Planting Details
| Row Spacing | 24" – 36" |
|---|---|
| Seed Depth | 1/4" |
| Seed Spacing | A group of 3 seeds every 24" |
| Thinning | When 2" tall, thin to 1 every 24" |
| Germination | 8 – 10 days |
| Start Indoors | RECOMMENDED. 4 to 6 weeks before transplanting outside after your average last frost date, or 12 weeks before your average first fall frost date. In mild climates, sow in fall for harvest in late winter and early spring. Ideal soil temperature for germination is 70°–85°F, cooler (60°F) growing temperatures thereafter. |
| Direct Sow | Not recommended. 1 to 2 weeks before your average last frost date, or 10 to 12 weeks before your average first fall frost date. In mild climates, sow in early fall for winter harvest. |
| Special Care | To ensure white rather than off-white or yellow heads, you can gently tie up the leaves or bend a few leaves, breaking the mid-rib, and tuck them across the head for sun protection (blanching). |
| Growing & Harvesting | Harvest heads in the morning, if possible, and when buds are tight. Cut stalk below the head. Dunk heads in ice water to reduce any "field heat" and increase storage time. Allow to drain before storing. |

They were very small
Which best describes you as a gardener? BeginnerBIBotanical Interests1/20/26Hey Debbie,
Thank you for taking the time to share your feedback about the Twister Cauliflower Seeds. We're sorry to hear that the seeds were smaller than you expected—we understand that can be disappointing when you're excited to get your garden started.
Cauliflower seeds are naturally quite small compared to other vegetable seeds, but we know that doesn't make it any less frustrating if they weren't what you were hoping for. Your feedback helps us understand what our customers are experiencing, and we really appreciate you sharing your thoughts with us.
We hope you'll still give them a try in your garden—sometimes the smallest seeds can surprise you with amazing results! Keep on growing 🌻️

Giant firm heads of cauliflower! Great for freezing slicing and grilling, delicious! It is May 13th and I am awaiting the final head to fully mature as temperatures approach 100 degrees! I will definitely grow this variety again.
