Here is my orchid diary blog where tips will be available and regular posts about my growing regime, so basically a real inside look on how I do things and what I am doing. The good and the bad, hopefully mainly good!

Dividing and potting Orchids.

It is the time of year when dividing and re potting of orchids is best done, orchids are starting to really get going with new growths hopefully a plenty! Personally, I would only divide an orchid if it is becoming untidy with maybe bare areas of growth, or it is becoming that big that dividing is the only option.

In dividing, I may only mean to remove parts of the orchid, which is very easily done, especially plants like Masdevallia which form good sized clumps with lots of growths. So this would only involve pulling away a good sized piece or pieces with say at least 5 growths or more. These pieces then only need potting up and should grow on with the same care as the mother plants.

Fully dividing an orchid is also easy as long as it is a good size, don’t divide a small plant or take small divisions, it is best to divide in to divisions no less than 5 growths. You could divide in to less but these small divisions will take longer to mature and may struggle to really make it. Some plants just by looking at them you can see where they can be divided, sympodial orchids are one of these as they creep or branch and sometimes you get two separate creeping rhizomes. Cattleya are one orchid that often do this, you could just cut through the rhizome and pot up or you could cut through the rhizome whilst it is still in its pot and let the then two plants develop in the pot for a while before removing them and potting up individually.

Some orchids just break up in to nice sized pieces once removed from the pot and given a little encouragement, Masdevallia’s often do this.

Cymbidiums are best divided with at least 3 good bulbs or more, any old bare bulbs can be saved and potted up where they will hopefully develop a growth which will grow in to a bulb and the growth cycle continues!

Phalaenopsis would need to be large plants with lots of growths to be able to split, this I haven’t seen often! But they sometimes produce baby orchids known as Keiki’s along a flower spike. Once the keiki has produced good roots it can be teased away from mum and individually potted up!.

As will all culture, good hygiene is best adopted, so after each cut, clean and sterilize the utensils.
