The evergreen giraffe grass bag method helps identify the causes of failure in rooftop greening!
There are solutions to the causes of plant selection mistakes, rampant weeds, soil erosion, and failures in rooftop greening.
**The Rooftop Greening Revolution Begins** Recently, phenomena such as heavy rain and strong winds, which were once referred to as abnormal weather, are starting to become commonplace. The plants used in traditional thin-layer rooftop greening have mainly been sedums, but they are declining due to the recent weather conditions. Additionally, soil is being washed away by heavy rain and strong winds, leading to overgrowth of weeds. **Causes of Rooftop Greening Failures** Please see the detailed information below. Until now, rooftop greening has involved many complex systems that only specialized contractors could implement. The rooftop greening revolution aims to break away from these existing methods and maintain a green oasis easily and sustainably. The system that has made this rooftop greening revolution possible is the "Evergreen Kiri-Sou Bag Method®," which ensures successful rooftop greening. **Features of the Evergreen Kiri-Sou Bag Method** ■ Soil erosion prevention ■ Weed control ■ Easy greening ■ Low maintenance ■ No watering required The Evergreen Kiri-Sou Bag Method is a new greening approach that places specialized soil for evergreen Kiri-Sou in bags, achieving "soil erosion prevention," "weed control," and "easy greening."

Causes of Rooftop Greening Failures: Abnormal Weather In Japan, there have been many instances of damage from typhoons, heavy rain, floods, and landslides across various regions. Additionally, in recent years, there have been widespread heatwaves. In fact, Japan's temperatures have been rising year by year, with particularly abnormal high temperatures observed during the summer and autumn. Furthermore, not only the rise in temperature but also the extreme drops in temperature during winter are among the abnormal weather phenomena seen in recent years. Amidst the increase in such weather events, various problems have also arisen in rooftop greening.

Causes of Rooftop Greening Failures: Selection of Plants Unsuitable for Rooftop Environments Japan's temperatures have been rising year by year, with particularly abnormal high temperatures observed during the summer and autumn. Additionally, not only is there a rise in temperatures, but extreme cold and heavy snowfall in winter have also been seen in recent years. As such, rooftops are increasingly exposed to harsh environments, making the selection of appropriate plants essential.

Causes of Rooftop Greening Failures: The Weed Problem in Rooftop Greening Systems One of the causes of rooftop greening failures is the "weed problem." Typically, rooftop greening systems have soil exposed on the surface, allowing weed seeds to enter from the surrounding environment, through animals bringing in seeds, or being carried by the wind, which can lead to an overgrowth of weeds without notice. Special care is needed for greening roofs of factories that are not accessed by people.

Causes of Rooftop Greening Failures: Maintenance Issues in Rooftop Greening Systems One of the causes of rooftop greening failures is "maintenance issues." Rooftop greening is not maintenance-free. There are various tasks such as weeding, pruning plants, watering, and cleaning around drains. Initially, it is manageable, but over time, due to reasons like becoming cumbersome or troublesome, it is often neglected and becomes overgrown. It is necessary to consider the introduction of rooftop greening systems that take maintenance into account.

Causes of Rooftop Greening Failures: Malfunction of Irrigation Systems in Rooftop Greening Systems One of the causes of rooftop greening failures is the "malfunction of irrigation systems." To reduce the hassle of watering, automatic irrigation systems are introduced, but it is important to keep in mind that malfunctions can occur. This is especially true for corporate rooftop greening, where the irrigation system may fail during summer vacations when no one is present, leading to the complete destruction of the greening area upon return. Just having an automatic irrigation system does not guarantee peace of mind. When considering rooftop greening, it is also necessary to explore systems that do not require watering.

Causes of Rooftop Greening Failures: The Difficulty of Rooftop Greening Renovation (Waterproofing Renovation) When performing waterproofing renovations, it is necessary to remove the rooftop greening. This removal of rooftop greening is a very challenging task. The removal of soil requires a lot of effort and also raises issues related to dirt. Additionally, in the case of tray systems, they are securely fixed (with bolts or adhesive) to prevent scattering. This dismantling work becomes very labor-intensive. Furthermore, when restoring rooftop greening, there may be cases where reuse is not possible, so caution is essential. It is also necessary to consider rooftop greening that makes waterproofing renovations easier.

Causes of Rooftop Greening Failures: Soil Erosion Issues in Rooftop Greening Systems One of the causes of rooftop greening failures is "soil erosion and scattering." Recently, abnormal weather has increased, and the occurrence of "intense rain" with rainfall exceeding 80 mm per hour has risen by about 1.7 times in the last 30 years. Such heavy rain can wash away the soil and plants in rooftop greening, causing issues like clogged drainage systems. Additionally, recent typhoons have become more powerful, necessitating consideration of scattering due to wind.

Soil Erosion Experiment One of the reasons for the failure of rooftop greening is "soil erosion." We recreated heavy rainfall by bursting large water balloons and conducted an erosion experiment comparing the "bag method vs. traditional method" of rooftop greening systems. Recently, extreme weather events have increased, with "intense rain" of over 80 mm per hour rising by about 1.7 times in the last 30 years. Such heavy rain can wash away the soil and plants of rooftop greening, causing issues like clogged drainage systems.

Soil Dispersal Experiment One of the reasons for the failure of rooftop greening is "soil dispersal." We conducted a dispersal experiment comparing the rooftop greening system "bag method vs. conventional method" by creating strong winds with a blower and a circulator. Recently, it has been predicted that there is an increasing trend in the occurrence of very strong tropical cyclones, with maximum wind speeds over 45 m/s, due to the rise in abnormal weather. In such severe weather, the soil and plants from rooftop greening can be dispersed, causing issues such as clogging drainage systems.

Company information
In manufacturing, there are people, and in projects, there is drama. The "passion" of three individuals transcends the boundaries of the company to create "co-creation" and "hope." In April 2007, at an exhibition, a certain project team was born. They wanted to create new solutions originating from the field to solve customer problems. Three professionals who shared such a passionate desire met, leading to the establishment of the Evergreen Kiri-Sou Promotion Association. Professionals in plants, architecture, civil engineering, and equipment breathe new life into the city. A series of moving moments. The opportunities to experience moments where the heartbeat never stops are becoming fewer. Why is that? Perhaps it is because the number of fakes and forgeries has increased. We aim to continue being professionals involved in plants, architecture, civil engineering, and equipment, and we operate the Evergreen Kiri-Sou Promotion Association. The professionals have developed new greening methods and greening systems. That is the Evergreen Kiri-Sou bag method.
