I imagine you could pick a few of the fruits and dig out the seeds and dry them and plant them next year. The link said they were edible too. I wonder what they taste like.
As for keeping the kids off the roof, is there any way you could put a gate up to block off the alleyway between the buildings? I’ve seen them do that in the downtown areas around here. The little alleys are just barely wider than a standard door and the nicer gates are made of ornamental iron.
I was wondering about seeds inside the fruit.
I asked Larry before about putting gates across the alley and he said he didn’t think we could because it would be a fire escape lane.
