It is very important to use nutrient-poor soil to grow Venus Flytraps. Regular potting soil or enriched soil will burn the roots and kill your Venus flytrap very quickly. We do not recommend fertilizing Venus flytraps. The fertilizer can burn the roots and likely kill the plant.
Some expert growers use extremely diluted fertilizer. In most cases, fertilizer is applied only to the leaves of the plant. This is risky and not recommended for a novice grower. It is best to simply allow your Venus flytrap to catch food on its own. It can also be fed mealworms or other insects.
Venus flytraps prefer growing in a sphagnum-based soil mix. Perhaps the easiest medium to use is simply pure, unenriched (NO Miracle-Gro!) peat moss or long-fiber sphagnum moss. Most retailers that carry potting soil sell large bales of peat moss.
It is generally agreed that a 1:1 mix of peat and perlite is the best medium for potting Venus flytraps. When choosing a brand of peat moss, any type will do as long as it isn’t enriched.
Venus flytraps are carnivorous plants that thrive in nutrient-poor, acidic soils. Their native habitat consists of peat bogs and wetlands in North and South Carolina. This raises an important question for flytrap growers – can you use regular succulent soil for Venus flytraps instead of the recommended peat/perlite mix? Let’s take an in-depth look at whether succulent soils are suitable for these fascinating carnivores.
An Overview of Venus Flytrap Soil Requirements
Venus flytraps need a soil that mimics the conditions of their natural Carolina bogs. Specifically, their soil should have these characteristics:
- Acidic pH between 3.5 to 5
- Low in nutrients and minerals
- Able to hold moisture but still drain well
- High in organic material like sphagnum peat moss
A typical flytrap soil recipe is a mix of 60-70% sphagnum peat moss and 30-40% perlite or sand. This gives them the acidity moisture retention and aeration they require. Some growers also add a small amount of horticultural charcoal to absorb toxins.
Comparing Succulent Soil Ingredients
Succulent soil mixes are designed for drought-tolerant plants that prefer dry, mineral-rich conditions – essentially the opposite of Venus flytraps! Here are some common components of bagged succulent soils:
- Coconut coir – retains moisture but neutral pH
- Compost – too high in nutrients
- Bark/wood chips – risks mold and fungi
- Sand or gravel – too free-draining, not acidic
- Perlite or vermiculite – useful addition but not acidic
- Fertilizer – much too high in nutrients
As you can see, most of these ingredients will not provide the right conditions for flytraps. The biggest issues are incorrect pH, excessive minerals, and ingredients that retain too much or too little moisture
Problems Using Succulent Soil for Flytraps
Here are some of the main problems that can arise from using regular succulent soil for Venus flytraps:
-
Incorrect Acidity – Flytraps need very acidic conditions below pH 5. Most succulent soils tend to be neutral or just slightly acidic. This can hinder nutrient absorption for the flytraps.
-
Excessive Nutrients – Succulent soils are designed to be nutrient-rich to support desert plants. The high mineral content can literally burn the roots of flytraps adapted to nutrient-poor bogs.
-
Poor Drainage – Some succulent soil components like coconut coir hold onto moisture too tightly. Flytraps need a more open, free-draining mix to prevent root rot.
-
Lack of Organic Matter – Peat provides flytraps the organics and antimicrobial benefits they’ve adapted to. Succulent soils may lack enough organic material for flytraps.
-
Compaction – Ingredients like fine sand can compress over time, reducing drainage and aeration. Flytraps thrive in loose, fluffy soil.
-
Mold Risk – Wood chips and bark carry mold spores that can spread in the perpetually moist flytrap soil. This can lead to root disease or crown rot.
Are There Any Exceptions?
The main takeaway is that regular, bagged succulent and cactus soil mixes are poor choices for Venus flytraps. However, some specialty succulent soils may work if blended properly:
-
Some acidic succulent mixes designed for plants like gardenias could have potential if amended with peat moss.
-
High-quality bonsai soils often have an acidic pH and lower fertility, making them more suitable.
-
Mixing a small amount of succulent soil may help increase drainage and aeration in very dense peat.
-
Homemade succulent soils are easier to tailor to flytraps by adjusting components like pH adjusters.
Even with these exceptions, peat and perlite remain far superior choices compared to commercial succulent soils. Flytrap growers are best sticking with traditional bog-simulating soil recipes.
Creating Your Own Venus Flytrap Soil
If you want to create a tailored soil mix, here are some suitable components to use:
-
Sphagnum peat moss – Forms the bulk of the mix. Look for premium grade for fewer contaminants.
-
Horticultural perlite – Creates air pockets and drainage. Use coarse perlite.
-
Play sand – Can help increase drainage further. Pick an acidic, organic kind.
-
Horticultural charcoal – Helps absorb toxins and provide trace minerals
-
Ground pine bark – Boosts acidity and mimics native soils. Use in moderation.
A basic homemade flytrap mix is 60% peat moss, 25% perlite, 10% sand, and 5% charcoal or pine bark. Mix the ingredients together thoroughly and re-pot established flytraps in this soil.
Additional Tips for Flytrap Soil
Here are some other quick tips for providing Venus flytraps the best growing medium:
-
Re-pot plants every 2-3 years as the peat moss decomposes over time.
-
Top dress pots annually with new peat moss to restore acidity and organics.
-
Use distilled, reverse osmosis, or rain water to maintain an acidic pH.
-
Test soil pH every few months using an inexpensive soil test kit.
-
Rinse peat thoroughly before use to remove excess salt and dirt.
-
Don’t add fertilizer – flytraps get nutrients from insects they eat.
-
Monitor soil moisture closely and don’t over-water, especially in winter dormancy.
With the right soil recipe and care, you can keep your flytrap’s roots and rhizome healthy for years of vigorous growth and insect-catching!
Final Thoughts
Commonly used Venus flytrap pots
Plastic pots are easy to find, cheap and will work well for Venus flytraps. However, most plastic pots are dark in color and therefore absorb heat. Given the fact that they aren’t insulated, the soil temperature can rise and fall quickly in the pot. Having said that, I’ve used these pots successfully and my plants did well. But when I made the switch to insulated pots, the difference in their health was noticeable.
Insulated foam beverage cups or styrofoam cups work well and are in inexpensive choice for a pot. They’re white, so they don’t heat up much in direct sunlight. Choose cups that are 16 ounces or more. They provide excellent insulation for the roots of the Venus flytrap. At over 4. 5″ tall, they provide good vertical space for your Venus flytrap to develop a healthy root system. To top it off, you can purchase twenty of them for one dollar, so the price is right!.
Avoid soil with fertilizers
Be sure to avoid peat moss brands like Miracle-Gro and Scott’s. They contain fertilizer that will kill your flytrap. Peat Moss and Perlite.
Perlite is also relatively easily found at large department and hardware stores, or at your local nursery. Perlite provides aeration and optimum moisture retention. Many people substitute silica or horticultural sand for perlite.
There is a “standard” CP mix that is made up of equal parts peat and perlite. This is because most carnivorous plants do well in this medium. Many growers like to use the standard CP mix and then top it off of long-fibered sphagnum moss. This prevents the perlite from floating to the top. When exposed to heavy rains, perlite has a strong tendency to float to the top of the soil.
Five parts peat moss, three parts silica sand, and two parts perlite by volume is the best soil mix for Venus flytraps. The silica sand really helps with aeration and the formation of a very healthy root system. Silica is a very hard mineral that is not soluble and is completely neutral and inert. This makes it perfect for carnivorous plants because it will not release any minerals into the soil. Silica Sand.
Choose an adequately large container that will allow you to mix the peat and perlite without spilling it. A five-gallon bucket works well.
Add peat moss to the mixing container. First: Add Peat Moss
Then add the perlite. Second: Add Perlite
Lastly, add some distilled water and mix. Add Distilled Water
Add a lot of water to the mix because the peat moss can hold much water. Keep adding water and stirring the mixture until the peat moss is completely wet and the perlite is well blended in. Peat moss has a tendency to repel water initially, especially if it is cold. However, it will eventually start soaking up the water. Ultimately, you should end up with something that looks like this: Standard Carnivorous Plant Soil Mix.
Venus Flytrap – 5 Common Mistakes to Avoid for a Vibrant Plant
Can Venus flytraps grow in succulent soil?
Some are curious if succulent soil is appropriate for Venus flytraps. Venus flytraps can not be potted in succulent soil. The common ingredients for succulent soil are sand, perlite, and potting mix. The sand and perlite are common ingredients for carnivorous plant soil, but the standard potting mix is unsuitable.
