Your Cymbidium plants will flower during the cooler months. When they have lost their blooms, the spikes should be cut off and the plant inspected to see if it needs repotting or dividing. If it is a fairly small plant, but is filling its pot, it can simply be knocked gently until it slides out of its pot. Replace it in a bigger pot, making allowances for about two years growth. Larger chunks of potting medium, such as pine bark, should be placed in the base of the new pot , the plant is then put in and potting medium tipped in to fill in the sides. Press down firmly and water well.
