A common misconception of landscapers is that they only do big projects - designing a new garden and implementing it for you or with your help. But commonly landscaping companies offer a range of services. Some landscaping businesses also specialise in a specific area.
The range of services offered by landscapers
A design landscaper will look at your garden, your home, and design a new landscape to suit your soil, gradient and style of home. They can include anything from water features to retaining walls to imported plants to new gates to a pergola, and work to your requirements and budget. They'll draw you pictures and plot out plant locations (planning for the initial planting as well as longer term visual impacts). Once they're done the landscape 'architecture' you'll be able to choose whether to follow the plan and DIY, or hire that company or another to complete the work.
This is the implementation of a designed plan - including decking, pergolas, planting and irrigation, depending on what your plan is. This can be a tiny job or a massive job, can involve supplying plants or materials or letting you choose and then planting them. Some landscapers will work together with gardeners to complete this part of the job, allowing them to focus on the construction of retaining walls or pergolas.
Garden paths or paved eating area, with or without railings, stairs, concrete or tiled - landscapers can do it all. Paths and paving areas are a great way to break up a boring garden as well as reducing wear and tear on well trodden routes.
You don't need to have a sloped garden to build a retaining wall, but goodness do they help keep your garden organised when you do have a slope! Landscapers will both build retaining walls and do any earthmoving necessary to create a 'stepped' look. A flat garden can be accentuated with retaining walls around raised garden beds (which is also great for protecting your herbs from children's feet and animals).
A landscaper also supplies and fits shade structures, including sails, screens, lattice work and vertical screens. Need to keep part of your garden shady for a small veg patch - lattice work with creepers is a aesthetic and organic way to keep the sun off.
From installing a bird bath to a larger scale fish pond or water feature, your landscaper can help. Occasionally a licensed plumber will also be needed but if so, your landscaper can organise this for you. Some landscapers also specialise in designing structures around water tanks to disguise their function and make them look less ugly.
Landscapers are the kings of the garden trades
A landscaper will often have a wide network of trades that they occasionally work with such as tree loppers, fence builders and swimming pool installers. They are almost the 'king of trades' in the same way as a builder is, who can organise everything to do with building but will only usually do the actual building work. If you're looking for a variety of things to be done (or simply design) then a landscaper is what you want, whereas if you're specifically interested in only that particular trade (ie a new swimming pool, fence or tree lopping) it's usually best to look for what you want even though a landscaper can often organise this for you.
