Reasons Why Cymbidium Orchid Buds Shrivel, Turn Yellow and Drop, and Post-Bloom Care Methods

Cymbidium orchid, also known as Himbi orchid and cicada orchid, belongs to the Orchidaceae family and Cymbidium genus, a perennial evergreen herb, height 30-150cm"big brother" among Chinese New Year flowers, with bold and unrestrained, magnificent flowers, combining the delicate fragrance and elegance of Chinese orchids with the rich variety of Western orchids, it is a "rising star of orchids" in the world, and for so many years, its popularity has only increased. It is not - -a one-time plant either, so by no means throw it away after the flowers are gone; with good care it can bloom again at the end of the year.

Reasons Why Cymbidium Orchid Buds Turn Yellow and Drop and How to Handle It

There are two reasons why Cymbidium orchid buds turn yellow and drop. One is temperature: the suitable growing temperature for Cymbidium orchid is between 15 and 25 degrees, but in many flower lovers' homes the temperature rises and falls, or the difference between day and night is too great, which affects the growth and blooming of Cymbidium orchid and easily causes buds to turn yellow, drop and abort; the second is watering: many flower lovers may water too much or in the wrong way, which can also easily cause bud abortion. When growing Cymbidium orchid, you need to control the watering frequency; you can water once every 1-2 weeks, and you should apply potassium dihydrogen phosphate to the Cymbidium orchid, and place it in an environment with a temperature of about 10 degrees. So when we encounter bud abortion, how should we handle it? The aborted buds can no longer open normally, so we can simply cut them off with scissors, then improve the care environment so that the other buds can continue to open normally one after another.

  I. Care During Blooming:
     1. A newly purchased Cymbidium orchid that is already blooming does not need to be repotted right away; this prevents root damage that would stop it from blooming, so wait until the blooming period is over before repotting.
     2.Place the Cymbidium orchid in a spot near a window with bright indirect light; if the light is too dim, it easily causes bud abortion.
     3.Cymbidium orchid likes a cool, semi-shaded environment with plenty of indirect light; try to keep the room temperature above 10°C
     4. Cymbidium orchid likes water but dislikes waterlogging; water promptly once the soil is dry. When watering, avoid pouring from the top down; just water the soil surface. If the pot is too full, you can use the soak-watering method. While the buds have not opened, you can add some flower fertilizer to the water. If the buds are half open, no fertilizer is needed, otherwise they tend to finish blooming early.
  II. Preparing for Reblooming
     1.Watering

When the bark is about to dry out, water thoroughly. In spring and autumn, watering is generally about once a week in summer it may need watering in less than a week, and watering in the morning is better to avoid high temperature and high humidity; in winter, water generally once every half month.

2.Fertilizing

After blooming, apply light fertilizer frequently; you can add some orchid-specific fertilizer each time you water. In summer, when high temperatures bring on dormancy, you can skip fertilizing. After temperatures drop in autumn, you can alternate potassium dihydrogen phosphate with a balanced fertilizer, so that the next blooming will be even more abundant and vivid.

3.Light

In spring and winter, when the sunlight is soft, it can be exposed to direct sun; in summer and autumn, when temperatures are high, do not let the Cymbidium orchid bake in the sun, and move it to a place out of direct sunlight; after temperatures drop in autumn, sun exposure helps it bloom.
     4.Pests and Diseases

A poor growing environment makes it prone to pests and diseases. Common diseases include black rot, soft rot, anthracnose, gray mold, and southern blight; normally you can spray a fungicide once every half month to prevent diseases, and pay special attention to ventilation in the environment.
