Very cool dude! Glad your gardens are doing well! I was curious to know what the climate is like in the region where you are? Where on the continent, by the way?
Is it a dry and rainy region?
The earth seemed very compacted by the photos, did you have difficulty breaking the clods? The ideal is to take a day off just to crumble clods with your hands or some instrument. The looser the soil is, the better it will be for the plants! And about this sawdust, is it to avoid growing weeds around vegetables and fruits? Here in Brazil there is a variation in the cultivation methods that suggest that it is important to let the native vegetation grow in the middle of the plantations, even if it becomes a visual mess, because this will be the natural defense of the plants you will grow.
Success for you!
