Personally, I like developing flower beds, garden pathways and “destination areas”…the firepit, a hammock, or a she shed. A destination is important because it gives you someplace to go in your yard, even if it’s just 50feet across the lawn. And then that “destination” becomes a focal point. And then I just start filling it in, in between. Such as a pathway to lead you there, or something of interest along the way…a garden bed, a vignette/fountain, sculpture etc. As for ‘problems’, it’s fighting back the natural vegetation as I live in a rural area, very forested. Tree roots and their suckers, keeping wild shrubs trimmed. Maintenance is always on-going. But I love seeing it change and begin to take shape little by little each year.
