    Store owner replied: Hello Julia. Thank you for taking the time to share your feedback, and we are sorry for the disappointment! We’re sorry to hear they did not sprout for you. Brassicas are cool-season crops and germinate best when soil temperatures are cooler and in well-drained soil, and planting too deeply can sometimes affect germination. We’re glad we were able to provide a resolution and appreciate the opportunity to make things right. Please remember we always stand by our seeds and are here to help if you ever have questions during the growing season!
