How to grow gardenias so that they grow fast and lush (gardenia cultivation methods and tips)

How to grow gardenia well

1) Choose suitable soil

Gardenia is best cultivated in loose, fertile, well-drained, acidic soil with a pH of 5-6.

Gardenia cannot tolerate drought and poor soil. For home potted plants, leaf mold, peat soil, garden soil and river sand are often mixed in a ratio of 3:2:4:1. If the soil is alkaline or compacted and airtight, it is easy to cause the leaves of the gardenia to turn yellow and bloom sparsely.

2) Fertilizer and water supply needs to be timely

Gardenia likes fertilizer and water, which are its two major characteristics. Therefore, 10% alum fertilizer water is often used as topdressing in maintenance. When repotting in spring every year, more well-rotted cake fertilizer, sesame paste residue, tofu residue, etc. are applied as base fertilizer, which can promote the green leaves and abundant flowers of gardenia, without yellow leaves and fragrant flowers.

During daily maintenance, watering with a little citric acid solution can also keep the leaves green.

Watering should be timely, but not excessive. Water more in spring and summer to increase the humidity, and the bottom plate should retain water to facilitate its growth. Do not water too much in autumn, otherwise it will cause yellow leaves or even fall leaves.

3) Supplement phosphorus fertilizer during the bud formation period

Every spring, from April to May, the buds of gardenias are in the process of bud formation and bud expansion. During this period, phosphorus and nitrogen combined fertilizers should be applied 1 to 2 times in time. Fertilization should be stopped when the temperature is above 35°C in summer and below 15°C in autumn.

4) The placement should be appropriate

Gardenia prefers warm and humid climate and is not cold-resistant. It is best placed on a balcony or near a south window with sufficient light. Except for the summer period from July to early September when it needs to be shaded from direct sunlight, it can be given sufficient light in other seasons.

If there is insufficient light, the accumulation of nutrients will be less, the flowers will bloom less frequently during the flowering period, the flowers will be smaller, and the fragrance will not be strong.

In short, gardenia is a southern flower that likes acidic soil, moisture, fertility and sunlight. It should be cultivated in acidic soil, watering should be timely and sufficient, and fertilizer and water should be supplemented sufficiently.

Especially in spring, from April to May, when the gardenia buds are expanding and forming buds, phosphorus and potassium fertilizers need to be added. Only by grasping the above points can we maintain the gardenia that likes fertilizer and water well.
