This is sad...I'm Half Yemeni/ half East African...on behalf of these crazy people I apologize, they should know better!! Braking into someone's property is absolutely wrong.
I was born and raised here, so I have not been exposed to this khat culture, in Recent months I started looking into this plant!!...the problem is the Africans here don't know how to go about growing their own trees/ majority of them don't own properties..
My grandfather's family have been growing khat in Yemen for centuries!!..unfortunately he passed away when I was a baby and the entire family migrated to Europe and other parts of the world.
Good to see Australians interested in this plant and would like learn from one another. I'm in Melbourne I've read that it's difficult to grow due to the weather here, PM if your growing some would enjoy learning from you.
Cheers
