Amaranthus tricolour colour

Posted by Glenn_50 New Plymouth NZ (My Page) on

I have planted a lot (thousands) of Amaranthus tricolour perfecta to harvest the leaves for including in commercial salads. The early sown ones are growing well but only about 1% are bright colours, the rest are rather dull.
The crop sown a month later from the same seed is a blaze of vibrant colours...every one.
I have cut back the dull ones in the hope that new growth may develope brighter colours. I was wondering whether increased potash might help. These are all in containers in a glasshouse.
Any ideas would be appreciated.

I have noticed the same thing, sometimes the plants all are dark with reds and other times they almost start out yellows and reds. I wish I had an answer for you, but since your planting times differed by a month or so, perhaps length of daylight made a difference.

Just a thought.
