Tree Aftercare Assistant 

"[Aftercare allows me to] get to be involved doing the work that I am good at and that I enjoy. I have an opportunity to include my children, we can be outside and I can teach them the importance of giving back to our community." ~ Craig Ingram

Keeping the Forest in the Forest City takes more than tree planting alone.

Caring for trees during their first few years is essential to the success of a naturalization project, and ReForest London needs your help! As a Tree Aftercare Assistant, you'll help ensure the survival and health of our newly planted trees. This involves maintaining an optimal growing environment for them, as well as providing protection from harmful weeds and animal pests. Our Tree Specialists will help you to identify the weeds that need to be removed around the trees, as well as identifying which grasses need to be covered in mulch around the trees so that they can retain moisture.

If your group is larger than 10 people, please see our Group Volunteering page.


  • Weeding
    We focus on the grass and weed competition growing in the old mulch circle of each tree. We provide tools to help with this process, but most weeding can be done by hand.
  • Mulching
    At least one bucket of mulch will be spread on each tree and shrub after it has been weeded. Mulch keeps moisture in the ground to help protect trees from drought, as well as suppresses further weed growth.
  • Checking Tree Collars
    Tree collars are used to protect the trunks of young trees from animal browse. Most of the time, all trees will have collars from when they were planted, and collars will only need to be fixed. Sometimes new collars will be need to be put on, taken off, or cut to a more appropriate size.
  • Invasive Species Removal
    To enhance our park naturalization sites, we will remove certain invasive weeds and shrubs, such as European Buckthorn.
  • Applying Skoot
    Scoot is a pest deterrent that is applied to the bark of the tree trunks and some of the branches each season. Scoot is painted on using a paint brush, and only used on sites where we have observed animal browse.
  • Pruning
    Branches that are vandalised, dead, or affected by animal browse will be pruned so that fungus and disease do not establish.
  • Litter Clean Up
    This is a lower priority but will be done on sites where a lot of litter is present.

Events are typically 1.5-2 hours long on weeknights or Saturday mornings during summer months of July and August.
