How to water poinsettia (how often) poinsettia overwintering

A variety is a very high-end flower in terms of its name. After all, such a name is very rare, so it must be very authentic red for poinsettia to be able to evaluate such a name, so when we treat such plants, we also need to plant in a very rigorous way, so that we can live up to the name of poinsettia.

How to water poinsettia

1. Watering according to the dry and wet condition of poinsettia basin soil

Poinsettia needs a lot of water throughout its growing period, so it is necessary to check more and water it frequently. If the substrate is too dry, it is appropriate to water more. Usually the pots should be watered when the soil is dry. Don't water too much when watering until there is water flowing out from the bottom of the basin. But avoid watering "half waist water", that is, wet and dry on the basin soil, it is easy to cause the abnormal phenomenon of root growth upward.

2. Watering time of poinsettia

Poinsettia seedlings should be watered in the evening to promote their growth.

The growing season of adult plants is generally watered in the morning, and can be watered around noon in winter, when the water temperature is close to the air temperature, which will not stimulate the plant and try to avoid watering when the sun is strong.

3. Points for attention in watering poinsettia

If it is not watered for a long time, causing the pot soil to be too dry and the plant wilting, do not immediately pour water. The usual practice is to put the flowerpot in a cool place with high humidity, pour a small amount of water, and increase the amount of water as the plant gradually returns to a straight and straight state.

After the summer high temperature season watering, do not expose to the sun, if the sudden exposure, the soil water evaporation is accelerated, the plant will appear physiological water shortage phenomenon, no matter how much water can not be saved.

When watering, insist on watering more in small pots and less in large pots. Small basin soil is less, water content is correspondingly less, easy to lack of water, watering adhere to the principle of a small number of times. After watering enough water in a large pot, it will take a long time to dry, especially small seedlings planted in large pots.

Poinsettia overwintering

1. Control the curing temperature of poinsettia

When the outdoor temperature drops to 15 ℃, poinsettia can be moved indoors and a protective film can be added at night. The temperature is controlled at 15-25 ℃. If the temperature at home is low, you can turn on the air conditioner to increase the temperature. If the temperature is too low, the leaves of poinsettia will curl and fall off. When the temperature is below zero, the color of the leaves will soon appear white pulp and will breed mold. Be sure to protect the green leaves and avoid the phenomenon of "losing your feet" (the leaves under the branches wither and fall).

Poinsettia should enter the room at the right time

Do not enter the house too early, or it will lead to futile growth, in the north in late October and in the south in early November. After moving to the room, you should regularly ventilate and replenish the light, or put it in a well-ventilated place, and the indoor humidity should not be too large, so as not to cause fungal infection.

3. Prevent the freezing injury of poinsettia

Before the beginning of winter, cold resistance training should be carried out: stop nitrogen fertilizer in autumn, increase light, and reduce shade. In addition, in early October, streptomycin was sprayed once a week, three times in a row, and then once a month, which could effectively prevent diseases and insect pests.

4. Pruning poinsettias is prohibited

After the beginning of winter, it is the flower bud differentiation period of poinsettia, do not prune at this time, even if the branches and leaves are too dense, because a little carelessly will not cut off the flower buds, affecting flowering. In addition, phosphate fertilizer can be applied to promote flower bud differentiation.

Can poinsettia be kept indoors?

Keeping it indoors is not recommended. First of all, although it does not release poisonous gases, the plant itself is poisonous, and the white liquid it contains may irritate the skin, causing redness, swelling or allergies, and if it eats its stems and leaves by mistake, serious ones may die. And because its color is very bright, it is easy to attract children and pets, and it is very easy to eat by mistake.

In addition, although this plant is a kind of short-day light, it likes light very much, and it generally does not grow very well in the bedroom where the light is weak, so it is best not to put this plant in the bedroom.

In addition, the process of plant development and flowering requires a long period of watering, fertilization, temperature control and other treatment, which is not easy to operate in the bedroom, and sometimes the bedroom will be very messy.

Considering the above reasons, it can be said that this kind of plant is not suitable for the bedroom, but when we say no, we don't mean not at all. If you want to put it in the bedroom, you need to pay attention to some problems.
