Gardening can be difficult work. A person can use an assist with many of the tasks.
Two to dig a hole and plant a post. One to bring a wheelbarrow of dirt or mulch and the second to spread it. Sometimes the assistant can be a child in training for simple things.
And some gardens are simply too large for one person to keep up with. All the trimming, planting of seasonal blooms, care of the pathways. The work requires an entire crew. A team of professionals works in many public gardens in all parts of the world. And even the team needs a small, quiet assistant now and then.

This silent assistant was spotted at Hampton Court Gardens.
Another imaginative photo……..consider a book about your way of “seeing” London!
