Received a set of reeds end of April. Planted as instructed and of 16 plants, only one had sprouted. Contacted the seller, thinking I may not have planted them correctly. The seller responded promptly and suggested I wait a little longer.
He was right. Almost all 16 have sprouted. I was offered a refund following my initial contact, but it's not necessary. I am pleased with the way the plants are growing and I'm pleased with my contact with the seller.
