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.
