The evergreen giraffe grass bag method: You will understand the reasons for 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 previously referred to as abnormal weather, are starting to become commonplace. The plants used in the thin-layer rooftop greening until now have primarily 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. Previous rooftop greening systems were complex and could only be handled by specialized contractors. 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 needed The Evergreen Kiri-sou Bag Method is a new greening approach that puts specialized soil for evergreen Kiri-sou into bags, achieving "soil erosion prevention," "weed control," and "easy greening." Search for "Rooftop Greening Revolution" on YouTube to find videos of soil erosion experiments. You can navigate to the video page through the related links below.

This bag method (Patent No. 4911418 + Registered Trademark No. 6125712) combined with variety registration (Variety Registration No. 15866) is a triple intellectual property product. The triple intellectual property of the evergreen sedum bag method (patent, trademark, variety registration) leads to successful rooftop greening. 1. Prevents the intrusion of weeds 2. Prevents soil runoff 3. Easy installation with a zipper The standard size of the bag method is 50 cm square, with a wet weight of 13 kg per bag. There is also a rectangular type measuring 15 cm x 100 cm available. Grommet options and custom sizes are possible. The rectangular type is used for wall greening and folded plate roof greening. The bag material is made of root barrier sheet, which stops the intrusion of weeds and prevents soil scattering and runoff. The bag allows the evergreen sedum to provide moisture to the soil while simultaneously preventing soil drying. The site will receive bags filled with soil and seedlings of evergreen sedum, so you simply open the zipper of the bag, insert the seedlings, and close the zipper. This is a simple greening system where just arranging the bags with plants completes the greening.

Causes of Rooftop Greening Failures: Abnormal Weather In Japan, there have been many occurrences of damage from typhoons, heavy rain, floods, and landslides in 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. Moreover, not only the rise in temperature but also extreme drops in temperature during winter have been seen as one of the abnormal weather patterns in recent years. Amidst the increase in such weather phenomena, various problems have arisen in rooftop greening as well.

Causes of Rooftop Greening Failures: Selection of Plants Unsuitable for Rooftop Environments The temperature in Japan has been rising year by year, with particularly abnormal high temperatures often observed during the summer and autumn. Additionally, not only is there a rise in temperature, 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 necessary.

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 by wind, leading to an overgrowth of weeds without notice. Special care is needed for the greening of roofs in factories where people do not enter.

Causes of Rooftop Greening Failure: Maintenance Issues in Rooftop Greening Systems One of the causes of rooftop greening failure is "maintenance issues." Rooftop greening is not maintenance-free. There are various tasks involved, such as weeding, pruning plants, watering, and cleaning around drains. Initially, it is manageable, but over time, due to reasons like becoming troublesome or labor-intensive, 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 particularly critical for corporate rooftop greening, where the irrigation system may fail during summer vacations when no one is present, leading to the complete loss of the greening after the holiday. Just having an automatic irrigation system does not guarantee safety. 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 Renovations (Waterproofing Renovations) When performing waterproofing renovations, it is necessary to remove the rooftop greening. This removal of rooftop greening becomes a very challenging task. The soil removal work requires a lot of effort, and there are also issues with 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 the rooftop greening, there may be cases where reuse is not possible, so caution is necessary. It is also essential to consider rooftop greening options that make 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, extreme weather events have increased, with "heavy rain" exceeding 80 mm per hour rising by about 1.7 times in the last 30 years. Such intense rainfall can wash away the soil and plants in rooftop greening, leading to issues like clogged drainage systems. Additionally, recent typhoons have become more powerful, necessitating consideration of wind scattering as well.

Soil Erosion Experiment One of the reasons for the failure of rooftop greening is "soil erosion." We recreated heavy rain by bursting large water balloons and conducted an erosion experiment comparing the rooftop greening systems "bag method vs. conventional method." Recently, abnormal weather has increased, and the amount of rainfall exceeding 80 mm per hour, referred to as "intense rain," has increased by about 1.7 times over the past 30 years. Such heavy rain can wash away the soil and plants of rooftop greening, causing issues like clogging drainage systems.

Soil Dispersal Experiment One of the causes of rooftop greening failures is "soil dispersal." We conducted a dispersal experiment comparing the rooftop greening system "bag method vs. conventional method" by creating strong winds using a blower and a circulator. Recently, it has been predicted that there is a trend of increasing occurrences of very strong tropical cyclones with maximum wind speeds exceeding 45 m/s due to abnormal weather. In such severe weather, the soil and plants from rooftop greening can disperse and cause problems 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, leading to "co-creation" and "hope." In April 2007, at an exhibition, a project team was born. They wanted to create new solutions originating from the field to solve customers' problems. Three professionals who shared such passionate thoughts met, and the Evergreen Kiri-Sou Promotion Association was established. Professionals in plants, architecture, civil engineering, and facilities breathe new life into the city. Moments of inspiration are continuous. The opportunities to experience moments where the heartbeat never stops are becoming fewer. Why is that? Perhaps it is because of the increase in fakes and deceptions. We aim to remain professionals involved in plants, architecture, civil engineering, and facilities, 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.
