Calathea Freddie Care

Calathea Freddie Care involves watering it thrice a week and misting it often. It requires bright, indirect light and about 70% humidity for healthy growth. The optimum soil pH for this Zebra plant is 6.5. It prefers a temperature range of 18-24ºC. The recommended growth zones are 10 and 11.

Calathea Freddie Watering

The watering schedule for this mini plant is a little tricky than the other common houseplants. This peep does not want to be overwatered but also loves moist soil. There is a thin line between Calathea Freddie watering requirement and exceeding the water limit. It is better if you let about 75% of its soil dry before you water it again. You can use the rule of thumb to check its dryness. All you have to do is inject your index finger 2 inches deep into the topsoil and check if it is already dry. You should always pour the water at a moderate to slow pace, so let it drain easily through its soil to the drainage holes. This will prevent the plant from standing water and from getting root rot.

Its watering needs depends a lot on the climate and humidity levels around it. During the growing seasons, you must water it about thrice a week. This watering frequency must be cut down to only once a week during winters when the plant is pretty much dormant. Yellowing of its leaves indicates overwatering, while brown leaves mean that the plant is being under-watered. You should regulate the watering schedule as per the signals.

Soil Requirements

Calathea Freddie prefers to be grown in rich, loose, and slightly acidic soil. The pH of the soil must be kept at 6.5. If you have a neutral soil mix, you can increase its pH by misting the plant with a little vinegar. You should be very careful with its quantity because its excessive amount can burn the roots. Add only 1-2 drops of vinegar to a gallon of water, and keep misting the plant with it.

Concinna plant grows best in well-drained soil. You can use a potting mix that has two parts peat moss and one part perlite. These two ingredients not only increase drainage of the soil but also increase its aeration. More drainage means more space in soil, so excess water can flow out of the pot. Better aeration means more oxygen can flow through the roots, so the roots can breathe and grow healthier. For best results, you can also place pebbles below the soil; it will further increase the draining capacity. However, you should only add the recommended amount of perlite because increased drainage than the required level will do more harm than good.

Calathea Freddie Light Requirements

Calathea Louisae Freddy has light-green colored foliage that shines in moderate light conditions. This plant must be provided with bright, indirect light. Six hours of light exposure per day is recommended for the lush growth of its foliage. This gorgeo suits best in an east, north, or west-facing window. However, a south-facing window might not be good for it. Because when a plant is placed on a window sill facing south, it receives direct sunlight. Direct sun is not beneficial for a plant; it is harmful. The direct sun scorches the leaves and fades their color. This is why you should be really careful with the placement of this plant. If you were planning to grow it outdoors, protect it from direct sun rays by placing it under shade cloth.

Temperature Requirements

This Zebra Calathea plant is from tropical regions. That is why it prefers to be placed in a warmer room where the room temperature remains in an average range. It prefers a temperature range of 18-24ºC. This temperature range is normal in tropical homes. However, if you live in a colder region where the temperature drops below this, even in months other than the winters, you should place a radiator inside the rooms to regulate the temperatures around this plant so that it does not get chilly injuries.

Never let the temperature fall below 15ºC, because below this temperature, this plant is more susceptible to chilly injuries. Also, it should be kept in mind that a chilly injury can even kill a plant, so you better be taking good care of this peep if you live in a colder region. This gorgeous plant should also be kept away from drafts. If you have a radiator or an air conditioner in your room, do not place this plant near them. The hot or cold drafts can damage its vibrant foliage.


Tropical plants mostly grow in the rainforests, where there are surrounded by many different plants and trees. All these plants are grouped; their transpiration rate adds up, and so the humidity levels around them are always high. This is why tropical plants always love high humidity levels. If you grow a tropical plant inside your home, you have to maintain the humidity levels around it. Calathea Freddie is also a tropical plant that loves a high amount of moisture in the surrounding air. The humidity around it must be kept above 70%. This level is higher than the normal household humidity. That is why you should try other ways to increase the humidity levels inside your home. You can do so by either placing this plant over a pebble tray.

This helps because when water evaporates from the pebbles, the moisture in the surrounding air increases. This way, the humidity around it is compensated. Another way to increase humidity around this plant is to mist it often. Misting always helps, but keep in mind that do not spritz this plant directly; always mist it from bottom to top. Installing a humidifier inside the room is also a way to increase and regulate the humidity level. This way might cost a little more than the others, but it is the ultimate solution.


Calathea Concinna Freddie is not a foodie. It does not need to be fed every now and then. It needs to be fertilized every four weeks in the growing season. This includes the months from April to August. In winters, this plant goes dormant, and its growth rate slows down. During these months, it does not need any additional nutrients for growth. That is why it is better if you cut down its feeding frequency in this resting period.

You can use the common houseplant fertilizer for Calathea Freddie. Common houseplant fertilizer contains all the necessary nutrients for this plant. However, this fertilizer is a bit stronger than the need for the Zebra plant. You should be diluted before fertilization. It is better if you dilute it to 1/4th of its strength. You can do so by mixing 1 tablespoon of fertilizer with one gallon of water. Excessive fertilizer can harm the plant. If you see any yellow edges around the leaves of this Calathea plant, cut down its feeding. It is a sign that you are over-feeding your Calathea Louisae Freddy.

Grooming and Pruning

Many people fear that if they prune their houseplants, it will damage their foliage. However, this is not true. Pruning is actually necessary for the healthy growth of a plant. It gives the leaves more space to grow and saves the plant from spending extra energy and nutrients on the dead, old leaves. You should always prune your plant before the growing season. Once you remove the old leaves, new buds can easily grow and bloom. All you have to do is to take sharp shears and cut the yellow leaves off the branches.

If the yellow leaves are more common in the interior portion of the plant, it is actually a sign of some problem. It can be due to lightning, watering, fertilizing, or temperature issue. Disinfecting and sterilizing the pruning shears before pruning your plant is most important. If you do not disinfect them, your plant may get several dangerous bacterial or viral infections.
