|I recently (after the ground had warmed up to about 65 degreed) about ten dahlias into the ground. However, we recently had a 2 or 3 day stretch of mild frost(about 30 to 3 degrees) I planted the tubers in a raised bed surronded by red bricks(that warm the surronding soil by as much as five degrees) and placed a protective mulch over the ground to keep the plants save should frost occur. My question is, will the plants grow or will they shrivel and die?
|I think they will be fine. If there is frost after they have emerged from the soil then you might want to cover the tops with an overturned flower pot or a cardboard box, but underground they are well insulated. Enjoy your dahlias.|
