Calathea Lancifolia Care in Detail

Calathea Lancifolia Grow And Care Guide

Calathea Lancifolia Watering

Calathea lancifolia likes a humid growth environment, so we must water enough when growing Calathea lancifolia. Especially in hot and dry summer, keep a small amount of water every morning to wet the soil. Water once every 2 ~ 3 days in spring and autumn. In winter, watering should be significantly reduced. Basically, keep the soil slightly dry. Water once every 7 days. Don't let the plants accumulate water.

Calathea Lancifolia Soil

If we want to make Calathea lancifolia lush, the most important thing is a pot of fertile, loose and permeable soil. Only very breathable soil can accelerate the growth of Calathea lancifolia. We'd better mix rotten leaf soil with peat soil and pearl stone in the ratio of 5:3:2,. With this configuration, the soil is not only loose and breathable, but also has good fertility.

Calathea Lancifolia Light

Although Calathea lancifolia likes the illumination of indirect light, it can not bear excessive light, especially the hot sun in summer, which will make the leaves of Calathea lancifolia yellow, dehydrated and even wither. At ordinary times, we must put Calathea lancifolia under the indoor astigmatism environment.

Calathea Lancifolia Temperature

When growing Calathea lancifolia, we must pay attention to controlling the temperature, preferably between 18 ~ 25 ℃, which can be built in a large temperature to ensure the rapid growth of plants as much as possible. If the weather is too hot in summer, Calathea lancifolia should be moved to a cool environment for shade, so as not to bake and dehydrate the plants at too high temperature. In winter, we also need to move Calathea lancifolia to the balcony to keep the plants warm in the sun.

Calathea Lancifolia Humidity

Calathea lancifolia likes a humid growth environment and basically keeps the humidity around the plant at about 80%. Humid environment can promote the growth of Calathea lancifolia plants, so we must often spray water mist on the environment around the plants to moisturize when maintaining Calathea lancifolia. Especially in summer, in addition to watering, spray more water mist to avoid drying.

Calathea Lancifolia Fertilizer

The fertilization amount of Calathea lancifolia should not be too large, especially do not like concentrated fertilizer. If the fertilization is too concentrated, there may be fertilizer damage. During growing, we must apply fertilizer frequently and thinly. In spring, we apply fertilizer twice a month. The fertilizer is basically nitrogen fertilizer, and a little potassium and phosphorus fertilizer can be applied occasionally. However, nitrogen fertilizer will make the leaf markings of Calathea lancifolia more beautiful.

Calathea Lancifolia Pruning

The dry and curly leaves of Calathea lancifolia should be cut off, so as to keep the leaf color green and prevent the dry parts from spreading, resulting in the dry and curly whole leaves. After cutting off the leaves of Calathea Lancifolia, keep healthy leaves and spray it every morning and evening. This will prevent the Calathea Lancifolia leaves from drying up again.

Calathea Lancifolia Repotting

Generally, it should be transferred from April to may in spring. At this time, the temperature environment is more than 20 ℃, which can provide a suitable temperature environment for Calathea lancifolia to take root and survive, and can effectively avoid low-temperature freezing damage and poor growth caused by high temperature. We'd better plant it in a flowerpot with large diameter and shallow depth. It also has good air permeability. We can choose a pottery basin. Then we will prepare peat soil, peat soil and river sand according to 2:2:1, so that it can make Calathea lancifolia grow better. Timely pruning of roots is also one of the precautions for Calathea lancifolia's pot moving and maintenance. After removing the taro from the pot, it is necessary to prune the roots, cut off the rotten roots above, and prune the long roots and old roots to avoid failing to absorb nutrients normally, thus affecting the healthy growth of Calathea lancifolia. Generally, we only replace 1/3 or 1/2 of the soil during Calathea lancifolia repotting, and reserve part of the soil to avoid environmental discomfort of bamboo taro. It should also be watered in time after changing the basin to ensure that it has sufficient water supply, and then placed in a semi shady area for maintenance.

Calathea Lancifolia Pest & Disease Control

White silk disease

  • Symptom
White silk disease is still common in Calathea lancifolia. When Calathea lancifolia has white silk disease, its stem and leaf base will rot near the soil, and then grow white bacteria to spread in the soil, and then cause the disease, wilt and death of the aboveground part. White silk disease appears white in the early stage, gradually turns yellow in the later stage, and finally turns brown. White silk disease mainly occurs in July and August every year, especially when the soil moisture is too high and the soil is barren.
  • Control method
When white silk disease occurs, disinfectants can be added to the soil planted with Calathea lancifolia for disinfection, and all infected soil and diseased plants shall be removed and destroyed when the sclerotia is not fully formed. During planting, attention shall be paid to ensure the air permeability of plants.

Leaf spot

  • Symptom
The main symptom of leaf spot disease is to produce small spots on the leaves, and then gradually expand. The onset time of leaf spot disease is not fixed, and it may occur all year round. The peak period of leaf spot disease is from September to October and next March, which will dry the leaves of Calathea lancifolia.
  • Control method
We should apply appropriate amount of fertilizer to the soil to enhance the resistance of plants, and timely destroy the diseased parts and Calathea lancifolia to prevent re infection.

Calathea Lancifolia Propagation

Calathea Lancifolia Propagation from Cutting

Calathea lancifolia propagation from cutting is also a kind of propagation mode of arrow feather bamboo taro. Although it is not as widely used as ramet propagation, it is also an important propagation method of arrow feather bamboo taro. Cutting propagation generally uses the tender shoot at the top of the plant as the cuttings, and the length of the cuttings is about 10cm to 16cm. And according to the actual blade size, keep about half of the blades. For Calathea lancifolia cuttings, we can first treat them with naiacetic acid. After the treatment, insert the cuttings into the seedbed, pay attention to maintaining the row spacing, and cover them with film after planting. The management method of cutting propagation is the same as that of ramet propagation. The best temperature for calathea lancifolia propagation from cutting is 20 ℃, and the cuttings will take root about 40 days after cutting.

Calathea Lancifolia Propagation from Division

Division propagation is more common for Calathea lancifolia. Cutting propagation is less than ramet propagation. The best propagation temperature of Calathea lancifolia is about 20 ℃. If ramet propagation is carried out indoors and the temperature and humidity are well controlled, ramet propagation can be carried out throughout the year. What are the steps of Calathea lancifolia dissemination from division? First of all, we should cut the root block with stems, leaves and buds with a knife. For family planting, we can directly plant the cut root block. We must pay attention to the maintenance of planting temperature and humidity when we reproduce in Calathea lancifolia.
