Broccoli Seeds

Broccoli seeds grow into plants that are known to be nutrient powerhouses. This biennial plant provides many health benefits and versatility in the kitchen from its initial sprouting phase all the way through flowering. As the season is near its end, gardeners can continue to harvest crisp, green florets for fresh nutrition even in cool weather. These plants are rich in vitamins, minerals, and antioxidants. Broccoli flourishes in full to partial sunlight, requiring fertile soil.

INTRODUCING BROCCOLI SEEDS

Broccoli, a cabbage (Brassica) family member, traces its origins to Italy. The plant is known for edible green florets and stalks which are full of vitamins, antioxidants, and fiber. Broccoli seeds are very adaptable, grown in USDA hardiness zones 2 to 11. Planting times may differ based on local weather and variety.

HOW TO PLANT BROCCOLI SEEDS

The process of planting broccoli seeds usually begins indoors, 6 to 8 weeks before the last frost. For fall harvest, sow seeds directly in the ground in July. The sowing depth is 1/4 inch. Harden off and transplant seedlings once they have 2 or 3 true leaves, and space them 18 to 24 inches apart. Broccoli benefits from consistent moisture and direct sun exposure, though it can tolerate partial shade.

MAINTAINING BROCCOLI PLANTS

Once rooted, broccoli plants need regular watering to maintain even soil moisture. This is crucial for steady growth and for florets development. Slow-releasing fertilizer at planting and mid-season can support healthy growth. Monitor plants for pests and diseases. Cabbage worms and black rot are the most common issues and should be addressed promptly. Broccoli is ready for harvest when the heads are firm and before the flowers start blooming. Pro tip: cutting the central head will stimulate the production of side shoots, extending the harvesting period.

With Survival Garden Seeds' broccoli seeds, gardeners can take advantage of the entire growing season by planting them after the previous plant harvest. When the cold starts, broccoli will keep growing, offering fresh produce long after summer ends!

Frequently Asked Questions

What are heirloom seeds?

Heirloom seeds are the types of seeds your grandparents grew. These varieties have been passed down from generation to generation. They’re old reliable open-pollinated varieties that aren’t typically grown commercially. Instead, they have a rich history that predates modern breeding techniques. You can learn more about open-pollinated, heirloom, and non-GMO seeds in our Survival Garden Training blog.

How do I know my seeds are fresh?

Every seed packet includes a "packed for" date, and we germination test each seed lot before packaging to ensure you receive viable, high-quality seeds that are ready to grow.

Are your seeds chemically treated?

No, we do not pre-treat our seeds. All of our garden seeds are untreated, open-pollinated, non-GMO, and heirloom varieties. They are kept in temperature-controlled cooler storage until they are packed and shipped to keep them pest and disease-free.

Will your seeds grow in my USDA Hardiness zone?

The seeds in our collections are specifically chosen from varieties that can be successfully grown from Zone 3 to Zone 10 USDA Hardiness Zones. However, individual varieties have specific needs to thrive in different environments. Each seed pack has optimal temperatures for germination and instructions on seed starting. Consult local frost dates to plan your garden and get the most out of your seeds.

What is the shelf life of these garden seeds?

Most seeds remain viable for 3 to 5 years or longer when stored properly. Check your seed packet for specific varieties. For best results, keep your seeds in a cool, dry place away from direct sunlight and moisture. Store them in an airtight container in a consistent temperature environment—a refrigerator or cool basement works well. Proper storage helps maintain germination rates and extends seed life well beyond the packed date.

Where are Survival Garden Seeds sourced?

The majority of our seeds are sourced in the United States, with a few exceptions when the seed is difficult to source domestically. Whenever we do have to source outside of the US, we ensure our seeds are safe to grow, non-GMO, heirloom varieties that meet our standards for germination and reliability.
