I put up a vertical gardening rack to save space and grow tomatoes on my balcony. A strong wind last week sent it crashing down, ruining all my plants. Is vertical gardening really safe for exposed balconies, or should we stick to heavier pots?
That's a real shame about your tomatoes... see this all the time with DIY projects. People focus on the cool part and skip the basic safety steps... wind doesn't forgive.
Wait, didn't I see a video where someone filled old plastic bottles with sand and put them in the bottom of their pots for extra weight? It seems like a cheap fix if you don't want to drill into your railing. But you're totally right, if the whole thing isn't tied down, a strong gust just takes it all. I guess it's one of those things you don't think about until you're picking dirt and plants off the sidewalk.
