Calathea is a popular houseplant that is known for its lush, green foliage and spectacular leaf patterning.
The scientific name for Calathea is Calathea spp., and it’s from the family Marantaceae.
Calathea comes in a number of varieties, such as the Calathea Orbifolia and the Calathea Roseopicta, that have different colors and patterns on their leaves.
Proper watering is essential for the health of Calatheas. Overwatering can cause problems such as root rot, yellow or brown spots on leaves, wilting or drooping of leaves, and stunted growth.
To avoid overwatering, it’s important to ensure that your soil drains well and that you water only when your soil feels dry to the touch.
You should also use a pot with drainage holes so any excess water can escape quickly. It’s also helpful to use an appropriate sized pot for your plant.
if your container is too large relative to the size of the plant, then you risk overwatering due to decreased water evaporation from the soil surface.
Check the humidity levels in your home; higher humidity levels cause more frequent watering needs while lower humidity levels need less watering.
Fertilize sparingly to avoid nutrient buildup in the soil which could lead to overwatering.
When plants are overwatered symptoms often include wilting or drooping leaves due to lack of air circulation at root level caused by soggy soils.
Yellow or brown spots on leaves often caused by fungal diseases related to over-watering.
Roots growing out through drainage holes because they are looking for oxygen.
And stunted growth due to roots not being able to absorb enough oxygen as they are suffocating in overly wet soils.
White mold may form on surfaces near the base of an overwatered plant.
This is a sign of potentially severe root rot caused by bacteria and fungi living in overly damp conditions which can eventually kill your plant if not addressed quickly enough.
In order to reverse signs of overwatering cut back on watering frequency until you find one that keeps your soil consistently moist without staying constantly saturated with water.
You should also repot into a smaller container if needed or incorporate additional draining materials like coarse sand or perlite into its mix if necessary (if using indoor pots).
Once repotted make sure not to over-fertilize as this can add salts which can be toxic for houseplants like calatheas.
Resulting in burn marks appearing on their foliage – make sure you always read fertilizer labels before adding them into your mixture.
Last but not least: keep up regular monitoring so you know when it’s time again to adjust watering frequency – never leave guesswork out.
Signs Of Overwatering
Wilting is a common sign of overwatering in Calathea plants. Wilting occurs when the plant cannot absorb enough water, or if it is taking in too much.
When a Calathea has been overwatered, its leaves will start to droop down and appear limp instead of standing upright as they usually do.
This wilting can be caused by an excess of water in the soil which is preventing oxygen from reaching the root system.
The lack of oxygen causes the cells to shrink and eventually die off, resulting in wilted leaves.
Yellowing leaves can also be a sign that your Calathea has been overwatered.
When too much water is present in the soil, it can cause yellowing or chlorosis in the leaf tissue due to an imbalance of nutrients. This yellowing can occur on both new and old leaves.
And indicates that your plant may be suffering from root rot or some other issue caused by too much moisture in the soil.
Foul odors are another indicator that your Calathea may have been overwatered.
An excess of water will create anaerobic conditions which lead to anaerobic bacteria growing, producing foul odors.
These odors will not only come from the soil but could also be emitted by decaying plant matter or even from inside the pot itself.
If your plant is sitting in stagnant water for long periods of time.
Soil Staying Consistently Moist
If you notice that your Calathea’s soil is staying consistently moist without any signs of drying out, then this could be another sign that you have been overwatering it.
You should always check the top 2-3 inches (5-7 cm) of soil before watering your plant as this will give you a better idea if it really needs more moisture or not.
If this area remains wet for an extended period without any signs of drying out.
Then it’s possible you have been giving your plant too much water and need to adjust accordingly with less frequent watering cycles.
Causes Of Overwatering
Using Too Much Water
Overwatering is a common cause of wilting and yellowing of plants.
When the soil is kept wet for an extended period of time, it can cause the roots to become waterlogged, preventing them from receiving enough oxygen and nutrients necessary for healthy growth.
This can lead to root rot, which eventually kills the plant. It’s important to remember that plants need just the right amount of water in order to survive and thrive.
So it’s best to check the moisture level of the soil before each watering rather than following a strict schedule.
Not Allowing Soil To Dry Out Sufficiently Between Watering
If you allow your plant’s soil to stay wet for too long or don’t provide enough time between waterings for it to dry out, you run the risk of overwatering.
This can lead to a number of issues such as root rot and fungal diseases which can be difficult or impossible to reverse.
To avoid this, make sure you wait until at least 2 inches (5 cm) of topsoil becomes dry before adding more water.
Poor drainage can also contribute to overwatering problems as it prevents excess water from draining away effectively, leading it instead accumulate around the roots.
Always make sure that your pot has adequate drainage holes in its base so that surplus water can escape freely after watering your plant.
Use a well-draining potting mix with plenty of perlite or vermiculite added in order achieve better drainage.
Watering On A Schedule Rather Than Checking The Moisture Level Of The Soil
A fixed watering schedule may seem like an easy way to ensure your plant gets enough hydration.
But without taking into account environmental factors such as temperatures and humidity levels, this method often leads people into overwatering their plants.
Instead, it’s recommended that you check your plant’s soil moisture using a moisture meter or simply poking your finger down into the top layer – if it feels damp then skip watering until next time.
How To Fix An Overwatered Calathea
Remove the Plant From Its Pot and Examine the Root System.
Removing the plant from its pot is an important step when determining if a Calathea has been overwatered.
Care should be taken to gently remove the plant from its pot so as not to damage its delicate root system.
After taking the plant out of its pot, it should be examined for signs of root rot or disease.
If any diseased or decaying roots are found they should immediately be trimmed away with sterilized garden pruners.
Prune Off Any Diseased Or Rotting Roots
Pruning off any diseased or rotting roots is essential in helping your Calathea recover from overwatering.
These roots will no longer absorb nutrients and water, instead they will use what little resources the plant has available, leading to a weakened state of health over time.
Trimming away these sections will help promote new healthy growth while also allowing the remaining healthy roots to access more resources from the soil.
Before pruning, make sure that all tools are properly sanitized to prevent spreading any diseases that may already exist on the plant’s exterior.
Repot The Plant In Fresh, Well-Draining Soil
The next step in fixing an overwatered Calathea is repotting it into fresh well-draining soil.
This soil should have good aeration so that excess water can quickly drain away and allow oxygen to reach all parts of the root system.
When selecting a potting mix, try to avoid one with too much nutrient content as this may further encourage overwatering in addition to creating problems like fungal growths due to overly moist conditions.
Allow The Soil To Dry Out Before Watering Again
Once your Calathea has been repotted into fresh well-draining soil, it’s important not to rush back into watering it again right away as this could further promote root rot and other issues associated with overwatering plants in general.
Instead, wait until you feel that most of the moisture has been drained out of the soil before adding any additional water.
This can easily be checked by feeling along various points of the top layer with your fingers.
Then monitor how often you need to water your Calathea moving forward in order to maintain optimal health without risking too much saturation within its environment again in future instances of caring for it.
Monitor The Moisture Level Of The Soil Regularly
Checking and monitoring your Calathea’s soil moisture level regularly is essential for maintaining healthy levels without risking another episode of overwatering it again.
This can be done by simply feeling along different points on top layer with your fingers.
If there is still some dampness present (ie not completely dry) then don’t add any additional water yet – wait until this point dries out before adding more liquid.
Doing this regularly will help keep your plant happy and thriving for many years ahead.
Prevention Of Overwatering
Using A Moisture Meter To Check Soil Moisture Level
A moisture meter is a simple and effective tool for checking the moisture level of the soil in a pot.
It works by measuring the electrical conductivity of water-saturated soil, which then is converted into an estimated percentage of moisture in the soil.
The readings from these meters can provide insight into when it’s time to water a plant, as well as when too much water has been given.
Knowing how wet the soil is will help to prevent over-watering, which can lead to root rot in many plants, including Calatheas.
Water Only When Top Inch Of Soil Is Dry
Calatheas need consistent and even watering, but not too much so they become vulnerable to root rot.
To ensure your plant gets watered properly you should only water it when the top inch or so of soil is dry.
You can check this by inserting your finger into the top inch or two of soil, or if you find that hard to gauge, use a moisture meter instead.
This will help you determine when it needs water and also stop you from giving it too much water which can cause over-watering in Calatheas.
Use A Pot With Adequate Drainage Holes
When planting Calatheas, make sure you use pots with adequate draining holes. This may go without saying but it’s worth mentioning anyway.
Over-watering Calatheas can be prevented by having good drainage holes on your pot.
As this allows excess water to escape so that roots are not continually sitting in wet mud and causing root rot or other problems due to oxygen deprivation from over-saturated soils.
Make sure that any saucers you use under the pot do not collect too much water as this could lead to over-watering if left unchecked.
Consider Size And Type Of Pot Used
The size of pot matters in terms of preventing over-watering your Calathea since smaller pots tend to dry out quicker than larger ones.
Since plastic pots often hold more moisture than ceramic or clay pots they should only be used for plants that need extra humidity like tropical houseplants.
They are not suitable for using with Calathea since they often lead to over-watering due their increased ability to retain water compared with other materials such as terracotta or glazed ceramics.
Therefore careful consideration should be taken when selecting what type and size pot is best for your particular variety of Calathea.
Start small, if possible as this will help ensure less frequent watering cycles along with better aeration for roots which helps keep them healthy.
