WORKING AS A GROUNDSMAN OR GARDENER

A groundsman is a person responsible for maintaining landscapes, gardens or sports venues, either for appearance or for the functionality of the area. In some schools and institutions, they are referred to as “horticulturists”.
A groundsman will be required to carry on certain types of responsibilities to improve appearance and maximise the utility of the area.

These tasks may include:

  • planting and/or watering trees and shrubs
  • cut away dead or excess branches from trees or shrubs (pruning/trimming)
  • mowing and cutting lawns
  • responsible for the cleanliness and maintenance of sidewalks, driveways, parking lots, buildings and other public areas
  • installation of water and/or light systems
  • construction and maintenance of fences, terraces, pools, fountains, planters, burial sites and other ground features
  • applying pesticides, herbicides, fertilizers or other chemicals to the soil, weeds, plants, trees and shrubs or any other surface that requires it
  • planting seeds, bulbs, grass, foliage, flowers, trees, shrubs and plants as well as up keeping them by applying mulch, aerating, weeding, grubbing, removing thatch, trimming and picking, including the decoration of the gardens and landscape facilities.

Groundsmen not only follow a site plan created by a landscape architect, but they may also find the possibility of creating their own design and present it as an alternative option, as well as offering service solutions and confidence to companies of all types and sizes to make sure their grounds and it’s appearance will be kept up to the uppermost standards.

Opportunities
Because of the type of work groundsmen are exposed to, they often find themselves spending the majority of their time in outside areas. The kind of work might be part time, full time, contract work, as well as just a temporary seasonal job.

The most common areas include:

  • Sports facilities such as golf courses, tennis courts, soccer/football fields, cricket fields, bowling grounds, athletic racks and swimming pools.
  • Commercial and private sectors such as universities/schools, government buildings, parks and reserves, apartment complexes, farms, cemeteries, malls, private properties/homes or other commercial grounds
  • National parks, gardens and landscaping areas.

Risks and Challenges
Because groundsmen normally work on outdoor environments, they are generally exposed to variations in weather conditions, as well as noise, pollution or risks that may happen on-site. The job can be physically intensive and a groundsman should be able to enjoy working on this type of environment. Ideally, a groundsman should like the type of sport for the field his work is based on.

A good groundsman, therefore, will be capable of achieving a wide variety of physical work as well as a great resistance to prolonged hours of duty. They should be fit and capable of physical acquires such as prolonged standing, sitting and crouching; ability to push, pull and position tools, machinery and construction material; capability to lift heavy loads; they must be able to work on ladders exposed to heights; they should be capable of working on a variety of different surfaces and must be resistant to environmental disparities.

How to become a Groundsman
Many institutions are trying to shift away from pollution and the use of chemicals and are getting more and more inclined towards integrated pest management. A good groundsman will have the qualification, knowledge and experience to carry on these tasks in the most cost effective and efficient manner. For this, among other reasons, it is of great importance for a groundsman to manage certain skills and have a good horticulture understanding, as well as a profound knowledge on pest control, and weed mitigation when working with certain chemicals such as herbicides, pesticides and/or insecticides.

Because of a growing demand for good groundsmen, it is important that they become familiar with machineries and technologies related to the maintenance of grounds in order to carry out projects and to ensure high standards of quality work.

Some of the tools and machinery involved in tasks groundsmen might have to relate to include: axes, lawnmowers, leaf blowers, saws, hammers, hoes, spades, edgers, hoses, sprinklers, shovels, rakes, rotary brushes, hedge clippers, shovels, pruners, shears, and other garden tools, as well as vehicles and empowered equipment such as tractors, snow blowers, twin-axle vehicles, chain saws, electric clippers, sod cutters, edgers and pruning saws.

Therefore, a top groundsman will know how to identify the correct type of tools and/or size acceptability of the machinery to be used in order to complete both large and small scale jobs.

  • You will need to take care to choose the right college for you. Every college offers something different.
  • They all have different tutors, with varying qualifications and experiences. 
  • Some have higher course fees; but that could be because they offer more extensive support; while others may charge less but provide less services. Some may offer different payment plans to others.

The style of teaching and learning; as well as the emphasis upon assessment and the way work is assessed can vary from one college to the next

Horticulture and Horticultural Education in the New Millennium

Comments from Adriana Fraser, Horticultural Tutor, Course Developer and Writer
Courses and qualifications in horticulture are shrinking! Educational Institutions world-wide are narrowing their course base, lowering course content, absorbing horticulture into other (often non-related) departments and offering their students far less in the process. The rationale for this shrinkage is that there is less demand from students for places (because in general) students are not seeing a great future in horticulture. In reality this is a no-win situation; offer less and students will perceive less scope for opportunity. To look at it another way - with fewer courses offered, student interest will also be lowered (especially when they cannot specialize). And once you also lower the actual course content of those left (on offer) you also lower the value of the qualification – especially in the eyes of the industry.

Horticulture is of great economic and social importance globally. It is a considerable contributor to global physical and psychological health - through the constant and reliable supply of safe foods and also through the production of ornamental plants, for social activity and to enhance our environment.
 
With a world that is growing in population and also facing enormous environmental and economic changes, the need for experts in all sectors of horticulture will increase not decrease. The real change is a shift in needs, rather then ‘no need’. Change is actually bringing about newer and broader opportunities for well qualified, general and also specialized horticulturists. This is apart from the fact that current lower graduate output will create a shortage in the future in all sectors including environmental horticulture, crop growing and the nursery trade. This will be a world-wide shortage!
 
Examples of shifts in the industry include:
 In the nursery trade – a greater demand for dry tolerant plants and a greater demand for vegetable seeds and seedlings as people become more interested in growing their own food. Many people want to grow their own produce to help the environment by lowering the ‘food miles’ (if you lower the distance the food travels before it is on your plate – it lowers the negative impact on the environment). They also have a far better understanding of nutrition and the benefits of organically grown produce. This leads us to three areas of opportunity:

  • The supply of dry tolerant plants and also of seeds and seedling.
  • The opportunity to offer services in ‘organic growing’.
  • The opportunity to offer services in developing ‘sustainable gardens’.

Another area of opportunity is the shift in amenity horticulture towards environmental horticulture. As the trend shifts away from traditional gardening - it is moving more towards sustainable gardens and in a borader sense landscapes. The future for people educated in environmental horticulture is therefore very positive. As a tutor and academic working with ACS Distance Education, I am proud to note that ACS has not followed the ‘shrinking’ trend – in fact each year ACS is offering more rather then less. The range of courses on offer (across all industry sectors) is broad - and will remain so. New courses are consistently added  to the curriculum. These, plus existing courses are also under constant review - not to ‘shrink’ them - but to ensure that all ACS courses reflect current industry needs and also meet the demands of the future.

ACS courses also focus on things that really matter ‘on the job’:

They develop a broad capacity to solve problems and adapt to change in the horticulture industry. In other words you are taught to think rather then just to follow orders.
They develop a range of practical skills in areas that are now so overlooked or reduced in many other courses - for example plant identification and the ‘basics’ of horticultural practice.

They help students to become experts who offer a positive contribution to society ie. without plants we would not have life.

I believe that if you study with ACS Distance Education you can grow in the industry!   Adriana Fraser (ACS Academic Officer)
