With so many seedlings potted up, keeping them in proper temp range becomes a challenge, running out of space an issue. The coldframe house is now quite full. The other night I used up every single flat tray I had, to shuttle all the tender ones indoors after dark. Soon the nights will be warmer (I'm looking at the forecast) but in the meantime, it really is a pain to get them all in/out of the coldframe every night/morn. So I tried something else. I wrap my coldframe house in blankets and sheets for the night.
And it worked. Temps were in the low thirties, plants unharmed. I'm not taking too many chances- I'm still shuttling in/out the tomato seedlings, peppers, basil, summer savory, tithonia and sage. That's only two flats which fills two sun-facing windowsills, so it's manageable. All the onions, marigold, nasturtiums, bigger perennials (still not pictured here, sorry!) etc stay out under the extra cover. Seem to suffer no harm.
My husband says "you have a lot of plant stuff going on right now!" He hasn't seen me so busy with seedlings and gardening before. I told him yeah- it's spring- they need more attention and care. I don't want my garden to fail again this year!
