| I am not saying it is possible, but you could always try it. I wouldn't do it with seeds that are expensive. You could try it with flowers or plants that maybe would reseed themselves normally or even natives. Though my biggest concern would be the lack of water once they start germinating. I mean my thought on it is that mother nature takes care of the seeds normally out in the wild without our help. Though when we start confining them to a small amount of soil like some containers that also means a small amount of moisture. If not left to nurture or water who knows what may happen since the same elements are not being provided out in the wild. Does that make sense?? In other words seedlings need moisture, containers seem to dry out faster than plants that have roots established in the ground. I may try it just to see what happens, but like I said before I wouldn't try it with expensive or rare seeds. Also you could always try and have them in some kind of pan that holds water. I have always grown seeds in spring and I always put my pot or container in something that holds water. I can water one day and the next it still be bone dry. So that is another suggestion, I still do not know if it would work, though there is my thought. |

| If you said you were coming back in March, I think you would have pretty good success. I don't know what the temperatures are in Michigan in the spring, but once it starts getting warm, the seeds start sprouting and some need to be planted out or divided. Some seeds sprout while it is still cold, or if there is even one warm day. Plus rain is unpredictable, and once the plants start growing, they need more water. Do you have a neighbor or relative who could join in this experiment and check on things for you? Becky |

| Thank you for your input. I wondered about the problem of not being able to water the plants. This is what I'm going to do this year. I bought stacks of styrofoam coffee cups. I'm going to write the name of the seed around the perimeter of the cup and also insert a plastic knife with the name in the center. I'm going to fill the cup with potting soil/with seed starter mix. Then dig a hole in the ground to fit the cup and insert. Think I better put some holes for drainage also. I'm going to try half covered with something clear with holes in it. This way I might be able to tell what germinates. |

| That was going to be my other suggestion to maybe bury them in the ground. I mean it should help with the water part. I get told all the time something will not work. Each climate is so different, that what may work for you may not work for me and vise versa. I like trying new things or thinking outside of the box. Tonight my new idea is using an old parmesan cheese container. I am going to use it and I think it will work. I mean it already has the vents needed in the top. LOL |

| "fill the cup with potting soil/with seed starter mix" You really don't want to winter sow in seed starting mix - it has no nutrients for the seedlings once they've used what is in the seed itself, is very fast draining. You don't need a sterile medium outdoors where things are sterile only about a millisecond anyway...and it costs more. Covering....one of the things I was concerned about with your leaving containers unattended until May...the height of the seedlings. Depending on what you are sowing, some things are going to need tops removed for 'head height' before you are home in May. Carolyn, your enthusiasm is admirable! But, this will be your first year?.... unless you have seeds to play with, extras you don't count among your 'must have' plants...you might try what has worked most often before straying too far from the FAQs, you'll have a better idea what will work for you then. |

| Hello Mroz: You said "You really don't want to winter sow in seed starting mix - it has no nutrients for the seedlings once they've used what is in the seed itself, is very fast draining. You don't need a sterile medium outdoors where things are sterile only about a millisecond anyway...and it costs more." This sentence surprised me because I recall threads on this forum recommending starting seeds in 'seed starter' as opposed to 'soil' because soil tends to get too compacted. I have always started my seeds in 'seed starter' and so far all has been well. I am interested to know what you use that will help me save a few $$$$. |

| Northener, by seed starting mix I assumed the OP meant one of the products made specifically for growing from seed indoors, like Jiffy, Miracle makes one, others...they are a sterile, very fine (screened and pastuerized) very lightweight combo of usually just peat, vermiculite and are useful for starting flats of seeds that will be lifted out and potted up under lights. That's not the same as potting soil, or potting mediums, products formulated for growing PLANTS in pots that we use to WS...almost all of which are basically soilless and contain no soil for the reasons you mention. Actual soil (and again, potting soil is really not soil at all) is going to compact and not provide the right aeration, drainage in a container no matter how wonderful it may be in your garden beds. Confusing, I know. Potting soil isn't soil. We are starting seeds, but not in seed starting mix :) |

| Have you considered direct sowing and using row covers? This is not wintersowing, but it would provide some protection from critters and wind while allowing precipitation to get through. I know someone who has a 'flower farm' operation and this is what she does. Of course, she isn't gone for 6 months. But she does this over a large area, growing a number of seeds that require stratification. Becky |

| Morz I seriously enjoying all of your suggestions. This is my first time to winter sow, per my idea of winter sowing, yes. Though I am not new to seed starting. I of course have read the faq's and to sum up the faq's in general if you can winter sow it that primarily means that it grows through the winter or the next spring normally through out nature or the wild with NO help from humans. With that said I add my common sense to the faq's. Simplify not complicate!! Winter sowing to me personally is the same thing out in the wild confined to a recyclable container. If I misunderstood that then I am in the wrong place entirely!!! How many people seriously need 100 plants of one variety unless you have plenty of acreage?? I know I don't!! Oh and per faq's Trudi also uses Jiffy seed starting mix, ;)!! Morz are you growing the gardens in the containers or you just starting seeds?? |

| It wasn't trudi that used the jiffy mix though if I was a betting person I would of bet on that. I seriously could of sworn I saw where she wrote that she prefered the jiffy. I did read somewhere that someone used that. My bad thinking it was her!! |

| I agree- I use regular potting mix, not seed starting mix. I don't even like seed starting mix for growing under lights. I find it's texture too fine and it soon compacts. I prefer potting mix for everything. Karen |

| Unless you have someone to monitor water and ventilation needs I do not think ws will work with the extended time away. You might have some seedlings survive but expect to have a high failure rate. If you are going to be back in early May you can wait to sow your annuals then using winter/spring sowing. Annuals usually germinate and grow quickly. Also most perennials do not need cold stratification and many germinate in a few weeks so they could also be sown in May. Regarding your suggested method, why not skip the cups and just direct sow and still cover the seeds? I have done that with using 2L tops over the seeds. The tops contain the seeds and help keep them moist. I don't know your spring weather but if the temps get too high seedlings covered with 2L tops or other plastic can get too hot and burn up. Sowing in a semi-shaded area will help prevent that as will having vent holes in any plastic used to cover them. Direct sowing and using row cover sounds like a workable idea. To me gardening is a big experiment so I would try several techniques. Whatever you choose to do, please let us know the results. Good luck. Oh, I use soiless potting mix, Pro Mix is my first choice but have used most any with good results. |

| and to sum up the faq's in general if you can winter sow it that primarily means that it grows through the winter or the next spring normally through out nature or the wild with NO help from humans. Uh, no. The seeds don't sprout immediately, so they don't grow through winter. They remain dormant through winter and germinate at their own right time. For some, like many of the evergreen perennials, they will sprout at the end of winter and will survive with freezes and thaws. After seedlings sprout they don't grow quickly above ground--sometimes it may even seem like the seedlings are in stasis--they're hardly growing at all, but you don't see what's going on below the soil where the seedling roots are growing long and strong. If you want to WS in November and come back to green seedlings in May I think you'll be very dissapointed. I would only try this with very big and deep and huge patio urns because they will hold enough soil to remain moist for many months once they defrost in early spring. I would not cover them with plastic but instead leave the containers open so that the air under the plastic doesn't super-heat and cook seeds or seedlings. Hope this clarifies and helps, Trudi PS--you can always try spring sowing when you get back north. |

| Thank you all so much. I don't know what process I'm going to use yet, but I'll let you know when I've decided. I have many seeds that I think that I can direct sow, but I've never had any luck when I planted seed packets in the past. |
|
| So, where are you going to be for the winter months? Why can't you winter sow there and then bring them north in May when you return? There are plenty of zone 8 winter sowers. |

| Message to Mroz: Thanks for the explanation. I guess when you've been doing something for sometime, you don't realize what's written on the bag. I realize that my usual seed starter is also characterized as potting mix, whereas the one I use for my indoor stuff is sterile seeding mix, complete with fertilizer. And yes, you don't want to use that one!!! |

| I put growing and that was the wrong term to use. Misleading yes especially how I worded that. I should of said something like if it grows in nature or normally with NO human help then you can winter sow it. I mean me simply I take winter sowing as we use the containers in order to just not mix up the seeds or not lose them etc etc... I mean think about it if the basis of winter sowing is anything that grows naturally with no help then why do we make it so difficult. To put it simply it is confining nature to a more controllable element then what it is in the wild. We worry about our soil, well out in the nature do we put potting soil down, do we worry about seed starting mix, or does it simply grow where it got blown or where it got pooped from. Some make it so difficult, umm sorry it shouldn't be like that. I used the starting mix remark in my previous statement cause I was insulted that someone would say I need to go do some reading before offering advice acting like since I am new I know nothing. Granted I did it as a don't jump in my tail, cause I will jump back. Sorry for that also!! Though I still say simplify and common sense!! |

| In addition to what Trudi suggested, you might want to put the containers in light-total shade, and in a colder micro-climate of your yard. Perhaps on the north side of the house? This might delay the germination and growth of the seedlings, so they aren't wildly out of control when you return in May. I remember one commercial grower saying he used a cold frame, with a screened top. The screening allows the rain to penetrate, but it softens the impact of a heavy rain, which might wash away seeds down the sides of containers (I have that problem sometimes, even with milk jugs and 2 liters). |
