If there is not enough light, its flower buds cannot differentiate, so the phenomenon of only growing leaves and not blooming occurs. If the longevity flower is not pruned for a long time, its branches and leaves will become too vigorous, which can also lead to the phenomenon of only growing leaves and not blooming. The reason why the longevity flower only grows leaves and does not bloom may also be excessive watering, so watering the longevity flower should not be too frequent.The longevity flower is a perennial herbaceous plant loved by many flower enthusiasts. Its leaves are thick and lush throughout the year, and the plant is not too large. Even without blooming, it has high ornamental value. So why doesn't the longevity flower bloom but only grow leaves?The longevity flower only grows leaves and doesn't bloom1. Insufficient lightingThe longevity flower is a short-day plant. If there is not enough light, its flower buds cannot differentiate, so the phenomenon of only growing leaves and not blooming occurs.When maintaining the longevity flower, it needs to be placed in a well-lit area, generally with 8-9 hours of sunlight per day, and it can bloom in about 3-4 weeks.2. Improper fertilizationThe reason why the longevity flower only grows leaves and doesn't bloom may also be due to improper fertilization, such as applying too much nitrogen fertilizer, which can cause this phenomenon.During the flower bud differentiation period of the longevity flower in autumn, less nitrogen fertilizer should be applied, and more phosphorus and potassium fertilizers should be applied, so that its flowers can grow and bloom.3. No pruningIf the longevity flower is not pruned for a long time, its branches and leaves will become too vigorous, which can also lead to the phenomenon of only growing leaves and not blooming.In case of this phenomenon, it is necessary to prune the longevity flower in time, pinch the growing branches, and some weak, dense, and aging stems and leaves can be cut appropriately.4. Excessive wateringThe reason why the longevity flower only grows leaves and doesn't bloom may also be excessive watering. Watering the longevity flower should not be too frequent.During its growing period, keep the soil slightly moist, otherwise, improper or excessive watering for a long time can lead to adverse phenomena such as yellow leaves and rotting roots in the longevity flower.5. The plant is too oldThe age of the longevity flower also affects the blooming of the plant. Usually, the branches of 1 or 2-year-old longevity flowers have more vitality and are easier to bloom. For old stakes of longevity flowers, they are not as blooming as 1 or 2-year-old ones.To address the non-blooming caused by plant age, you can propagate the longevity flower every 2 years to keep the plant in a young state, which can lead to more blooming.How to care for the longevity flower after autumn1. Avoid too much sun exposureThe longevity flower is a short-day plant. It only needs to be exposed to the sun for a few hours in the morning or evening, and the rest of the time, it should be placed in a shady place.2. Control water to prevent black rotHigh humidity is the main cause of black rot. In early autumn, the temperature is still relatively high. If water is not controlled, it can cause waterlogging in the pot, which can lead to bacterial growth and black rot.3. Prune branchesCut off all remaining, withered, and growing branches, and also prune dense branches to ensure normal photosynthesis.The longevity flower topped to promote bloomingTopping the longevity flower generally needs to be done in spring and autumn, which is more conducive to blooming. Otherwise, it is prone to continuous growth, only growing leaves, and the plant keeps getting taller without blooming.The growth state of the longevity flower in spring and autumn is relatively good. When topping the longevity flower, it should not be too short at the beginning, at least leaving 5-6 centimeters to ensure its basic growth. We can also prune overly tall and dense branches, which is more conducive to the growth of the longevity flower.The above is a detailed explanation of why the longevity flower doesn't bloom but only grows leaves.
