When to Plant Broccoli Seeds
As Broccoli is a cool-season crop, you can start planting seeds in cool temperature months. For best results, start sowing seeds in midsummer for a fall crop and mid-spring for a summer crop. Watch out for high temperatures, as it can affect the growth of broccoli heads.
If you’re starting seeds indoors, plant broccoli seeds 4-6 weeks before your last frost. For sowing seeds outdoors, start 2-3 weeks before the last frost.
You can also follow the instructions on the back of the seed packet for successful planting and harvest.
How to Plant Broccoli from Seeds
There are two methods of planting broccoli seeds – Starting seeds indoors and sowing seeds outdoors.
Starting Seeds indoors:
If you’re situated in colder regions, start your broccoli seeds indoors before the last frost. Here is how you can start planting your seeds indoors:
- Fill seed starting trays with fertile moist soil, preferably a good quality seed starting soil mix.
- Sow the seeds ¼ inches deep and evenly cover them with a thin layer of soil. You can soak the broccoli seeds before planting for faster germination.
- Mist the soil containing seeds or water the seed tray from the bottom for even absorption.
- Cover the seed tray with a plastic covering or use supplies such as a humidity cloning tray or seed starter propagation kit.
- After 4-6 weeks, when the broccoli seedlings reach 2-3 inches in height, transplant them to your garden.
Sowing Seeds Outdoors
For warmer regions, sowing broccoli seeds outdoors can yield faster results. Here is how you can start planting your seeds outdoors:
- Direct plant your broccoli seeds in your garden once the danger of frost is gone and the soil is workable.
- Sow the seeds in fertile soil about 1/4 -1/2 inch deep and 14-20 inches apart in rows.
- Space your broccoli seeds about 3 feet between each row, as they can grow as large as up to 3 feet in height. Providing sufficient space can help them branch out more and produce healthy broccoli buds.
- Water them lightly till the seeds germinate. Soil can be kept warm and moist for broccoli seeds to sprout.
Germination Time for Broccoli Seeds
Broccoli seeds can germinate within 5-10 days from planting. They are fast germination plants that require very little time for sprouting. For indoor germination, it can more time compared to direct sowing. To speed up the process you can use artificial lights or heating mats.
Maintenance and Care Tips for Growing Broccoli
Certain maintenance and care tips regarding watering, sunlight, temperature, and fertilizers can help your broccoli plants grow healthy.
Water your broccoli regularly for about 1 inch deep per week. Like most green vegetables, broccolis need sufficient watering to thrive and develop healthy flowering heads.
Broccolis grow best in temperatures ranging between 65 -70 degrees. This cool-season crop can be best grown between September and late November.
Broccoli plants require full sun for healthy roots and to produce high-yielding growth. Plant the broccoli seedlings in areas that receive optimum sun exposure of at least 4-6 hours with partial shade.
An occasional dose of fertilizers to your growing broccoli plants can work wonders in their growth. You can use low-content nitrogen fertilizers 3 weeks after transplanting your broccoli seedlings.
When to Harvest Broccoli
Crunchy nutritious broccoli is ready to harvest after 50-90 days from planting, depending on the seed variety. When the broccoli heads are firm and of the right color, cut the heads about 6 inches from the stem. Leaving the broccoli without harvesting for a long time can reduce its quality.
