How do we take care of a green roof in the spring? What do we need to pay attention to? Just like other planting in the garden, green roofs also need care; this should be done at least once a year, but twice is recommended—in spring and autumn.
Plants of the genus Sedum, mainly undemanding plants, are used for extensive greening of roofs. Nevertheless, they need regular attention regarding soil moisture, nutrient levels, and weed removal. In the spring—usually in March and April or when there is no more danger of frost, we do the first maintenance to help dormant winter plants in the transition to the summer flowering season.
List of tasks for green roof maintenance:
• Remove all accumulated waste such as leaves, branches, etc.
• Inspect and clean roof drains for smooth water drainage
• Remove all dead stems and other dry plants for better fire safety
• Remove any unwanted plants brought to the roof by wind or birds
• Plants are fertilized with a special fertilizer for green roofs, where the NPK (nitrogen, phosphorus, potassium) ratio should be 5-2-6, lower than most commercial fertilizers. Fertilize only when temperatures are already constantly above 10°C
• Remediate any bare areas – if necessary, you can cut plants from other healthy green roof areas, sprinkle them over the bare area and cover with a thin layer of soil/substrate
After successful attention, you can indulge in the warm spring rays and enjoy the view of your lush green roof.
