Why Orchid Flower Bud Loss?

Seeing a small protrusion appeared from the body of our orchids we may have often experienced. But it would be very happy if the bulge had grown into a small bunches of flowers with petals that lined the candidate along the bunches of flowers. After day after day passed by, prospective bud growing and .... 1-2 fruits candidate suddenly florets yellow and fall off ... .!!?? although some other candidates successfully grown bud and bloom, but inwardly there is a sense of curiosity, why it happened ....
There are many factors that could cause the collapse of the candidate before the flowers bloom. Here I extract from my friends on the discussion mailing list about the loss of orchid flower orchid:

    
* The first flower that appears from the results of orchid tissue culture in general, losing some potential interest, but it sometimes is only a short length of clusters and bring a little bud. This is because new plants enter the generative phase the first time in their life cycle, so that metabolic hormones as well as accumulation of ATP (energy) is still not perfect.
    
* Lack of light can cause hair loss. When the light is too low then the rate of photosynthesis is also low, so that food reserves are acquired only a little. When stimulated fertilizing plants with formulations for flowering, the plant physiological stimulated to enter the stage where the generative phase is more dominant. Consequently with the existing food reserves, the orchid remains determined to bring flowers. Finally, after the bunches are formed, usually of short bunches of flowers, and lots of falling interest candidate. This happens because the flowers candidates receive less food and energy supplies. Candidate interest is also a living tissue that requires energy and cell material.
    
* Drought due to high temperature is also one of the reasons why candidates fall flowers. Why? because at high temperatures the evaporation of water was too high. Reserve the water (moisture) in minimal media will quickly disappear due to evaporation. Evaporation does not only happen in the media (evaporation) but also occur on the surface of the orchid plant itself (transpiration). When the water evaporation takes place continuously, the plant will lose a lot of water in his cell. The organ was first exposed to the ill effects of declining water levels in the cell is young tissue (meristem) as candidates for flower bud, so that the prospective bud cells will shrink and the network looks wrinkled and eventually fall.
    
* Sudden temperature changes. A sudden drastic temperature changes can cause sudden physiological changes such as decreased enzymatic activity in the plant body. Enzyme activity is strongly influenced by temperature. The decrease of this enzymatic activity will lead to the effect of "stress" on orchid plants so that the various symptoms such as leaf yellowing and loss, etc. of candidates fall flowers. Level optimum temperature for enzyme activity varies greatly depending on the species. In addition, for the highland orchids have a candidate in a state of bud, then suddenly brought to the lowlands, the evaporation of water in the body of the plant will dramatically increase, so that the sensitive organs of plants (potential bud, root tips, etc.) will shrink and wither. Be careful to make orchids that have a potential bud and taken away and the long journey by car or air-space ac hot and stuffy, it is feared when exiting the car, the plant will be "shocked" by sudden temperature changes.
    
* The concentration of foliar fertilizer that is too thick. The concentration of fertilizer is too dense than a negative impact on other parts of plants, florets bungapun candidate is also very sensitive to damage. If liquid manure is the leaves that are too concentrated on prospective flowers then, are concentrated liquid will easily penetrate the cell wall because of the candidate flowers are a young network is still thin cell walls. After penetrating dindingsel then concentrated liquid will cause uncontrolled osmosis, so that the cell fluid would come out of the cell and plasmolysis occurs. Cell membrane will be wrinkled and damaged so that eventually the cell will die. From the exterior, will occur in the future drying flowers and then fall out.
    
* Invasion by flies (fly X, still in search of R & D team web.anggrek.org) most likely a kind of imago adult insects like fruit flies or butterflies that lay their eggs into the flower so the larvae will eat the bud, or the flies X had to suck fluid cells from the prospective bud.
    
* Lice attack elephants. Elephant louse has a habit of "taste-taste" network network she suction fluid young to his cell. In addition, adult fleas elephants also perform the same ritual to determine the exact position for the baby dear. After gaining the right position he would drill a passage to lay their eggs. Sections of young flowers is one of the favorite part of this infestation. Pas interview, said he still feels "sweet".
    
* Attack the disease. Attack the disease is generally a secondary effect due to environmental factors that support. For example, a too high humidity, air circulation is not smooth, the slits on the wet bud candidate (for a long time). All of these things would excite the disease to penetrate into the young tissues of the candidate flowers which incidentally is a young network that is still "soft" and sensitive to physiological disorders.
    
* Effect of chemical ingredients such as hormone growth regulators, etc.. The use of inappropriate can cause an endogenous hormonal imbalance in the body of the plant. This will continue on the interference with the enzymatic metabolism in plants, so it will affect on cell division and the provision of energy for plant metabolism. It can also cause an increase in ethylene hormone that causes hair loss and possible candidates for flowers.

Tips planting orchids



     1. 
Location, temperature and humidity: Orchids will grow well in the highlands (in the lowlands are also able to live, but must meet the exact requirements), the temperature ranges from 15-35 degrees Celsius (optimum temperature 21 degrees Celsius) with good air circulation. Humidity ranges from 65-70%.
   


     2. 
Sunlight: abstinence orchid plants direct sun, but still tolerant to the sun in the morning (between the hours of 7-9 am). Orchid less sunlight to grow thin, narrow leaves and long, on the contrary, if excess sunlight the leaves will turn yellow like fire. Orchids will grow well if hung in the shade of a tree.
  


     3. 
Watering: There is no set time to water the orchid. Practical way to find out if plants need watering is to monitor the condition of the media using the earnings. Watering should be with the sprayer and water that used free chlorine and other chemical compounds. More young orchids need a lot of water, watering should be 1 day 1 time. For larger orchids, 2 days is sufficient. Too much water will make the vulnerable orchid fungus that causes leaves and root rot. Orchids should not get wet because it will quickly fall.
  


     4. 
Fertilizing: Orchids need to be nurtured to make diligent flowering. Tips for choosing the right fertilizer is selected liquid fertilizer (foliar fertilizer), NPK macro elements must be adapted to plant age (young orchids require more N elements, while the orchid is ready to bloom require more P elements). Fertilization is done once a week with a dose of 1 / 2 teaspoon to 1 liter of water. Spray a solution of fertilizer with the sprayer on the leaves and roots. Fertilization can be done more often by reducing the dose.
  


     5. 
Media planting: Planting media is good is not fast rotten, facilitate root attached, hollow (porous) for air circulation, can store nutrients, and not easily become a source of disease. Kinds of media are the ferns, moss, coconut fiber, charcoal, wood, broken bricks or tile


     6. 
Pot: For the pot can be selected potting soil or plastic. Potting soil can store water, while the pot is not plastic. Orchids also good planted in blocks of ferns and hung under trees. Repotting should be done periodically, eg every 6 months to give more space on the roots of orchids.

Euphorbia Lively Flowers


The beauty of Euphorbia is when grown with blooming flowers. To get it is not difficult, just need accuracy and patience. First, let Euphorbia allowed to grow perfect before flowering. Here it takes patience to not enjoy the beauty of flowers while, because at this phase of each flower that appears directly potes (cut flowers without the tool, directly using the hands). This is done to stimulate the emergence of leaves and stems can grow exponentially. Each time the flowers appear immediately cut. Until felt was lush canopy. Furthermore, if the canopy was dense, left to grow new flowers. Within 2 weeks the flowers will meet canopy.

Plastic Silencer Heat to Bonsai


After doing the pruning, the growth of new shoots highly anticipated. However the young twigs that die when the sun, very disappointing. For that, use plastic wrap sticks with transparent until new shoots appear. On the plastic was made a hole for moisture stable. With this technique bonsai resistant to sunlight.
