| I'm not sure about the timing of your planting. Cold temperatures strongly induce flowering in these plants. I'm not even sure that removal of the flower stalk could have prevented this process. Once this plant flowers heavily and goes to seed, it will no longer devote energy to bud (sprout) development. Seems like these plants should be planted in the late summer for fall harvest or in the early spring for summer harvest. |
