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 acid 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 of 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).

Fertilizers must be rich in phosphorus, potassium and nitrogen. Buy 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.

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.
