Sprayed four germanium hanging baskets. All dead! First time I used on these type flowers. Always sprayed hibiscus in past. No problem. This year killed my plant. What is happening?

Hi Nancy- Applying chemicals in high temperatures or strong sunlight can increase the risk of damage. Sevin is generally safe for many ornamentals, however, some plant species are more sensitive to certain chemicals than others. We recommend to either spray after dark or wait for cooler weather (below 80 degrees). Thank you.
