These orchids need to be grown in a very bright area, but far from the sun’s rays; they fear the cold and even in winter the temperature should remain around 15°C. While the summer temperature should not exceed 30°C.
Laelia, in nature, are plants that grow on rocky or particular surfaces, therefore they require a good exchange of air. Above all, this type of orchid needs a lot of light to grow and bloom, so it is essential to place them in environments where they can receive a lot of light, but always taking care that they do not receive direct sunlight.
Obviously, it is essential to know the exact variety in order to know what the particular cultivation requirements are, since they also have very different characteristics.

- Generally, when we think of an orchid, our imagination evokes memories of delicate plants, with very particular requirements, often with aerial roots, which should be cultivated only by real aperitifs.
In the period from March to September water abundantly and regularly, without ever soaking the substrate of cultivation, but keeping the humidity very high. In winter, reduce watering, to allow the plant to go into vegetative rest, however, try to keep the substrate always slightly moist, avoiding to let it dry too much, but checking that there is the possibility of the formation of stagnations of water, much damage is done to these plants.
From March to October, add specific fertilizer for orchids to the water of the watering every 7-10 days.
Since laelia are all epiphytes, they need a substratum made of incoherent material, such as bark, sphagnum or osmunda fibre; use a compound for orchids that is easily found on the market. Remember that this substratum degrades with time, so it should be replaced annually, to provide the plant a fertile base on which to grow. Pay attention to the repotting operation, which must be done with caution to avoid damaging the roots, which are rather thin and delicate.
To facilitate the operation, it is advisable to wet the roots of Laelia before proceeding, taking care to eliminate all the old substrate. Always choose a slightly larger pot, as the substrate must be able to dry quickly.
By the end of winter, as soon as the plants begin to vegetate again, we can proceed to the division of the heads of pseudobulbs, taking care to keep some vigorous roots for each portion done; repot immediately the new plants in single containers, utilizing the substratum indicated for the cultivation of the orchids.
Laelia: Pests and diseases
These orchids are easily attacked by cochineals, which ruin the leaves and flowers. If their presence is limited, it is advisable to intervene manually to eliminate them with the use of alcohol to rub on the leaves.
These plants can also present pathologies linked to unsuitable environmental conditions or to an excess of watering which can lead to radical rottenness.
