Won’t the pressure be too low if I’m watering my perennials with a hose connected to a rain barrel?
The pressure will be less than what you get from a traditional tap water spigot, so “overspraying” your plants will be difficult. To water perennials, place the end of the hose at the base of the flower bed. Move the end of the hose every few minutes to reach different areas within the bed. Also don’t forget that raising your rain barrel by placing it on a STURDY platform will increase the rate of flow.
