There are many adequate types of Florida green roof plant root structures. The variables different structures become a part of include;
1. Hurricane, tropical storm and wind resistance,
2. Rainfall and water absorption,
3. Plant support,
4. System cohesiveness, and
5. other factors.
One of the major advantages of using a mat with a weave, or trays with an inserted weave for roots to grow into is the overall imparted strength of the system.
Laterally growing roots will provide greater anchoring during high winds. This can be an important factor when considering placing a green roof here in Florida - or anywhere with potential for tropical storms and high winds.
|Florida Green Roof Plant - Good Root Architecture - Lateral Growth|
Roofs are harsh places for plants to survive! Remember the 5 H's - High desiccating winds, High heat, Hard Freezes, HOT-HOT-HOT!, High humidity, Hurricanes, and more...
Lateral root growth contributes towards support, enhanced water absorption area, anchoring and a host of other success factors.
Happy Green Roofing!
