I have several (like 10) red hibiscus plants along two sides of my house that the former owner left there.

They were horribly ugly and ragged, so I cut them way back and now they are regrowing, but fairly small.

The problem is, red hibiscus is very commonplace here, so I'd rather have a mixture. And I have many other colors of hibiscus that I'm growing in pots.

Someone told me I should graft the other colors of hibiscus onto the existing plants so that I don't have to grow a new root system. But is that a lot of work? I've never done grafting before. Would I pull my hair out trying to learn?

Or is it easier just to dig them up and replace with another color. (if I did this, I'd probably just alternate them and go red, peach, pink, yellow, etc.... or something like that)
