I was able to source some seeds for winter-growing tomatoes. I planted them back in January and have now planted the seedlings out. Some are in this bed in the greenhouse, which I part-filled using the no-dig layering method. Others I have planted in the vegetable garden. I am skeptical about the future of the outside ones, given the frosts we have here in the valley.
Layer one: several layers of overlapped newspaper.
Wet each layer well as it is added.
Layer Two: straw
Layer Three: animal manure.
Layers Four, Five, Six (as many as you want): repeat of previous layers.
Each seedling is planted in compost, nestled in the top straw layer and watered in well with seaweed extract.
