    Default Tolumnia orchid Care?

    I bought one of these cute & colorful orchids at the Orchid Show here this weekend.
    It is in a tiny clay pot (1.5 inches, I think) with small bark media. 4 fans, and loads of healthy-looking air roots.

    What I think I know is that they want to be watered often, but to drain freely & dry out. The media does dry out quickly. I am watering it every other day...should that be more or less often?

    Also, the oldest fan is in the center of the pot, and the newest right up against/on the edge. When it finishes blooming, should I repot in a larger pot? Or put it back in this pot, with the oldest fan against the pot, and the newest in the middle...which should give it room to grow maybe 2 more fans? I am thinking that this probably does best either mounted or if in pots, in tiny ones??

    Advice?

    Beautiful buys, Kathi. Tolumnias love to have good air circulation around the roots so that they can dry out fast. In my experience mounting seems to be the best option.

    Thanks, Yew Sung. I am thinking I will let it summer outside with the majority of my orchids, and if so, it ill get lots of heat & lots of air...I'm afraid a mount might dry out too fast then? I may keep it as it is for a bit, and watch to see how long it takes to dry out before I decide...

    Some of my Tolumnias are mounted on 3 x 1 1/2 inch coffee sticks, others in small net baskets with a mixture of hard wood charcoal and coconut fiber. The main thing is to have them drain well and be dry before nightfall and that they have good air circulation at all times. I hand dip the entire plant in a weak worm manure mixture of organic tea on a weekly basis. Watch for any signs of scale and aphids. Fungus is also a major threat and more so when there are experiencing still windless nights with high humidity. Be very careful about using some agro-chemicals and if necessary, keep doses at a minimum. Watch the root tip growth since they communicate their happiness and welfare by their development. I have them growing under my Cattleya conditions which is fairly sunny without the midday sunlight that can cause them to be overheated. At the moment they are all in flower and giving quite a show.

    Kathi, I love those crazy roots! I'm interested in whether you should enlarge the pot or not - I'll keep an eye on this thread.

    I would suggest keeping to small containers and go to a small plastic net pot. In the wild, the original Tolumnias grow with a mass of 'rasta' roots and like a loose relationship with it's host tree branch or twigs.

    Thanks Peter. I just got some small net pots, and think I will do just that. I also have 2 more Tolumnias on the way. These guys are just too cute!

    In South Florida I noticed that the Tolumnia growers were using the plastic net pots and a mixture of some fine charcoal and course treefern fiber. They sort of stacked the treefern upright in the pots with the charcoal bits stuffer in among the stiff upright course fibers. This also helps to position and hold the plant loosely with the growing edge on the middle.
