< b > what if orchids don't blossom < / b >

There are many reasons why orchids do not bloom. Orchids need to be investigated and analyzed. For a normal adult orchid, as long as it reaches more than two or three conjoined plants, it can blossom under normal circumstances (a small number of orchids can also blossom, and cold orchids with thick roots and fine leaves often have this phenomenon).

The main results are as follows: 1. the plant of orchid is still small and does not have reproductive genes. Some young seedlings that have not yet formed pseudobulbs can bloom only after two years of vegetative growth to form pseudobulbs, and then germinate new shoots two or three times, and the branches are three generations in the same house.

2. Scattered planting will destroy the transmission habit of reproductive genes of orchids from generation to generation, so orchids should be planted in clusters, less leaves per plant, less ash accumulation of organic matter and no active reproductive genes. Generally speaking, it is difficult to blossom without three generations of pseudo-bulbs in the same house.

3. Improper dry and wet, spring and summer and autumn are the vegetative growth periods of orchids (but need to avoid plum rain and torrential rain). If autumn is too thousand, it will make vegetative growth. Winter is its dormant period, which should be on the dry side. If it is too wet, it is easy to make the basin soil freeze and expand, squeeze the roots, affect the new shoots of the following spring and summer, and affect its normal reproductive growth.

4. The light is too little, and the accumulation of organic matter is limited, which can not supply the needs of reproductive growth. Although Lanhuo is a shady flower, it does not mean that it does not need time. It only avoids direct and long light. But need to diffuse, scattered light (semi-shade). Plants that tend to grow in the shade have dark green leaves, but they are more difficult and less flowering, while those growing in the south and mid-summer shade are slightly yellowish-green, but with more flowers, and are gaudy and fragrant.

Another situation is that orchids cannot blossom for their own special reasons, or a very small number of orchids do not like to blossom. This phenomenon has appeared in various orchid species, and I have also encountered: in 2004, a vegetarian Jian Lan, which came down the mountain, has been cultivated in this garden for six or seven years, and it has developed to more than a dozen pots. I have never seen flowers until now. This is probably the sterility of plants (orchids).
