|My seedlings want to go outside, but it's too cold and snowy!|
Why? Because, in all likelihood, the soil won't be ready for us. After all the snow melts, the soil underneath will be damp, wet, or even soggy; if we get typical March rains, it might be flooded in spots. You may be tough enough to go out and dig in the chilly rain, but you won't do your garden any good. Working wet soil can ruin the potential for good plant growth all spring and even into summer. Wet soil is easily compacted when you step on it, till it, or turn it over with a shovel, and compacted soil loses the necessary air spaces between soil particles that plant roots need to thrive. And the thick clumps of soil that form when it's worked wet are really hard to break up when they dry into rock-like masses.
How do you tell when the soil's ready for you? Grab a handful of it, and form it into a ball. Can you squeeze water out of that ball? Then it's definitely not ready. Can you break the ball up easily with your fingers, and does it fall apart into crumbly particles when you drop it? Then you are good to go. If not, wait another week and try again.
Raised bed gardeners and container gardeners, you may get a jump on the season over your in-ground friends, but watch cold soil temperatures and drainage issues. I've got some pots out there (that did have surviving cilantro in them until recently) with two inches of water on top despite plenty of holes in the bottom - the potting soil in between is frozen and won't let water through, and is going to need a whole lot of fluffing up before I can plant anything in it (or I'll just dump it and start over).
Those seedlings up above? My calendar says they should go out in the cold frames next week. That is, if I can find my cold frames under the snow...
