Cattleya loddigesii 'Blue Sky' AM/AOS

Good looking root cage

This is a picture of the roots of a Cattleya loddigesii seedling that I am re-potting. All the medium (rocks) has been removed. What is left is a pot full (but not too full) of healthy roots.

Cattleya loddigesii grows in Brazil, Argentina and Paraguay. It is fragrant, cool to warm growing and can grow in sunlight. The flowers are long lasting and blooming is in late summer.

filling the root cage with sphagnum is the first stepThis is one of five seedlings I got five years ago at a nursery going-out-of-business sale. They are finally getting some size and I am potting them in sphagnum over peanuts in clay.

This is as good a root cage as I've seen. There was almost no trimming needed. The only thing is to make sure that the sphagnum does not break the roots when it is added in the new pot. I do this by putting a generous pad of sphagnum inside the root ball.

I am optimistic about seeing flowers this year. There is great new growth and a sheath on the last pseudobulb.


  1. pictures not showing. Just a "?" placeholder

  2. Not sure what happened. Pictures are back.

  3. what kind of rocks do you use?

  4. I use white limestone because I like the look of it, but granite would do as well. Any 1-inch or less rock chunks that are handy except for lava.

    Lava is ok for some orchids, but it holds an awful lot of water, too much for any of the plants that need to dry between watering such as Catts or hard-cane Dendrobiums.
