Six Major Reasons Why Amaryllis Doesn't Bloom and How to Fix Them
Some flower enthusiasts may have encountered this situation: the amaryllis they planted only grows leaves without blooming, and there are also cases where it never blooms when the flowering season arrives, which is very frustrating. So what causes amaryllis not to bloom? What should be done when amaryllis doesn't bloom? Today, the editor has compiled several common reasons and solutions.
What Causes Amaryllis Not to Bloom
1. Not yet at flowering age
Among the propagation methods for amaryllis, sowing seeds is one of the commonly used methods, but it generally takes 2-3 years from sowing to flowering. If this propagation method was used, then what causes amaryllis not to bloom? The answer is that the amaryllis may not have reached flowering age yet. This can be judged by the diameter of the bulb; only when it exceeds 5 cm can it possibly bloom.
2. Nutrients dispersed
During the cultivation of amaryllis, its bulb will sprout many small bulbils. If there is no need for propagation, the excess small bulbils should be removed during normal cultivation to prevent them from consuming extra nutrients, which would result in insufficient nutrition.
3. Insufficient nutrients
Amaryllis requires a large amount of nutrients from growth to flowering. If nutrients are insufficient during planting, it will cause failure to bloom. The main source of nutrients is fertilization, so fertilizer must be supplemented in a timely manner.
4. Too much nitrogen fertilizer applied
When fertilizing, if there is too much nitrogen fertilizer and too little phosphorus and potassium fertilizer, it will also cause only leaf growth without blooming. Therefore, during normal fertilization, especially before the flowering season arrives, phosphorus and potassium fertilizer should be added.
5. Bulb planted too deep
Normally, the amaryllis bulb should not be planted too deep, otherwise it is not conducive to flowering. Experienced flower enthusiasts have summarized a saying: deep planting produces offsets, shallow planting produces flowers, which means that planting too deep will not produce flowers. One third of the bulb should be left exposed above the surface.
6. Insufficient light
Whether during the growing period or the flowering period of amaryllis, sufficient light must be ensured, otherwise failure to bloom is very likely to occur.
What to Do When Amaryllis Doesn't Bloom
1. Reasonable fertilization
In spring, topdressing is needed 1-2 times, mainly with compound fertilizer. This is the critical period for amaryllis to sprout flower buds, so nitrogen fertilizer should be the main component. In summer, phosphorus and potassium fertilizer should be the main component. Avoid excessive fertilization.
2. Repot at the right time
Some flower enthusiasts use the same pot for many years without changing the soil when growing amaryllis, causing the soil to become too poor. Combined with not paying attention to fertilization, this results in insufficient nutrients for amaryllis growth. The pot and soil should be changed once every 1-2 years.
3. Increase light
In spring and autumn, amaryllis can be grown under full light conditions. In summer, it should be placed in a ventilated and shady place for care. Only with sufficient light can flowering be ensured and the flower colors be more vivid.
Reasons why amaryllis doesn't bloom, and solutions for amaryllis not blooming
Amaryllis, also known as baiqulian, zhudinglan, etc., is a perennial bulbous flower of the Amaryllidaceae family. Amaryllis prefers warmth and moisture, and dislikes strong light and exposure. Recently, a friend said that the amaryllis they planted does not bloom and they don't know how to solve it.
Basic information about amaryllis:
Amaryllis leaves are opposite on both sides, strap-shaped, with acuminate tips, 2-8 leaves. The leaves mostly emerge after the flowers, and are 15-60 cm long. Because amaryllis has many different varieties, it is widely grown in pots and has high ornamental value.
Reasons why amaryllis doesn't bloom, and solutions for amaryllis not blooming:
① Lack of fertilizer. After flowering each spring, apply compound fertilizer mainly composed of nitrogen fertilizer. In summer and autumn, apply compound fertilizer mainly composed of phosphorus and potassium fertilizer.
② Inappropriate light. Apart from shading when summer light is extremely strong, it is best to provide sufficient light at other times, especially in spring and autumn.
③ Moving indoors too early. Do not move it indoors too early in autumn. It is best to move it indoors only when the outdoor temperature reaches about 5°C.
④ Improper winter storage. In winter, it can be left in the pot soil without being removed and placed in a well-lit area at a temperature of about 5°C. It should not be too high. Wait until before Spring Festival to gradually raise the temperature. Only this way is it beneficial for flower bud germination.
⑤ Do not plant too deep. Only bury the root system or half of the bulb. Do not bury the entire bulb in the soil, otherwise many small bulbils will grow, but flowering will be rare or poor.
⑥ Wrong soil. It is best to cultivate with loose, fertile, well-drained sandy loam rich in humus. If clay soil is used for cultivation, it is also not conducive to flowering.
The above introduction by the editor must have given everyone a deeper understanding of amaryllis, as well as an understanding of the reasons why amaryllis fails to bloom and the solutions.
I hope this is helpful to friends who grow amaryllis!
