Re: Cultivation of Dracunculus vulgaris

My plants are growing in a sunny place. They wake up in autumn, but they start to put up the leaves next spring. In my garden the soil is very heavy clay and tubers often rotted in the early spring. Now I add some ceramic granulate as the drainage and peat to make the soil lighter. I water and fertilize them only when the are in leaf and start to bloom. Watering dormant tubers is a risk of rotting.
 
Best,

All of the ones Ive grown no matter where Ive gotten them, begin sprout roots in the fall, grow leaves, flower in the spring then die back when it gets warm. They dont like any sun or heat it seems.

When I lived in Los Angeles, I just placed some tubers of D. vulgaris in the ground and forgot about them until they sprouted and bloomed.
 
Here in North Texas, the circumstances are a little different (eg. temperatures, humidity, etc.).  I tried growing 7 tubers in containers.  Four sprouted, two did not sprout - but still look viable, and one rotted. 
 
The four that sprouted did so in April - May, looked terrible, and were down within 6 -8 weeks or so.  When do they ordinarily sprout in the Northern Hemisphere?  How long do the ordinarily grow before going dormant again.
 
Is there a particular soil acidity/alkalinity requirement for this species? 
 
I had them in partial shade (early morning only).  Do they require more shade or more sun?
 
I watered them with a weak plant food when I thought they needed it (more often in warmer weather).  Should they be allowed to dry out or should the soil remain moist?
 
Thanks in advance for your suggestions.
