Hi seikomom,

A.'Mend' loses its pink margins with lower light. Mine stays pink-margined with morning sun, even through winter - I also grow mine outdoors in the garden. Some prefer a green and white specimen, and grow it healthily in semi-shade. I don't think dryness will affect its colour as much as the light factor.

Cheers,
Kerry

Big Thanks,Kerry...I'll ease it into more light starting tomorrow..

Seikomon, the water from your Koi pond might also have to do with it. Depending on how effective the bio-filter of your pond is operating, there might be high levels of ammonia, nitrites and nitrates in the water, which are excellent plant nutrition! I have not much experience on how Mend reacts to nutrition, but some other broms will loose some colour when they get such a nutritious drink very often.
