I have had a poly tunnel on my plot for a couple of years but have never tried growing over winter. I have had really successful crops of tomatoes and chillies over the summer but I am keen to see if my poly can be equally productive during winter. I chose 5 plants to try out: Mizuna, Spinach, Pak Choi, Choy Sum, Chop Suey Greens.
The seedlings are currently looking very happy, although the spinach had a very poor germination rate leaving me with only 3 seedlings. The seeds were sown in organic seed compost in a bright shed and then placed out into the poly once they germinated. I am using a capillary matting technique to ensure the seedlings are kept moist from below, as I don’t visit the allotment as frequently this time of year. My next step will be to thin out the seedlings and wait until they have 2 sets of ‘true’ leaves before planting them into the ground in the poly.
I’ll post an update so you can see how I’m getting on, or join me in trialling growing winter greens yourself. If you’ve already had experience growing over winter, then comment with any advice to share.
