Sadly though, you cannot do that until you actually hire someone for the job. Until they show that they are sturdy plants and not weeds, you never know. Now if due to unions or policy they do not have a system for rewarding the plants, then they are stuck with a mix of dedicated people and driftwood. Paying driftwood (weeds) more money will not produce results. It is mostly attitude.
However, since I do not know whether or not they have such a program or the ability to have such a program in place, I do not know exactly how they can improve it. Unions are good things, but, they also are the great equalizer. They create situations where weeds must be paid the same as the plant. Good for the weed, but, it sucks big time for the plants. Overall, it sucks for both.
