If you’re going to use bleach as part of the cleaning solution, opt for oxygen bleach over chlorine bleach. The former goes easier on foliage. Move as many potted plants as possible out of the immediate area. The plants you can’t move should be hosed down thoroughly with clear water before you start. That’ll naturally dilute any overspray that happens to land on the plants.

Another alternative is to cover your plants with plastic. But it’s important not to cover all the plants at once, especially if you have a large home and it’s a warm day. Prolonged periods shrouded in plastic can smother even the hardiest species. Covering plants becomes essential if you have natural wood siding and plan to use a sealant after power washing. That’s because most sealants can’t be washed off and are lethal to flora.
