A sedum roof collects leaves, twigs and other organic material. This can disrupt the growth of the sedum. A built-up layer of leaves means the plants don’t get enough light and air. That’s why it’s important to clean your roof twice a year.
Both in spring (March – April) and in autumn (September – October), it’s best to remove leaves, branches and any dead plant debris. Use a leaf blower on a low setting or a soft brush to remove dirt without damaging the plants.
Tip: Do you notice bare patches during maintenance? No problem: you can easily fix this yourself by trimming back plants that have grown too long and scattering these cuttings over the bare patches to fill them in again.

Although sedum roofs are naturally low in weeds, unwanted plants or moss can sometimes still grow, especially in the first years after installation.
Tip: Avoid chemical weedkillers; they can damage the sedum and disrupt the ecosystem.

A green roof buffers rainwater, but it’s important that excess water can drain away properly. Therefore, regularly check that the drainage outlets or gutters are not blocked by dirt, leaves or moss.
Tip: Good drainage prevents overloading the roof and protects the roof structure against moisture damage.

Sedum plants are low-maintenance, but for healthy growth and strong roots they occasionally need extra nutrition. The substrate layer is relatively thin and contains few nutrients. During heavy rain, excess water is drained away, and the nutrients are washed away with it. Therefore, fertilise your green roof at least once a year, preferably in spring (March–April). Ideally, repeat this fertilisation in autumn (September) to ensure your green roof is prepared for extreme temperatures and stays nicely full.
Tip: Fertilisation helps the sedum stay dense and strong, reducing the chance of weeds and moss.

Sedum roofs can cope well with drought, especially once the sedum mat is well rooted and fully established. Normally, extra watering isn’t necessary because sedum stores water in its leaves. However, during extreme heat and long periods without rain (4+ weeks) extra watering may be required.
Tip: Have you noticed the sedum turning red or purple? That’s a sign of drought stress, so your plants could do with some extra watering. In autumn the sedum will also turn red; that’s a normal process and doesn’t indicate a lack of water.
