This is the first year that I have planted brandywine.
The plants are turning purple... is this normal?

The plants need phosphorus. Fertilize them with a
"high middle number" fertilizer. Like an 8-32-16 or
something.

If you're trying to be organic, bonemeal is the
middle number organic source, but I don't know
how fast a plant can uptake it...
