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.

Mine are already up and nice size already.They are still small enough to move however, so I shift them around a little.

It's not too late to direct sow annual poppies - you could do it any time now until well into March/earliest Spring.

Last year I did my Poppies on April 29th and had sprouts by May 8th so I would say that you have plenty of time. Poppies are one of the easier plants to grow in jugs. Strouper
