Planting Spirea In Hard Clay

Question

Our soil is extremely hard clay. Doesn’t drain well. It is difficult to amend a large area of soil, due to underground utilities and irrigation. Can we grow them in raised beds, and if so, how deep mut the raised bed be. Thank you

Answer 1

You can grow them in large containers or in raised beds. You can also create a berm, or slight hill, to plant them. Here is more:
