The design of terrace garden needs openness and lighting: The terrace garden needs to be kept as open as possible, and closed designs, such as glass or colored steel tiles, should be avoided, because the growth of plants needs sufficient sunshine, circulating air and rain. At the same time, it is necessary to ensure good lighting in the terrace garden, so as to enjoy the scenery and carry out various activities.

Area and layout: According to the area and shape of the terrace, you can choose to plant plants of different sizes to create a garden feeling. If the terrace area is small, you can also use small shrubs or potted plants. At the same time, it is necessary to rationally plan the layout, including rest area, operation area and flower border, so as to make the space more comfortable and practical.

Waterproofing and root blocking: Waterproofing and root blocking of terrace gardens are very important, because terraces are often eroded by rain and plant roots. Therefore, when decorating the terrace garden, it is necessary to choose materials with good waterproof performance, such as waterproof coating and waterproof coiled material, and make the bottom waterproof. At the same time, in order to prevent plant roots from damaging the roof, it is necessary to choose materials with good root resistance.

Plant selection and collocation: When selecting plants in terrace garden, factors such as plant growth habit, light demand, color collocation and viewing season should be considered. At the same time, we should pay attention to the diversity and layering of plants to make the garden more colorful.

Decoration and lighting: In order to make the terrace garden more beautiful and practical, you can add some decorations and lighting. For example, some decorations such as sculptures and fish ponds can be designed to increase the visual effect. At the same time, in order to facilitate the use at night, you can add some lighting to improve safety.

In short, the design of terrace garden needs to be customized according to personal preferences and needs. In the design, we need to pay attention to the factors such as openness and lighting, area and layout, waterproof and root resistance, plant selection and collocation, decoration and lighting. Only by comprehensively considering these factors can we create a comfortable, beautiful and practical terrace garden.
