  1. Heat-loving flowers that grow in the tropics, at hot temperatures, sometimes drought. For them, the optimal temperature during the day will range from 28 to 30 °, at night the temperature reaches from 16 to 19 °. The daily temperature difference should be no higher than 5 °.
  2. Flowers that require and love moderate temperatures. For example, this is a tiger oncidium. For them, the optimal daily temperature in summer should reach no more than 23 °. In winter, it can be slightly lower – about 13-15 ° heat.
  3. Views that love the cold. They usually grow in mountainous, shady forests where there is high humidity. The temperature range in which they feel comfortable is wide – from 15 to 25 °. However, despite this, it is important for this group of orchids that the daily temperature difference does not exceed 2-3 °.

Orchids that grow in apartments are hybrid varieties.They feel good in a wide temperature range – from 15 to 26 °. If the temperature is higher, the plant stops the process of root growth, which means that the oncidium will not bloom. For good growth and a favorable state, the desired temperature should be maintained, while not allowing its sharp jump or drop. It is in such cases that you can transplant without causing any damage to it.

Watering and flowering

Watering rules:

At the same time, you should not wait for the soil to be too dry and begin to crack, as this also has a detrimental effect on the growth and flowering of the plant.
  2. You should not adhere to a specific watering schedule for oncidium, because the speed of soil drying depends on many factors . If the street is summer, then the soil will dry out many times faster. In winter, this process takes a little longer.
  3. When forming a pseudobulb, you need to abruptly cancel watering, only in this case the orchid will bloom. Somewhere in about 21-28 days from a new growing pseudobulb a flower stalk should go. When you are convinced that this is it – resume the regular watering process.

When the flower has already faded, the watering procedure should be slightly reduced, since the plant does not need too much moisture for this period . With proper watering, oncidium blooms approximately every 9-12 months, in some varieties a little more often.

Fertilizing and fertilizing

Fertilizing is required only in growth period of young shoots. During the formation of pseudobulbs no additional feeding is required.When the flower stalk begins to develop and the flowering process begins, top dressing should be resumed again.

Propagation of oncidium

At home, the reproduction process is carried out only by the vegetative method. It is worthwhile to start dividing the curtain only when more than 6 pseudobulbs are tied to the flower. Only in this case the divisions will be viable.

The division procedure is carried out with a sharp knife. For this, an underground stem is incised. After this, the place where the cut was made, it is necessary to sprinkle with charcoal. It is important to observe one more prerequisite: during the process of dividing the land must be necessarily dry. Also, after the procedure, the plant can not be watered for about 10 days, which will allow the wound to dry.

Reproduction, you can do it with the help of a baby – a process that has its own root system. However, this phenomenon is rarely found in practice, and if you have a offspring on an orchid, this is more an exception than a rule.
