Updated: April 6, 2023

If you’re a fan of low-maintenance houseplants, then you’ve probably come across the Cast Iron Plant (Aspidistra elatior). As its name suggests, this plant is practically indestructible and can tolerate neglect and low-light conditions. It’s an excellent choice for those who want to add some greenery to their home without having to spend too much time caring for it.

However, when it comes to planting Cast Iron Plants, one question that often comes up is how much space should be left between each plant. In this article, we’ll explore the answer to this question and provide some additional information on caring for Cast Iron Plants.

How to Plant Cast Iron Plants

Before we dive into the spacing requirements for Cast Iron Plants, let’s first review the basics of planting these tough little plants.

  1. Choose a container: Cast Iron Plants prefer to be slightly root-bound, so choose a container that is only slightly larger than the plant’s root ball.
  2. Add soil: Use a well-draining potting mix that is rich in organic matter.
  3. Plant the Cast Iron Plant: Place the plant in the center of the container and backfill with soil until it’s level with the top of the root ball.
  4. Water thoroughly: Water the plant until water begins to drain out of the bottom of the container.

How Much Space Should You Leave Between Each Cast Iron Plant?

When it comes to spacing Cast Iron Plants, there are a few factors to consider:

  • Size of the container: If you’re planting multiple Cast Iron Plants in one container, you’ll need to leave enough space for each plant to grow. A good rule of thumb is to leave at least 2-3 inches between each plant.
  • Size of the mature plant: Cast Iron Plants can grow up to 2-3 feet tall and 2-3 feet wide. If you’re planting them in the ground, you’ll want to space them at least 2-3 feet apart.

It’s also worth noting that Cast Iron Plants have a slow growth rate, so you won’t need to worry about them overcrowding their container or growing too quickly.

Caring for Cast Iron Plants

Cast Iron Plants are known for their ability to thrive in low-light conditions and tolerate neglect. However, they still require some basic care to stay healthy and happy.

  • Light: Cast Iron Plants prefer low to medium light conditions. Avoid placing them in direct sunlight as this can scorch their leaves.
  • Water: Water the plant when the top inch of soil feels dry. Cast Iron Plants can tolerate periods of drought, so don’t worry if you forget to water them for a week or two.
  • Fertilizer: Cast Iron Plants don’t require much fertilizer, but you can give them a boost with a balanced, water-soluble fertilizer once a month during the growing season (spring and summer).
  • Pruning: Remove any yellow or brown leaves as they appear. You can also prune back any leggy stems to encourage bushier growth.
