I have some narrow, deep planters on my balcony. I’ve planted some tall decorative grasses in them for some privacy, and they’re great. But now that they’re bigger, they’re falling over and getting in the way. I’ve resorted to just feeding them through the top of the balcony railing, but I don’t love the look.
What’s the most natural way to support or tie them off so they’ll stay mostly vertical and out of the way? I suspect they’ll keep growing taller, and I wouldn’t mind the tops spilling over once they’re not directly in my face. My balcony railing has several metal rods running along it that I could maybe use, but can these grasses be made to stand more upright without looking so obviously tied off?
