Why don’t the gardenia buds grow bigger, turn black and fall off? What should I do?

1. Reasons why flower buds do not grow

1. Improper water and fertilizer: If gardenias have sufficient water and fertilizer during their growth period, it can easily cause them to grow too tall, resulting in the flower buds not growing but only growing in size. Or this phenomenon may occur if the fertilizer is too single or there is too much nitrogen fertilizer.

2. Unsuitable soil: It prefers acidic soil for growth. If the alkalinity of the soil is too high during maintenance, it may result in no flowering and no growth of flower buds.

3. Unsuitable light: It is a light-loving plant. If the light is not sufficient during maintenance, even if there are flower buds, it will not continue to grow and will not bloom.

2. Solution to blackening and falling

If its flower buds have turned black and fallen off, there is no way to save them. You can only use scissors to trim the branches and buds that have fallen off in time to prevent the wound from continuing to consume nutrients. After handling it, we need to find out the specific cause and then take appropriate measures to suppress it. If the water and fertilizer are inappropriate, it should be moved to a well-ventilated place in time, water should be strictly controlled, and fertilizer should not be applied any further. If there is insufficient light, you should move it to a place with scattered light and let it get more sun. In addition, its flower buds must not come into contact with water. If they are accidentally stained with water, they must be cleaned with a cloth in time.
