BellinaThere’s a certain kind of plant that teaches you patience whether you signed up for the lesson or not. Mine is a Bulbophyllum (cruentum × phalaenopsis), and after three and a half years in my living room, it has finally given me its first bloom.
Where it came from
I picked this one up at the Southern Ontario Orchid Society show and sale. I filmed the haul and posted it on February 12, 2023, so I know exactly how long this plant has been under my care. If you want to see it as a fresh, unassuming little thing before it took over a corner of my living room, the original video is here: https://youtu.be/K3z7MOpV4MI
At the time I bought it mostly for the foliage. Big leaf Bulbophyllums have that thick, leathery, almost prehistoric look, and this cross delivers on that. I told myself the flowers would come eventually. I did not expect “eventually” to mean three years.
The conditions it’s actually growing in
I want to be honest about this, because so much orchid content online describes greenhouse conditions that most of us can’t replicate. This plant lives in a regular Ontario condo living room. Here’s what that really looks like.
Light. Southwest exposure, which sounds intense, and the room genuinely is very bright. But the plant sits where the light is diffused before it reaches the leaves, so what it’s actually receiving is bright shade rather than direct sun. That seems to be exactly what this cross wants. Big leaf Bulbos scorch easily in direct light, and the deep green on this one tells me it’s comfortable.
Winter. Once the heat comes on, my humidity drops. That’s just condo life in Ontario. I don’t run a humidifier for this plant specifically, and it has tolerated the dry stretch without dropping leaves or shrivelling.
Summer. This is where I think the plant does most of its real growing. I only run the AC during extreme heat and heat waves, so my apartment sits around 24 to 27°C during the day with high natural humidity. Warm and humid is Bulbophyllum weather. Those months are when I see new growth pushing along the rhizome.
The watering trick that I think actually mattered
I’ll be upfront: I water this plant when I remember. I am not running a schedule. But there’s one thing I do consistently, and I suspect it’s the reason this plant thrived instead of merely surviving.
I always leave a little water sitting in the bottom of the pot.
Bulbophyllums are water lovers. In habitat many of them grow in consistently moist, humid conditions and they don’t have the drought tolerance that, say, a Cattleya does. Their pseudobulbs are small relative to those big leaves, so they don’t store much of a buffer. Letting them dry out completely is how you get shrivelled bulbs and stalled growth.
That shallow reservoir in the bottom of the pot means that even when I forget for a few days, the roots and the media stay damp. It’s a low effort insurance policy for a forgetful waterer. I wouldn’t do this with most orchids in my collection, but for this genus it has worked beautifully.
If you try it, a few notes: use a pot with drainage so the water level stays shallow and doesn’t submerge the rhizome, keep air moving in the room, and refresh the water regularly rather than letting the same water sit and go stagnant.
Feeding: are Bulbophyllums heavy feeders?
This is the question I get asked and the one I’ve asked myself. The short answer is no, not particularly. Bulbophyllums are steady, moderate feeders rather than hungry ones. What they respond to is consistency, not concentration. Regular light feeding through the active growing season will build a bigger plant faster than occasional heavy doses, and heavy doses on an epiphyte with fine roots is how you get salt burn and tip die back.
I’ve been using Crystal Star Nursery Botanical Booster, a water soluble 21-5-20 with micronutrients. The label gives two rates: ½ tsp in 4 L for orchids and sensitive plants, or 1 tsp in 4 L for general use, applied every other watering during active growth.
I go weaker than even the orchid rate. I dilute all my fertilizer well below label strength across my whole collection. It’s the “weakly, weekly” philosophy, and with orchids especially I’d rather underfeed slightly than risk burning roots I can’t easily inspect. This plant has gotten that weak solution during its active summer growth and clearly hasn’t felt deprived.
The high nitrogen ratio in a 21-5-20 supports foliage and new growth, which is what a big leaf Bulbo spends most of its energy on. That’s fine. I’ve never believed in switching to a “bloom booster” to force flowers. This plant bloomed because it finally had the size and maturity to afford it, not because I fed it something special.
Why it took three years
That’s the real answer, and it’s not satisfying if you’re waiting on your own plant. Big leaf Bulbophyllums bloom when the plant has bulked up enough to support flowering. There’s no trick and no product that shortcuts it. You give them warmth, moisture, gentle light, light steady feeding, and then you wait through several seasons where nothing visibly happens and you start to wonder if you’re doing it wrong.
You’re probably not doing it wrong. The rhizome is creeping, the leaves are getting bigger, the plant is quietly building capacity. And then one day you’re fussing over something else nearby and you notice a bud tucked low at the base.
Three and a half years. First bloom. I’m a little emotional about a flower.
One warning
That Bulbophyllum parentage. If you know, you know. This genus is famous for fragrances that are, let’s say, aggressively not floral, and Bulbophyllum phalaenopsis is one of the worst offenders. I’m bracing myself, and if it turns out to be as bad as advertised, this plant may be spending its flowering period on the balcony.
Worth it either way.
