    Default Maxillaria which will not flower

    I have 2 types of Maxillarias - one I think is a Tenuifolia (right) but the other one is unknown to me and I haven't managed to get it to bloom (left).

    I bought the "unknown" one 2 years ago and it looked like this -

    So as you can see, it has grown a lot of pseudobulbs but just refuses to produce any flowers. It has the same conditions as the Tenuifolia which has rebloomed this year but there is no sign of any blooms from the other one.

    Does anyone have any ideas about how to get it to bloom? Would appreciate any advice!

    My advice would be to try increasing the light level. It obviously grows well for you

    And increase the potash and phosphate N:P:K =67 usually will facilitate buds formation also keep him dry.

    Maybe also give it a drop in temperature at night.

    Wow! After more then 40 years of orchid growing, it still amazes me how much variation there is in culture that works for people. My maxi's are grown in baskets, hung up near vandas (I really don't get quite enough light for them, but it's the best I can do), which agrees with Ron, but they are getting K-Lite fertilizer regularly (have been for 2.5 years now, and it's a 12-1-1, which totally opposite of Zainal's advice, and any temperature variation they may see is a whim of nature, as I only control the nighttime minimum in the greenhouse.

    One thing that was not mentioned was the potential for being overfed, especially nitrogen.

    Thanks for the suggestions, I will try giving it more light (although it does get quite a lot already) but now I'm wondering if indeed I am over feeding it and that's why it grows abundantly but doesn't produce flowers. Ray, the difference in what works maybe due to the different growing environments, perhaps? Mine are on a covered balcony. What puzzles me is why the tenuifolia has bloomed but not the other one even though they have the same environment, water and feeding. Zainal, when you said "keep him dry" did you mean not so much water? I was under the impression that maxilla rials like more water?

    Not every plant of the same species, let alone the same genus, will have exactly the same optimal growth requirements. Most species have one or more ranges of territory in which they grow, and the conditions in each, or even within each can vary.

    Another example of "different strokes for different folks": the nest Max tenuifolia I have ever grown was in semi-hydroponics, getting constant moisture.

    I have few Maxillaria species morning I spraying the water by noon the medium always dried and with short dry spell usually 2 to 3 weeks will trigger buds formation especially M.rubioi, rufescens and setigera.

    Ray and Zainal - many thanks to you both for your observations and suggestions, even if they sound contradictory, as they give me lots more ideas about what to try! This is what makes orchids so much fun - the challenge to figure out what works for each one...

    Pulled it out of the pot I had it in and roots look good but it was quite damp in there so I'm thinking that I should try the "drier" approach and have put it in a slatted basket. I've heard many people talk about theirs hanging up and so I've hung it up where it will also hopefully get more light as well... the only thing I can't control is the very wet and rainy weather we are having at the moment!
