What kind of fertilizer is good for orchids? Saving money and safety is the first place. These are all good choices.

Orchids like fertilizer. When we look for wild orchids in the mountains, we know that those wild orchids with large clumps and dark green leaves mostly grow in fertile humus soil, and the roots of wild orchids grow horizontally parallel to the ground. this is to absorb as much fertility as possible. So recently, when Lan you discussed orchids with the farmer, he said that orchids should be more suitable for shallow pots rather than deep pots. Of course, this is another topic.

The root of a wild orchid with 5 seedlings can expand to a circular area of 60 cm in diameter. The fertility it needs can only be obtained in more humus.

Orchid fertilization is generally organic fertilizer first, first of all, the culture medium mixed with humus soil, which can solve the fertility of the early pot. It is a bit troublesome for the farmer to choose humus soil. First, not on the hillside; second, not on the hillside. The humus soil chosen by the farmer is in the trench between two sloping slopes, where there is more organic matter washed down by Rain Water on both sides of the hillside for a long time.

In the later stage, rapeseed cake and tea withered cake can be used to apply fertilizer. You can also mix the rotten cake fertilizer into the plant material, and you must rot thoroughly. The specific method is to put the needed cake fertilizer in the water tank, seal the cylinder mouth with plastic film for three to five months, and pour the liquid from the upper layer. Then the residue of the lower layer is mixed into the plant material. The plant made of this kind of cake fertilizer has a long effective period and mild fertility release.

Combined with foliar fertilizer spraying, orchid foliar absorption capacity is very strong, foliar fertilizer nitrogen, phosphorus and potassium balanced ratio, spraying leaves on both sides, in fact, the reverse side of the leaf absorption is stronger. Generally used is urea plus potassium dihydrogen phosphate, once every half a month, high and low temperature periods to stop spraying.

As for chemical fertilizer root application (all kinds of chemical fertilizers commonly used in agriculture) is generally not recommended, but there is a kind of orchid-specific slow-release fertilizer in the market, the specific effect, good farmers have not personally tried, do not dare to discuss.
