I had three maples in the garden in my last home and they had lovely (non-green) coloured leaves on them there. I have now replanted them in my new home and all I get now is just green leaves.
Why don't they have the colour they used to have?

1How long since you replanted them? Any chance of a photograph or two? – Bamboo May 28 '17 at 15:37

1What time of year was it when you moved them? How old are these trees, how large? Are these Japanese Maples? – stormy May 28 '17 at 17:05

1Japanese maples can have gorgeous reds and purple leaves both spring with the new growth and fall. During the summer they are green. – stormy May 28 '17 at 17:08

There is an article on the net describing the causes of similar behaving of maple color.
It basically says that japanese maples may become more 'green' if:
- there is environmental impact
- there is not enough light
- there Is some growth directly from rootstock
- the tree is under stress
Seattle Japanese Garden also offers a very good article 'Gardeners' Talk: Autumn Colors and Japanese Maples'on maple autumn colors. Key point:
The brilliance of color is thought to be most affected by temperature, light, and soil moisture, not just fall but all through the growing season. It is suggested that an ideal combination would be a wet warm spring, a summer that is not too dry, and an autumn filled with dry days and cool nights.
