Siam Tulip was originally used for cut flowers, and now many flower friends ask how to care for Siam Tulip at home. We'll talk about the Siam Tulip care when we growing it at home today.
The leaves and flowers of Siam Tulip are all yellow, which may be caused by improper watering, so the rotting roots need to be cut off and replanted in the soil. In case of excessive fertilization, a lot of water needs to be irrigated to dilute the fertilizer. If frostbite is caused by low temperature in winter, the frostbitten branches and leaves need to be cut off and the temperature should be controlled above 5℃. The following are Siam Tulip care for leaves and flowers yellowing.
If Siam Tulip is watered too much and the pot is filled with water, it is easy to fester the roots and turn the leaves and flowers yellow. Siam Tulip can be dug out of the soil, and then the rotting roots can be cut off and replanted in the soil.
Although Siam Tulip has a high demand for nutrients, blind fertilization will also make the leaves and flowers of Siam Tulip turn yellow. If it is caused by fertilizer damage, a large amount of water needs to be poured into the soil to dilute the fertilizer in the soil, and it can also be directly replaced with pot soil for cultivation.
The cold resistance of Siam Tulip is not strong. If the temperature is lower than 5℃ in winter, it is easy to get frostbite of Siam Tulip, which will make the leaves and flowers turn yellow. It is necessary to cut off the frostbitten branches and leaves, and then control the temperature above 5℃ to avoid more serious situations.
Siam Tulip is damaged by red spiders, aphids and other diseases, which will also make the leaves and flowers of Siam Tulip turn yellow. It is necessary to cut off the sick branches and leaves, and keep the environment ventilated. A proper amount of topdressing potassium compound fertilizer can be applied, and then spray dichloral, dimethoate, dichlorVOS and other agents to Siam Tulip.
Siam Tulip needs to change the soil during the winter, choose fertile, breathable and good drainage of slightly acidic soil; And to reduce the amount of watering, water every 10 ~ 20 days or so; Move to indoor maintenance in November every year, and the temperature can not be lower than 10℃; Put it in the sunlight scattering environment for maintenance, and the illumination time should not be less than 5 ~ 8 hours. The following are Siam Tulip care for growing in winter.
During the winter, replace the soil first, and we can use river sand and Garden soil and sandy soil humus according to the appropriate proportion of 4:3:3 mix, making it have the fertile, breathable and good acidic soil drainage for the winter. Avoid nutrient deficiency, which will cause blade yellowing phenomenon.
In winter, Siam Tulip is in dormant period, and the growth needs not much water. According to the actual situation, reduce the amount and times of watering. Water can be watered every 10-20 days or so, so as to avoid water accumulation.
Plants should be moved indoors for maintenance in November every year. The growth temperature should not be lower than 10℃, and the suitable growth temperature should be controlled between 20 and 25℃. Too low temperature will cause freezing damage to the roots, which will affect the healthy growth of Siam Tulip.
Siam tulip is a plant that likes to grow in a warm and humid environment. In winter, it needs to receive about 5-8 hours of sufficient light every day. When the light is insufficient, incandescent lamps can be used to supplement the light, but the phenomenon of yellowing and withering of leaves should be avoided due to direct sunlight.
