How to care for Poinsettia

Poinsettia, the color is very bright, bright red flowers with emerald green leaves, especially beautiful. Poinsettia is often used as an ornament flower. How to care for Poinsettia when we grow it? Let's look together

Poinsettia care for lack of color

Poinsettia's lack of color may be caused by delayed leaf discoloration, light, lack of water, and uneven fertilizer. It is difficult to ensure that plants turn red unless they have the right amount of light, water and a balanced supply of fertilizer. Give the plant plenty of light, water and fertilizer before the leaves turn red. The following are details of Poinsettia care for lack of color.

Poinsettia may not be red because the leaves don't turn red at the time of the year. Poinsettia leaves tend to turn red in the fall. When we care for Poinsettia, if it is not the autumn time or just entered the autumn, it is the wrong time because the leaves are not red. At the beginning of autumn, the leaves do not change color so quickly. It takes another 7 to 15 days for the leaves to gradually turn red.

Light can affect the color of the leaves, and the Poinsettia flowers are not red, indicating that the light duration is too short. When we care for Poinsettia, if the light is too short, the plant can't store enough nutrients and anthocyanins to change its color. Before the Poinsettia leaves turn red, if there is no sufficient sunlight, the anthocyanins in the plant body are relatively small, which will affect the leaves to turn red.

Water affects the color of the leaves. Poinsettia flowers need a proper amount of water for their growth. Without enough water, the plant's stems and branches can't grow properly, limiting leaf growth. When we care for Poinsettia, if without proper moisture conditions, the leaves will grow relatively small, narrow leaves are not easy to red, mostly green.

Fertilizer also affects the color of the leaves. When we care for Poinsettia, poinsettia needs to have a proper amount of fertilizer and a balanced application of fertilizer during the growth period, using nitrogen and phosphorus and potassium fertilizers, and applying them before flowering. If too much nitrogen and too little phosphorus and potassium are used, the plant will not be balanced in nutrients, resulting in the leaves not turning red in the autumn.

Poinsettia care for leaves having white flying insects

Poinsettia leaves having white small fly, we can use capsicum water and chemical agents to kill insects. If the number of white small flies is little, usable capsicum water kills insects. If the number of small white flying insects is much, we can use acetylcholine, pyridone and zinc cyanide emulsion insecticide, then we need to replace flowerpots and soil, the plant in a warm and ventilated position. The following are Poinsettia care for leaves having white flying insects.

When we care for Poinsettia, if the number of small white flies on the leaves of Poinsettia is small, the pepper can be soaked in water for about 25 minutes, and poured on the plants and leaves with the water after soaking, which can get rid of the white flies very quickly. White flies are white whitefly, more difficult to get rid of. If the number is less, the use of pepper water has a better effect.

When we care for Poinsettia, if white flying insects are more, chemical agents can be used to kill insects. Acetamiprid, pyrazine and zinc chloride emulsion can be used and sprayed evenly on the plants and leaves after being mixed with water. There are many white whitefly eggs on the back of the leaves, which should be carefully cleaned and sprayed several times to effectively remove the white whitefly.

Before applying the pesticide, the leaves that have been seriously damaged by the insects should be cleaned up and sprayed on the plants and leaves. If the plant is more serious with insect pests, after spraying insecticides, it is best to replace the soil and flower pots to the plant. When we care for Poinsettia, instead of using a single chemical when spraying insecticides, buy multiple agents and rotate them.

The white whitefly is active in spring and attacks plants in humid and enclosed environments, producing a large number of eggs on the underside of plant leaves. When we care for Poinsettia, plants should be placed in a warm and ventilated environment. Carbendazim can be used to spray plants and soil for about 15 days to carry out bacteriostatic sterilization and do a good job of pest prevention.
