What to Do If Poinsettia Won't Bloom? Care Methods Differ Across the Four Seasons

In the world of flowers, the poinsettia enjoys great fame. It blooms around Christmas, New Year's Day and the Spring Festival, and is a very festive flower with flame-red color. However, during cultivation, improper care may prevent the poinsettia from blooming, so what should you do if it won't bloom? The key is still care. Below are the poinsettia's four-season care methods carefully selected by the editor, very comprehensive, so flower lovers, you must take a look~

I. What to Do If Poinsettia Won't Bloom

Earlier, we already introduced the effects and uses of the poinsettia, and know that it is not only highly ornamental but also has good medicinal value. But all of this has one major prerequisite: the poinsettia must bloom. However, for certain reasons, the poinsettia may not bloom, so what should you do if it won't bloom? For this, the editor has sorted out several causes; just address them accordingly. The specific causes are as follows:

1. Long-term lack of light

A poinsettia that won't bloom may be suffering from long-term lack of light. With insufficient light, the poinsettia not only grows poorly but is also prone to disease, so the red bracts are not seen.

Solution: Quickly move your poinsettia to a sunny spot, and its red bracts will, I believe, soon appear.

2. Insufficient fertilization

During the growing period, the poinsettia needs a large amount of nutrients. If it lacks fertilizer at this time, it is fatal to its growth. A poinsettia lacking fertilizer is often short and spindly; blooming would be a miracle.

Solution: Quickly apply some special plant nutrient fertilizer for it; this is very good nutrition for it to sprout and grow red bracts. I believe that after a period of careful care, your poinsettia will bloom.

3. The flowering period has not yet arrived

The poinsettia won't bloom. Besides the above two main factors, there may be another reason: the flowering period has not yet arrived. The poinsettia's flowering period lasts from December to February of the following year. If its flowering period has not yet arrived, that is, it is still in the growing period, green leaves may be constantly sprouting, so the red bracts that flower lovers see are naturally fewer.

II. The Poinsettia's Four-Season Care Methods

To make the poinsettia grow well and its flowers bloom beautifully, to put it plainly, it requires our careful care. However, in the poinsettia's cultivation methods and precautions, we have already learned that the poinsettia has many requirements when grown indoors, and they differ across the four seasons. For this reason, to make things convenient for flower lovers, the editor has sorted out the poinsettia's four-season care methods; you might as well take a look.

1. Spring care of the poinsettia

Repotting: April to May in spring is the best time for repotting. When repotting, use fertile soil with good drainage. The quality of the soil directly affects the poinsettia's growth. When changing the soil, replace 1/3 of the soil, so as to avoid the plant not adapting to a large-scale soil change.

Pruning: After repotting, ensure the plant has sufficient water and light to promote new sprouting of its branches. The newly grown semi-lignified branches can be cut off for cuttings. At the same time, the plant shape can be properly pruned so that the old branches are evenly distributed. If you do not prune the branches, you should pinch out the growing tips 2-3 times to ensure a full plant shape.

Watering: Water when dry, stop when wet. Spring is the poinsettia's peak growing season, so sufficient sunlight must be ensured, and watering must not be neglected either. Ensure the potting soil is dry-wet alternating. If watered too much, the potting soil stays moist for a long time, root growth is poor, and root rot easily occurs. But if the potting soil stays on the dry side for a long time, the roots easily shrivel, causing the plant to lack water. So water when dry and stop when wet.

2. Summer care of the poinsettia

Light: Avoid high temperatures and scorching sun. The poinsettia is not tolerant of high temperatures and blazing sun. In summer, the temperature should not exceed 28°C, otherwise growth will be poor. The plant should be placed in a semi-shaded environment to ensure sufficient water supply. When the temperature is high, spray water around it frequently and strengthen ventilation to lower the temperature. If the temperature is above 28°C, the poinsettia's growth stalls, so fertilization should be stopped, and resumed after the temperature drops.

Watering and fertilizing: In summer, despite the high temperature and stuffiness, under normal conditions the poinsettia still grows normally, so water must be replenished in time, watering once each in the morning and evening, and avoiding watering under the scorching sun. Apply decomposed liquid fertilizer once every 20 days, preferably in the evening, and let it get sunlight the next morning.

3. Autumn care of the poinsettia

Light: In autumn, as the temperature gradually turns cooler, gradually increase the morning and evening light and ensure a sufficient supply of water and fertilizer. If the plant shape has already taken form, short-day treatment can be carried out to force flowering.

Temperature: In late autumn, the temperature drops, so attention must be paid to controlling the temperature, and the plant should be moved indoors in time, with the indoor temperature kept at around 20°C.

4. Winter care of the poinsettia

Temperature: The poinsettia is not cold-tolerant, and when it blooms in early winter it should be kept at 15°C, with sufficient light and a sufficient supply of water and fertilizer. Insufficient temperature affects flowering, and at the same time the leaves will turn yellow and drop, forming bare stems and affecting the ornamental value. When winter comes, all the previous efforts are rewarded. At flowering, appropriately lower the temperature; at 5-10°C, the viewing period can reach 2 months.
