When's the Right Time to Move Seedlings to the Greenhouse?
Asked by g4rd3nL0v3r99
I've gone a little crazy with seed starting this year and have a bunch of perennials ready to prick out into pots. They're taking over my house, and with tomato season approaching, I'm running out of space! I know it's still early, but when can I safely move them to the unheated greenhouse? Is early April a good bet if I cover them with fleece during any cold snaps, or should I wait longer?

A max-min thermometer can be super helpful. It’ll tell you if the temps are dropping to zero overnight. Just make sure you’re aware of any big temperature variations during the day—young plants can get shocked easily. I typically air out my greenhouse during warmer parts of the day.

I totally relate! I just started around 40 tomatoes as well and my kitchen is about to resemble a jungle too. I think early April might work, but that's just my guess!

I've been keeping track of temperatures in my greenhouse and noticed they finally didn't drop below zero last night. In a couple of weeks, I'll start moving hardier seedlings in since it's warming up. Just be cautious of any unexpected frost—covering with fleece is a smart move!

I've got a cold frame in a sheltered area, and I moved some established plants out there a couple of weeks ago without any issues. I'd be cautious with seedlings, though. If they're hardy, you might be okay, but you should definitely keep an eye on the weather.

I’ve already moved mine in! You can put them out and cover them with fleece overnight. Just watch the forecast and be ready to bring them in if frost threatens. This week's looking good, so let them start acclimatizing!

A couple of weeks should be fine! Greenhouses tend to stay a bit warmer than the outside temps. Don't worry too much if you've got those hardy perennials.
