How many times a year does a gardenia bloom, how many years must you grow it, and how do you plant it so it flowers?

In a few more months, it will be time for gardenias to bloom in full, and the flowers that gardenias produce can not only be steeped as tea but also have high ornamental value, so many people like to grow them on their own balconies. So how many times a year does a gardenia bloom? How many years must you grow it before it flowers? How do you plant it so it flowers?

How many times does it bloom in a year?

Under normal conditions, gardenias open one after another from mid-April to late May, and early June is the full bloom period for late-flowering varieties. But under natural outdoor conditions, a gardenia really can bloom in two seasons a year. This is because the temperature and humidity and the natural ecological environment of spring and autumn suit the flowering habits of the gardenia, and the gardenia itself naturally has the trait of flowering in two seasons a year. Many greenhouse flowers today can bloom several times a year, or bloom out of season, but that is artificially changing the plant's growth characteristics, not a natural trait of the plant. It should not count as a rare or unusual flower species, though it is rare for one to bloom in three seasons a year outdoors. Its ornamental value rises, and when it meets someone who likes it, its value naturally rises too!

How many years must you grow it before it flowers?

The gardenia likes a warm, humid, semi-shaded environment, tolerates light shade, and fears strong direct sun. Its flowering period is fairly long, blooming continuously from May to June until August, with the fruit ripening in October. But a single flower lasts only 4-5 days. With ample fertilizer, there are more flower buds and the flowering period is a little longer.

How do you grow it so it flowers?

1. Soil

The gardenia is an indicator plant for acidic soil, so a slightly acidic soil environment is the key to determining whether a gardenia grows well or poorly. The growing medium should be a mix of 7 parts slightly acidic sandy red soil and 3 parts leaf mold. It is best to keep the soil pH between 4.0 and 6.5.

2. Temperature

The best growing temperature for gardenia is 16°C-18°C. Both too-low temperatures and direct sunlight are extremely harmful to its growth, so in summer the gardenia should be kept in a well-ventilated, humid, light-filtering open woodland or shade shed. In winter, keep it in an environment with sunlight and a temperature not below 0°C, and let it go dormant; too high a temperature will affect flowering the following year.

3. Water

The gardenia likes humid air, and during the growing period watering should be increased appropriately. Usually you can water once the potting soil turns pale, watering thoroughly each time. In the hot summer, mist the leaves 2-3 times a day to increase air humidity and help the plant cool down. But after the flower buds appear, do not water too much, to avoid bud drop. In winter, it is better to keep watering on the dry side, to prevent root rot from excess water.

4. Fertilizer

The gardenia is a plant that likes fertilizer. To meet its fertilizer needs during the growing period while keeping the soil slightly acidic, you can first mix ferrous sulfate into the liquid fertilizer and let it ferment. After entering the peak growing season in April, you can apply a top dressing once every half month (when fertilizing, it is best to dilute with plenty of water to prevent burning the flowers). This meets the gardenia's fertilizer needs, keeps the soil environment in a relatively balanced slightly acidic state, prevents the occurrence of chlorosis, and at the same time avoids the harm to the gardenia from a sudden ferrous sulfate supplement making one spot too acidic.

5. Propagation

Although there are many ways to propagate gardenia, the simplest and quickest is the floating water-cutting method. First find a piece of foam board and punch holes in it, cut off half-ripened branches of the current year from the gardenia, insert them into the holes in the foam board, then place the foam board into a bucket full of water, and put the bucket in an environment that both shades the floating board's cuttings and lets sunlight reach the bucket. Keep the water temperature between 18°C-25°C, and the gardenia can grow roots more than 3 cm long in one week. Propagating gardenia this way gives a survival rate of 100%.
