Best railing planters for balconies: no-drill picks by railing type
Round, square, wide-top or no-drill. Rated for wind, weight and whether your landlord will notice.
Three numbers decide what a balcony can grow: the hours of direct sun it gets, how much weight the floor will take, and how exposed it is to wind. Count the first, assume about 50 lb per square foot for the second unless your building says otherwise, and take the third seriously — wind dries pots faster than sun and flattens anything trellised above three feet.
After that it's a renting problem as much as a gardening one. Nothing needs to be screwed into a railing, nothing should drain onto the balcony below, and everything should come off in an afternoon when the lease ends. The guides below are all built to that standard.
