The new stems will stretch throughout the cold season and in ideal conditionswill bloombetween Christmas and March. If the new stems have not formed spontaneously, it is possible to subject the plant to thermal shock in order to facilitate its appearance.

Why doesn't the orchid bloom?
The orchid may not bloom due to poor management of the plant during the summer.
An excess of light and sun during the summer can compromise the formation of the floral organs, so the orchid may not bloom in the following season. Due to an excess of light and summer sun, the orchid could dofew flowers, produce small flowers or even not bloom at all.
In summer, most of the orchids should be kept indoors (especially Cattleya and Dendrobium). The only orchids to take outdoors during the summer are the less demanding species: the Cymbidium orchid and Phalaenopsis. These species can be grown outdoors during the summer months but only placed in partial shade, where the sunlight is filtered by a sunshade, a reed bed or the canopy of bare trees (except for pines or other coniferous trees that produce resins. harmful to orchid foliage). In the warmer months, it is advisable to always choose shady positions and shelter the orchids with trellises, nets, awnings…. As stated, an excess of sunshine might not make the orchid bloom!
Leaves as an indicator of your orchid's health
Leaves are a useful indicator of your orchid's health: shriveled leaves are an indication of water shortage, so you will need to increase the frequency or volume of water used when watering your orchid. On the contrary, if the leaves tend to turn yellow you may have exceeded with the water.
The orchid is sensitive to cold shocks that can cause a sudden "sagging" of flowers and leaves.
An indicator of too low light or too low humidity is instead constituted by the fall of the buds before they can open.

Thereorchid fertilizationit must be carried out carefully and systematically. Arm yourself with a calendar and fertilize as follows:

That is to say, from October to March, the orchid should be fertilized every 10-15 days.
- During flowering, decrease or completely stop fertilizing.
- Throughout the summer, 2 fertilizations are enough to be administered in June and late August.
Forfertilize the orchidchoose a specific liquid fertilizer.
