How to make orchid flowers bigger?

First you could delay transplanting until they finish flowering. One might think, it would be better to transplant your orchids to a fresh soil mix at the time you purchased them. However, I don’t recommend doing that as it may cause the plants to drop the flowers well in advance. particularly when they are in the premature stage. Ideally you need to conduct repotting only when they drop their last bloom. 

The reason behind that is because only then they would start to grow actively. Further during this period, they would start to prepare their leaves, roots for the next blooming session too. When repotting ensure that you remove the dead roots while using a scalpel. However, before you use the scalpel make sure that you sterilize it. Next choose a pot which has ample draining. The selected pot should be slightly larger than the plant.  ideally it should be no bigger than one inch from the plant’s size. 

Next use a specialized potting medium and plant them. Do not grow them in regular soil as those conditions would not be optimal conditions for the plants. Next you could trim the dead spikes to make their blooms grow bigger. Once you snip off their dead spikes, it would allow them to regenerate when they are dormant. 

Once you remove them, it would further help them to recover from stress as well. Not only that but also, it would help them to conserve energy and develop much bigger flowers. Once you cut these off, it would encourage bigger blooms. Finally, when you reduce the ambient temperature slightly during night, it would also make them emerge with bigger blooms.

To do this, you could simply move them to a spot where there will be a drop in nighttime temperature. Ideally your preferred spot should be windowsill.

Do orchids stop growing?

Orchids can stop growing due to several reasons. If your orchid was growing all well and if you witness a sudden stop in the growth, it literally means something is wrong with the plants. For example, if you change the fertilizers it could result in the stop of the growth. It would be more like a sudden change of the diet for them, and they would respond to it by halting the growth. In addition to that if the orchids are running short of conserved energy that would also force them to stop growing any further. 

Moreover, if your orchids are running short of sufficient Nitrogen and Phosphorus  levels, that would also contribute to the halt in growth. So, if you use the wrong fertilizers even though you feed the orchids in the right way , it is very unlikely that you can gain the benefits of fertilizing.

Underwatering is one more reason as to why your orchids may halt their growth. So, literally if you had watered the plants well and all of a sudden stopped, it would badly affect the plants and stop growing them.  

Further, if you expose them to a drastic change in the growing environment it would also traumatize them and result in halt in growing. When I say changes in the growing conditions, if you expose them for sunlight for prolonged periods and if you end up using a  decomposed potting medium , those factors will contribute  for the halt in growing of the orchids.

How to care for large orchids?

To briefly explain on the basic care treatments that orchids need, they would prefer to have a potting medium which has excellent drainage. Further it is important that they have at least six hours of indirect sunlight on a daily basis. Next , they need to have moistened soil and not waterlogged and soggy soil. In addition to that I recommend feeding the plants once a month which is diluted to a quarter strength. Last but not least you need to grow them in a humid area and prune them when it is required.
