I feel blessed to have a greenhouse on this new acreage which opens up more opportunities for year-round gardening. Having a greenhouse year-round means some careful garden planning, crop rotation, and good soil restoration.
Previously on my old blog Little Mountain Haven, I shared with you our greenhouse planting schedule for our old polytunnel greenhouse (the plastic and pipes we’ve kept to build low tunnels with in our new garden). It looked something like this:
Complete Greenhouse Growing Schedule
This is our greenhouse planting schedule for year round food production.
Winter: Sow at the end of August or early September. Our greenhouse schedule for winter consists of growing beets, carrots, winter lettuce, mache, green onions, broccoli, cabbage, spinach, mustards, arugula, kohl rabi, turnips, and kale.
Spring: Sow at the end of winter around March and April. Our greenhouse planting schedule for spring includes planting overwintered greens, early planting of new potatoes, beets, turnips, lettuce, spinach, and carrots.
Summer: We prep for the summer by transplanting the crops into the ground in the middle of May. Our greenhouse planting schedule for summer includes tomatoes, peppers, eggplant, and basil.
Fall: Sow at the end of August or early September. Our greenhouse planting schedule for fall has us growing beets, carrots, winter lettuce, mache, green onions, broccoli, cabbage, spinach, mustards, arugula, kohl rabi, turnips, and kale.
I sowed all of our fall and winter crops Sept 4th & 8. Next year I’d like to reserve a corner for some earlier sowing, maybe mid-August. You don’t want to sow too early because it’s hot and can make the plants bolt and go to seed.
Our first frost this year was Sept 13th, but the greenhouse stayed frost-free and likely will until it dips well below zero. Our turnips were the first to sprout after just 2 days, the rest of the seeds have been coming up consistently since. Some crops are experimental: broccoli, cold hardy cauliflower (purple cape is supposed to be able to handle -10C/14F) and overwintering Galleon cauliflower down to -18C/0.4F) and I had some old parsnip seeds that I threw in there, they take 100 days so they might not get large enough.
I’m looking forward to all the crops filling in & will keep updating this article with photos with the progression!
