Choose the right type of Cymbidium

While a greenhouse can be customized for any type of Cymbidium, it is easiest to grow Cymbidiums that are suitable for the climate. As a rule of thumb, there are three types of Cymbidiums by temperature tolerance:

1) Cool growing:

These hybrids were created using species that grow naturally in cool climate of mountains such as Cymbidium hookerianum and insigne. These hybrids typically have large flowers and grow tall.

2) Warm growing:

These hybrids were created by cross-breeding species that grow in cool climates and tropical climates, such as Cymbidium ensifolium and Cymbidium hookerianum. They typically have medium size to small flowers and are medium in height.

3) Heat tolerant:

These hybrids were created using species that grow naturally in tropical areas such as Cymbidiums ensifolium and canaliculatum. They are smaller in size and have smaller flowers typically.

 

Now if the plant is suitable to your location then it will flower without many adjustments needed. Warm and heat tolerant Cymbidiums require little care and also flower many times a year. But when it comes to presentation and beauty, cool growing Cymbidiums are a sight to behold.

Flowering cool growing Cymbidiums in warmer climates

If your Cymbidium is not flowering, then you may be growing a cool growing Cymbidium in warmer climates such as Bangalore, Delhi or Kolkata.  The following adjustments need to be made to successfully flower cool growing Cymbidiums in warmer locations in India:

1) Summer temperatures of maximum 35 degrees Celsius:

In places like Bangalore or Delhi, summer temperatures sometimes rise to 44 degrees Celsius. This stresses the Cymbidiums and disturbs the flowering process in winter because if the plant fails to grow and accumulate nutrients in the summer, it will not flower. To keep the temperatures low:

  • the plant can be moved to a sunny window indoors with comfortable room temperatures.
  • If growing in a greenhouse, temperature can be reduced by using a shade net to protect from direct sunlight. Regular misting and wetting the floor of the greenhouse will also help reduce the temperature. If this is not enough, a greenhouse fan can be used as it cools the temperature as well as prevents disease and pests.

2) Winter temperature dropping to 10-15 degrees Celsius:

Now that you have successfully grown the plant in the summer heat, the plants have grown and are looking luscious and fuller with new vegetative growth, it is time to flower. Cymbidiums require low nightime temperature of at least 10-15 degrees to start the flowering process.

  • If your plants are indoors, please place them outside but do protect from heavy rainfall in tropical areas. Temperatures normally drop to 10-15 degrees even in high temperature areas like Bangalore and Delhi.
  • If you plants are in greenhouses then no adjustments need to be made.

 

Nutrient requirements for flowering

Growth phase (April to September)

A 20-20-20 NPK fertiliser along with Calcium and Magnesium can be applied at full strength once a month. The dose is typically written in the fertiliser package. During this time the plant is focused on growing in size and storing nutrients for the winter flowering. The better the plant grows during this period, the better the quality and number of flowers in winter. 

Flowering phase (October to March)

A 10-40-30 NPL fertiliser along with Calcium and Magnesium can be applied at half strength once a month. In the cooler weather of winter, the plant is focused on producing flowers and stops growing in size. Giving the plant more fertiliser in this period is harmful as it may continue growing and skip its flowering phase. This is the main reason to reduce the fertilisation at half strength.
