    It must have been something I did wrong. Less than 25% germinated.

    Poor Germination

    First batch of seeds never germinated. Out of the 2nd batch with 3 seeds per each section of 12 sections, only 4 made it. Finally transplanted outside when they seemed to be struggling under the plant lights. Still struggling. Give them sips in early morning and at dusk and have under a little coffee filter cover so the sun won't burn them up. Grew woad in Virginia Beach with no problems.
