- 1). Cut back the stems to 1 inch tall in the fall before the first hard freeze. Measure out 6 inches from the edge all around the root ball and draw a circle around the entire plant with paint, chalk or simply by drawing a line in the soil with a stick.
- 2). Unroll your 1-foot tall fencing and install it on the marked line all the way around the plant. Trim any extra and secure the ends together with utility ties or twist ties.
- 3). Cover the cut stems with leaves or pine straw halfway up the fencing. Watering it well compact the mulch. Fill to the top of the fencing and water again. Let the leaves settle overnight. Repeat the process until compacted mulch reaches the top of the fencing. If you have a long row of Kopper King, install the fencing around the entire row and fill it with mulch.
- 4). Remove the protective mulch in the spring when all frost danger is over. Be patient because hardy hibiscus may not emerge from the ground until May in colder climates.
