Looking around my neighbourhood, as strange as it may seem, there are people (and you know who you are!) who seem fearful of plants; the fewer in their garden the better!
These guys stand out like Belisha beacons. Their plots will likely consist of trees and shrubs standing within a border no more than a metre wide, forming a military line guarding the perimeter fence.
The reason for this unfounded fear seems to be, people think the more plants on their land, the greater the work is in maintaining the flower beds. But please remember, where there’s a plant, there’s less space for weeds! The more “scary ” plants you have in your garden, the less maintenance is required.
