Date of Visit: June, 14, 2011
Present: Christopher Campbell, Karen Wan-Gauthier
Weather: Slightly overcast with sunny breaks
Photos taken: Yes
Months since installation: 1 year
Very good overall vegetation coverage of predominantly reddish seedum; very spongy and thick with nice root structure. There were lots of maple seedlings taking root (see pictures above), some with a very long tap root. Very little grass weeds were observed. Because this roof is sloped there was a little more concentrated growth in the down-slope corners and less new growth in the center. Overall observation is that the roof is very healthy with nice shade cover and afternoon sun.
- S. sexangulare, S. acre and S. album were the pre-dominant species
- S. album observed were red-green
- Some sedum was observed to be flowering
- Some small bare spots remain
- No exposed polymer coils were observed
Slight overgrowth of sedums were found in the rock ballast border edge.
2. Actions Taken:
- Cleared debris
- Removed all weeds by hand
- Cleared overgrown vegetation in the non-vegetated border
- Collected sedum cuttings from overgrown areas and scattered on the bare areas
- Watered and applied slow release fertilizer
3. Action Recommendations:
Verify sedum growth on dry patches. During the summer hot periods watering once or twice a week is recommended. Regular yearly maintenance schedule of 2 to 4 visits.
4. Next maintenance visits:
To be determined by client.
