Non-Hybrid versus Hybrid Species
Before I share various useful tips for aiding your process of cultivating orchids, you should know that as far as the different species of orchids are concerned, the hybrid varieties are often much more resistant as compared to the non-hybrid species, for various reasons.
Another fascinating aspect of cultivating orchids is their ability to adapt easily to various climatic zones. This means that if you have procured an orchid from a particularly warm or humid climatic zone, you can still easily sow the seeds and grow the same orchid, in say a place where the weather is comparatively colder and dryer.
Extent of Shading
The extent to which an orchid needs to be shaded is very important, and forms the core of any orchid species cultivation. If too much direct sunlight is provided to this seeded flowering plant at any stage, it will succumb to drying and withering away. On the contrary, if the sunlight provided is insufficient, it will lead to stunted and slow growth. The ideal balance to strike here between shade and sunlight is about 60:40. You can probably start with 70:30 and slowly increase the degree of sunlight exposure as the plant grows and becomes more resistant.
P.S- If you happen to see yellowish-brown sun-burnt leaves and petals in your plant, it is a clear indication of excessive sunlight exposure. Similarly, when you look at your plant having abnormally dark green foliage but no flowers, please understand that this is a direct effect of insufficient sunlight exposure. So there needs to be a well-matched balance between the both.
In case the soil that you have grown your orchid in, happens to be naturally fertile, you really need to restrict the use of artificial fertilizers till the time the plant has grown and flowers are in bloom. However, if the initial soil quality is poor, you will definitely need to provide external nutrition from time to time, else you will find the leaves getting wilted, yellow and falling off at an early stage. Also, as far as watering is concerned, the same needs to be coordinated vis-à-vis the extent of sun exposure and shade provision. If you provide insufficient water despite good amount of sun exposure, you will find the plant drying up, whereas giving too much water has its own signs, especially when the plant has been kept in the shade cycle. All said and done, there needs to be a balance that needs to be followed to the core.
P.S- While I have outlined a number of handy tips for growing and maintaining orchids above, please note that there are a lot of differences that emerge in the cultivation process of different species. In fact, the care regime of no two orchid species can be termed as alike, and therefore, the above tips just form a general outline. You can grasp further information only out of experience, as you dive into exercise with your own experiences.
