Please help me! This is the second summer, that I have lost my mandevilla to southern wilt (Atleast that's what I've identified it as)

They have been perfect, healthy, and growing like weeds since May. And then, out of nowhere, I noticed a few blooms start to droop. Then the browning starts, and then they're completely wilted and dead. I thought last year, it was just a fluke. Now I know it's something I've done.

They are in cement planters, both in front yard and back yard. Both started to die at same time. I've tried to research it, but all I can find is that once it sets in, there's nothing I can do. But how do I prevent it? Thank you in advance for any advice.

If this is indeed what your plants have, there is probably nothing you can do, but you should destroy all the plants and either thoroughly sanitize the containers and change the soil, or use new containers next year.

If you have another fungal disease, be ready to treat the plants with a fungicide at the first sign of trouble next year.
