Did Winter Sowing Work??? Seedling Update 

Thanks for sharing. None of my poppy and snapdragon seeds came up this year. I'll be looking again for them next year.Our winters have major temperature changes throughout also. I have had on many occasions seeds that I plant one year come up the following year. Last year I had a ton of cucumbers in places which I had not planted them. Then I remembered, I planted those seeds in those places the year before and they never came up. As fare as winter sowing in jugs, I also have St John's Wort up in a jug from the year before last. Absolutely crazy but, I am very thankful! I tend not to give up on things for this reason. He works in mysterious ways.

What garden zone are you? I live in zone 5B and did some winter sowing. Some success and some not.......Nancy

I think you screwed up. I made a similar mistake like you did, and more than 1 time by the way. When you transplant your plants you will be disturbing, and maybe killing the roots of your plants. I ended up killing some of my plants because I destroyed the rooting system due to planting too many plants together. What I overlooked just like you is the proper process of planting. I spent quite a bit of my time researching how gardeners grow their plants, and I found a pattern. The pattern that I found just, so happened to be a different method of growing plants. We both had a similar style of growing our plants, but I recently changed my setup to fix my incorrect way of growing plants. I am going to pretend I never heard you say anything about using jugs to germinate your seeds. Maybe you could have germinated your few year old seeds, and I think the problem is the jugs, but it could be the seeds. I never used jugs to germinate my seeds, and I never saw, or heard of anyone who tried using jugs either ! I am aware of seeds having an expiration date, so maybe older seeds will not grow. Just try using seeds that are within 1 year of age. Lastly what happens when a gardener germinates his, or her seeds like you, and I did well the plants fight, for resources, so this is why your results are not looking too good such as some plants grew, and look healthy, and others did not.
