You don't need a cold frame to root cuttings, but perennials typically can be divided. Here is more:

My cuttings are rooted with approximately 4 leaves on each cutting I have about 20 small pots
You can treat them like houseplants inside over the winter. Your cuttings are rooted but this article may help:

any additional shoots. only the single stem that grows every year albeit with some beautiful blooms. How does one propagate thes e plants? Three plants have been in the ground for some 10 years the others about three years. 21 plants in all.
This is best done by dividing the bulbs. Here are some articles that will help:

Thanks very much. I was a bit apprehensive about digging up beautifully flowering lilies in case I killed them but - no pain - no gain

I don't know if this applies to all fruit saplings, but I have a few that I have grown from pips who's leaves are starting to curl up and I'm not sure why. They are all kept in a glass greenhouse whose temperature fluctuates depending on the weather, and drops to approximately 8 degrees in the evening. Can you please advise what I should do? Kind regards David
Citrus leaves will curl for just about any little thing that happens. They are typically quite hardy, but they will get destroyed by spider mites. I see the signs. I battle these all year with my indoor citrus trees. I would treat with neem oil, or the active chemical in it called Azadirachtin.
To be sure, I would check the pH and nutrient levels in the soil after correcting the issue.

It is growing in a large pot and is doing well.
You can, but I am not aware of a plant with that name. Maybe this is a Pieris? I can give you general methods for taking cuttings, though.
The process is the same, whether these are indoor plants or outdoor. This article will help:
