Preparation for Autumn & Winter Vegetable

I have started to prepare for autumn and spring vegetables since last week.
The procedures are as follows;
1.  Harvesting all summer vegetables and removing from the roots completely
2.  Digging the ground, putting air and adding fertilizers to the soil
3.  Making four vegetable ridges
4.  Covering mulch sheet(film) depending on the planting vegetables
5.  Planting seeds and seedlings

These steps are still on the process since I started on September 1.
