My grandma is guilty of this one- not so much of going potty, more that her entire garden is cluttered with potted plants. The garden becomes too ‘busy’, untidy and difficult to maintain.
Below is a solution. The red boxes below from Barbed are attached magnetically to the wall, ingenious! Apart from the height being more convenient when caring for the plants, the bright red pop of colour adds interest to the garden. Another interesting idea below is from Steckling- colourful plant pots which slot on to the balcony edge! Great space-savers.
