All about Dendrobium Orchids

Dendrobium Orchids have gorgeous blooms and they are very popular house plants for this very reason. They have a three-stage life cycle. It consists of a blooming stage, a growing stage and a dormancy stage. They usually bloom from winter to spring and they grow from summer to autumn. Between autumn and winter, the plant is dormant. Provided you care for this plant properly, it can as much as double in size within the first year.

Light conditions

This type of Orchid is one of the more light-tolerant of the lot. It can handle direct sunlight in the morning but it does prefer afternoon shade.

Best temperatures

The ideal daytime temperature for this plant ranges between 20 and 29 °C. At night, they enjoy slightly cooler temperatures between 18 and 24 °C. When in bud, they prefer warmer climates because the colder temperatures cause the buds and flowers to fall. If the temperatures are notably cooler throughout the spring, the plant can bloom up to three times in a single year.

Watering schedule

Water is where it can be quite easy for anyone to go wrong no matter the type of plant. The best approach is to check the potting mix before you water. If it is damp, wait a day or two before you check again. When the potting mix is almost dry, you can water again.

Fertilizer for Dendrobium Orchids

Usually you only need to add fertiliser during the growing stage of their life cycle. You will find special Orchid fertiliser that is often the best choice. Different types of plants require different amounts of each nutrient. Orchid fertiliser is specifically made to suit these plants.

When in bloom

When your plant is in bloom, you need to water weekly but you do not need to add fertiliser. You can add a humidity tray to encourage growth and you can spritz the plant too.

During the growth phase

This is when your Dendrobium Orchid needs extra nourishment and it’s time to add fertiliser. Make sure that you follow the instructions carefully and watch your plant thrive.


When the plant is dormant, you will notice root development. At the end of this stage, you will see a stem sprouting from the Orchid. This is a sign that the plant needs water and fertiliser. If this stem does not appear, you can still encourage blooming by adding a high phosphorous fertiliser.

Remember to make sure that your Orchid has enough support. Just like vines, you will need to add some kind of spike or support and attach the plant to it very gently. You do not want to damage the plant in the process. With these tips in mind, your plant will bloom year after year and fill your home with amazing beauty.
