Gardenia: acidophilic plant
It is important to take care of the substrate ofcultivation. Theregardenia in potneeds different care they see:
- frequent watering
- containment pruning
- pruning to stimulate flowering
- regular fertilizations
- always acidic substrate
To keep the soil acidic, you should never use tap water for irrigation. Tap water, if rich in limestone, will raise the pH of the soil making it alkaline and unsuitable for growinggardenias.
How to water the gardenia?
Just use rainwater or distilled water. If you have an air conditioner, you can also use the water from the conditioner to irrigate the gardenia. The water in the domestic air conditioner is nothing more than demineralized water: perfect for irrigating indoor plants, especially if they do not tolerate basic soil.
Note: ideally, rainwater should be used, but in summer, with drought, green light for the air conditioner to water the gardenia.
As is clear, great attention must be paid to the ground, especially when it comes togardenia cultivation in pots: the quantity of substrate is limited so it must be taken care of in the structure, in the pH reaction and in the availability of nutrients (fertilization).

How to prune gardenia in pots
For thecultivation in potscontainment pruning will be necessary where you will cut too old branches, castings at the base or dead branches. Pruning should take into account the cultivated species.
If you wantprune the gardeniato stimulate itflowering you have to perform a said practiceblossoming. It is performed near flowering and consists in manually eliminating the excess flower buds. Typically, igardenia flowersthey develop singly or in groups of two or three buds… when there are excess buds, eliminate them. This practice (blossoming) will guarantee you larger flowers, with more vivid colors and above all that the plant will be able to keep longer.
Theregardenia in the housemust have someextra watering. Very useful, forgardenias in potsgrownin home, are the foliar nebulizations especially in too dry environments and in the presence of air conditioning systems (radiators or summer conditioners). Leafy sprays are even more useful near flowering.
Fertilize the gardenia: fertilizer
The gardenias they are demanding plants. Fertilization must be performed every 15 days from February to May and from the beginning of September until the end of October. Fertilizers must be rich in phosphorus, potassium and nitrogen. Purchase a fertilizer for acidophilic plants and remember to suspend fertilization in the summer (from June to August) and from November to January.
An excellent fertilizer for gardenia is the one with NPK (nitrogen, phosphorus and potassium) contribution 13-7-13. Also in this case you can find the product online or in garden centers. On Amazon an excellent fertilizer for acidophilic plants can be bought with 4.02 euros and free shipping.
Useful link from Amazon: Water-soluble fertilizer for acidophilic plants.
Please note: Our website has no connection with the manufacturer of the indicated fertilizer. We have reported that only for the balanced supply of nitrogen, phosphorus and potassium. If thegardenia does not bloomin fact, perhaps you are adding the wrong fertilizer.
A fertilizer that is too rich in nitrogen stimulates the production of leaves and green parts, inhibiting the production of flowers. It is for this reason that it is advisable to choose a fertilizer for acidophilic flowering plants with an NPK ratio as indicated.
