First time gardener here. This year I decided to grow some tomatillos and mexican chillies in my garden. Although it was some hard work I also had a good harvest (for my first time) and fun overall. Now winter is coming and my plants are dying. I already knew that this type of plants can't stand cold weather, so I knew this day would come. Last year we were around 2-5 degrees C during winter everyday (but no frost) and under 10 C until about April, I expect this year will be the same. My question now is, what do I do with my plants?
They have lost a lot of leaves, but they actually don't look that bad (to my untrained eye). Should I just cut down whatever is remaining of them and take them to composting somewhere? I feel kinda bad because they still look alive.
Next year I want to plant again, but cut down in numbers. This year I had 10 tomatillos plants, and about 20 chilli plants. I didn't think all of them would surive (first time gardening) so I planted a lot. It turns out they did all survive!. I don't have as much time anymore to take care of them and I am frequently out of town. Next year I think I only want to keep 3+6 plants maybe. Also, I'm not really wanting to get into composting. I'm ok with taking them somewhere, or have them collected, for someone else to compost.
Also, although I do have an actual garden, I used growbags for all of my plants. What do I do with the soil? If I cut down the plants, is it ok to just spread it around the garden? We are talking about 21 growbags that can fit 3 plants each, so that's a lot of soil, I think. I don't suppose it's healthy to reuse that for next year, right?
Sorry about the long post. In summary: what do I do with my plants (and soil) now that winter is coming and they are dying? Pics attached in summer and today for reference
