The basic landscaping ideas guidelines
Unified Landscaping Material
Unifying the various landscaping materials is quite essential with a well-planned layout Avoid planting too many distinctive areas that will then need to be tied together. The more parts you break your garden into, the harder will be to unify them.
Balance, and not symmetry, lies in creating the same visual weight on either side of a central point of interest. The weight need not be mass, instead it can be color or even a form. One needs to visualize the entire area and divide it in two and if both the sides attract equally then the landscape is balanced.
Proportion forms yet another basic guideline for landscaping. Choose plants and garden structures that are in scale with the architectural lines of your home.
Variety is related to surprise. It also helps to lessen the monotony that may result due to unity.
