Other Comments:
Our carpenter is building a tree fort around it and did not realize cutting a major root 14″ – 16″ around? could kill the tree. We are devastated and wonder if there is anything we can do now to save it? Can we treat the root and seal it? should we water it? compost around it? We cannot find an arborist here in Nairobi.
Thank you so much for any help.
Kindly, Olivia

Hi Olivia, The tree should be OK. Do not seal the root, do not add compost nearby. YES do water it: use a sprinkler for at least 1 hour once a week in the entire area under the canopy. Maybe this will be a diameter of 15 metres or more. Also get some liquid seaweed product like Seasol Super Soil Wetter and water this in each month. If you can’t get Seasol get any liquid seaweed product and also use a soil wetting agent. Good luck, Don.
