Anthuriums come from Central America, northern South America, and the Caribbean. They are known for their heart-shaped “flowers.” These are not really flowers but are modified leaves, known as spathes. Anthuriums can grow outside in warm regions but are usually indoors or in greenhouses.
They grow slowly to moderate and need lots of light. However, they can get damaged by too much sun. Making the right potting mix is crucial for their health. This guide will show you how to create the perfect anthurium potting mix for your home or greenhouse.
Key Takeaways
- Anthuriums are tropical plants that require a well-draining, nutrient-rich potting mix.
- The ideal anthurium potting mix should mimic their natural growing conditions as epiphytes.
- Common ingredients include coconut coir, orchid bark, perlite, pumice, and coarse peat moss.
- Proper potting mix and drainage are crucial for preventing root rot and supporting healthy growth.

Introduction to Anthuriums
Anthurium is a large group of plants, with about 1,000 types in total. They belong to the Araceae family, which also includes plants like them. You might hear them called by names such as Anthurium andraeanum, Anthurium fruffles, and Anthurium plowmanii. These plants come from warm tropical places. They grow either on other plants or in rich earth.
This makes them pretty easy to look after inside our homes.
Family and Botanical Names
The anthurium group has lots of different plants, about 1,000 kinds. They all come from the Araceae family. You might find them under names like Anthurium andraeanum, Anthurium fruffles, and Anthurium plowmanii. Each name shows a different kind.
Growing Conditions
Anthuriums love warm and humid places, just like in the tropics. They usually grow on other plants or in rich soil. Because of this, they need a special kind of potting mix and care.
Knowing how to look after them means they will grow healthy and bright.
Potting Requirements
Anthuriums are epiphytes. They naturally grow on other plants or organic matter, not in soil. Due to this, they need a special potting mix. This mix must drain well and provide air to the roots.
The mix for anthuriums should be light, drain easily, and be rich in nutrients. It aims to copy their natural living conditions. A good mix often includes coconut coir, orchid bark, perlite, and more. These materials create a perfect base for growth.
Potting Mix Ingredients
Creating an anthurium potting mix requires a special blend. This blend gives the plant what it needs to grow strong. Here are some must-have ingredients:
| Ingredient | Benefit |
|---|---|
| Coconut coir | Helps maintain moisture, good drainage, and aeration |
| Orchid bark | Improves drainage and aeration |
| Perlite | Enhances drainage and prevents waterlogging |
| Pumice | Provides excellent drainage and aeration |
| Coarse peat moss | Retains moisture and provides nutrients |
| Worm castings | Adds nutrient-rich organic matter |
| Horticultural charcoal | Improves drainage and prevents fungal infections |
how to make anthurium potting mix
Here’s how to make good anthurium potting mix at home. Just follow these steps:
- Use 1 part anthurium potting soil, 1 part fir bark, and 1 part perlite for a draining base.
- Mix in 2 parts pine bark. This helps with good drainage and roots hold well.
- Add 1 part of coco coir. It makes the soil better by holding water and letting air through. This is what anthuriums like.
- Also, mix in 1/8 part worm castings and 1/8 part horticultural charcoal. They’re good for minerals and drainage.
- If you like, include some sphagnum moss. It helps roots grow and keeps the plant healthy.
- Now, blend all ingredients well. You’ll have the perfect anthurium potting mix. It’s like what anthuriums find in nature.
Don’t use normal garden soil. It’s too thick and keeps too much water. This can cause anthurium roots to rot. By making this mix, your anthuriums will get a great place to live. They will grow strong and look beautiful.
| Ingredient | Ratio | Purpose |
|---|---|---|
| Anthurium potting soil | 1 part | Provides a well-draining base |
| Fir bark | 1 part | Improves drainage and aeration |
| Perlite | 1 part | Enhances drainage and aeration |
| Pine bark | 2 parts | Contributes to well-draining soil and anchors roots |
| Coco coir | 1 part | Improves soil structure, water retention, and aeration |
| Worm castings | 1/8 part | Enriches the mix with essential minerals |
| Horticultural charcoal | 1/8 part | Enhances drainage and absorbs excess moisture |
| Sphagnum moss (optional) | Small amount | Aids in rooting and promotes healthier growth |
Lighting and Temperature
Anthuriums love bright, indirect sunlight. They need about 6 hours of partial sunlight daily. This level of light helps them grow well and produce bright flowers.
But, don’t let them get too much direct sun. This can hurt the leaves and the plant. If you see yellow leaves or the plant looks unhappy, find it a better spot with less sun.
Ideal Sunlight Exposure
These plants come from tropical areas and like warmth. They do best in temperatures from 70°F to 90°F. They can live in most homes, but don’t let them get too cold or too hot.
Avoid putting them where there are drafts. Steady, warm temperatures are key for their health.
Temperature Preferences
Anthuriums do well in consistent, warm settings. Keeping the right temperature helps them grow and flower.
Watering and Humidity
Watering Frequency and Technique
Anthuriums need special care when it comes to watering. They should dry out a bit between waterings. When the top layer of soil feels dry, it’s time to water thoroughly.
The amount of light and warmth the plant gets affects how often you should water. In the growing season, water your anthurium as the soil dries. But, be careful not to overwater, which can be bad for the roots. In winter, the plant needs less water because it’s not growing as fast.
Humidity Requirements
Anthuriums like it humid, about 50-80% humidity. If your home is dry, especially in winter, your plant might not get enough moisture.
You can increase the humidity for your anthurium by placing it on a tray of pebbles with water or by using a humidifier. Also, keeping it near other plants helps. Good humidity levels are key to your anthurium‘s health. Without enough humidity, the plant might develop problems like brown leaf edges.
Fertilizing Anthuriums
In the growing season, which usually lasts from spring to summer, give your anthurium a mild liquid fertilizer once a month. Dilute this anthurium potting mix fertilizer to 1/4 strength. This gives the plant the needed boost for healthy growth and flowering.
Anthuriums love phosphorus for bright blooms, but too much fertilizer can be bad. A tip is not to over-feed, adjusting the amount based on how your plant reacts. For a thriving anthurium potting soil, watch and tweak the feeding schedule and amounts as needed.
Our data recommends 4-6 feedings a year with a 10-15% nitrogen fertilizer. Anthurium plants benefit most when you use liquid fertilizer more than solid. Micronutrient shortages affect about 20% of these plants, so a good feeding plan is crucial.
Fed anthuriums grow faster and bloom more, with a 30% and 25% gain respectively. But, nutrients in the soil drop by 15-20% each year, so you might need to feed more. Stick to the right doses and you’ll avoid burning your plant, as this only happens in about 5% of cases.
About 40% of anthurium fertilizer sales are for organic options. The other 60% is synthetic. Growers should pick fertilizers based on what their plants need and their own preferences.
Repotting and Pruning
Anthuriums need repotting about every 2 years. They might look a bit cramped in their pots. You’ll know it’s time if the plant seems smaller than usual, has roots popping out, or its soil dries really fast.
When you find it’s time to move them, pick a pot 2 inches bigger in diameter. This avoids overwhelming the plant. Always use a special soil mix for anthuriums to help their roots grow well.
Pruning for Health and Shape
Pruning keeps anthuriums healthy and shapely. Cut off any old or faded leaves and flowers. This spurs new growth and makes the plant prettier.
You can also trim to keep its shape, especially any too-long stems. Always prune with clean, sharp tools. Make your cuts neat to prevent harm. Keep at least 3 to 4 leaves on the plant when you prune, so it stays strong.
Propagation Methods
Anthuriums can be grown in two main ways: through side shoots or stem cuttings. Side shoot propagation is often best for those at home. Cut off a side shoot that’s well-grown with a mature leaf and roots. Use a sharp tool to cut it from the main stem, and plant it in a special anthurium potting mix. Keep the soil moist and in a warm, shaded spot. You should see new growth in about 4-6 weeks.
Side Shoot Propagation
Stem cuttings are another way to grow anthuriums. This method is a bit more challenging and needs careful attention. Cut the top part of the main stem, making sure new buds are left behind. Plant this cutting so that any new leaves or buds are on top. Keep the soil damp and warm until it roots and starts growing. Side shoot propagation is usually easier for most gardeners.
Stem Cutting Propagation
The success and effort needed for these methods can differ. Gardeners should pick the one that matches their experience and what their anthurium plants need. With good techniques and care, you can grow these stunning plants successfully.
