What kind of soil is good for gardenias? How can gardenias survive?

Gardenia has white petals, a light fragrance, and is easy to survive on the roadside, so it is very suitable for home cultivation. So should I use acidic soil or alkaline soil to grow gardenia? How can I grow it so that it can survive?

What soil is best for gardenias?

The most important thing about the soil for gardenia is slightly acidic soil. As one of the acidic flowers, this directly determines whether gardenia can be grown well.

When preparing the soil, you can add some slightly acidic soil, such as leaf mold, sawdust, etc., which are slightly acidic. The pH value should not exceed 7.

There are many options for soil preparation. In the south, you can use 7 parts red soil and 3 parts leaf mold. The soil in the north is alkaline, so you should add more leaf mold, garden soil, leaf mold, and river sand and mix them in a ratio of 4:4:2.

How to plant gardenia and keep it alive

Lighting requirements

Gardenia is a semi-shade flower. The ideal semi-shade environment should receive about 50% sunlight. For outdoor maintenance, it can be placed in a flower sun under a tree. For indoor maintenance, it should be placed in a well-lit place. Insufficient light will cause poor growth of gardenia and yellow leaves.

Gardenia Fertilization

Gardenia likes fertilizer, so it is necessary to fertilize frequently during the growth period. In order to meet the needs of gardenia for an acidic environment, try to use acidic fertilizers. For example, decomposed cake fertilizer water, alum fertilizer water, etc. When maintaining in the north, you can add some acidic substances, such as vinegar, citric acid, ferrous sulfate, etc. The frequency of fertilization is generally once every 7-10 days. After the flower buds are formed, phosphorus fertilizers can be used to promote flowering and make the flowers more colorful.

Watering Gardenia

Gardenia likes a humid growing environment. Normally, just water it to keep the soil moist. The amount of watering depends on the season and weather conditions. Water more in summer when the temperature is high, and water less in winter. In rainy seasons, drain the water in time to prevent water from accumulating in the pot soil.

In addition to watering the roots, in dry seasons or areas, you should spray water on the leaves to achieve the purpose of humidification. You can also use a humidifier for humidification.

Gardenia pruning

Gardenia has a strong ability to sprout and is prone to forming overlapping branches. It needs to be pruned frequently during the growing season. When new buds sprout, some inner buds should be removed in time, and the inner branches should be thinned to ensure ventilation and light transmission. After flowering, the branches should be cut short to promote the sprouting of side branches.

Can gardenia be grown in the north?

You can plant it.

Soil: The requirements for choosing cultivation soil are good permeability and water and fertilizer retention capabilities, preferably loam.

Fertilization: Apply appropriate and reasonable fertilizer during the growing period. Fertilizer can be applied two or three times a month. Be sure to cut off water before applying fertilizer. Use cake fertilizer water when applying fertilizer. Water thoroughly after fertilizing. Generally, no fertilizer should be applied until September.

Temperature: The most important point in growing gardenias in the north is to maintain the ambient temperature, and the flowering temperature of gardenias is usually above 27 degrees. If the ambient temperature of gardenias is very low, yellow leaves will appear and wither, and they should be moved to a warmer environment in time.

Watering: Gardenias have a relatively large demand for water, especially in dry weather, and need to be watered two or three times a week. In addition to daily watering, pay attention to the humidity conditions in the room, use a humidifier or spray water on the flowers through a spray basin to ensure the humidity of the environment.
