Can You Cut Caladium Bulbs in Half?

Like all flower bulbs, Caladium bulbs are delightful to have in your garden. Although these bulbs are reasonably durable, you do have to take measures to ensure that they grow in the best way possible. For example, can you cut caladium bulbs in half?

You can cut caladium bulbs in half. Cutting caladium bulbs in half will allow for more growth and is also a great way to propagate the plant. However, each half of the caladium bulb must have an eye or growth point. Otherwise, no plant will grow from the bulb.

The rest of this article will cover why you should cut caladium bulbs in half, the benefits of doing so, and how to cut them in half. I’ll also discuss the best time to cut caladium bulbs in half and some general caladium bulb care tips. Let’s get started!

Why Cut Caladium Bulbs in Half?

Cutting caladium bulbs in half can be beneficial depending on your goals for your plant. The main reason and benefit of cutting the bulbs in half are for propagation. 

However, the two halves must have an eye or growth point before you cut the bulb. If the halves don’t have these, you’ll be left with cut bulbs that are essentially useless — as opposed to two new sources of caladium growth.

Aside from propagation, there are other benefits of cutting caladium bulbs in half. I’ll go over these benefits in the following section.

Benefits of Cutting Caladium Bulbs

Although bigger bulbs, or “tubers,” usually result in more plant growth, dividing the bulbs up can also lead to more plants and fuller growth. 

Additionally, cutting the smaller buds from the original tuber has benefits including:

  • More (albeit smaller) caladium plants
  • More growth from the bulb
  • Bulbs sprouting quicker

Do I Have To Cut Caladium Bulbs?

Although there are many good reasons to cut caladium bulbs, it’s not really necessary.

As I’ve mentioned, the main reason to cut caladium bulbs is for propagation. So, if you don’t want to propagate your plant, there’s no need to cut it. However, cutting, or “scaring,” the buds on the bulb can encourage fuller plant growth, so it’s recommended before planting.

I’ll go more in-depth into scaring your caladium bulbs and the benefit of doing so below.

Scaring Your Caladium Bulbs

Scaring your caladium bulbs helps encourage more growth from your bulbs, leading to bushier (and, therefore, better-looking) plants. 

To successfully scar your caladium bulbs, follow these steps:

  1. Find the large, central bud on the bulb. This bud is typically near the middle of the bulb.
  2. Use a knife to cut the central bud out. Very carefully cut or “scar” the large bud without harming the smaller buds. Doing this forces the smaller buds to produce growth, which results in more leaves sprouting from the bulb.
  3. Watch the smaller buds as they begin to sprout leaves. If you leave the large central bud, the smaller buds won’t produce any growth. So, cutting out the central bud results in a bushier plant.

If you’re having problems with your caladium plant being leggy or not producing as many leaves as you want, the problem is likely in the bulb. Make sure you scar the bulb before planting it to achieve the best results.

How To Cut a Caladium Bulb in Half

While cutting (or scaring) your caladium bulbs has its benefits, it’s essential to know the steps to cutting a bulb in half as well — especially if you want to propagate the plant. Incorrectly cutting the bulbs can leave you with a dead plant.

Cutting caladium bulbs in half isn’t challenging, as long as you know what to look out for when handling the bulbs.

Before just cutting the bulb haphazardly, you need to familiarize yourself with the anatomy of the bulb itself. The bulbs (or tubers) can be in various sizes. The larger the tuber is, the more buds it likely has. 

That said, regardless of size, every tuber will have one large, central bud surrounded by many smaller buds (also known as eyes).

You must locate these buds before cutting them, as each side of the bulb must have at least one bud to sprout.

Now that you know a little more about the makeup of a caladium bulb, let’s get into the steps of cutting the bulb in half:

  1. Examine the bulb. If the bulb is too small, it might not have enough buds to produce a plant.
  2. Find the central bud on the bulb. Finding the larger, central bud will make it easier to locate where to cut the bulb in half.
  3. Find the smaller buds on the bulb. The smaller buds will surround the central bud. Ensure that the parts you cut have at least one smaller bud on each side.
  4. Cut the bulb accordingly. Use a clean knife to cut the bulb in half. Ensure your knife is completely sanitized before cutting. Otherwise, any harmful microorganisms on it may infect your growing plant and cause problems you’d rather not have to deal with.
  5. Let the bulb heal before planting. While this might not be absolutely necessary, it’s a good idea to give the bulb time to heal from the cut before putting it in the soil. That said, this likely won’t affect the bulb’s growth too much.

If you want to propagate a caladium plant that’s already sprouted and grown leaves, cutting the bulb in half will be much easier, as you can more easily see the buds where the stems are growing from.

When Should You Cut Caladium Bulbs?

When you should cut caladiums usually depends on where you live and your hardiness zone. In general, when propagating, it’s essential to cut the bulbs during the plant’s growing season.

The best time to cut caladium bulbs is in the spring, especially if you’re doing it for propagation. Therefore, you can plant the cut bulb together for more plants and fuller growth.

How Do You Make Caladiums Fuller? 

Like with most plants, one of the most reliable ways to make caladiums bigger is to cut parts of them. While this typically consists of cutting leaf stems or “leggy” stems to encourage more growth, with caladiums, it’s recommended that you cut the tubers.

You can make caladiums fuller by “scaring the eyes” of the bulb. Scaring the eyes consists of cutting the tip of each bud (including the large, central bud) to encourage more sprouting — leading to bigger, fuller growth in the plant.

As long as you don’t cut the bulb too deep, the bulb should be fine. Therefore, don’t stress if you think you cut too much out. The bulbs are durable and will still sprout leaves.

Caladium Bulb Care Tips

As I’ve repeatedly emphasized throughout this article, cutting caladium bulbs in half is an excellent way to propagate the plant. 

If you’re interested in caladium plants, here are some general care tips to keep in mind:

  • Ensure all your gardening tools are entirely sanitized. When cutting bulbs, it’s crucial that gardening tools, including shears or knives used, are sanitized. Using dirty gardening tools with the bulbs can introduce disease into the plants.
  • Shave off the smaller buds to encourage more growth. As mentioned, “scaring” the buds will allow the bulb to produce more leaves, making the plant much fuller.
  • Keep the caladium bulbs on the drier side. While the soil should be moist, overwatering the soil (and bulb) can easily lead to bulb rot, which can kill the bulb. It’s better to underwater than overwater caladiums, as it’s easier to pour in more water than remove excess moisture from the soil.
  • Know your hardiness level zone. Knowing the hardiness zone in your area is crucial for growing caladium bulbs properly, as it tells you when you should plant your bulbs, when to dig them up, and how to care for them in general.

Final Thoughts

You can cut caladium bulbs in half, and it’s a great way to propagate the plant to create more caladiums. However, you need to be careful when cutting the bulbs for propagation, as each side of the bulb needs to have at least one bud or growth point.

Additionally, when cutting the bulb in half, it’s crucial to use a gardening tool that’s completely sanitized, so you don’t introduce any diseases into the bulb. You should also only cut the bulb in the spring during the growing season.
