"This site is an amazing resource! Very generous I bought seeds of several varieties, read blog posts about which seeds to clip and how, and about germination using a heat pad. Germination rates varied between the varieties, just about how I expected from the information provided on the site. I am satisfied and will be ordering more."

"Used the water method to germinate. Put the seeds in water on a heat mat. After sprouting planted in pots. Germination was greater than 50%. Under lights now. Looking forward to planting outside in a few weeks."

"So far so good, lots of seedlings growing right in the ground and in a plant pot. I'm not sure the seeds in the fridge will sprout, but an extra seed packet was included in my order so it's not like I lost anything. Thanks!"
