how to grow cattleya orchids

Once upon a time the Cattleya orchid was THE corsage orchid. It’s easy to see why. Large, long-lasting, colorful blooms with grace this orchid. There is something right and reassuring about this timeless orchid. It’s your turn to grow this classic favorite!

My Cattleya Journey

Despite my hesitation, a couple of years ago I purchased two mini Cattleyas. Here’s why I was hesitant: I didn’t know if I could provide enough light and humidity. I’m not a greenhouse grower, and I live in the desert. I figure, whatever I can grow, anyone can grow. In the end, I found Cattleyas extremely rewarding. Here’s how I got around their high light and moderately high humidity requirements. 

Follow these steps and discover how easy it is to grow Cattleya orchids

 

Light

First off, Cattleyas are notorious for their high light requirements. In fact, among orchid growers, Cattleya light has become a standard. When I first brought home my Cattleyas I set them close to the window where they could receive the most light. To thank me for my efforts, their blooms and buds promptly died and fell off. They didn’t like the transition from the greenhouse to the window sill. But, they started growing roots like crazy.

I knew it was time to pot them. I bought a couple of  orchid pots: black and cobalt blue. Whereupon the summer heat sizzled their roots. The dark color of the pots only absorbed more heat, exacerbating the problem. That’s when I high-jacked my husband’s grow lights.

GROW LIGHTS I USE

 

Growing under lights, the roots improved dramatically. My Cattleyas had beautiful green-tipped roots galore. The florescent lights don’t put off too much heat and the orchids seemed much happier, except….

Humidity

…except that the leaves were slightly on the shriveled side. They needed more humidity. Catttleyas require between 40-70% humidity. Living in the desert, getting around 50% is my target goal–with a humidifier.

All I had to do was to move my humidifier closer to orchids. I didn’t turn the humidifier up. I just moved it. The leaves improved. Not as quickly as the roots, but still I am happy with the way my Cattleyas’ leave now look: thick and fleshy, no wrinkles.

That’s all well and good, but that year I didn’t get a single flower. Back I went to the drawing board.

THE HUMIDIFIER I USE

Lighting Adjustments=Flowers

As you may know, light is the #1 reason orchids don’t bloom. This last winter I adjusted the light timer correlate with the seasons. This is one of those do-as-I-say-not-as-I-so moments. I know, I should have done it long ago, but it’s such a PAIN.

Being desperate for my Cattleyas to flower, I adjusted the timer for the lights. What do you know, but it made all the difference. This past winter I set the timer so the lights turned on at 7 am and off at 6 pm. Now that it’s getting lighter, I’ll change the timer back the summer schedule of turning on at 5 am and off at 8 pm. My flowers still look fresh, and they’ve been in bloom for a couple of months.

To make things easier so I wasn’t so reluctant to adjust the timer, I got a new one. This timer is much easier to use.

THE TIMER I USE

Buying Guide

For best results, don’t buy just any Cattleya. There are a few things to consider:

Size

Some Cattleyas can grow to be quite large. Ask the seller how large the orchid will grow and make sure you have enough space. With a growing orchid collection and limited space, I am sticking with minis. But don’t hold me to that!

Hybrids

Cattleyas have been popular for a long time. The Victorians adored them. Hybridization has resulted in stellar cultivars, and some unreliable ones as well. Buy a proven winner. If you’re purchasing from a reliable vendor, they can tell you how reliably the hybrid will bloom.

Cattleya Recommendations

Here are a couple of Cattleya recommendations. These are varieties good choices for beginner Cattleya growers.

Cattleya skinneri

Cattleya, skinneri

 

Cattleya intermedia

In a Nutshell

Here’s how I made Cattleyas work for me. First, I’m growing them under lights. Second, I’ve placed them near my humidifier. Third, I adjusted the automatic timer to reflect the season. Result: green-tipped roots, full, fleshy leaves and flowers. With a few modifications, the most significant being lights. I firmly believe you can grow Cattleys indoors. 

Remember to buy a proven cultivar, one that’s the right size for your space.

    My dad buys my mom an orchid for Mother’s Day every year, and I’m pretty sure it’s a Cattleya! I definitely want one in my home now! 🙂

    I use essential oil diffusers in the main rooms of my home. Do you think this would be enough humidity? I wouldn’t use the oils near the orchid for fear of damaging them. Thanks! 🙂

      Chantile,
      It’s so great to hear from you! Do you know what the the humidity levels are in your home? Cattleyas do best with at least 50% humidity. I know my levels aren’t that high, but I do keep mine right next to my humidifier.

    I love the fantastic fragrance mine put forth. That is why I bought it 9 years ago. Quite surpringly, I got my first blooms ever in February this year. I do not use lights or a humidifier. I soak it once or twice a week depending and I feed it at every watering.

      Thanks for sharing!

    I have 2 cattleyas but I’m enduring the pain of not having them bloom.
    The plant I have now forms a bud, but dies before blooming.
    Please, advise…Jacques

      Jaques,
      This tragic situation has a name: bud blast. When a bud forms, but withers and dies before blooming it is usually the result of environmental changes. The fact that your orchid is forming buds is a good sign. Now you need to determine which environmental changes you can make so that the buds will open and you’ll get flowers.
