Question
Hiya i wonder if you could help,

I was bought a mini orchid last year and it only had a couple of flowers on it which fell off within a week i repotted it and this year it has atleast 8 flowers out three still to come and another stem coing ou tthe side with more buds.

I would like to take a cutting from this orchid so i can have another one for my mum except im not very experienced with this.

Also there are some roots above the soil does this mean it needs a new pot?

Any help would be great. thanks

Ruth, I will assume from your description that you have a minidendrobium orchid. Congratulations that you have done so well with it.  Minidendrbiums have upright growths called canes from which the flowers emerge. You cannot take cuttings as you might from some houseplant.  However, if the plant has enough canes, you could unpoy it and simply pull off a group of canes-- roots and all-- from the main plant and then repot both resulting plants.  To do this, howver, you should have at least 8 canes with at least 4 canes going to each plant.  If the plant doesn't have at least 8 canes, you will need to wait until more canes grow the plant larger before dividing it.  Minidendrobiums sometimes form keikis, which are plants that develop at a node on a cane.  A keiki can become a complete plant growing on the mother plant.  These can be separated from the cane on which they are growing and be potted separately.  Most orchids have aerial roots.  When you decide to repot, you may be able  to tuck some of these aerial roots in the new potting mix used to repot the plant.  You may want a slightly deeper pot for repotting so some of these aerial roots can more easily be place into the pot and potting mix.  Bear in mind that if my assumption about this orchid being a minidendrobium may be in error.  Part of my assumption is based upon the amount of mass marketing of these orchids in places like supermarkets, which make them quite common.
