Gardenia not blooming? Ferrous sulfate alone won't work, add a little something and the flowers will be big and fragrant
This season is the best time to care for gardenias, fresh and elegant, with a fragrance that hits you right in the face. Use a bit of this special bloom-boosting agent, and the flowers will be big and fragrant, growing 10 buds at a time! But many gardening friends say that using ferrous sulfate alone doesn't work. Let me teach you how to do it, add a little something extra, and the flowers will be big and fragrant!
The "something extra" mentioned refers to citric acid. On top of using ferrous sulfate for gardenias, add some citric acid to acidify the soil, making it more suitable for gardenia growth!
Citric acid and ferrous sulfate are the golden partners for gardenias. Occasionally give gardenias some citric acid and ferrous sulfate, and the gardenias will bloom continuously with a rich fragrance. Keep them indoors and you won't even need an air purifier.
Citric acid and ferrous sulfate should be used together, and the effect is better than using them alone. It can not only prevent yellow leaves, but also change the soil pH, adjusting it to an environment suitable for gardenia growth. Only then will the gardenias grow better and better, growing multiple buds at a time, with flowers blooming one after another!
Specific method
Dilute citric acid and drip it into the soil. This can change the soil pH and make the soil acidic. As everyone knows, gardenias grow best in acidic soil, and in alkaline and neutral soil they grow slowly and bloom less. So using citric acid plays a very important role.
While changing the soil pH, you can spray the leaves with a ferrous sulfate solution to increase the leaf's absorption rate of iron ions, prevent gardenia yellow leaves, and make the leaves more emerald green. It can also be used for watering to make gardenias bloom white and fragrant. However, when using ferrous sulfate, it is recommended to prepare and use it fresh to achieve a certain effect.
It's that simple. That's all for today's sharing!
