How to Grow and Care for Calathea Orbifolia

The round-leaved calathea (Geoppertia orbifolia) is still most often referred to informally by its prior botanical name, calathea orbifolia. The silver-green stripes on its luxuriant, large leaves make it a bold statement plant, but it's somewhat fussy and can be high-maintenance.

However, this tricky plant has lots going for it if you're willing to put in the extra effort.Calathea orbifolia is fast-growing, pet-friendly, lush, and eye-catching.

Calathea Orbifolia Care

These plants need plenty of attention to thrive, and trying to keep calatheas alive can be a challenge, even for the most experienced plant parents. One of the reasons they're often nurtured in greenhouses is their need for a warm, humid environment.

If you can mimic the tropical conditions they love, you'll get to appreciate the beauty of the calathea orbifolia in your own home. Here are the main care requirements:

• Place the plant in bright, indirect light.
• Fertilize monthly during the growing season with a balanced liquid fertilizer.
• Provide a high humidity, warm, draft-free environment; think moisture-laden air, shady positions, and balmy temperatures.
• Prepare a loose potting mix that retains moisture.

Light

It's all about encouraging lush, healthy-looking foliage with a calathea orbifolia, and offering the right diffused light is one of the keys to success.

Direct sun results in ugly brown spots, leaf scorch and fading patternation. However, if the light conditions are too low, the leaves won't look their fullest or healthiest. Rotating the plant every month helps to promote balanced growth too.

Soil

Calathea orbifolia has fragile, petite roots, so a fine, loose, and lightweight potting mix works best. Because these plants need plenty of moisture, you want to opt for something that has good water retaining qualities.

Mixes designed for African violets work well. If you want to make your own, opt for a slightly acidic mix. Something like one part peat moss (or, as a sustainable alternative, coconut coir), one part perlite, and one part vermiculite.

Make sure the pot has adequate drainage holes. While Calathea orbifolia likes consistent moisture, water-logging results in root rot.

Water

Watering errors are where lots of first-time round-leaved calathea owners go wrong. Getting the balance right can be tricky, as too much watering leads to root rot and the eventual death of your plant.

Always check the top couple of inches of soil with your finger. If it feels damp and soil comes off on your finger, wait a couple of days and check again. If the soil feels dry, it's usually time to water. Use a moisture meter if you're not sure.

While they need consistent moisture, these plants can't tolerate soggy roots. The little and often approach works best, and watering from the bottom helps moisture reach the roots and the center of the pot.

Watering from the top often results in the water draining right down through to the bottom. Make sure to check the soil after a few hours. If the soil is moist right up to the top, drain any excess water from the saucer or tray below the pot.

Using distilled or filtered water or tap water left out overnight helps prevent the crisping leaf edges or yellowing leaves that some of the problematic minerals can cause.

Temperature and Humidity

These plants don't appreciate chilly temperatures, draughts, or blasting heating or A/C. They need consistent warmth and humidity. Temperatures below 60 degrees are problematic. Maintain average home temperates between 65 and 75 degrees.

Round-leaved calathea are good candidates for bright, warm bathrooms. Humidity levels above 50 percent are needed to keep your plant looking healthy, although 60 percent humidity is more likely to help your plant to thrive.

If your house doesn't offer this naturally, consider using a humidifier, placing your plant in a large terrarium or under a glass dome, or using a tray of pebbles with water in the base under your plant. Regular misting might help to improvise humidity levels too.

Fertilizer

Although applying a weak dose of nitrogen-rich fertilizer around once a month during the growing season can help promote lush, healthy foliage, don't go overboard. Too much or too strong fertilizer can scorch the leaves.

Pruning

Calathea orbifolia doesn't have a high-maintenance pruning schedule. Just remove dying or dead leaves by cutting the stems to around an inch above the soil line. This helps direct energy to new and healthier growth.

Always use clean pruning shears or scissors to reduce the risk of transferring fungal diseases.

Propagating Calathea Orbifolia

Propagating calathea orbifolia can be challenging but is not impossible. Because it's done by root division, you'll only be able to do this if you have a large, healthy, mature plant.

For best results, consider propagating at the same time as you're repotting your plant. Where possible, stick with late spring or early summer propagation when temperatures are at their warmest and growth is most vigorous.

Here's how to propagate your round-leaved calathea.

1. Gently remove the plant from the pot.
2. Usually, you'll see baby clumps growing off the side of the mother plant. These are what you want to break off, keeping a tuber root and one leaf. Gently separate the roots, trying not to break them.
3. Don't delay in planting the divided baby section in a loose, well-drained, sterile potting mix. The delicate roots shouldn't be left exposed for too long,
4. Keep the new plant consistently moist but not saturated.
5. Cover the division with a zip-lock plastic bag for a few weeks to help retain humidity and moisture levels.
6. After around three weeks, you can remove the bag once you notice new growth.

Potting and Repotting Calathea Orbifolia

If you see the roots starting to poke out the pot's drainage holes, this is a sign repotting is on the cards.Calathea orbifoliaisn't a fan of having its delicate roots messed with, so only repot when you really need to and be gentle to minimize the chance of transplant shock.

Select a pot around two to three inches larger than the original one, and don't worry about getting all the old soil off the rootball. It's better to fill around whatever original potting soil comes with your rootball instead of trying to replace it all.

Common Pests

Spider mitesare fans of the foliage of calathea orbifolia. However, they prefer a low humidity environment, so if you're spotting these pests, it could be a sign that you need to offer your plant a more humid climate.

Common Problems with Calathea Orbifolia

As you might expect from a challenging plant like the round-leaved calathea, it can be prone to a few issues if it doesn't get the right care and attention. Some things to look out for include:

Leaves Turning Yellow

Overwatering is one of the most common problems for the calathea orbifolia and a sign you might be making this mistake is the stunning leaves turning yellow.

Curling Leaves and Brown Tips

If you aren't giving yourcalathea orbifoliaenough water or the humidity levels aren't high enough, the leaves can start to curl, and the tips can turn brown. However, older leaves often naturally develop a bit of browning on their tips, so it isn't always something to panic about.

These symptoms can also signify that your plant is getting too much intense exposure to sun. To prevent sun scorch, always opt for a position with dappled rather than direct light.

Drooping or Dropping Leaves

A bit of leaf drooping during the day can happen even with the healthiest of round-leaved calathea. If they perk up again at night, it's usually nothing to worry about. However, persistent droop or leaf drop can be a sign that you need to offer your plant more water and humidity.
