Everything you need to know as a beginner to grow Cattleya Orchids
Cattleya orchids, with their exotic and glamorous, often frilled flowers, have earned their place as traditional corsages for special occasions. With around 70 species primarily hailing from South and Central America, and numerous hybrids grown as houseplants, these tropical treasures offer a breath taking array of colours to choose from. In this comprehensive Grow Guide, we'll reveal all you need to know about nurturing these captivating beauties in your own home.
Where to Grow Cattleya Orchids
To set the stage for your Cattleya's success, choose a warm and bright spot, but be mindful of shielding them from direct sunlight, especially during the summer months. Aim for minimum night temperatures of 10-15ºC and create a slightly humid atmosphere, mirroring the conditions of their native rainforests. For a gentle breeze reminiscent of the tropical forest, a fan nearby can work wonders.
Planting Cattleya Orchids
Creating the perfect potting mix is key to mimic their natural growing conditions. Bark and rocks or perlite provide excellent drainage and aeration, which Cattleyas adore. You can either prepare your own mix or purchase commercially made orchid compost. When selecting a pot, opt for a size that is not significantly larger than the root ball, as Cattleyas prefer snug spaces for optimal growth.
Propagating Cattleya Orchids
The magic of Cattleyas' flower stems lies in their development from a pseudobulb that sprouts from a new bud at the base of the plant. Mature plants may have plenty of pseudobulbs, and if you count more than eight, consider dividing the thick rhizome to create two separate plants for repotting. The best time to divide is when the plant is not in bloom.
Cattleya Orchids: Problem-Solving
As with any prized plant, pests can pose a challenge. Keep an eye out for mealybugs or scale insects, which are small sap-feeders and can be tricky to spot, often lurking in crevices. Vigilant inspection is key, and if infestations are severe, removing the affected plant may be the best course of action. Alternatively, consider introducing biological controls such as ladybirds or parasitic wasps.
Caring for Cattleya Orchids
During the growing season, which spans from March to September, water your Cattleyas twice a week and feed them with orchid fertilizer every two weeks. As winter approaches, adjust your watering routine to avoid overwatering—under-watering is preferable during the dormant period. Once the flowers have bloomed, prune the new flower spike to encourage future growth. Repotting your orchid every two to three years will ensure healthy growth, especially when you observe roots wrapping around the base of the plant—a natural characteristic reminiscent of their growth on trees or rocks in the wild.
By following our Grow Guide, you'll be well on your way to cultivating stunning Cattleya orchids that are the envy of all orchid enthusiasts.
