However, the exact length of time it takes for your beautifully unique orange and brown hues to appear depends on a variety of factors, such as local climate and your exact planter placement. If you are particularly close to the coast, for example, sea spray and salty air could cause your planters to rust faster (which is why we recommend choosing sheltered locations for such instances, in addition to potentially hosing your planters down after strong coastal storms).
