Does gardenia need ferrous sulfate to bloom?
Abstract: This article discusses whether gardenias need ferrous sulfate to bloom and provides knowledge on how to deal with non-blooming plants, so let's check out the details with the editor!
Gardenias bloom around Qingming Festival every year, and the blooming period is mainly affected by temperature. Due to the relatively low temperature in the northern region of China, even after the beginning of spring, the temperature is around 5-6 degrees Celsius. Affected by low temperature, the blooming period of gardenias has to wait until April to May, while gardenias in the southern region can basically finish blooming by the end of March to early April every year.
Gardenia is relatively easy to cultivate for home gardening. It is a medium-sized woody plant. When well-cultivated, gardenia can grow into a tree shape, reaching up to 3 meters in height and 2 meters in crown diameter. Even for small potted gardenias at home, proper care can make them grow strong and robust.
The fragrance of gardenia is unforgettable. After the blooming period, the scent is very strong. Basically, anyone who likes gardening can recognize the appearance of gardenias. In the traditional floral plants of China, gardenias are also quite popular.
Does gardenia need ferrous sulfate to bloom?
The biggest problem with potted gardenias is that they don't bloom. Only two or three flowers bloom during the flowering period of a whole year, which is the most common problem in home cultivation of gardenias. The main reason for the small number of blooms is actually due to the lack of nutrients in the soil or insufficient sunlight.
All flowering plants need to be exposed to sunlight in spring, as sunlight is more conducive to plant photosynthesis. Only when plants are exposed to sufficient sunlight can their roots absorb nutrients and flower buds develop smoothly. Otherwise, it is difficult to achieve the effect of blooming in abundance.
In many cases, we think that the reason why gardenias at home do not bloom is the lack of iron elements in the soil. However, it is not actually the case that gardenias require a lot of iron. They need more to grow in an acidic environment. Some special plants prefer acidic growing conditions. When the soil is acidic, the plant's vitality is high, which also helps with blooming.
