What causes Phalaenopsis orchids to drop their flower buds?

Some growers have encountered Phalaenopsis orchids dropping their flower buds and really have no idea what is causing it. This article is an experienced grower's analysis of the reasons Phalaenopsis orchids drop their flower buds, and it is of great reference value for beginner growers. Bud drop in Phalaenopsis orchids is not necessarily caused by a single reason, and growers need to investigate carefully.

1. Failure to adapt to the environment: Generally, before Phalaenopsis orchids are shipped out, they are grown in a greenhouse or a cooled forcing room. Either way, humidity is added, and once they are moved into your home, it is inevitable that they will be somewhat unable to adapt;

2. Drastic temperature changes during transport: Some varieties that are less tolerant of transport will begin to show these symptoms;

3. The placement location is too warm: Generally speaking, if Phalaenopsis orchids are at a temperature<25度，养分会促进开花，但若温度较高则光合作用产生的糖份会往根茎叶跑，自然花卉会受影响;

4. If your leaves also look sickly and lifeless at the same time, it is very likely that the roots have rotted;

5. Variety issues. Generally, when selecting market orchids, besides good appearance and ease of cultivation, the most important factors are tolerance of transport and a long flowering period. Varieties that drop buds easily are usually not qualified to be market orchids.

　　3. Advice from a grower with 20 years of Phalaenopsis growing experience.

To grow Phalaenopsis orchids, you only need to master 1. watering; 2. lighting; and you are more or less ready (this is a point that the experts I know all agree on). As for fertilizer, its effect is not obviously positive or negative.

1. Fertilizer: Spray phosphorus fertilizer before the flower spike appears. From the appearance of the flower spike until the first flower bud is the size of a grain of rice, it is recommended to spray nitrogen-potassium fertilizer (nitrogen grows the flower stalk, potassium makes it thick and strong). Finally, spray phosphorus fertilizer to grow the flower buds. Once the first flower bud is close to blooming, stop spraying fertilizer completely.

2. To grow Phalaenopsis orchids, you must first solidly practice the skill of "watering" (giving the right amount of water at the right time).
