What to do when a potted orchid won't bloom? It may be that the orchid seedling is not yet mature

I. What to do when an orchid won't bloom

The orchid is a beautiful yet understated flower. Earlier we discussed what to do when orchids get pests, and now let's look at what to do when an orchid won't bloom. Generally speaking, an orchid will not fail to bloom. There are many reasons why an orchid won't bloom; it may be that the orchid seedling has not reached blooming age, or it may be that the growing method is incorrect. Below, let's learn about the reasons why an orchid won't bloom.

II. Why an orchid won't bloom: it has not reached blooming age

1. The orchid seedling has not reached blooming age

Some orchids have been grown for several years without blooming. Why won't an orchid bloom? It is very likely that the orchid seedling has not yet reached blooming age. Similar to other plants, for example, trees must reach a certain age before they can bloom and bear fruit; orchids are the same, and only bloom once they reach a certain age. What you have just bought may very well be a small orchid seedling, still in the vegetative stage, with roots that have not yet spread out. What to do when an orchid won't bloom? It needs two years, slowly receiving nutrients and growing pseudobulbs, before it can possibly bloom.

2. Aging of the pseudobulbs

If it is not divided for many years, the pseudobulbs age as they grow, new roots do not develop completely, and nutrient uptake is also limited. At this point the plant does not have enough nutrients to supply blooming, so it should be repotted in time to promote root growth of the orchid plant.

3. Climatic differences

Every variety of orchid differs more or less, and the climate varies from region to region. These factors can all become reasons why an orchid won't bloom. For example, Cymbidium goeringii (spring orchid) is very difficult to bloom in some regions, and even when it blooms, it blooms relatively little.

4. Disordered growth

For various reasons, the growth of the orchid becomes disordered, and new leaf buds grow during the flower formation period, resulting in insufficient nutrients to sustain the development of the flower buds, so the flower buds stop growing and the orchid naturally cannot bloom.

III. Incorrect growing methods

1. Light

With less light, the accumulation of organic matter in the orchid plant is limited, unable to meet the needs of growth, let alone blooming. If the temperature is too low, the plant is prone to cold damage, and even if it does not die, it will not bloom. Only by ensuring a suitable temperature and increasing the temperature difference to accumulate enough nutrients can the orchid plant be encouraged to bloom.

2. Fertilizing

Improper fertilizing here refers to the fertilizing season and the combination of fertilizer elements. Continuing to fertilize in late autumn and winter leads to excess nutrients that stimulate the orchid so it cannot enter dormancy, reducing vernalization. And when the fertilizer elements are unbalanced, with too much nitrogen fertilizer, it causes the plant to grow leggy, with thick fleshy leaves, and even inhibits the differentiation of flower buds. The correct fertilizing time should be from April to July, mainly with nitrogen fertilizer and supplemented by phosphorus and potassium fertilizer; from July to August, mainly with phosphorus and potassium fertilizer and supplemented by nitrogen fertilizer. All of the above are reasons why an orchid won't bloom! What to do when an orchid won't bloom? Let's continue reading below.

IV. What to do when an orchid won't bloom

Dividing and scattering the plants destroys the orchid's habit of passing on reproductive genes through generations growing together, so orchids are best grown in clumps; grown singly, they have fewer leaves, accumulate less organic matter, and the reproductive genes have no way to become active. Generally, without three generations of pseudobulbs growing together in a clump, it is difficult for the orchid to bloom. If the orchid plant is still small, it does not possess reproductive genes. Some young seedlings that have not yet formed pseudobulbs need two years of vegetative growth to form pseudobulbs, then sprout new shoots two or three times, and only when three generations of branches grow together is blooming possible.

Solution: In July and August each year (the flower bud differentiation period for most orchids), appropriately control water for the orchid so the growing medium stays on the dry side. At the same time, spray the leaves with monopotassium phosphate once every 10—15 days, spraying two to three times in succession, which helps the differentiation and formation of orchid flower buds. The above covers what to do when an orchid won't bloom and the reasons why an orchid won't bloom. We hope this can help everyone.

How to grow potted orchids: orchid growing methods and precautions (water more, avoid strong light)

The orchid is a common potted flower in daily life. Since ancient times, many poets have written poems about orchids, and orchids, which bloom in all four seasons, are deeply loved by people. In daily life, many novice growers want to grow orchids but do not know how to grow them. Orchids are actually very easy to grow; as long as you understand the orchid growing methods and precautions below, you are sure to have orchids that bloom big and bright.

I. How to grow potted orchids: water more, sun less

Orchids bloom throughout the four seasons, and different orchid varieties have different flower colors. Since they bloom in all four seasons, you can probably guess that this flower is easy to grow. So how do you grow orchids? The first things to note are the watering technique and light. As long as you master these two points, your orchids will surely grow very well. Below we explain the orchid growing methods and precautions in detail.

II. Orchid growing methods and precautions

1. Care location

Throughout the four seasons, apart from winter when we need to keep orchids indoors to protect them from the cold and keep them warm, we can grow orchids outdoors during the other three seasons. In summer and autumn, when temperatures are high and sunlight is too intense, we need to provide semi-shade care. Orchids grown indoors are best placed in a ventilated, breathable spot, and need sufficient light; ideally they should be able to receive sunlight in winter.

2. Soil

The soil for orchids should be mainly humus, primarily using leaf mold or mountain forest humus soil. You can also use leaf mold, vermiculite, perlite, etc., to artificially prepare a loose, breathable, water-permeable growing medium.

3. Watering method

Watering orchids should be based on the species, growth conditions and local climate, aiming for moist but not wet, dry but not parched. Do not water too much or too little, and follow the principle of not dry in autumn and not wet in winter. In summer, when temperatures are high and orchids are in their vigorous growth period, water on average 1 to 2 times a day. In winter, when temperatures are low and the plants are in a dormant state, watering should be controlled, generally once every 5 to 7 days, but Cymbidium sinense (Chinese cymbidium), which blooms in winter, needs more water.

Precautions: When watering, be careful to prevent water droplets from splashing onto the leaves, so as to avoid black spots that affect the ornamental effect. During the orchid's growing period, the leaves should be sprayed with water regularly, and in summer water should also be sprinkled on the ground around the flowerpot to increase air humidity and promote the growth and development of the orchid. For water used to irrigate orchids, rainwater and snow water are best; if tap water is used, it should be stored for 2 to 3 days before use.

4. Light

Orchids prefer shade and are afraid of direct sunlight. However, they must not be kept in a dark place for a long time, as this will cause poor growth and even few or no flowers; appropriate light is very necessary. If we grow orchids indoors, we can place them on a flower stand by the windowsill or on a table, and we need to rotate the flowerpot every so often to prevent the plant from growing lopsided due to phototropism.

5. Fertilizing

Fertilizing is also very necessary when growing orchids. We generally follow the principle of applying thin fertilizer frequently, keeping the amount of each fertilizing to a small amount. We can use soybean cake water and apply it once every half month, and applying monopotassium phosphate once a month gives even better results. Generally in summer we do not need to fertilize, because summer temperatures are high and water evaporates easily, causing the fertilizer solution to become too concentrated and burn the roots.

III. Precautions for growing orchids

1. During orchid cultivation, withered yellow old leaves and diseased or pest-damaged leaves should be continually cut off to facilitate ventilation. After the flower buds emerge, each plant should keep one strong flower bud and cut off the rest, so as to avoid consuming too many nutrients and affecting next year's blooming. After the flowers fade, the flower scapes should be cut off.

2. In [winter] pay attention to cold protection. Terrestrial orchids are strongly cold-resistant, while tropical orchids require a higher overwintering temperature and should be moved indoors early or protected with a plastic shed to avoid freezing; the room temperature is best kept at 10 to 15°C, and ventilation should be noted when keeping them indoors. As the climate gradually warms in spring, the orchids can gradually be moved to the courtyard or balcony.

3. For home orchid cultivation, natural rainwater, stream water, well water and river water are best. If tap water is used, it should first be stored in a vat and exposed to the sun to remove the bleaching powder before use. If tap water is used to water flowers for a long time, it will gradually make the growing medium alkaline. Ferrous sulfate can be applied once every so often to increase soil acidity. In addition, watering orchids with fermented rice-washing water can also keep the soil in a slightly acidic state.

How to promote blooming in potted orchids? Small tips for promoting blooming in potted orchids

Orchids can also be called Chinese orchid, spring orchid, secluded orchid, mountain orchid, national fragrance, fairy of the empty valley, and ancestor of fragrance. The entire growth process is divided into two periods: the vegetative growth period and the reproductive growth period. In recent years, whether growing orchids in greenhouses or promoting the construction of underground orchid rooms, there are shortcomings, so how to promote early blooming of orchids under simple and crude conditions has become one of the issues of concern to the broad community of flower lovers. Next, the editor will briefly talk about small tips for promoting blooming in potted orchids, hoping it can be of some help to everyone.

1. Fertilizing to promote blooming

Anyone who has grown orchids knows that to speed up orchid growth you apply nitrogen fertilizer, but you should know that phosphorus and potassium fertilizers are essential nutrients for orchid blooming. Therefore, to promote orchid blooming, you can mix 10%-20% (by volume) bone charcoal into the medium. Bone charcoal is rich in phosphorus and has a long-lasting fertilizer effect, which is very beneficial for orchid blooming. At the same time, you can also apply monopotassium phosphate one month before the orchid's flower bud differentiation, raising the monopotassium phosphate concentration to 0.3%-0.4%, which helps the flower buds differentiate early, but during the flower bud differentiation period, avoid applying too much nitrogen fertilizer.

2. Small pots to force blooming

Orchid roots like air. When potted with poor aeration, the orchid seedlings in the center of the pot are prone to root rot and collapse. Orchids grown in small pots bloom easily, so it is best to use smaller-diameter unglazed clay pots to plant orchids. When planting, trim the original rotten roots and shorten the longer orchid roots, and at the same time apply plant ash to the pruning wounds. This can make the newly grown orchid roots short and dense, stimulate flower bud differentiation, and thus achieve the effect of forcing blooming.

3. Strong stems benefit blooming

The orchid's pseudobulb is a warehouse for storing water and nutrients. When the pseudobulb is large, it indicates that more nutrients are stored; conversely, fewer nutrients are stored. Orchid flower buds mostly sprout from relatively large pseudobulbs, while weak, small pseudobulbs have greater difficulty sprouting flower buds, so growing strong pseudobulbs is beneficial for orchid blooming. At the same time, during orchid cultivation, 0.2% monopotassium phosphate should be sprayed frequently. This not only promotes blooming but also enables the pseudobulbs of new orchid seedlings to swell quickly, meeting the plant's needs for blooming.

4. Withholding water to hasten blooming

When a leaf-stalk ring appears at the leaf base of each leaf of the orchid plant, it indicates that the orchid plant has matured and entered the flower bud differentiation period. After the orchid plant enters the flower bud differentiation period, the amount of watering should be appropriately controlled, keeping the potting soil on the dry side, which can raise the cytoplasmic concentration and promote flower bud differentiation.
