I'm picking up some mulberry trees this week/weekend for some of our tortoise enclosures, and have come to this dilemma.... Apparently, the fruitless trees (which I planned on) are illegal to plant in Las Vegas since 1991 due to the allergies they give some people. There's many many of the trees here already, planted in the 50s and 60s, but they don't allow new trees. In my interpretation of the law, the mulberry trees that produce fruit are not illegal, but people don't typically use them because their fruit was staining driveways and cars parked underneath them. If I was planting these in an area several hundred feet away from my eventual house, does anyone here with a fruiting mulberry tree see this being a problem (some of the fruit dropping into the tortoise pens for about 1 month of the year)? These would be younger trees; 8-10' height. I don't really need the lecture about "not feeding fruit to tortoises," I am looking for someone with this situation and if you think it'd truly matter. Any input is appreciated!
