GARDENIA CARE INDOORS. GROWING GARDENIA

Unfortunately, growing gardenia flower cannot be called simple, as it requires special technology. Gardenia fragrance is a gardenia5common topic for florists to speak of. This flower is rather capricious and demanding for care. Air temperature for gardenia plant should be not lower than 15-18 degrees but not higher than 24-25 degrees above zero. You should be the most careful in winter. Gardenia roots must not be overchilled.  To guarantee this, gardenia flower must not be put on a cold windowsill, you better put the pot on the foam plastic or take some other warming support. Don’t take gardenia augusta to the balcony in summer. Gardenia doesn’t like sharp temperature changes.
Air humidity must be high but you should sprinkle the gardenia bush very carefully especially in the period of buds initiation and blossoming. Drops at sprinkling should be very tiny and not fall onto the buds and flowers, i.e. you should sprinkle only the air around the plant, but not the plant itself. It is easier to put the house plant Gardenia Jasminoides on the pebble in the tray with water or in the damp moss (sand), but in the way that the pot doesn’t touch the water. Thus, water evaporation will create the necessary humidity around the plant but the roots won’t be wet all the time.  

Gardenia Jasminoides requires abundant watering with soft warm water but don’t forget to remove the excess moisture from the tray. You should be especially careful about watering while the plant is blossoming. Don’t let the soil be over-dried or over-wet. The soil must be always damp but never wet. If you violate this rule gardenia can lose the buds. You can also notice your gardenia leaves turning yellow – it can be of the same reason.
Gardenia care involves bright light needed for the plant to grow well. But you should remember that direct sunrays at noon influence jasmine-type gardenia too bad, it is better to shadow the plant at this period.

The plant does not need nourishing in autumn and in winter. Gardenia fertilizer is available in common florist shops.
One more fact of gardenia care is that in order to have a beautiful plant gardenia pruning should be done properly. If you want to have a thick gardenia bush you should nip the tops of young plant’s sprouts, but in case of the old gardenia plant weak sprouts must be removed after blossoming and other sprouts must be cut at the necessary length. Usually the one-third of the sprout is cut. In house conditions you can grow a stem tree of gardenia. For this side branches are cut and the top is left. When the plant reaches the necessary height you should nip the top point of growth and cut the other sprouts making a crown.

GARDENIA REPRODUCTION.

The easiest way of reproducing gardenia bush is through stem cutting. At the beginning of spring the top cuttings 8-10 cm long are cut with a sharp knife under the very node. You should leave 3-4 leaves on the top of the cutting, removing the others. After this it is desirable to plunge the cutting in the phytohormone solution for several seconds and plant it into a sand-and-peat mixture, sprinkle and cover with a film. The best temperature for rootage is 25 degrees above zero. Don’t forget to water and sprinkle and open for airing every day. After the cuttings are rooted and begin to grow they should be planted in the permanent place in the soil consisting of equal parts of peat, sod, coniferous, leaf earth and sand or the soil for azalea (roses).
Besides cutting, gardenia flower can be reproduced by seeds. The quality of gardenia seeds is crucial. Gardenia seeds bought in the shop can be old and their germinating capability can be low, but the plant itself can make you happy with the boll of seeds. Gardenia seeds are better to be sowed in the soil (the same as for cuttings) in spring. The layer of soil above the seeds must be 3-5 mm. the soil after the seeds are sowed should be pressed a bit and damped. The seeds grow in a greenhouse or covered with a film at the temperature of 25 degrees, with regular damping of the soil and sprinkling in about a month, but the plant grown from the seeds will blossom not before 2 years.
