It is possible that the weigela and forsythia have frozen if they were exposed to extremely low temperatures. Both of these plants are susceptible to frost damage, especially if they have not been properly protected during cold weather. Signs of freezing may include wilting, browning of leaves, and damage to the stems. It is important to monitor the plants closely and provide appropriate care to help them recover from any potential freezing. **

Copper in the soil can be toxic to plants, including forsythia. To save your forsythia, you can try to reduce the amount of copper in the soil by adding organic matter such as compost or peat moss to help bind the copper and make it less available to the plant. You can also try planting the forsythia in a raised bed with fresh soil to avoid the copper-contaminated soil. Additionally, you can consider using chelated iron supplements to help counteract the effects of copper toxicity on the forsythia. **
