They prefer very bright locations, but not directly exposed to sunlight in the hottest hours of the day, in the warm months of the year can be placed outside, in a sheltered but airy place, where the plant can enjoy plenty of light and a few hours of direct sunlight in the late afternoon.
The caladenias fear the cold, with the lowering of temperatures the leaves turn yellow and dry, it is advisable to keep the pot in place with temperatures above zero, to prevent the plant frost; it is advisable to place the pot of Caladenia outside the beginning of spring, because the cold and rain stimulate the growth of the new leaf and the subsequent flowering.

During the vegetative period, the caladenias need abundant quantities of water, we suggest always keeping the soil slightly moist; when the leaves begin to dry up, suspend watering, letting the plant go into vegetative rest.
During the warmer periods, it is advisable to spray the leaves with demineralised water, in order to guarantee the correct level of humidity.
From March to September, add orchid fertiliser to the water of your watering every 15-20 days.
These orchids need a loose, sandy and well-drained soil; use good balanced soil, mixed with sand and leaf mould, taking care to place expanded clay or perlite on the bottom of the pot to increase drainage, as the orchids can not stand waterlogging that can quickly cause root rot.
The plant should be repotted when the roots have occupied the entire pot and, to avoid damaging the roots, which are rather fragile, it is advisable to wet the soil before proceeding with the operation.
The reproduction of the Caladenia takes place by division of the rhizomes and is practiced in spring, at the end of the winter, before the plant wakes up from the rest of the cold months; the new plants are immediately repotted in a single container and cultivated like the other plants.
Caladenia: Pests and diseases
These orchids do not fear much the attack of pests, it is not uncommon for them to be affected by root rot, which occurs easily if the soil is not sufficiently draining and stagnant water forms.
These plants can also be affected by the cochineal that is deposited on the leaves, to eliminate the problem you can intervene manually with the use of a cotton ball or a cloth with alcohol to pass on the leaves to remove the parasites. If possible avoid the use of chemicals that could harm the health of the plant.
