Learning How to Grow a Big Venus Fly Trap Plant is an art – from selecting the right soil mix to understanding its unique feeding requirements, we’ll tell you everything to make this carnivorous plant a living giant!

Here’s what you need to feed to your Venus Fly Traps

Venus Fly Trap Plant – Their Size and Spread in General

Venus flytraps (Dionaea muscipula) are native to a limited region in the United States. They are indigenous to subtropical wetlands in parts of North and South Carolina. They are small, distinctive plants that can reach a height of about 4 to 6 inches when fully mature when grown as houseplants. 

Leaf and Trap Size Details

  • Each leaf, including the trap, measures approximately 3 to 7 inches long.
  • The actual trap portion is usually around 1-2 inches long.
  • The size of the traps can vary, influenced by factors such as the plant’s age and environmental conditions.

Spread and Height in Detail

  • The spread of a Venus flytrap, which refers to the diameter of the plant, including its leaves (Along with its stem), typically ranges from 5 to 7 inches.
  • In terms of height, Venus flytraps maintain a relatively low profile, growing vertically to about 4 to 6 inches. It can extend to 8-12 inches if it grows flowers.
  • During their dormant period in winter, the plants may appear smaller as some leaves die back or shrivel.

Fun Fact: Venus fly traps may appear quite large in pictures, but they are quite tiny in person!

Giant Venus Fly Trap Plant Varieties

These plants are measured according to their trap size. These giant varieties have 1.5-2 inches trap size, unlike their counterparts, which have 0.5-1 inches. 

1. Dionaea Muscipula ‘B52’

Size: Up to 2 inches in trap size.

True to its name, ‘Ginormous’ develops large traps through a combination of high light exposure and consistent feeding.

How to Grow a Big Venus Fly Trap Plant?

1. Maximize Sunlight Exposure

Maximize Sunlight Exposure

Venus Fly Traps crave sunlight. Position them where they can bask in direct sunlight for at least 4-5 hours a day. This will help them to develop their trap sizes to the max.

2. Use the Right Type of Water for Consistent Moisture

Use distilled, RO, or rainwater and keep the soil moist but not waterlogged. Moisten the growing medium only when it feels slightly dry to the touch.

Note: Do not let the growing medium dry out completely.

3. Feeding for Size

Though you don’t have to additionally feed these plants as they get all the nutrients they need from their diet of insects, here’s what you can try to grow their size.

Get an orchid liquid fertilizer (Or a balanced liquid fertilizer) and dilute 10ml of it with 100ml of water. Now, use this solution to spray the leaves once in 10 days. This may be a trial and error thing, but it can increase the size of the plant and its traps.

Note: This should be done sparingly to avoid foliage and root burn.

4. Temperature and Humidity Control

Temperature and Humidity Control

Maintain a humid environment, especially in drier climates. A range of 70-95°F is ideal if you want to see your Venus fly traps achieve their biggest size!

5. Re-potting for Growth

A plant trapped in a small pot for years may not achieve its full potential. Re-pot every 2-3 years to provide fresh soil and room for root expansion, contributing to the overall size.

Do not use an overly large pot – a new container, just one size bigger than the old one, will be perfect.

6. Selective Pruning

How to Grow a Big Venus Fly Trap Plant Selective Pruning

When dead traps are pruned, the plant conserves energy that would otherwise be spent on these non-functional parts. This allows the plant to redirect its energy towards producing new, healthier traps and leaves.

The conserved energy can result in the growth of larger traps, which are more efficient in capturing prey. With more significant and healthier leaves, the plant can perform photosynthesis more effectively, further boosting its overall health.

Important: Before you embark on the journey of growing the biggest or giant Venus fly trap plant, remember that these plants can’t grow bigger than you expect them to. The biggest varieties have a trap size of a maximum of 2 inches – so you can imagine! 

You can surely use some of the tips mentioned above to help them thrive better and enhance their growth but do not expect dramatic results.

Maximizing Dormancy for Growth in Venus Fly Traps

Maximizing Dormancy for Growth in Venus Fly Traps
The dormancy period is often overlooked aspect while growing Venus Fly Traps, yet it plays a crucial role in their health and size. 
  • Dormancy in Venus Fly Traps is akin to hibernation in animals. As the days shorten and temperatures drop, these plants enter a resting phase. This period typically spans from late fall to early spring.
  • During dormancy, the plant conserves energy, focusing on root development and internal strengthening. This phase is essential for their long-term vitality and subsequent growth.
  • A typical dormancy period lasts for about 3 to 4 months. It’s important not to interrupt this cycle prematurely.

1. Providing the Right Conditions

Venus Fly Traps require cooler temperatures between 35°F to 50°F (1.6°C to 10°C) during dormancy. While the plant needs less light during this phase, some exposure to natural light is still beneficial.

  • Indoors: If you’re in a region with harsh winters, move the plant indoors to an unheated room or a cool garage.
  • Outdoors: In milder climates, the plant can stay outdoors, possibly with some protection against extreme cold.

Also, reduce watering – keep the soil slightly moist but not wet. Overwatering can lead to root rot.

2. Post Dormancy – Spring Time

As spring arrives, gradually reintroduce the plant to its regular growing conditions. Increase watering and expose it to more sunlight. This transition from dormancy to active growth is when you notice a significant surge in size and health.

The energy conserved and redirected towards root development during dormancy results in more robust growth in the following season. You’ll often see larger traps and more vigorous plant activity.

Common Mistakes to Avoid

  • Avoid the temptation to stimulate growth during dormancy with artificial light or heat. This can stress the plant and reduce its lifespan.
  • Overwatering during dormancy is a common mistake. It can lead to fungal infections and root decay.
