We recently had extensive landscaping done and we included the Red Prince Weigela. It has been very hot here in eastern PA. so we have been watering every day. The plants do get full sun. We were wondering if we might be over watering them. They look like they are turning brown at the bases. Should we water more often, or less often? Help, I don't want to lose them.
It is possible that there are air pockets in the soil that are affecting the roots. I would step firmly on the root balls to help collapse any air pockets. Flood the area with water to help fill them in. Up its watering as well. It may also have a fungus disease, so I would treat the plant with a fungicide.
