Tips For Choosing Plants For Your Green Roof

Green roofs are becoming increasingly popular as more people and companies discover that they can help reduce heating and cooling bills, as well as improve the overall look of the building. Green roofs are also an excellent way for businesses to show the community that they care about the environment and committed to making changes that will decrease the overall amount of carbon dioxide that is in the atmosphere. Here are some tips for choosing the best types of plants for your green roof, should you decide to install one.

1. Choose Plants With Extensive, Spreading Root Systems  

The first thing that you are going to want to look at is the root systems of the plants that you are choosing and to make sure that their root systems are expansive. You want to choose plants that have root systems that expand horizontally, rather than vertically in order to make sure that the roots will adhere the plants securely to your roof so that they can withstand high winds. If you choose plants whose root systems grow downwards, then you risk having plants that are not going to be nearly as healthy if they do not have the room their root systems need. Most green roofs do not have the depth that plants with deep-growing root systems need.

2. Choose Plants That Do Not Grow Very Tall

Next, you are going to want to make sure that you choose plants that do not grow particularly tall. If you choose low-growing plants, you can be sure that you won't violate any zoning issues, as well as ensure that your plants do not grow to the point where they are too heavy for your building's structure to support. Low growing plants will also be able to provide your building with greater insulation levels since the foliage will be more dense nearer to the building.

3. Choose Plants That Can Retain Water

Chances are good that you are going to not have to worry about watering your green roof all the time. As a result, you are going to need to make sure that you choose plants that will be able to store water from rainfall to rainfall and not need to be watered on a regular basis.
