Just got this email from Tris, an online friend:

Oh, Kerry!  I wasn't able to set up my regular seed starting inside this year and have had to wait for it to warm up outside.  With our uncommonly warm early spring here in MN, I'm just chomping at the bit! ... Do you think I can start some of the "tougher" annual seeds yet?  I have marigolds, petunias, nasturtiums and a few others I collected last fall.  I know I have to wait for some of the more tender annuals but I'm aching to get out there and get some dirt under my fingernails?

Here's my answer:

Dear Tris, WHOA Girl!!! I totally get where you are coming from, but do not get seduced by these early warm days!!! As tempting as it is to declare that it is spring, and plant tender things early, you do so at your peril. Mother Nature is notoriously fickle and can hurl killing frost, even snow down on us impatient gardeners, whacking all of our plants in one fell swoop - it has happened to me numerous times.

That said, if you just can't stand waiting, there are things you can do. One of my techniques is to drag my plants in and out of the garage every morning and night, until it gets warm enough to leave them out. I have a fleet of little red wagons, donated by neighbors and friends, and bought at yard sales, for this purpose.

This article also has some ideas for extending your season and protecting your containers from frost and cold.

Protecting Containers from the Cold

So, my friend, the most prudent course is to hold your horses (and your zinnias), but sometimes that is just no fun and the risk is worth the excitement.

Heehee! Thanks for the warning, Kerry! I know we could face blizzard yet but DANG these warm days are killing me! I did throw some of the marigold seeds out in the garden. If they come up, great…if not, I have a ton left for later planting. It’s just so hard when you see the bleeding hearts, daylilies and delphinium all coming up so nicely. Guess maybe I should just buy a bouquet at the grocery store and make due with that for awhile, eh?

Thanks for saying this, Kerry! It needs to be said!

Kerry – My wife and I talked it over last night. Even though here in Detroit, our hydrangeas are 2 months ahead of schedule, we’re heeding your warning! Thanks again!

Tris and Emmon – I think we all need to sit on our hands. Either that or get some plants that are cold loving.

Wow Emmon – 2 months ahead is staggering!

Kerry: Would you say pansies are OK at this point?

Hi Emmon – Yes, pansies are amazingly tolerant of all kinds of weather (except heat). I’m going out today to buy some. Hopefully that will give me a fix so I won’t buy anything more temperamental!
