We're north of you in Mass and we have in: cauliflower and broccoli seedlings, spinach, kale, radish, lettuce, and mesclun seed. Carrot seeds going in next weekend. Some kind soul on here pointed me to the site below where you input your last frost date and it will tell you when to plant what. Here is a link that might be useful: Planting Spreadsheet

A note on the cosmic ones (and the bright lights, too). They will need to be deadheaded every couple days to keep the show going. I redo an entire bed in July with the Bright Lights, and if I don't deadhead regularly, they go to seed on me. When deadheaded, I can get the entire patch to look gorgeous right through frost. Cosmic I've used also, and they require the same care. But the reward for your efforts is a long season of beautiful flowers. The other styles (mainly the taller ones) I haven't wanted to keep, so I did NOT deadhead them, but I did have the taller double-clicks, and they also benefitted from the frequent haircuts. Enjoy!

I'm putting a link below to the wintersowing forum faq page. It is a slow time of year there, but many of us still check in occasionally. Regarding wind blown containers... normally it is not a problem for me even here by the windy city. If the containers are on the ground tightly arranged and have enough potting mix that is not dried out they won't blow over. There are tips on windy conditions if you search the wintersowing board. Regarding the mulch. It does help greatly with the weeds and soil moisture. But, it also breaks down and gets other debris mixed in that turns it into a good medium for weed seeds to germinate in the mulch itself. The good thing though is that it keeps the ground moist, so pulling weeds is much easier. You will have less weeds with mulch than just bare ground, but it won't be weed free and no maintenance I guess it what I was saying. If you have tightly spaced healthy desirable plants they will mostly out compete and shade out the weeds whether you have a thick layer of mulch or not. My ultimate goal is to not have to buy mulch. I am trying to leave as much plant debris in place as possible and just chop it up a bit. I rake leaves into the beds a few inches deep. If I could chop them up it would be better. I use grass clippings sometimes too. It is not too late to sow annuals that don't need cold in containers or directly now. Due to bad weather I am running late this year. I am going to direct sow some zinnias, sunflowers, cosmos, dill, and a few others this week. I know what all these seedlings look like so I am able to easily weed out anything else that pops up there. That is one of the keys to direct sowing because anytime you disturb the soil and keep it moist for your seeds to germinate you are also creating the ideal condition for weed seeds as well. Wet cardboard and newspaper does work pretty well for smothering existing growth too. Good luck and be sure to check out any newbie seed offers before you purchase more seed this winter. You'd be surprised what you can get. Having a "seeds wanted" list on your exchange page before joining any offers helps adopters/sponsors know what you are looking for too. I think there is an adopt a newbie thread on the seed exchange forum now. Here is a link that might be useful: http://faq.gardenweb.com/faq/wtrsow/

Coriander doesn't like a lot of heat or a lot of sun, all of the rest will do just fine. Your cold weater will not come until about mid October or later, so you should have a little time. If it were me in Z9/10, I would have started most indoors and then planted outside in maybe March or April, to take advantage of the very long growing season.
