Why doesn't Hippeastrum bloom?
If you want to understand why Hippeastrum doesn't bloom and the related introduction of green plant flowers, including the cultivation knowledge for Hippeastrum to bloom, the specific content is as follows:
Hippeastrum is a type of bulbous flower, and many people purchase it every year because its blooms are very beautiful. When cultivating Hippeastrum at home, the bulbs bought are often already differentiated into flower buds, which means they start growing flower spikes and blooming after planting. Some may even bloom without producing leaves. However, after later-stage care, such as repotting, many gardening enthusiasts find that it doesn't bloom in the second year. What is the reason for this?
The first reason why Hippeastrum doesn't bloom is that it hasn't gone through a dormancy stage. Unlike other plants, Hippeastrum requires a process of low-temperature vernalization. This means keeping the temperature between 5 to 10 degrees Celsius, where it is in a state of slow growth and short-term dormancy. This period is when the flower buds in the bulb are differentiated. After a month or more, the flower buds are fully differentiated, and when planted, they can grow flower spikes and bloom. If you don't provide such a period for it, the flowers won't grow, and it will only produce leaves.
This leads to the situation where Hippeastrum can bloom in the first year in the south because it already has flower buds when bought. However, in the second and third years, it may only grow leaves and not bloom. If you are in the south and want to make it bloom, you can cut the leaves, trim the roots, wrap it in something like cotton, and place it in the constant-temperature compartment of your refrigerator with a temperature between 5 to 10 degrees Celsius for over a month. After that, plant it, and it will be able to grow flower buds and bloom.
The second reason for not blooming could be that the bulb we bought is small, or it might be a newly formed side bud. If the bulb is small, it won't be able to differentiate flower buds, and the nutrients won't be sufficient. If the bulb is small, allow it to grow for one or two years to make it larger, then use the low-temperature dormancy method to quickly differentiate flower buds, which will enable it to grow flower buds and bloom.
Why doesn't Hippeastrum bloom?
Hippeastrum is considered an easy-to-care-for plant. If it doesn't bloom, the main reason is that it hasn't gone through dormancy and thus hasn't differentiated flower buds. In everyday care, we don't need to use a pot that's too large, just one or two sizes bigger than the rhizome is fine. The soil should be as breathable as possible and avoid using deep pots for cultivation.
Water the plant when the soil is dry to a depth of one or two centimeters, and make sure to water thoroughly. When planting, don't plant it too deep, just cover half of the bulb. Choose fertilizers high in phosphorus and potassium and keep supplementing it. The bulb will grow larger and continue to produce small side bulbs. When it blooms, it will definitely be able to bloom in full.
