It Is Your Garden sees major problems with using hobby gardeners to perform professional services. Hobbies and interests are a past time. You do things your way, everybody else is wrong and needs to learn from you attitudes are common.
This is not the professional way, a professional landscape gardener knows they have to continue to learn and they don't always know best. A professional knows their strengths and their weaknesses. A true professional in any industry specializes in a particular field of expertise, they may well know plenty about other fields, and where to get help if they get stuck, but get them started on their expertise and you will see them come to life. Producing superior results in just one field of expertise, and good results in all other fields of their industry is the sign of a true professional.
For this reason It Is Your Garden does not employ hobby gardeners, only time served professionals. All staff are experienced professionals with an identified field of expertise. They all agree to partake in further training, and to train each other as needed. Above all they know how to conduct themselves, where to get help and advice, their strengths and their weaknesses.
All pesticides are assessed when licensed for use for their risk of damaging the environment they are intended for use in. Herbicides are a Pesticide designed to be used to control plant growth and thus fall under this same assessment.
If a product is licensed for plant control it is then categorized. Field of use (Plant Control), Intended industry (Horticulture, Agriculture, Amenity), and environmental risk group.
The environmental risk grouping of herbicides is what the LERAP scheme is part of. Herbicides are broken down in to 2 Categories.
Category A herbicides cannot be used in sensitive environments where they may be caused to enter a 'Watercourse'. (This is any area that normally carries or holds water such as a stream or pond; plus any area likely to carry or hold water under foreseeable normal conditions.)
Category B herbicides are licensed for use in the sensitive environments around watercourses, but application licenses must also be held that demonstrate a proper level of professional training in assessing the risk to the environment to use them. This is indicated by the 'w' on a license.
