Retaining rainwater for plants and trees

Healthy cities need healthy trees and plants

Climate change brings extreme weather conditions: droughts and downpours alternate. This poses a major challenge for our plants and trees in urban areas. Urban greenery withers particularly during hot spells. This restricts plant growth and flowering periods, and therefore has a direct impact on a city’s resilience to heat. Without healthy trees and plants, there is no shade, no cooling and no biodiversity.

However, maintaining and watering urban greenery is costly and requires a large amount of water and energy. This includes the use of water tankers, staff and pumping systems.

So how can we keep trees and plants in the city green and healthy in an efficient way?

Rockflow® FloraSponge: rainwater as a local water source

Rockflow® FloraSponge is an innovative stone wool solution that retains rainwater exactly where your plants need it. The product acts as a natural water reservoir for rainwater and automatically releases water to the plants when they need it.

The secret lies in the capillary properties of stone wool: up to 95% of its volume consists of hollow spaces that store water at high speed. At the same time, the dense fibre structure ensures that water does not simply run off, but remains temporarily available for plant roots.

The result? Plants grow better, blossom longer and can withstand drought for longer without additional irrigation.

With a consistent water supply, plants grow faster and bloom longer. Plants provide a habitat for insects and birds and help to keep the area cooler on hot days.

Rockflow® FloraSponge eliminates the need for expensive irrigation infrastructure and reduces water consumption by passively retaining water and gradually releasing it to plants, resulting in significant savings on energy, labour and maintenance costs. Healthier plants also require less care, need fewer treatments for disease and have a longer lifespan.

Rockflow® FloraSponge fits into any green strategy, from small to large, from fixed to mobile. Whether you want to upgrade a single planting container or transform an entire square: this stone wool solution offers freedom and flexibility without the need for complex engineering.

With Rockflow® FloraSponge, you can achieve climate adaptation and sustainability goals: local water retention, improved groundwater balance and increased biodiversity.
