Pruning Cast Iron Plants: How To Prune Aspidistra Plants

Aspidistra elatior, aka Cast Iron Plant, is a hardy perennial foliage plant from China.

When any of the cast iron varieties are kept as houseplants, the plants can benefit from a good pruning every few years, in the springtime.

Aspidistra kept outdoors or planted in the landscape may need more frequent trimming because of damage caused by the elements and sometimes by deer.

In between thorough prunings, do the following:

  • Trim away dead or damaged leaves or leaves that interfere with the plant’s appearance.
  • Whenever you prune a Cast Iron Plant, you should trim the stems as close to the surface of the soil as possible.
  • Then, remove the entire leaf and stem.
  • If leaves are completely brown, you can pull them off.

How Do You Prune A Cast Iron Plant?

As with any garden task, begin by gathering the materials you’ll need.

  • Garden gloves or rubber gloves
  • Very sharp pruning shears
  • A bottle of bleach
  • A bucket
  • Water

Step 1:

In your bucket, combine bleach and water at a ratio of 1 part bleach and 9 parts water.

You’ll use this to sterilize your shears before you begin pruning your Cast Iron Plant.

If you are pruning more than one plant, sterilize your shears between plants.

Step 2:

With your gloves on, pull off any leaves and stems that are completely dead and brown.

Step 3:

Use your shears to completely prune away leaves, stems, and branches showing any damage signs.

If a leaf has brown tips, it will not get any better.

Cut the leaf back all the way to the soil to enable the plant to use its energy to create new leaves.

Step 4:

Shape the plant and improve air circulation among the leaves by trimming away any branches that may criss-cross in the center of the plant.

Step 5:

If the plant is taller or larger than you want, cut away the tallest branches.

Perform this sort of thorough pruning once a year, when the plant is poised to put out new growth in the springtime.

Cutting away damaged, dead and diseased limbs, stems, and leaves encourage lots of lush, new growth.
