Upside down tomato

We have planted our upside down tomato.  We’ve also planted some toma­toes in the usual direc­tion, but I am most curi­ous to see how the Topsy Turvy planter fares.  The idea is this: you plant your flower, veg­etable, or what­ever, in this vinyl bag, and hang it from some­thing tall.

Until about a month ago, we had noth­ing tall enough or sunny enough to do it.  Then my father in law built the tree house, com­plete with pro­trud­ing spar (where the swing was going to go).  And now we have a spot.  Not sure if it is tall enough, given how tall tomato plants get, and this one won’t be act­ing against gravity.

If need be, we can always throw a rope over a tall branch and string it up that way.

Any­body had any luck with these Topsy Turvy planters?
