From Our Nursery to Your Collection: How We Grow Your Plants




Hello, I’m Joel Garner, the owner of this American family-owned business you’re visiting and supporting — Joel’s Carnivorous Plants.

I’m the world’s largest seller of carnivorous plants by volume. Read more about me here! This is part 1 of a 2-part series that explains how we grow and ship your plants. Be sure to also read part 2, which explains how we ship your plants.

Here at my family’s nursery in Wilmington, North Carolina — the native range of the Venus flytrap, I stock anywhere between 100-200k Venus flytraps, pitcher plants, sundews, and other carnivorous plants at any given point in time. If you’re considering purchasing a Venus flytrap or other type of carnivorous plant, you’re in for a real treat. Let me bring you behind the scenes so I can show you how we grow our plants and ship them to you — our wonderful customers!


Indoor Hardening For Plantlets: 1-5 Months

Preparing the Substrate and Growing Medium

A solid growing setup always begins with choice of substrate. We use dried sphagnum moss as the primary substrate for all of our Venus flytraps and carnivorous plants. Sphagnum is an ideal substrate for a few reasons: it is low in minerals, maintains constant water absorption, and is porous, which enables air to circulate around roots. At carnivorousplants.com, we primarily use long-fibered New Zealand sphagnum moss, but also use Chilean and Peruvian sphagnum when the New Zealand variety is in short supply.

We grow our plantlets in 5″ and 6″ mesh pots in trays of pure RO water. All carnivorous plants, and particularly Venus flytraps require abundant pure water in order to thrive. Before we can use it for planting, each piece of fresh sphagnum moss is presoaked and fully saturated in pure RO water–from the same source we use to fill our water trays the pots stand in during the grow out phase.

Staging the Plantlets in their Controlled Indoor Growing Environment

Each of our 5″ and 6″ mesh grow out pots have webbing structurally built into them that allows for ample air and water flow into our plants’ root systems. Each pot contains 5-6 juvenile plantlets and stands in water trays constantly filled to a 1″ water depth. A quick note about water: it is absolutely critical to use pure or RO water when working with carnivorous plants. Depending on one’s circumstances, rainwater may NOT be sufficient, since chemicals and minerals may have had an opportunity to seep into the water prior to collection. For example, water runoff from a roof will likely contain asbestos and other chemicals that can kill your plants.

Our young plants — all from tissue culture, are grown in a large indoor grow tent. They reside here for several weeks up to many months. We use red and blue 28W LED grow lights. Our timer is set to 16 hrs of light per day, and as little as 11 depending on weather. For example, during winter, the lights are left on for a long time: 2-3 days straight, and only 11 hours on summer days. All of our plantlets are grown in trays of constantly filled RO water. We believe this setup instills plants to achieve peak growth–that is, it is not actually biologically possible for them to grow faster in any other set of conditions. Strong lightning is the most important aspect of growth. Temperatures range from 70-93F. Our lights are turned on during night and off during the day. We do not overheat our plants, and no temperature drop is necessary.

A tremendous advantage our Venus flytrap stock has is that our younger plants do not yet have awareness of the time of the year. Since they have recently emerged from tissue culture, they are NOT dormant during winter time, which allows us to ship live impressive plants during winter months. We use a CO2 canister for faster and sturdier growth– allowing our plants to be more hardened off than plants grown in traditional greenhouses. High humidity is not a hard requirement, but it does allow plants to grow faster. Our combination of temperature, humidity, CO2, and pure RO water is a magic formula that allows our plants to harden and thrive.


Outdoor Grow-Out, Additional Hardening: 2-12 Months

Our outdoor growing frames are built with sturdy PVC piping. At any given point in time, we have 100-200k carnivorous plants growing in our outdoor facilities. Each year, we hold back stock plants in order to prepare for future inventory or for propagation purposes for the next year.

When our plants graduate from our intense indoor regimen, they are ready for the next phase of their lives: outdoor growing. During spring, summer, and autumn months, young plantlets are exposed to full sun with 30% reflective shade cloth from anywhere between 2-12 months depending on the season. 30% reflective shade cloth. Light goes through it and it diffuses, which allows for an even distribution of light. On overcast days, we remove the cloth in order to allow the plants to photosynthesize more — resulting in more colorful and sturdier plants. It’s important to note that our results are not achievable with a traditional greenhouse setup. Due to the opaque nature of white-painted greenhouse glass, plants are not able to photosynthesize as effectively as they are outdoors. Our shade cloth setup is more maintenance intensive and expensive, but the results are worth it.

During this phase, young plants are exposed to actual natural growing conditions while being protected from birds and small mammals that would otherwise disturb the plants. This final phase is called the outdoor hardening phase, and young plants that have no seasonal awareness have the opportunity to develop to maturity. This process can take anywhere between 2 to 12 months. Mature plants have the opportunity to be subdivided into smaller plants for additional propagation. If the plantlets are small enough, they are moved back into our indoor setup to repeat our indoor growing process over the next few months.

Winter Season Transition: 1 Month

We allow all our mature plants that must be acclimated to winter conditions to do so. During the fall, we allow our Venus flytraps, sundews, and sarracenia to cool down and slowly adapt to the coming winter. This means that the root systems will gradually cease a rapid pace of growth. New leaves and pitchers will stop forming during this stage. We cover all our plants with protective coverings and prepare their enclosures in order to ensure their survival and prepare them for a smooth winter.

It’s important to note that during the winter months, we never ship outdoor plants that are undergoing their cooling period. During these months, we only ship ready specimens from our indoor facility that have been hardened off without seasonal awareness. This means that when customers receive the plants, they will have traps, leaves, and be ready to enjoy from day 1. Special care will need to be provided to plants shipped during winter. We have detailed instructions specifically for winter growing that accompany each plant we sell. At our nursery, we ship plants all 12 months of the year regardless of the weather. In order to ensure our plants’ smooth journey to your home, our shipping containers always include ice packs when necessary during summer months, and heat packs during winter months.

Ready to Ship to Your Home or Business!

Finally, after all of our hard work, our plants are ready to be shipped to your home and become exciting new members of your carnivorous plant collections. We use an advanced ticketing system to track orders. Although rare, we always rectify shipping mistakes that arise. For example, if a customer is owed a plant that was accidentally omitted or USPS and/or FedEx kill a plant, we will send a replacement shipment free of charge.

During our spring and summer months, mature plants are taken from our outdoor growing space and prepared for shipping.  The mature plant pots you see in the photo contain anywhere between 6-15 adult plants. We use this inventory to fulfill our Mature and Adult Specimen orders. Each plant we sell includes its own plant kit that ships with a generously-portioned moss plug to retain moisture during transit. Additionally included in this kit is our 3″ professional grower’s-grade porous plastic pot and enough top-quality long-fiber moss to completely fill it– the exact same kind we use at our nursery for a seamless transition to your collection. Planting and detailed care instructions will also be included for a complete growing experience.
