Poinsettia has more exquisite requirements on the soil. In addition to the fertile soil, drainage water is good, but also chooses no pollution, no peculiar smell of the soil. When we grow and care for Poinsettia, we can use perlite, peat soil, ceramsite mixed into cultivation soil, and can make its flowers out more bright.

2. Light and temperature care for growing Poinsettia

Poinsettia is a subtropical plant, which likes to grow under the sun. When we grow and care for Poinsettia, sufficient light is given to its stem and leaves during the growth process, it can promote the rapid growth of the stem and leaves. Usually, Poinsettia should be placed at 18 ~ 25℃.

Poinsettia's roots are sensitive to water, so they should not be watered in large amounts at ordinary times. When we grow and care for Poinsettia, it is best to use the soil moisture in the state of being wet without water, which can prevent the root fester of the plant, make the plant leaves yellow and wilting to reduce the ornamental value, and master different watering frequencies according to different seasons.

4. Fertilizing care for growing Poinsettia

Usually Poinsettia likes nutrients, and every time we turn the pot and changes the soil for sowing and reproduction, we need to apply sufficient base fertilizer to the soil, which can be used as the base fertilizer of decaying organic fertilizer or horseshoe.

After changing the pot, when we grow and care for Poinsettia, to ensure that the plant receives sufficient moisture and light, promote its branches re-germination, the new half lignified branches can be cut cuttage, and can be appropriate pruning plant type, so that the old branches evenly distributed. If not pruned, the heart should be picked 2~3 times to ensure plump plant shape.

The basin soil is dry and wet

Spring is the season for growing Poinsettia, so make sure you get plenty of sun, and water, too. To ensure that the pot soil is dry, see wet, if too much watering, pot soil for a long time in the wet state, poor root growth, easy root rot. But when we grow and care for Poinsettia, if the basin soil is dry for a long time, the root is easy to dry, leading to plant water shortage.So watering to see dry watering, see wet stop.

7.Growing Poinsettia care in summer

Avoid high temperature exposure

Poinsettia is not resistant to high temperature and scorching sun, and the temperature in summer should not exceed 28℃, otherwise the growth will not be good. When we grow and care for Poinsettia, we should place it below a half shade environment, ensure adequate moisture supply, often spray it all around when temperature is higher, strengthen ventilation, in order to reduce temperature. If the temperature is higher than 28℃, the growth of Poinsettia stagnates, and fertilization should be stopped, and then resumed after the temperature drops.

Pay attention to the temperature control

At the end of autumn, the temperature decreases, and attention should be paid to temperature control. When we grow and care for Poinsettia, the plants should be moved to indoor maintenance in time, and the indoor temperature should be controlled at about 20℃.

9. Growing Poinsettia care in winter

Temperature control

Poinsettia is not hardy, and flowering in early winter should be kept at 15 ° C to ensure adequate light and water supply. When we grow and care for Poinsettia, insufficient temperature will affect the flowering, and the leaves will appear yellow and fall off the phenomenon, the formation of foot, affecting the ornamental.
