This plant is nearly a noxious weed in my yard and vegetable garden.
Birds deposit seeds constantly, and as a result I'm constantly pulling
up poke shoots, but MANY make it to flowering and some to fruiting stage
with NO HELP from me or anything else.
SOOO, my first GUESS is that your soil mix is too good! Poke grows very
well in nearly 100% clay, so I'd back way off on the soil lighteners and
go with an overwhelmling proportion of top soil.
My second guess is that it's not getting enough light. Poke thrives in
direct sunlight and when I find it in various degrees of shade, the
plants are definitely more spindly. Many greenhouses don't have
anything near the equivalent of direct sunlight.
My final guess is that it's getting too much water. Soil mixes like you
mention and greenhouses usually equal LOTS of water spray. So maybe put
it outside and let rains do their thing.
BTW, for what reason are you growing it?
