Do You Water Poinsettias When They Are In The Dark?

Most people are familiar with the poinsettia plant. It is a popular Christmas decoration, and many people wonder if it needs to be watered while it is in the dark. The answer to this question is a little tricky. In this blog post, we will discuss if you should water poinsettias when they are not exposed to light and provide some tips on how to do this properly!

Do You Water Poinsettias When They Are In The Dark?

You should make sure your poinsettias are watered regularly but you do not want to interrupt their dark zero light exposure to water them because you risk exposing light during their 16-hour no light period in order to induce photoperiodism so the leaves turn red.

If you are growing poinsettias for the holidays, you should make sure to keep them in a dark room or closet with a 5-gallon bucket on top to prevent any light exposure from early evening until morning. This means no lights on at all during this time period, not even from a nightlight.

The red color of the poinsettia plant is not from its flowers, but from modified leaves called bracts. The flowers are small and yellow and grow in the center of the plant. Poinsettias come in many colors including red, white, pink, salmon, orange, and marbled.

The plant was once used as a decoration for altars during Christmas in Mexico. Legend has it that a young girl named Pepita was too poor to buy a gift for the baby Jesus and was instead going to leave him some weeds from the roadside. An angel appeared to her and told her that the weeds would turn into beautiful red flowers when she placed them at the altar. And so, the poinsettia became known as the “Flower of the Holy Night.”

Are There Any Other Tips Or Tricks That You Should Know About Caring For Poinsettias Plants During The Winter Months?

Here are a few more tips to help your poinsettias plants thrive during the winter months:

  • Keep them away from drafts, both hot and cold. This means avoiding placing them near windows, doors, or vents.
  • Humidity is important for poinsettias, so misting the leaves occasionally can be beneficial.
  • Make sure to fertilize your plants every few weeks with a balanced fertilizer.

With just a little bit of extra care, you can keep your poinsettias healthy and beautiful all winter long!

How Long Do You Leave A Poinsettia In The Dark?

It is best to leave a poinsettia in the dark for about 13-15 hours each night. This can be done by placing the plant in a closet or covered bucket overnight. If you cannot do this, you can place a newspaper over the plant each evening. Be sure to remove the covering in the morning so that the plant can get sunlight during the day.

Should I Put My Poinsettia In The Dark?

To get your poinsettia to bloom indoors for Christmas, you need to give it a long period of uninterrupted darkness each day. This “short-day treatment” tricks the plant into thinking winter is coming, and that it needs to start blooming.

You can buy poinsettias starting in mid-October, but don’t put them in the dark just yet. The plants need to adjust to their new homes first. Put them in a sunny spot and water them when the soil feels dry.

After a week or so, you can start the short-day treatment. Choose a place for your plant where it will be undisturbed in the dark for 14 hours each day, starting around Thanksgiving. A closet or covered porch works well. Put the plant in complete darkness at night and take it out during the day so it gets at least six hours of sunlight. Water when the soil feels dry.

How Often Do I Water A Poinsettia?

You should water your poinsettia when the soil is dry to the touch. Be careful not to over-water, as this can cause the leaves to drop. Poinsettias like humid conditions, so you may want to mist them occasionally with water. If the leaves start to yellow or drop, it’s a sign that your plant is getting too much water.

When it comes to watering, the best way to know is by sticking your finger in the soil. If it feels dry several inches below the surface, it’s time to water. If it still feels moist, wait a few more days.

Over-watering is the most common reason why poinsettias fail to thrive, so err on the side of underwatering. Your plant will tell you what it needs – just be sure to pay attention!

Do Poinsettias Like Light Or Dark?

Poinsettias are native to Mexico and they thrive in bright, sunny conditions. In their natural habitat, they can grow to be up to 12 feet tall! So when you bring them into your home, it’s important to try to replicate their ideal conditions as much as possible.

That means giving them plenty of bright light – at least six hours a day. If you can’t provide that much natural light, supplement with grow lights. And when it comes to watering, be sure to keep the soil moist but not soggy. Allow the top inch of soil to dry out before watering again.

Why Do Poinsettias Need Darkness

To understand why poinsettias need darkness, you first have to understand how they bloom. Flower formation is triggered by periods of darkness, which is why poinsettias are often called “short-day” plants. For a poinsettia to bloom, it needs at least 14 hours of complete darkness each day for six to eight weeks before the blooming season. This period of darkness is called “photoperiodism.”
