Calathea Information:

Calatheas live in tropical rain forests. In the wild they populate the lowland rain forests of Brazil and Africa. They live on the forest floor under the tree canopy where they are protected from strong direct light and heavy winds.

The water in their native environment is soft, acidic rain water filtered through the forest floor. It’s low in minerals. This is a BIG deal for Calatheas. If you water them with regular tap water chances are they won’t like it.

The forest have mostly stagnant air without much breeze or temperature changes. These plants are happiest in still air at 65 to 75 degrees F with humidity of 50 to 60%.

Not much changes in the natural world they are suited for. They don’t adjust well. If you try to challenge them with conditions outside their comfort zone Calatheas will complain loudly with poor foliage, drooping leaves and rotted roots.

Plants in the Calathea genus are in the family Marantaceae (arrowroot family). Recently about 200 of these plants were moved to the genus Goeppertia. For more on the Classification of calathea plants read this. For now you will find all your favorite Calathea plants tagged as Calatheas in plant shops and online shops.

Calatheas are similar to Maranta plants However, They have differences in their coloration patterns and leaf shapes. Marantas can also trail and make an interesting hanging plant.

Calatheas exhibit the praying hands reaction to light. But Maranta Leuconeura is the original prayer plant.

Calatheas grow as upright bushes. They make great table top plants, windowsill plants or bushes for a boring corner. The foliage is exciting and dramatic. Wherever you put them calatheas will steal the show.

Growing habits:

A huge variety of exotic leaf patterns and colors are available from this genus. Most Calathea types have a low bushy profile. Several of the varieties grow to to 24 inches tall or so.

When you choose one they will normally be immature plants. Be sure you know before you buy how large the plant gets.

Calatheas grow from rhizomes that tap into the rich soil nutrients and keep them well fed. We propagate mature calatheas by rhizome and root division.

Beware dividing a very young Calathea. They may not recover from the shock. Let them grow up and then divide them at repotting time every couple of years.

Calathea Care:

Once you learn the language of plants it’s pretty easy to see when they have a problem.

Persistent curling brown edged leaves, drooping and fading foliage are clues to their unhappiness.

However, It’s normal for the leaves of an established Calathea to have a brown edge or two. Thickly planted bushes may have dead leaves occasionally in the center of the plant.

Simply trim off the brown with clean sharp shears to spruce the plant up. Cut off dead leaves at the soil line and remove to clean up the plant. This also helps avoid fungal infections, pathogens and pests.

They are often plagued with fungus gnats. Spider mites can be a problem if they get a foothold in your Caltheas.

Instructions

Soil Preference:

  1. Calatheas enjoy a light well draining soil. filling small pot with soil for cutting
  2. A mix of potting soil and perlite will keep the roots happiest.
  3. Our mix for this plant is 30 % potting mix, 30% succulent mix to 30% perlite.
  4. A heavy soil potting mix is not recommended for these plants.

Pot Size and Type:Calathea Medallion

  1. Calatheas grow from rhizomes. And they grow new offshoots to the sides of the mother plant.
  2. This means they will fill a pot out as a wider plant eventually. Quite a nice table top centerpiece.
  3. Some of them can trail and be used for a hanging plant as they grow.
  4. Calatheas will grow to the size of its pot. If you leave it to grow as a grouping in one pot you will need to find a pot that is shallower and has a wider circumference. They do not like to be overly root bound.
  5. If you want to encourage faster growth choose a pot about 2 inches wider in diameter than the current pot.
  6. Any well drained pot can be used. It MUST have excellent drainage.
  7. Terra cotta pots are not recommended. They will wick too much water away from the soil.
  8. Repot every second year or when roots come out the drainage holes on the pot bottom To the next pot size up.
  9. Don't jump to a huge pot from a small one unless you wish to encourage faster growth. Just go to the next size up pot.
  10. For Calatheas self watering pot systems work well. (linked above). They control the watering for you and help avoid root rot, overwatering and under watering.
  11. Calatheas enjoy evenly moist soil so self watering systems help here.

Lighting:

  1. Calatheas all enjoy indirect light for best leaf variegation and optimal growth.
  2. Different species are fussier than others but as a general rule if the leaves fade move to a less bright area and see if that helps. Too much light can fade the leaves and crisp the leaf edge.
  3. It will tolerate lower indirect light but the plant may grow more slowly. Leaf variegations may not be well expressed.
  4. Shield this plant from strong direct light in summer south and west sunny windows. The leaves will burn and the colors will fade. Look for dry brown spots on the leaves and curling brown edges. If you see them move the plant to lower light.
  5. Tip: Window sheers or blinds can offset some brief periods of high direct light.

Watering:

  1. Calatheas are VERY sensitive to the water you use. These plants thrive on soft acid water. PH or 5.5 to 6.5 recommended. Hard water high in minerals TIPS: Let your tap water sit for 24 hours to allow any chemicals to dissipate. Use Filtered or distilled water to eliminate problems with minerals.
  2. Water your Calathea when the soil is dry down an inch or so. Calatheas enjoy even moisture in the soil. But never let it sit in soaking wet potting mix. Use your moisture meter to ensure the soil is evenly moist around the pot. And don't water until it verges on dry.
  3. If your calathea leaves start to roll up and curl, the plant droops or the edges turn brown suspect watering problems or low humidity.
  4. Under watering can show all the symptoms listed above. Adjust your watering or soil mix to accommodate.
  5. Over watering will end in root rot, grey mold on the leaves, algae growth on the soil and fungus gnats or other pests moving in.
  6. Try a watering schedule of once a week. But do not water if the soil is wet. Alternately, Do not let the soil dry out completely.
  7. Watering is best done on a regular schedule so the plant is not over or under watered. Both can cause stress.
  8. These tropical plant enjoy humidity of 50 to 60%. They can go higher to 70% but never let them fall under 40 % or the leaves will crisp.
  9. In dry climates this plant will thrive with a humidifier nearby. Or set it in your kitchen or bathroom. Pebble trays work well for Calatheas.
  10. More humidity tricks: Set the plant on a pebble tray with water not touching the soil for added humidity as necessary. Grouping plants together will provide more humid conditions.
  11. In dormant winter months reduce watering to when the soil is dry down 2 inches .
  12. Never let this plant get wet feet. If the soil is compacted the bottom of the soil can remain wet which encourages, grey mold on the leaves, root rot and Fungus Gnats. If you see yellow leaves or brown curling leaf edges you are probably overwatering or Inconsistently watering.
  13. self watering planters are a good choice for calatheas. They remove many of the watering problems listed here.


Humidity TIPS:


Keep the humidity Ideally between 50 and 60 %. To know your humidity keep a hygrometer by your plants. They are cheap and SO worth it. To increase humidity try these things.

  1. Calatheas are happy at 50 to 60% humidity. Although they can tolerate higher, do not let it drop under 40%.
  2. I use an inexpensive hygrometer to monitor the room temperature and humidity levels near mine. It is cheap and so helpful!
  3. In dry climates this plant will thrive with a humidifier nearby. Or set it in your kitchen or bathroom.
  4. Frequent misting on a regular daily schedule will help keep humidity up when all else fails. However, misted leaves can be hosting spots for bacteria and fungi.
  5. Set the Calathea plant on a pebble tray with water not touching the pot bottom for added humidity as necessary.
  6. Grouping plants together will also provide more humid conditions as they respire and evaporate.

How to Fertilize:

  1. Calatheas require a regular fertilizing schedule.
  2. Apply a good quality fertilizer monthly through Spring and summer.
  3. Decrease feedings by late Fall and allow your Calathea plant to rest through the winter months.
  4. Look for brown spots on the leaves of your plants. This may indicate an over concentration of salts in the roots from over feeding. It can burn the leaves.
  5. The remedy is to set the plant under a faucet of water and let the water run through for 10 minutes or so. Allow the pot to Completely drain. Discontinue fertilizer until the plant recovers.

Temperature:

  1. Optimal temperatures for Calatheas are 65 degrees F. to 75 degrees F.
  2. Calatheas are sensitive to cold drafts from windows and doors.
  3. In winter, beware heat vents blowing on your plant leaves. Calatheas cannot tolerate uneven heating, or drying heat vents or drafts.

Pruning and Training:

  1. Sharp Hand pruners are preferred for pruning. They will give a clean cut that will heal quickly.
  2. Cut off the leaves of Calatheas at the soil line.
  3. Pruning is usually done to shape the plant or keep it small.
  4. Calatheas grow wider rather than taller. This makes them ideal table top or window sill plants.

Leaf Care:

  1. For the best care leaves enjoy occasional washing.
  2. This helps keep the stomata (leaf pores) open for plant respiration.
  3. Healthy leaves with a good clean surface are most able to resist pests.
  4. Dusty leaves will starve the plants of water exchange through humidity.
  5. Hand Wash the leaves monthly with water.
  6. You can also use a shower to clean off a calathea. Beware the water temperature. Keep it room temperature to avoid shocking the plant.

Pests:

  1. All plants get attacked by pests. Calatheas are especially susceptible to spider mites.
  2. Stress by longterm poor watering practices, poor light, extreme temperatures and soil conditions are contributors to pests. Fungus gnats will set up house in the soggy soil of an overwatered plant.
  3. Washing the plant leaves occasionally will help keep pests from establishing themselves on the plant.
  4. Spider mites are the biggest problem for Calathea plants. Watch for the webs. Treat immediately and continue for two weeks or more to remove the next generation of spider mites after the adults die. Eggs attach to the leaves and cannot be washed off easily.
  5. Mealy bugs, scale, thrips and whitefly are also common houseplant pests you will see in a stressed Calathea.
  6. Read our post on How to get rid of aphids and other pests with our homemade pesticide soap recipe or neems oil.spraying Pothos with DIY Pesticide soap
  7. To minimize the possibility of pests be sure to check all nursery plants before bringing them home. Carefully examine the top and bottom of the leaves.
  8. Do NOT purchase plants with signs of pest damage or disease.
  9. Quarantine all new plants until you are sure no pests live in them.

How to Propagate Calatheas:

  1. Propagation is best done through root and rhizome division.
  2. Seed propagation can be done but the seeds can be difficult to source.
  3. Dividing a calathea is easiest when repotting it in spring or summer.
  4. Un-pot the plant gently. Look at the root system. If the plant is mature you should see a natural parting in the leaves and roots. This is the two plants growing together.
  5. Each plant section will have its own rhizome. This is going to look like the stem growing straight down with roots coming off them.
  6. Gently pull apart the two rhizomes to separate them. If the roots are heavily intertwined cut them as necessary with sharp sterile scissors or small pruners.

Pot the two plant sections in separate pots. In 2 to 4 weeks the divisions should be settled and growing.

Non Toxic Plant:

  1. All calatheas are non toxic to humans and pets. Still it not recommended to chew any houseplant.
  2. Biting or swatting are not good for the health of the plant.
  3. Also you don't know what chemicals or pathogens are in the soil or fertilizers you use. So best practice is to keep houseplants away from pets and kids.
