Why is my orchid not blooming?
 
        Firstly, it is important to make sure that your plant is in the right flowering season. Most orchids bloom only once a year. Sadly, some bloom for less than two weeks during the year. 
  Second, we need to understand that flowering is the culmination of a cycle. The orchid spends a whole year getting ready, getting stronger, to then show its flower in the expectation of generating seeds. This means that your plant needs to be in good growing and nourishing conditions to flower. Even so, orchids can try to flower weakly as a "last gasp", in which case it is ideal that you cut the buds even before they open so as not to lose the plant.

But, what if your orchid looks healthy, growing well and doesn't flower? 
 
1- Does the orchid you cultivate have specific needs? 
          Some orchids, mainly those that live outside Brazil, often have special needs. Some of them wait for a sign from nature to flower. For example, the popular Cymbidium need a cool period to flower. They wait  for this sign, since in nature they flower after the period of snow formation. Try covering the plant with ice in May! in July it will have a beautiful flowering (temperatures night temperatures of 10 to 15 °C in the months before flowering can also work well). The Coelogyne also need the cold to know when to bloom.   Dendrobium, on the other hand, needs a dry period from May to July to flower, in addition to short days, from 9 to 10 hours, with cold temperatures, between 10 to 13 °C, for 3 months . If you don't have this period of drought, they can at most give a weak flowering, but normally they will give many seedlings.  In the same way, short days with lower temperatures are a prerequisite for the flowering of Miltoniopsis and Zygopetalum.   The champions of floriculture, as Phalaenopsis, require nocturnal temperatures of 2 °C of 2 °C and daytime for flowering without a special duration for the day.  Thus, we return to the point that the fundamental thing is to know exactly the needs of your plant.
 
2 - Does it have a nutritional deficiency? 
      One of the nutritional deficiencies that result in the absence of flowering is that of the element Phosphorus (P). If you are giving a quality balanced fertilizer, this is probably not the cause of the lack of flowering. What you can try is to increase the concentration of phosphorus in the fertilizer from four months before the normal flowering period. This in itself already increases the quantity and quality of the flowers. Read all the details in the item "Fertilization" in the menu "Cultivation"
 
3 - Is the light missing? 
         Essa é sem dúvida a maior of the reasons why orchids do not bloom. It happens that many times we buy orchids in bloom, put them inside the house to contemplate the flowers and after finishing the flowering, we still leave it inside the house waiting for new flowers to come. If you don't have an orchid house, you need to read the topic "ORCHIDS IN THE APARTMENT"  in the "cultivation" menu. 
 
4 - Is there any pest attacking your orchid? 
      Especially indoor plants are often attacked by aphids and mealybugs. These pests are suckers, which means that they will suck the nutrients and the orchid ends up not having the strength to flower.
