This is my second attempt to grow sunflowers in pots. I thought it was slugs that was eating / devouring my sun flowers, yet, I see little or no evidence that my slug pellets. Do I (I’m now thinking) have a fungus or disease eatinf at my plants? Please help - I am an absolute beginner to this.

Certified ExpertA.I can't get a good look at the soil, but this does appear to be diseased. Usually, this happens with soils that don't have a chance to dry out between waterings.
I would start fresh. Container, and all. You can attempt to sterilize that one, but it may come with many more attempts before it DOES get sterilized. Better to use a fresh pot and fresh soil. Be mindful to let it dry out between waterings, and don't feed if there is already feed present in soil.
After all of these adjustments are made, your sunflowers should do quite well. They don't seem to mind container life, and grow just find in pot.

August 25, 2021Q.Should I Cut Back My Max Perennial Sunflower After It Blooms
I live in SC and have a potted maxmillion perennial sunflower. I think it’s going to flower soon. Right now it’s about 6 to 7 feet tall. After it blooms should I cut it back and if so how far? I’ve never had one before.

Certified ExpertA.I would wait until it flowers. Once the flowers have faded, you can prune off the spent blooms. Other than this, they can be cut back by half, at any time, to promote vigor. At the end of the year, you will cut them to the ground level, as they will come from rhizome the next season.

August 31, 2021Q.I Notice Some Black Dust On One Of My Sunflower Plants And I’m Not Sure What It Is.
One of the stalks on one of my sunflower plants has what looks like some soil on it but I'm not sure if that's what it is or if it's some sort of pest or disease. Can you help me identify it and let me know what to do about it? Pictures are attached. Many thanks.

Certified ExpertA.It looks like, either, soil or insect frass. I don't see any signs of pests or disease, which leads me to believe that it is soil. Gently, blow it off.

Certified ExpertA.Once the blooms fade, yes. You can trim those at any time, but only prune the plant, heavily, in spring.

February 22, 2022Q.Question About Homegrown Sunflowers
In June 2020, we planted seeds from a packet purchased at the local home depot store into our backyard located in Venice Florida. We received months of blooming stalks of sunflowers. We then dried and removed the seeds for later planting. In Dec, 2020, we replanted some of those seeds and have grown more. The question is, the first growth had one bloom per stalk. This time, one stalk has produced multiple flowers and each flower's stem also has buds. To date, it produced one large flower with the seed bed 10" in diameter. That flower is currently drying and has been clipped. Now there are 10 more bloomed flowers and each flower stem shows one or two buds on them for a total of 9 more flowers to bloom. Is this normal? My husband has traveled vineyards around the world and has never seen this happen. Several people we have asked have also never seen this happed

Certified ExpertA.It's not unusual if the original seed was a hybrid. Seeds from plants grown from hybrids will not produce plants identical to the hybrid. Many plants today are hybrids bred to combine the best attributes of two or more plants into one. Then when you plant seeds from those, you could get attributes from any of the combined parents.
