Hi I have a row of dahlia and one just flop over. When i touch it was all wet i don't think it was from too much water cause the rest of the row is ok and the ground is not wet. I had to cut it from the ground. Will the bulb rot? And will it start to grow again? i know that dahlia are petty strong i move the earth from the top of the bulbs and its firm so far but it just happen. What can cause this to happen. Could it be a bug? please help Anna lisa
