The keys to basic maintenance for orchids are sunlight and water. However, for orchid plants to truly perform well and bloom vigorously, suitable orchid fertilizers are essential.
What Kind Of Orchid Fertilizer Are Essential
Nitrogen is essential for increased chlorophyll, which promotes proper leaf and stem development.
Note, You’d better choose Ammoniacal Nitrogen or Nitrate Nitrogen, Unlike urea (can’t be well absorbed by orchids), recent studies have shown that these compounds are more suitable for orchids growth. And nitrogen content should not be excessive, otherwise, it will affect the flowering.
Potassium helps to produce strong leaf tissue. And is mainly responsible for the control of flower and fruit development. Phosphorus is excellent for healthy roots and aids in orchid blooming.
The Best NPK ratio is 20-20-20 or 10-10-10.
Also, Calcium and magnesium are micronutrients that your orchid needs. Orchids use calcium to build cell walls and other structures while magnesium is used to produce chlorophyll for metabolic processes.
Organic Bio Orchid Fertilizer
Organic bio orchid fertilizer has the role of root disease control, soil conditioner, resistance ability enhancer.
It contains beneficial microorganisms contains trichoderma ,bacillus subtilis that can produce a variety of bacteriostatic, insecticidal substances, and antagonize and compete against many pathogenic bacteria such as Phytophthora root rot, Pythіum root rot, and Brown spot. It can help growers reduce the use of pesticides.
Compared with common NPK fertilizers, in addition to NPK elements, organic orchid fertilizers also contain natural plant growth regulators and various trace elements. Increase root system development and promote flowering.
As orchid is a delicate plant, too much pesticide residue will cause negative damage to it. So environment-friendly fertilizer is more suitable.
Last but not least, when you fertilize orchids, there are a few points that need special attention:
Fertilizer should be used at half-strength, making it with an equal amount of water before applying it to your orchid. To avoid burning the orchid’s leaves, do not pour fertilizer directly over the plant. Do not water your orchid on the weeks you fertilize it.
