Eucalyptus and Nothing Grows?!
A recent phone conversation between myself and an old friend touched on Eucalyptus Trees and how due to something the tree exudes, nothing will grow within a certain distance from the tree.
Now I don't thing that 'nothing' is the last word here, but apparently, a lot of things won't grow and I'm very curious to know more about this as Eucalyptus are a member of the 'Myrtle' family and I have many Crepe Myrtles growing around here and I've already found from surfing the web, that Crepe Myrtles also exude oils, but thusfar have found no mention of properties of those oils that would stymie or inhibit the growth of other plants.
I was told that once you have a Eucalyptus, the ground remains toxic for quite some time and the only thing that can be done is to actually replace the soil?!!!
So questions, questions, questions ....
1) What Will grown under Eucalyptus?
2) What is the substance and what is its lifetime in the soil?
3) Do Crepe Myrtles exude this substance?
