True, there is a correct way, and an incorrect way to water your orchids.  However, if you have a greenhouse full of over 100 orchids, this is an impossible task at best. This is more geared to the orchid fan who has a small number of orchids in their collection and hand-watering each orchid is somewhat simple.

 

This discussion will focus on the rules and methods for watering.  Following these guidelines will help your orchid maintain a healthy condition all year long and most importantly during the bloom season.

Feeding your Orchid

One would never consider the actual "pot" as having any affect on an orchid's growth, but you could never be more wrong.  Clay versus plastic?  If plastic, black, green, or transparent?  Drainage holes on the bottom?  What about ventilation?  All of these factors, individually or combined have an affect on the orchid.  The right choice will result in a thriving orchid.  The wrong choice typically ends up in a slow death for an orchid.

 

Let's not forget, size means everything.  Too big, or too small?  If there is such a thing as "too small".  Orchids favor the goldie-locks zone - where it has to be just right.

 

Knowing your orchid will make all of these factors easy to master resulting in the best of blooms.

Depending on the type of orchid, potting medium plays a big role in the root system thriving.  Small to large chunks of bark, gravel, cork, tree fern (shredded needles to chunks) and even old shoes can be used to hold an orchid in place.  This presentation will examine several common orchid root systems, and determine the preferred orchid potting medium to be used. This will also include bare-root mounting of orchids.

Individually and combined with each other, temperature and humidity (of the orchid's surroundings) can have a negative effect if extremes are exposed.  As mentioned in the section related to photosynthesis, both temperature and humidity can have an affect on the photosynthesis process, perhaps causing the orchid to be in a state of stress.  With regards to both temperature and humidity, steps can be taken to maintain an optimum level of both, making the orchid happy.

Just as we can be sunburned from being exposed to too much sunlight, be it intensity or length of time exposed, so can the leaves of orchids.   Preventing "burn" is optimal, however there are a number of simple steps that can be enacted to prevent  this burn.  If your leaves do suffer burn, react accordingly, but there is no need to remove the burned leaf.  The orchid will do that eventually.  This section will detail levels of light optimum for a variety of orchids as well as a simple test to determine if your orchid is getting too much or too little light for optimum photosynthesis to take place.

Photosynthesis is the process by which plants, some bacteria and some protistans use the energy from sunlight to produce glucose from carbon dioxide and water. This glucose can be converted into pyruvate which releases adenosine triphosphate (ATP) by cellular respiration. Oxygen is also formed.  Don't let this definition confuse you, the goal of this presentation is to explain the photosynthetic process in simple terms.  Once understood, you will appreciate how important light is to green-leafed plants, including the orchid.

Bulbs and psuedobulbs are storage areas for water developed by orchids to survive short term droughts.  They are essential to the orchid for the purpose of surviving.

 

Cymbidium bulbs and psuedobulbs from other types of orchids (Cattleyas) can be used to generate new orchids.
