Gardenia is a charming shrub of family Rubiaceae, native of South-East China and Japan were is moderate temperature and high constant moisture.
Gardenia is, as we said before, a very appreciated shrub, 1- 2,5 meters weight, bushy and with a slow growing. Its leaves are dark healthy green, glace and having between 5 and 10 centimeters (for potted plant). Gardenia’s flowers are most loved because of their perfume very alike jasmine’s flavor. They are white or light cream colored and seam to be waxen. Gardenia has oval orange fruits, not very decorating elements.
Gardenia flowers in the middle of spring or the beginning of summer and this process will last some and we can admire the flowers for a long period because they dont bloom all at once. But the plant requires special care during the flowering period. Very important are the light and especially temperature (it has to be 15-18 degrees at night and 22-25 degrees during the day). Any sudden temperature variation could be a real damage for its precious flowers. We have to point out that, when Gardenia buds, you are no more allowed to remove the pot or to break its dead leaves or clean.
Gardenia’s requirements and needs are very specific and you have to defer to them if you want to insure that your plant will continue to bloom next year too.
It loves full light and full sun too, but not in the summer, when is good to keep it with some shading. If you have a potted plant grown indoors, you must avoid the direct hot sun, just allow it only to get bright light. It’s appropriate to put the pot at the window towards south.
Gardenia is a plant that needs moisture and especially humidity to do well. It doesn’t bear the dried air, so put near the potted Gardenia a plate full of water to maintain the proper humidity. It’s also good for it to sprinkle the leaves, never its buds, because they will fall down. High humidity will also prevent the red spider infestation.
During hot period water more your Gardenia, keeping the soil always moist, especially in blooming. That will help buds to continue their flowering process and not to fall and also not to fail to form. Water it from above to downward, we mean to water the soil, never put water in its pot plate. But, don’t over water the plant. We said that you have to maintain the soil moist, but never soggy, because that will also affect Gardenia.
Gardenia needs an acid soil with a pH between 5 and 6, containing peat moss and compost. The perfect soil has to be a mix of organic elements (peat, pine needles, moss sphagnum, pine crumbled bark) that insure the porosity for a good water retention and some inactive materials (rubble without limestone, pearl stone) that help the drainage. Add above some pine needles too to keep the humidity in a high level.
The pot for your Gardenia is good to be from a proper material even plastic, so the water never will undergo.
Don’t forget to fertilize Gardenia. Feed the plant every three weeks during the growing season with a rhododendron-azalea food, or acidifying fertilizer.
You can propagate your Gardenia through cuttings, in February, but you can also obtain it through roots’ partition, but only when temperature range is at 27 degrees centigrade.
