Observation of your environment is an important factor to consider. You need to observe your garden all the time in order to adapt your actions to imitate what happens in nature.
Use of natural resources:
Creating a compost in your garden will allow you to use the soil created to spread it in the vegetable garden. This soil is rich in nutrients that will be added to the soil in your garden. Other things that can add nutrients to the garden soil are manure and green manures.
Green waste such as dead leaves, grass clippings, dry stems or straw can be used in the vegetable garden in the permaculture principle. If you cover the soil with these elements, the soil will be protected and will remain moist, especially in times of drought.
