Steve Need Dahlia Help

[Nyboy]

I have 2 mini dahlias I got from supermarket. Each one is planted in cement planter. Morning shade about 11am on full sun. Both plants covered in buds that turn black, rare bud opens to flower. Have noticed a lightening up on leaf color. Ready to send to compost pile.

I was just thinking yesterday how using Bayer 3 in 1, with its fungicide, and alternating with Spectracide fungicide keeps black spot off the zinnias so that I don't even need to worry about it showing up.

That's the zinnias. The dahlias still get a bacteria that causes the stem and buds to deteriorate.

If they were big plants, you could undercut the problem. Small plants, maybe that isn't possible. Garbage can is safer than compost pile.
