Gardeners should have to be more qualified than they actually are. Really, it is more difficult to get a job as a gardener than to actually qualify for it. Illiteracy – at least in English - is common among even some of the larger and supposedly more reputable landscape maintenance companies. Many who get work as gardeners would have difficulty getting a job doing anything else. It’s wonderful for them that they have a crack at such an opportunity, but is it really fair to all of the poor hedges and branches that are going to be shredded and mangled at their hands?
