Can You Grow A Network Calathea Outdoors?

Have you ever found yourself mesmerized by the intricate patterns of a Network Calathea? You're not alone. This plant is a favorite among many for its stunning foliage, which can add a touch of elegance to any space. But what if you're tempted to take this beauty outside? Can you grow a Network Calathea outdoors?

In this article, we'll chat about the ins and outs of growing a Network Calathea outside. We'll cover everything from climate considerations to soil needs, and even touch on how to create a cozy outdoor spot for your plant. By the end, you'll have a good sense of whether your Calathea can thrive under the open sky.

Understanding the Network Calathea

Before we move forward, it’s essential to get to know the plant we're dealing with. The Network Calathea, known scientifically as Calathea musaica, is a tropical plant native to South America. Its leaves are adorned with a network-like pattern that resembles a mosaic, which is why it’s sometimes called the Mosaic Plant.

Calatheas belong to the Marantaceae family, often referred to as prayer plants. They have a fascinating habit of raising and lowering their leaves from day to night, almost as if they're "praying." This movement is a natural response to the light cycle, a behavior called nyctinasty.

These plants are well-loved for their striking appearance but are also notorious for being a bit finicky. They require specific conditions to thrive, making them a bit of a diva in the plant world. Understanding their native environment gives us clues on how to care for them, whether indoors or outdoors.

Climate Considerations

Now, if you're thinking about moving your Network Calathea outside, the climate is the first thing to consider. These plants hail from warm, humid environments, which means they prefer temperatures between 65°F to 85°F (18°C to 29°C). Anything below 60°F (15°C) can be quite stressful for them.

This temperature range makes them ideal candidates for outdoor living in USDA hardiness zones 10 to 12. If you're lucky enough to live in a region where the weather is consistently warm and humid, your Calathea might just thrive outdoors. However, if you experience cold winters, it might be best to keep the plant inside or bring it indoors during cooler months.

Humidity is another crucial factor. Calatheas love a humidity level of at least 50%, and in their native regions, it's often much higher. If you live in a dry climate, you might need to get creative with humidifying techniques to keep your Calathea happy. Think misting, pebble trays, or even a humidifier if you're really committed.

Choosing the Right Spot

If your climate is Calathea-friendly, the next step is finding the right spot for your plant. Calatheas love bright, indirect light. Too much direct sunlight can scorch the leaves, leaving them crispy and brown. On the flip side, too little light can cause the vibrant patterns to fade, resulting in a dull-looking plant.

Outdoors, a spot that receives dappled sunlight or is shaded by larger plants or trees often works well. Think of how they might grow naturally in a rainforest under the canopy. If you're placing them on a patio or balcony, ensure they’re protected from the harsh afternoon sun.

An east-facing spot can be perfect, as it provides gentle morning sunlight and shade for the rest of the day. If you notice the leaves curling or turning brown, it might be an indication that your plant is getting too much direct light.

Soil and Potting

When it comes to soil, Calatheas prefer a well-draining mix. They enjoy moisture but detest sitting in water, which can lead to root rot—a plant parent's worst nightmare. An ideal soil mix for a Network Calathea would include peat moss, perlite, and some pine bark. This combination ensures good drainage while retaining enough moisture for the plant's liking.

If you're planting your Calathea in the ground, amend your soil with organic matter to improve drainage and nutrient content. Raised beds or large containers with drainage holes are also great options for outdoor planting.

Speaking of containers, ensure your pot has proper drainage holes. The size should be big enough to accommodate the root system but not too large, as excess soil can hold water and cause issues. It’s a balancing act, but once you find the right combination, your Calathea will thank you.

Watering Needs

Watering can be a bit tricky with Calatheas, as they are sensitive to water quality and frequency. They prefer distilled, filtered, or rainwater because tap water can contain fluoride or chlorine, which can damage the leaves. If you're using tap water, let it sit out overnight to allow some of the chemicals to dissipate.

When it comes to frequency, aim to keep the soil consistently moist but not soggy. This usually means watering every 1-2 weeks, depending on your climate and the specific conditions of your outdoor space. The top inch of soil should be dry before you water again. Remember, it's always better to underwater than to overwater with these sensitive plants.

During hotter months, you might need to increase your watering frequency. Monitor your plant closely—it will let you know if it needs more water by drooping its leaves, a not-so-subtle cry for help.

Dealing with Pests and Diseases

Like all plants, Calatheas can be susceptible to pests and diseases, especially when grown outdoors. Common pests include spider mites, aphids, and mealybugs. These tiny invaders can wreak havoc on your plant if not dealt with promptly.

Regularly inspect the undersides of the leaves and along the stems for any signs of pests. If you spot any, a gentle spray of neem oil or insecticidal soap can usually do the trick. For a more natural approach, you can wipe the leaves with a damp cloth to remove pests manually.

Fungal issues can also arise, particularly in humid environments. Ensure your plant has good air circulation and avoid overhead watering to minimize the risk. If you do encounter fungal problems, consider using a fungicide or consult a local expert for advice tailored to your region.

Fertilizing Your Outdoor Calathea

Feeding your Calathea can help it maintain its vibrant colors and healthy growth. During the growing season (spring and summer), use a balanced, water-soluble fertilizer every month. Dilute the fertilizer to half strength to avoid overwhelming the plant with nutrients.

In fall and winter, reduce feeding to every two months or stop altogether, as the plant's growth naturally slows down. Over-fertilizing can lead to leaf burn, characterized by brown tips and edges, so it’s always better to err on the side of caution.

Remember, a little goes a long way with Calatheas. They’re not heavy feeders, so you don’t need to go overboard with the fertilizer.

Creating a Cozy Outdoor Environment

To truly thrive, your outdoor Calathea might appreciate a little extra attention to its surroundings. Consider creating a microclimate that mimics its natural habitat. This could mean adding other tropical plants nearby to provide shade and increase humidity.

Misting your Calathea a few times a week can help maintain humidity levels. A pebble tray filled with water underneath the pot can also elevate the surrounding moisture. Just ensure the pot sits on the pebbles and not directly in the water to prevent root rot.

Wind can also be a concern, as it can dry out the leaves and reduce humidity. Positioning your plant in a sheltered area, like near a wall or other large plants, can protect it from strong gusts.

Transitioning Indoors and Outdoors

If your climate doesn’t permit year-round outdoor living, you may need to transition your Calathea indoors during cooler months. This process requires a bit of patience to avoid shocking the plant.

Start by gradually acclimating your plant to its new environment. Move it indoors for a few hours each day, extending the time over a week or two. This gradual transition helps the plant adjust to changes in light and humidity.

Once indoors, find a spot that mimics its outdoor conditions as closely as possible—bright indirect light and high humidity. A bathroom or kitchen can be ideal due to the naturally higher humidity levels.

Final Thoughts

Growing a Network Calathea outdoors can be a rewarding experience if you consider its specific needs and environment. Climate, light, and soil conditions are crucial for its success.
