humidity.
To ensure successful germination, make sure to plant the seeds at a depth of about ¼ inch (6 mm) and keep the soil consistently moist but not waterlogged. You can even use a heating mat or warm location to speed up the process. Once the seeds have germinated, transfer them to a spot with bright indirect light to encourage healthy growth.
Q: What are the ideal conditions for growing broccoli indoors?
Broccoli requires a cooler temperature to thrive indoors, typically between 60-65°F (15-18°C) during the day and around 55°F (13°C) at night. It also needs high humidity, which can be achieved by placing the pot on a tray filled with water and pebbles or using a humidifier nearby.
Additionally, broccoli needs plenty of indirect light, especially in the blue spectrum, to promote healthy growth. Placing the pot near a south-facing window or using grow lights with a similar spectrum can help achieve this. Make sure to maintain good air circulation to prevent fungal diseases.
Q: Can I grow broccoli using hydroponics or soilless methods?
Yes, broccoli can be grown using hydroponics or soilless methods, which can provide better control over the nutrient intake and moisture levels. These methods can result in faster growth rates and higher yields.
In a hydroponic system, the broccoli plants will receive a balanced diet of nutrients through a controlled feeding system. This can be particularly beneficial for broccoli, as it requires a consistent supply of nutrients to produce a healthy, dense head. However, it’s essential to ensure the system is properly maintained and monitored to avoid any nutrient deficiencies.
Q: How often should I water my indoor broccoli plants?
Broccoli plants need consistent moisture, especially when they’re producing a head. Check the soil daily, and water when the top inch (2.5 cm) of soil feels dry to the touch. Aim to provide about 1-2 inches (2.5-5 cm) of water per week, either through rainfall or irrigation.
Be careful not to overwater, as this can lead to root rot and other problems. If you’re unsure, it’s always better to err on the side of caution and underwater slightly, as broccoli plants can recover from drought but not from waterlogged soil.
Q: Can I grow broccoli indoors year-round?
Yes, with proper care and attention, you can grow broccoli indoors year-round. Since broccoli is a cool-season crop, it prefers the cooler temperatures of spring or fall, but you can still grow it indoors during the summer months.
To grow broccoli indoors year-round, make sure to provide the necessary conditions, such as cooler temperatures, high humidity, and sufficient light. You may need to use grow lights with adjustable spectrums and intensities to mimic the natural outdoor light during different seasons.
Q: How long does it take to harvest broccoli indoors?
From sowing the seeds to harvesting, broccoli typically takes around 55-65 days to mature indoors. However, this timeframe can vary depending on factors such as the broccoli variety, growing conditions, and care.
Once the broccoli head has formed, wait until it reaches a diameter of around 4-6 inches (10-15 cm) before harvesting. Cut the head off at the base, making sure to leave about 5-6 inches (13-15 cm) of stem intact to encourage the plant to produce side shoots and extend the harvest period.
Q: Can I regrow broccoli from scraps or leftovers?
Yes, you can regrow broccoli from scraps or leftovers, a process called “microgreens.” Simply place the broccoli scraps in a container with a moist paper towel or soil, and keep them in a bright, cool spot.
In about 3-5 days, you should start to see new growth, which can be harvested when the microgreens reach 1-2 inches (2.5-5 cm) tall. This method allows you to enjoy the nutritional benefits of broccoli without having to start from seeds, and it’s a great way to reduce food waste.
