If you’re looking for a crazy cool plant with stunning fenestrations, look no further. Rhaphidophora Tetrasperma is an affordable plant that looks like it costs more than it is. This plant gets huge (even in your home!) and I’ve seen one easily over 15 feet long.

Rhaphidophora Tetrasperma is a fairly easygoing plant that doesn’t even need high humidity. If you’re looking for a plant to buy, this one is it.

Rhaphidophora Tetrasperma main care directions.

  1. Light. Place this plant in bright indirect sunlight, near a south, east, or west facing window. This plant works under plant grow lights like T5 Barrina grow lights (what I use).
  2. Water. Stick your finger in two inches deep into the soil – if it’s dry, it’s time to water your plant.
  3. Soil. Well-draining potting mix is a must. Use a homemade recipe or a high quality potting mix like Fox Farm Ocean Forest.
  4. Humidity. No special humidity requirements. I keep my R. Tetrasperma in regular household humidity (20%).

Rhaphidophora Tetrasperma thrive in the home with these care tips.


Just like most plants, Rhaphidophora Tetrasperma thrive in bright, indirect sunlight. Think of an area in your home that is getting a good amount of sunlight coming in. Typically, this is near a south, east, or west facing window.

If you don’t know which direction your windows are facing, use a free Compass app on your phone. This is the easiest way to check and it’s worth it to know what kind of sunlight you’re getting into the home.

South facing windows gives you the best amount of sunlight all day long. It’s also some of the most intense, which is why it’s important to place a sheer curtain on the window to break up some of that strong sunlight.

I have my Rhaphidophora Tetrasperma in a south facing window hanging from the ceiling. This plant is growing much quicker here than it was when I had it in an east facing bedroom (morning sunlight, and not a lot of it).

Don’t have a lot of sunlight coming into the home? No worries, use plant grow lights like I do. I have two greenhouses and one shelf that store about 100 plants. They’re all growing under T5 Barrina plant grow lights. T5 Barrina plant grow lights is a full spectrum sunlight replacement. They are incredibly easy to install and haven’t raised my electricity bill a noticeable amount. You can even use these lights for plants in a seedling, vegetative, or flowering cycle. These lights include double-sided tape, clips, and cable ties. I use the double-sided tape to stick the lights on.


This plant is simple and has basic watering needs. Stick your finger in the potting soil about two inches deep. If the soil feels dry, it’s time to water your plant. If the soil is wet, it’s not time to water your plant. Easy, right?

If you have trouble knowing when to water your plant, I find a moisture meter really helps. I use this moisture meter and it’s easy and convenient to use. This handy tool doesn’t require batteries and helps me check plants in hard to reach places. Insert the moisture meter probe about 2-5 inches into the soil. If the meter reads on the dryer side, it’s time to water the plant.


Rhaphidophora Tetrasperma thrive in well-draining soil. This kind of soil is important because compact, dense soil often leads to root rot and once your plant gets root rot, it’s not looking so good for the plant.

What does well-draining soil look like? Something like Fox Farm Ocean Forest potting mix is a great option for those of us that don’t want to make our own potting mix. This potting mix has a blend of earthworm castings, bat guano, sea-going fish and crab meal, forest humus, moss, and other key ingredients.

If you do want to make your own potting mix, an easy recipe calls for 40% coco coir, 25% perlite, 25% orchid bark, and 10% vermiculite.

If you have a ton of houseplants you need to repot in new potting mix, your money goes further if you make your own potting mix instead of buying a pre-made bag.


Rhaphidophora Tetrasperma thrive in temperatures between 60°F and 85°F (15°C and 29°C). If you place this plant outside, make sure it’s not in a spot getting direct sunlight.


Fertilizing your houseplants is one of the best things you can do to encourage growth.

There are many fertilizers on the market to choose from and it can get a little confusing, so I’m going to keep things as simple as possible. You can choose from a granule-based fertilizer, liquid fertilizer, or natural fertilizer like worm castings.

It doesn’t really matter which fertilizer you use, but there are key things to know. If using a synthetic fertilizer (you’ll know if it’s synthetic if the NPK ratio is something like 20-20-20) you need to dilute the recipe in half. This is because synthetic fertilizers are really strong and can damage your plant.

It’s also important that you only fertilize during the active growing season. This is typically March through October for many of us.

How often you fertilize is up to you. I fertilize every watering because this keeps things simple for me, but you can choose to fertilize every other watering, bi-weekly, once a month, etc.

You’ll notice some plants need fertilizer more than others. For example, Monstera Deliciosa is one of those plants that are heavy feeders.

I use both Liqui-Dirt (plant food, not technically a fertilizer but it has everything your plants need to grow healthy) and Dyna-Gro fertilizer. With Dyna-Gro, I get a spoonful and mix it into a gallon of water. I use this gallon to water my houseplants.


One of the best things about this plant is that it doesn’t require any special humidity. I have my plant in a room getting about 20% humidity and it’s growing with no problem.

If you decide to give your plant extra humidity, that’s not going to hurt. You’ll probably even see some faster growth because you’re doing this.

Here are my best tips for increasing humidity around your plants.

  • Place a humidifier near your plants and run it daily
  • Group plants together – this creates a microclimate of higher humidity
  • Place a tray under the plant and fill with rocks and water – the water evaporates around the plant
  • Put your plants in a greenhouse (I made a greenhouse with an IKEA cabinet and it stays around 50% humidity with plants, no humidifier necessary)


Propagating a Rhaphidophora Tetrasperma is easy peasy. This plant has nodes making it one of the easiest plants to propagate.

With clean cutting sheers, cut below a node on the stem of the plant. Nodes look like little hard pimples on the stem. Submerge the node underwater and in a few weeks, the node will have roots growing out of it. Once the roots are a few inches long, move the cutting to your preferred substrate. This plant loves well-draining soil, so something like Fox Farm Ocean Forest potting mix will work great.

This is a photo of a Rhaphidophora Tetrasperma node. I’d cut right below this node if I wanted to propagate this plant.
