Just finished making a yard house for my son by using wood from old furniture only. (0 euro budget). You can see my olive trees in the background. I let the weeds grow in that part, it's healthier for the yard.
I learned a long time ago on /pol/ that if there are parts of your yard that you dont visit daily, let the weeds grow, it attracts pollinators and it's better for the overall area and nearby decorative bushes and flowers
