I have had my bottle bush since late Sept. early Oct. last year. After the freeze the bushes began turning brown. I contacted my landscaper who came out and examined them. He advised me to cut off the brown limbs due to freeze damage. After doing so, I am still having a problem. It seems after the plant blooms the whole stem to which it is attached turns brown and looks dead. In the beginning it was only about 3 bushes out of 7. Now it is happening to all but 1. I water them regularly and make sure the green leaves are not curling. Don't want to lose all my plants! What can I do?

The frost damage can leave a plant stressed and vulnerable to disease and pests. Some damage can take weeks to appear and stop, depending on the severity. If the weather still threatens to be cold it is best to leave the damage on until the weather changes.
Examine the plants for any other signs of issues.
Watering is important but make sure the soil is well draining and that they are not too wet.
Root rot can show itself as browning and dying leaves.
