port erin,
Isle of Man 
Anchorman. I recently visited a garden centre and was shocked at the price of griselinia. In a year or two I am planning on needing a large number of these, so I looked on the net, and found your pot in a pot method of growing these from cuttings. I know it may well be late in the year, but have tried it anyway. I have never done any gardening of any nature in my life, so don't have high hopes of a high success,(if any), rate, but am keen to know what the next step will be, be it now or in the spring, which is when I intend to have another go,whether these are successful or not. I have followed the steps mentioned up to the planting of the cuttings. What I would like to know is,
when, or how will I know if the cuttings have rooted?
do I fill the middle of the pot with compost alone?
at what stage would I move them to individual pots?
what would the contents of the pots consist of?
In the garden centres I've visited, griselinia seem to be in 6" pots until they are about 2'-0" tall, then transferred to a 12" pot. Is this what you would recommend, and what would the contents of the 12" pot consist of?
I know there are a lot of questions, but as I stated earlier, I am a complete novice, so answers to these questions, and any other advice you can offer would be greatly appreciated,
Thanks,
Billybushmann.

Griselinia are really easy to root. At this time of year they may not root till spring but as long as the soil is damp and not frozen then I think the odds are good. As Ken has said above they are easy peasy to root. I do not even use hormone powder - an old windowbox and a sheltered spot and that is it.

One way to know if your cuttings have rooted is to use clear plastic containers. You can use something like those clear plastic beakers that most offices have by the water cooler and are just thrown away, the bottoms of clear coke bottles, Chinese takeaway containers, etc.
Just make a few holes in the bottom of the container, plant your cuttings around the sides of the container and you will be able to see any viable roots that develop.

Garden centres tend to sell trees as individual plants in pots, so they are expensive. Do you have tree nurseries on the IoM? If so they would be a much cheaper option for a hedge, otherwise it might be worth looking at hedging suppliers on the internet.

The clear pots/container is a good idea! Must use that.

Soft wood cutting will take very easy just Take cuttings at least 1 ft in length. Make sure you remember what end to stick in the ground . Put some rooting powder on them if you wish, then wait - they are one of the easiest to grow -- Ken
