Keep orchids in mind a general rule is to blossom beautifully.

Summer is the season when orchids begin to sprout. At this time, because the weather is relatively hot, many flower friends choose not to fertilize orchids. In fact, this practice is not scientific. To fertilize orchids, in fact, all seasons, as long as remember a "general principle", flowering can be beautiful Tut-tut.

This "general principle" of orchid fertilization is the growth habit of "orchid like fertilizer but afraid of turbid". The words "acid" and "talk" must be kept firmly in mind when using fertilizer. That is, do not apply partial alkali fertilizer, do not need partial alkali water to dilute fertilizer. In order to test the acidity and alkalinity of fertilizer diluent, the pH value should be 5.5-6.0, and the retting organic fertilizer should be diluted 150-200 times. Sprinkle organic fertilizer and organic granular fertilizer, the amount should be less, not more.

The use of chemical fertilizers is generally not recommended because it is easy to cause fertilizer damage. It is recommended to use liquid organic fertilizer for orchids. The dilution concentration should be 500-1000 times. Once a week, the orchids can grow vigorously and bloom.

In addition, raise orchids, do not fertilize frequently. That is, the interval of fertilization is not too short, using root application, once every 15-20 days is suitable. If you want to apply thin fertilizer frequently, you can dilute the dilution concentration by one time (that is, the original dilution is 500x, now dilution 1000 times), then you can pour it once a week. Use a spray can with uniform effluent, and it is appropriate to spray once every 7 to 10 days.

So, some flower friends may ask why the interval is so long and the concentration is so light. The reason is that this "general principle" of fertilization: lan likes to be fat but afraid of turbid. Some flower friends often mistakenly think that more fertilizer and thick fertilizer will stain and rot the roots. You can always spray more fertilizer.

In fact, fertilizing orchids, just like people, eat three meals a day and want to eat small snacks, but isn't it "hungry" to fertilize the leaves once a week? Besides, foliar fertilizer is only a little bit, the dosage is less than soy sauce, it is tasteless at all, what's wrong with a little more?

In fact, fertilizing orchids, especially foliar fertilizer, is generally highly concentrated, which is like monosodium glutamate, which cannot be "eaten" if applied too much. In fact, these views have long deviated from the orchid's habit of "fattening but afraid of turbid". If the flower friends who raise orchids love to overcut, they often spray fertilizer and pour some casually when diluted, and the fertilizer almost blocks the leaf holes.

If the air humidity is low, the root system is less or the absorption function is low, and there is not enough water to dissolve the fertilizer on the leaf surface, it will hinder the photosynthesis and respiration of the leaf, which will lead to slight wilting, growth stagnation and early senescence. Therefore, it is appropriate to spray foliar fertilizer every 7 days, with orchid special liquid fertilizer, diluted 1000 times, do not increase at will, to avoid counterproductive results.
