  • Bark – On the other hand, bark drains quickly and doesn’t hold too much water. Thus, they are the ideal choice for the species of Cattleya and Phalaenopsis.

The best position for a standing shade is on a north-south axis so that the sun travels across the entire length as it moves from east to west. If your greenhouse is leaning, let it have exposure in the east or south.

Besides, you should avoid nearby shade trees or shadows from nearby homes or buildings. To cut down on intense light is easy, however, it is hard to provide light when the greenhouse is shaded beyond your control. 

When planning for the construction of your greenhouse, there are many factors to be considered. Most require professional advice.

Apart from the site,  the window direction influences the orchid light exposure. It’s crucial to know the amount of sun exposure to the orchids because they require different levels of light.  Here are some directions for the window to face.


The window faces the sun exposure. This makes it a good direction for orchids that require a lot of  sunlight


This window direction offers your orchids more hours of light exposure to morning sunlight. This is good for sun exposure to orchids in summer, spring and fall. 


The window direction offers orchids more afternoon light to orchids. Your orchids get hotter environments. Take care the direction can lead to too much light, leading to the death of your orchids.


The light is not enough for orchids to grow healthy. This is good for ferns that require less light.

Your Shade Cloth Color

Whether orchids are placed in a greenhouse or shade house installing shade cloth is important.  The shade cloth allows your orchids to grow taller  and have bigger leaves

Different shade cloth colors provide different benefits to your orchids. Here are some of the benefits:

If your area has higher temperatures during summer, choose a shade cloth of 70 to 90%. But if you are from areas with the winter season, use minimal shade.

Types of Orchids

The light required by orchids varies with the types. Take, for example, Bulbophyllum  Paphiopedilums and Phalaenopsis. They need 30 – 60% of light for  4 – 6 hours every day. Therefore, to achieve this light intensity requirement for these orchids, you need 75-80% shade cloth.

The light-loving orchids such as Oncidiums, Dendrobium, and Cattleya need 50% or less shade cloth depending on their location.


Orchids produce beautiful blooms but require pruning once the flowers fall off. Pruning improves your orchid health and flowering. Below are some of the orchid parts to prune:

Prune The Roots

You need to trim the roots that are not benefiting your orchid. The dead roots are brown and appear to wither. These are the ones you should cut off. If the roots are grey and are strong, then they are healthy and you should not cut them off.

Pruning Diseased Orchids

Prune the diseased part of your orchid. The parts appear unhealthy, diseased, or broken. You need to cut these parts out to avoid the diseases from spreading. Besides, these damaged parts tend to attract pests. 

Prune Overgrown Orchids

You need to look for the big and heavy parts. This is to ensure your orchids grow healthier. Ensure you only cut overgrown orchids when they are healthy.

Leaf Pruning

This is to keep your orchid in the right condition. If you find the leaves have become black, cut them off. The darkening of the leaves might be caused by bacteria or fungi. And if the leaves are left on your orchid, the bacteria spreads. 


Proper care and a healthy environment are essential for the growing orchids. To grow them in your green or shade houses better, provide them with enough water and sunlight to make them healthy.
