One thing you either might have to watch out for or embrace is something I call Garden Creep. This is the ability of certain gardens, let alone the plants in them, of slowly growing and spreading or even multiplying over time. Any dedicated gardener can explain to you the visible symtomology of the disease. New garden growths appear almost randomly at times as new outbreaks of gardens pop up in sometimes rather unexpected corners and sections of the area.
This problem is also seen in certain plants as well. When they have managed to obtain a foot hold in an area, where the available space for them, is adequate for their realistic size. You will find these plants spilling outwards or upwards into space they were never intended to occupy. This causes constant problems for entryways & walkways, as well as air space occupiers like power lines. These plants then have to regularly attacked and kept back within their territory, often at great cost in time and money to their garden owner. Law areas and sometimes even pathways in it's way are encompassed and / or swallowed up. It even can escape from your area onto and around footpaths and along road verges. It appears I reckon to be a potentially viral disease that affects both the gardens and their gardeners alike. It means that these garden areas extend over a period into every little space they can infect and take over, sometimes far outside the originally bounded boundaries of the initial garden / s.
