Then stick the cutting in moist potting mix and cover it with a plastic bag to trap as much humidity as possible. The depth of the cuttings is about 1/3 to 1/2 of the spike length. Keep the bagged cutting in a bright, warm spot and give it a gentle tug every few weeks to see if it is rooting. As soon as the cutting roots and begins to grow, pinch the tip to encourage good branching. When it grows out of the root system, it can be transplanted with soil mass on the pot.

  • You can prune China doll plant creatively to encourage the look you want. For more thickness, trim stems that point inward so they will branch and fill in the space. Cut back errant, outward-growing branches. or, if you want a more open style, cut back the inner-facing stems instead.
  • Often you'll notice one stem feels the need to sprint ahead and dominate the others – simply trim back each new growth spurt.
  • Monitor the soil closely after a major trim, because the loss of foliage can result in less water use.
  • If the new branch is growing really fast, cut off about a third of the top. This has the advantage of removing the tips of the plants, supplying nutrients to the entire China doll plant, and encouraging the lateral buds below to bud.
