The Content Of The Article:

The gardenia is actually one of the classic indoor plants. Under certain conditions, the plant with the wonderfully fragrant flowers can also be cultivated outdoors.

Plant gardenia

The gardenia is much more than a flower for the buttonhole. It's not just romantics who swarm at the sight of the sweet-scented flowers, which seem to be made of wax, and the orange berries that follow the flowering in early summer.

In its homeland, the tropics, the gardenia can reach heights of growth of up to 1.5 meters. In our latitudes, the popular houseplant is only about half as high, but without losing any of its attractiveness.

Finding the right location

More than 250 gardenia species are known worldwide. In the tropics and subtropics, the plants usually grow as a shrub, some species as small trees. The climate in our latitudes, makes it impossible to cultivate the tropical plant in the field all year round. Therefore, the gardenia has priority as a houseplant.

" Tip: The gardenia may be spent on the balcony or terrace during the summer. Slight temperature swings between hot days and rather cool nights do not harm the plant, but correspond to the habits of the natural habitat of plants and stimulate flower formation.

The gardenia needs a bright location. In this case, the full sunlight is to be avoided. An east or west window is preferable to the sunny south window. Placed on the south window, you should be protected from the blazing midday sun. Accordingly, the location outdoors during the summer months to choose - bright, protected and partially shady.

The outdoor stay should be restricted to the months of July and August for the gardenia. Temperatures below 15 degrees do not get the plant and the gardenia then throws off their buds. The same happens at temperatures over 25 degrees. Ideal are constant temperatures between 20 and 24 degrees, while flowering is slightly lower.

" Tip: Gardenias need a high humidity as tropical plants and should be sprayed more often.

In short:

  • bright
  • protected
  • warm
  • penumbra
  • high humidity

Select the ideal substrate

For the gardenia is a permeable substrate that is kept moist regularly. The plants tolerate no waterlogging and therefore a drainage of gravel or clay granulate should be incorporated in the bottom of the vessel. Nor is calcareous soil tolerated. Therefore, it is advisable not to water the plant with calcareous tap water, but rainwater.

The ideal substrate is a slightly acidic soil with a pH between 5 and 6. Garden soil can be mixed with sand, compost or horn shavings.

In short:

  • permeable
  • lime-free
  • damp
  • slightly sour

❽ Rootballs should be completely covered with soil

The planter should ensure a good drainage for the irrigation water. Likewise, the right size is important. At least one to two centimeters should remain between pot edge and root ball so that the plant can expand and grow well. The gardenia should already be planted in moist soil. Between the edge of the planter and the upper layer of soil should remain about two inches of space. Then the plant can be better watered.

Gardenias in the summer quarter

The tropical summer may also be spent outdoors in our latitudes. Since the time span is quite short, only the planter should be put outdoors. A sheltered and partially shaded location near walls or house walls is ideal.

If you still want to plant the plant, first select a suitable location. The planting hole should be raised much larger and deeper than the root ball. The plant is used carefully to protect the roots. The root ball is completely covered with soil. After planting the gardenia is well-poured.

" Tip: If the temperatures fall below 15 degrees at night for a longer period of time, the gardenia is to be brought back to the room.
