Concerning weed removal (ep. 71), apart from chemical solutions, there are portable flamethrowers for removing weed (I think they are officially called weed torches). They are quite efficient, plus using a flamethrower is a lot more fun than mixing salt, vinegar and whatever else trying to poison the ground. One exception are deep rooted unwanted plans like thistles though - these have to be rooted out. But check if flamethrowers are allowed on Ibiza at all (fire hazard).
A question to both of you for the podcast: Well into the 3rd month of your Ibiza residency, which aspect of life in Dubai (if any) are you missing the most on Ibiza?
