    They sprouted but then got stunted

    I was so excited that I had almost a hundred percent germination. However, after they sprouted they stayed stunted. After two months, they’re still only an inch tall with one set of leaves.

    Hey Audrey,

    Thank you so much for this detailed 2-star review of the Rosemary Seeds! It's fantastic to hear that you achieved almost 100% germination - that's really impressive and shows you did everything right with the initial sprouting process.

    I can totally understand your frustration with the stunted growth after such a promising start. Rosemary can be notoriously slow and finicky in those early stages, but staying at just an inch tall with one set of leaves after two months definitely sounds like they've hit a roadblock. There could be several factors at play - lighting, soil conditions, watering frequency, or even temperature - that might be keeping them from taking off.

    Your experience is really valuable feedback for us and other gardeners who might be starting rosemary from seed. It's one of those herbs that can be incredibly rewarding once established, but the seedling stage can definitely test your patience more than expected.

    I've reached out to you via email to offer assistance. Your feedback is invaluable to us, and we are committed to ensuring your experience is positive. Thank you once again for your input.

    Keep on growing 🌻️

    Hey Kristin,

    We're thrilled to hear about your fantastic results with our Rosemary Seeds! Getting 20 plants from 25 seeds is an excellent germination rate, and it sounds like they're developing beautifully with their third leaves already coming in. You're going to love having fresh rosemary to harvest once these babies are fully established - there's nothing quite like that fresh, aromatic flavor! Keep on growing 🌻️
