Searching for an Anthurium Crystallinum care guide? Look no further and let Sumo Gardener help you learn everything you need to know about this beautiful plant. 

The Anthurium Crystallinum or commonly known as Crystal Anthurium is a large houseplant that’s become popular because of its large leaves which can grow up to 3ft (90cm).

It’s indigenous to parts of Central and South America (Panama, Peru, etc.) but even though it’s a tropical plant, it can still be grown indoors.

So let’s see how to grow this fascinating plant right there in your own home.

Anthurium Crystallinum Care Guide

Watering Your Anthurium Crystallinum

Watering your anthurium might be the easiest part of care.

You need to assure that you give your plant a constant watering cycle and especially take great care during the season.

Because this plant is used to wet conditions, you should water it once every 3-4 days and always let the top part of the soil dry before watering it again. 

Make sure to use the right watering can for the job to avoid overwatering your gorgeous plant. 

During the colder months, however, you should water it once every week or two depending on how much water your anthurium soaks up.

The type of water you use is also important and you want to use either rainwater or distilled water because these types of water are close to being pH neutral.

Tap water contains alkalines making the pH levels higher than the plant has been used to in its natural habitat and you do want to reconstruct that as much as possible.

Using the Right Light and Temperature

As far as light is concerned your anthurium crystallinum will mostly enjoy partial shade accompanied by natural sunlight.

Be careful not to expose your anthurium to direct sunlight as the leaves can get yellowish and start to wilt.

Of course, the lighting requirements will change depending on the season so, in warmer months, your plant will need about 6-8 hours of partial shade while in the colder months it’s perfectly fine to use artificial lighting.

The temperature on the other hand is the hardest condition to control.

If you live in a hotter climate (tropical or subtropical), you’ll have no problem growing your anthurium as this plant thrives in temperatures around 60-70°F (15.5-21°C).

Colder climates, however, are a bit too harsh for anthurium crystallinum, and temperatures below 55°F (13°C) can seriously damage your plant.

That’s why keeping it indoors in a spot where it’s warm but also sunny is your best option.

Things such as artificial lighting, heat mats and even growing tents can also be useful.

Best Soil for Anthurium Crystallinum

Anthurium crystallinum care

Anthurium crystallinum typically grows in loamy perlite-type soil and that’s exactly what you’ll need if you want to grow it indoors.

There are already pre-mixed soil mixtures on the market made specifically for anthuriums but if you want you can make your soil mixture yourself.

And it’s maybe best to use a DIY mixture as it is not only cheaper but also a lot better for your anthurium.

First, you’ll need some loamy soil that has good drainage so water can escape through and not accumulate near the roots so that they don’t rot away.

Second, you’ll need some peat moss or coconut coir to hold the soil together as well as some perlite to make the soil more acidic (around 5.5 pH) which anthuriums love.

Finally, you need the right plant pot for your anthurium, and terracotta pots are the best but you can also use plastic pots as they don’t retain as much water.

Fertilizering Anthurium Crystallinum

Fertilization is always optional but it’s a good way to get nice foliage on your anthurium.

If you’re planning to grow your anthurium indoors, then fertilizers are definitely going to help you provide the nutrients that your plant would get if it was grown outdoors.

Now, there are a lot of fertilizers on the market for anthuriums but you should always stick with the organic fertilizers and use as fewer chemicals as possible when taking care of any plant.

Your best 2 options are either mild liquid fertilizers which you’ll need to use once every 2 weeks or one month or using a slow-release fertilizer which should be used just a couple of times during the season.

Also, make sure to use fertilizers that are rich with phosphorus as it will help the roots and leaves be healthy and.

Always the first test out a fertilizer before pouring it all on your plant and never use fertilizers when the growing season is over as your plant won’t need all the nutrients and it can get damaged.

How to Propagate Anthurium Crystallinum

Using the parts of your anthurium to grow new plants is definitely better than to grow them from seeds.

You can propagate either by division or by cuttings.

When propagating by division, you need to get the root-ball out and see if there are any loose stems you can then re-pot in a separate pot.

This is the easiest way to grow another anthurium.

However, you can also cut off the stem that has a few roots and re-plant it as well but just make sure that your anthurium is mature (3-4 years old at least) otherwise you can damage it.

When you’re done propagating, be sure to give your newly planted anthurium lots of water and a shady place so it can rest at least for a couple of weeks.

Pruning Anthurium Crystallinum

Pruning is an essential part of anthurium crystallinum care.

You might notice that some of the leaves are turning yellow or brown and that some stems might bend to the side.

If there is discoloration on the leaves, it means that your plant isn’t getting enough water and you’ll need to cut off the yellow parts of the leaves so they can regenerate.

On the other hand, if you see that some stems are starting to bend it means that they’re wilting and you should cut them off so they don’t take up nutrients from the rest of the plant.

Pruning should be done during the season because the plant is too weak during the colder months.
