Hi Calliope, I know what you mean, but those plants that can be planted before frost date usually can take frost easily. My nasturtiums, e.g. went through a few snow falls last year with their beautiful leaves and flowers before they finally yielded. I agree that one must know his area well and know how to estimate (though we cannot be 100% accurate). For some annuals, I wait 2 weeks after our formal frost dates, then check the forecast for the next 10 days, and if it looks good I can plant them. For tender annuals, I might wait a little longer or start indoor. For half-hardy or hardy annuals, I can start earlier.

If they don't need cold strat, consider summer sowing outdoors using the winter sowing method. I have started lychnix and sweet william today for fall plant out.

Well, bad news today, Amazon is sold out of the Opalkas.. I will call Laurel later today and see if she has any. What I would do is do a search for "Tomato Plants for Sale, Bay are, or your city or a big city nearby. Why do I suggest that? Well I did a search for Tomato Plants "Orange County Calif". I didn't turn up any nursery that had the kind of maters I wanted, so I found Laurel and ordered them all from her. I had a dentist appointment Tuesday, and on the way home, I stopped at a local Nursery, (about 10 miles from Home). They had every mater I wanted, and nice size and price too!, GRRRRRR. I did not find that nursery when I did my search because it was in LA County!!!!! With Me, I want "Instant Gratification" with my maters, and had I done a better search, they would be in my garden now!!! I'm 70 and don't have the patience, time, or wish to take the chance on something going wrong trying to plant seeds, caring for them, light heat, water, etc, transplanting them a couple times, hardening off etc etc, so I always buy live plants. Hope you find your maters! Gary

I've enjoyed this site. It is helpful for me. As for sowing seeds inside is up to you but the time is right for sowing outdoors. If all goes well, I'll be sowing this weekend. Barb Here is a link that might be useful: what to do in your garden this winter
