How to Care for Poinsettias: Weather

When planting outdoors, choose a site with good lighting, not exposed to air currents or sudden temperature changes. It is not recommended to place it in gardens when frequent frosts and temperatures below zero are registered in the area.

They should receive as much light as possible when they are in bloom. The leaves fall in low light.

The temperature should be between 59-62 °F (15-17 ºC) at night and 68-77 °F (20-25 ºC) during the day. It should not fall below 50 °F (10 ºC). If the leaves fall without anything happening, perhaps it is because of the cold.

How to Care for Poinsettias: Soil

The most suitable soil for the development of this plant is a well-drained substrate enriched with compost.

How Often Do you Water Poinsettias

As for the watering, at the beginning it should be abundant but always when the soil has completely absorbed the water of the last application, to avoid the excess of humidity. While it is in flower, it is convenient to water a couple of times a week without letting it dry out. When the flower has been lost you can reduce the watering to once a week.

During watering, care should be taken that the water drops do not reach the colorful bracts surrounding the small yellow flowers, to prevent the appearance of unsightly spots or loss of pigmentation.

When growing indoors, it is recommended not to water the soil directly, but to place the pot on a plate with water for about 15 minutes, repeating the task twice a week, but taking care that between watering the substrate is partially dry.

The Keys to Making the Bracts Bloom Again and Take on Color

Several things must be taken into account for the plant to achieve good flowering and its striking red leaves.

This is a plant that needs to go into dormancy after its flowering season, as is the case with many others. Place the plant in a cool place away from heat sources. In this way, the poinsettia will enter those months of “rest it needs”.

When the leaves have fallen and it loses its bracts, cut the branches leaving stems of between 2” – 4” (5-10 cm), with disinfected and very sharp pruning shears, in diagonal cuts. The cut stems can be used as pointed cuttings, to multiply the plant.

In spring, with the arrival of heat, it is necessary to transplant it. Use universal substrate mixed with earthworm humus and sand, making sure that the mixture will offer very good drainage and a high contribution of nutrients.

For it to bloom again, 12 hours of absolute darkness are required. For this, you must cover during the nights with black plastic and uncover in the morning. Also, avoid bringing it close to sources of heat.

If you follow all these steps, it is very probable that when the holidays come, your plant will show some bracts of a very bright red, and you can use it to decorate or as a centerpiece. If it still resists, you can use special fertilizers for the plant, which favor the coloration.
