Maintenance

Maintenance of sedum green roofs is minimal.  One or two visits by an appropriate labour force may be needed in the first year just to check on any plants they may need replacing or applying any nutrients in the green roof system.  On the whole sedum maintenance is minimal and every so many years a “trim” may be necessary.  The cuttings can be left as these will root again and thicken the matting.  Sedum Green Roof will offer a maintenance contract if required. This will be priced according to the size and accessibility.  Our team can discuss with you in detail your sedum maintenance requirements, just contact us.

If you require special designs or certain species please contact us.  Be prepared that specially designed sedum mats will take between six and nine months before they can be rolled and transported. We have a plentiful stock of our basic sedum mats, which include approximately six to seven different varieties of sedum. We also now have our new Modular System the S.Pod or Sedum Green Tray. These are much easier to lay and do not require all the layers as they are incorporated into the trays.

Basic Installation Maintenance

In common with ground level planting green roofs require some maintenance to ensure that the original species selected establish and thrive.  This is usually only necessary in the first year of laying.  We recommend that in this period of the first 12 months a maintenance visit consisting of two visits followed by a minimum of one further visit per year after the first year will give optimum satisfaction.

Typical procedures carried out during maintenance contracts are as follows:

  1. Removal of unwanted plant material, ie grasses etc.
  2. Correction of any localised plant system problems that may have occurred post installation.
  3. Replacement of any naturally failed plants not exceeding 5% of total plants installed.
  4. Application of nutrient source.
  5. Removal of dead flower heads (if required).
  6. Inspection of rainwater outlet chambers and surrounding vegetation breaks.
  7. Replenishment of any areas of settled substrate.

What happens if your green roof does not look as great as you would want?  What should it look like at different times of the year?

Green roof substrates can sometimes have problems retaining the plant nutrients, especially if it has been a very wet season. If your flowers have been in short supply then it may be time to think of giving some sort of fertilizer. If on the other hand you have had an abundance of flowers, then it may be that the plants are heading for exhaustion and may need a pick me up ready for the winter.  Too much rain or cold conditions can cause the Sedum to change colours, red often shows a sign of going dormant, this is often seen during the winter months. It is often a good guide to feed your Sedum roof once a year, perhaps twice if it is high rainfall. The best feed is a nutrifusion spring and summer feed at a rate of 30g/m2 any time between the beginning of March and the end of September.  Contact us for any advice. We can chat with you if you are at all worried about your Sedum Green Roof.  We do not have to have supplied your Green roof to give you advice.


We find that selling on line can get confusing and many people make mistakes.  Just ring us and we will advise the exact quantities you need to obtain your perfect green roof.
