Growing Poinsettia Plants Outside

Poinsettias grow best in USDA hardiness zones from 10 to 12. The temperatures outside shouldn’t be less than 45 degrees F. Poinsettias can grow outside if you take care of them properly. The location that you will plant the poinsettias is very important.

They need to be planted in a sunny area and they have to be protected from the winds because they are sensitive plants. In order to grow, they need a well-draining soil that will be slightly acidic too. The soil must drain well when you water it, you don’t want the roots to rot.

When the time comes for you to plant it in the ground you should create a hole. The hole should be wide enough. It should be about the size of the root ball that the plant has. Add mulch to the area around it up to 3 inches in this way, the soil will be moist enough.

Water and fertilize the poinsettia. Water the base and not at the leaves. Depending on the soil that you have you might need to fertilize it either one time each month or more.

Growing Poinsettia Plants Indoors

Growing your poinsettia plant indoors would be ideal, especially if you leave in an area where the climate is cold. You should also place it where it will have plenty of sunlight. The right temperature for poinsettias to grow indoors would be 65 degrees.

What poinsettia also needs is water. You don’t need to overdo it with watering. You only need to water the plant when you feel that the soil is dry when you touch it. What you should do is to add slowly the water.

You should do that because water needs to be absorbed before you add some more. When you start to notice that the saturation slows down and the water doesn’t drain then you should stop watering it.

Fertilization is also important when you grow your poinsettia indoors. Poinsettia is a plant that needs to be often fertilized. You can use a rounded liquid fertilizer that will help your plant. An analogy that you can use is 12-12-12 or even 20-20-20 and you will have a great result.

Fertilization should take place once per month. Have in mind though that when fall comes you will have to stop fertilization. In this way, you will help the plant produce flowers and thrive.

You should also provide long nights without any sunlight because you want the color of the leaves to change and from green and to take this lovely red color that we all expect it to have, especially during Christmas time. You should do that from 9 to 10 weeks until you see the flower bracts form on Poinsettia.

Keep the plant in complete darkness 14 to 16 hours per day and during the morning place it to a sunny window. Once the Christmas period is over and you notice that the small yellow flower wilt you should prune it. Prune it at least 10 inches tall. Also, stop watering it until spring comes. Let the soil dry before you start watering again.

How to Grow Poinsettias in a Greenhouse

The temperature of your greenhouse should be from 65 to 70 degrees F. Additionally, when you will place them inside your greenhouse don’t place them close to the doors, keep them far away. You don’t want the temperature to change. Make sure that there will be plenty of sunlight for at least 6 to 8 hours per day.

You should water them every 4 days only when you will realize that the soil seems dry. Fertilize them once per month and use a liquid fertilizer. Once they will lose their leaves maintain the temperatures at 60 degrees and reduce the fertilizer and the watering process. Do it one time each month.
