What fertilizer does gardenia add?

Applying decomposed cake fertilizer every half month (the residue after oil extraction in the workshop) is the key step for gardenias to bloom more and more beautifully.

Before planting gardenia, add organic fertilizer (decomposed animal manure and cake fertilizer) into the soil and mix it evenly with the soil. In April, potassium dihydrogen phosphate is sprayed once a week until flower buds appear in most branches of the whole gardenia. After budding, watering the roots twice with potassium dihydrogen phosphate can enhance the stress resistance of the plants and promote the flowers to be big and fragrant. But as long as the buds crack and turn white, fertilization will stop.

Of all the flowers, gardenia has a high demand for fertilizer.

Gardenia likes an environment with sufficient light and good ventilation, but it should avoid strong light. It should be planted in loose and fertile acid soil with good drainage. It can be propagated by cutting, layering, dividing plants or sowing.

Extended data

Gardenia needs acidic soil. It is suggested that humus soil, peat soil and garden soil should be selected as cultivation substrates, and old wall soil and cinder should never be used. Gardenia doesn't grow well in this alkaline soil.

Too dense branches will affect the ventilation of gardenia, so we should trim the redundant branches at any time to keep proper ventilation between branches and leaves, which not only makes the plants more beautiful, but also greatly reduces the occurrence of pests.

Besides ornamental, its flowers, fruits, leaves and roots can all be used as medicine, which has the effects of purging fire, removing annoyance, clearing away heat and diuresis, cooling blood and detoxifying.
