INTRODUCING CAULIFLOWER SEEDS

Cauliflower is a vegetable celebrated for its versatility. There are many benefits of cauliflower, including its adaptable flavor profile and its high vitamin C and K content. Originating from the Mediterranean, cauliflower has become a global favorite and is grown in many climates. It is suitable for growing in USDA hardiness zones 2 through 11. Cauliflower is used in many different ways, including as a meat or rice substitute, as an addition to salads, and as a side dish.

PLANTING CAULIFLOWER SEEDS

To start growing cauliflower, you can sow the seeds 4 to 6 weeks before the last fros indoors, or plant them in the garden directly in late summer. Plant the seeds ¼-½ inch deep. Cauliflower requires consistent moisture and cool temperatures for large head development. When seedlings are sturdy enough, harden off and transplant, leaving 12-18 inches between the plants.

MAINTAINING CAULIFLOWER PLANTS

Cauliflower plants need regular care. They prefer growing in full sunlight for the majority of the day, and the soil should be kept moist at all times. This vegetable is a heavy feeder and requires enriched soil for successful growth. Tying outer leaves over the heads prevents discoloration and sunburnt cauliflower. Harvesting can start when the heads are firm and compact. Cut the heads and keep a few leaves attached to protect them for later use.

Planting cauliflower seeds is a good way for gardeners to take up a fun challenge which will result in a rewarding harvest at the season’s end. This vegetable is used in so many different ways and retains its nutrients even when cooked! It’s great for pickling, canning, freezing, eating fresh, and even enjoying raw. Don’t let cauliflower intimidate you – with a little practice, you’ll be a pro at growing these nutritious veggies!

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.
