I planted two Really Red plants in a 12" hanging pot in a sunny location, watering and fertilizing regularly. Really Red did not grow as large as my other supertunias, but they were reasonably full. The flowers were a pretty color, but there never were very many of them. Eventually by late July the flowering really declined. I saw no sign of bugs. In mid-August I gave up and discarded the plants. I grow a lot of supertunias and most do fine, so I don't know what happened here. I don't plant to grow this variety again.

These are heat tolerant plants, that aren't particularly fussy and need little routine maintenance. They will perform best if an application of controlled release fertilizer is included at the time of planting. This applies to both landscape and container plantings. Supertunias are heavy feeders, but a single dose is usually sufficient for landscape beds in most climates. If you have a very long season, a second application of controlled release plant food should be considered for landscape plantings. In general, containers need to be fed more than landscape plants. Supertunias in containers will need to be fed more regularly to be their absolute best. A second application of a controlled release fertilizer can be applied about every two months to container plants, which will help. However, for the very best performance I find regularly applying water soluble fertilizer starting about two months after the containers are planted gives the best results. These extra applications of plant food really makes a difference in performance through the summer.
If your plant begins to look open or a bit tired, an allover trim can be beneficial. Use a sharp pair of scissors or pruning shears to trim back up to 1/3 of the volume of the plant. I pair any trim with a dose of water soluble fertilizer to provide instant energy to help kickstart new growth, branching and flowering. Your plant will take a week to recover from the trim, but the end result is a fuller plant with more blooms going forward. You may repeat the trim as needed through the season.Supertunia® Really Red Petunia hybrid 'Sunremi' USPP 16,803, Can 2,838

Have had great success in prior years pairing supertunias with fanflowers in my 10" x 10" container. This year I am using PW Really Red which I purchased and potted Memorial Day. It is now June 14 and have one remaining bloom left. All others had to be handpicked...did not deadhead by themselves. No more buds are visable on the supertunia, though lots of green foliage, and the Scampi White Scaevola aenula is blooming like crazy. The container is in a protected location on my porch with plenty of sun and I am using a water-soluble, balanced fertilizer. Hope it gets a 'second wind' soon, but right now I can't say I'll purchase another.Linda Schneider, Wisconsin, United States, 1 year ago
My friend went on an RV trip and stopped by my favorite nursery, Half Moon Bay. It was too early in the season so all they had was red and white PW petunias, darn!. The white wasn't even the new Vista Snowdrift. Plain red and white? I stuck them in my cold greenhouse to await companions to plant them with. The red petunias got aphids and were running out of the pots. I was forced to trim and spray them when I planted them in a 20" pot with bacopa and diamond frost euphorbia. Flash forward to June and I have a huge fluffy pot of white on one side of the walk and a perfect round cap of red on the other side. Both are in big blue ceramic pots, striking. We have already had a run of *100+ days. Really Red is a strong grower in zone 9b. I would like to pair it with Supertunia Limoncello so I will be hoping to buy it again. Plain Supertunias are never plain.Peggie Who, California, United States, 1 year ago
Have one of these, sharing a 14 inch pot with single callie. Bought from PW Certified Center nursery so maybe that helps. That said I have nothing but good things to write thus far - Memorial Day weekend 2019. The plant itself is sturdy and without blemish with the typical deep darker green foliage to which I have become accustomed from PW. At any given time the plant has 15-20 full size blooms and they last 2-3 days. Really Red is more of a spreader than I thought too and will soon need a trim. All it gets is water, fertilizer and 4-5 hours strong afternoon sun. Would recommend this as the red is genuine and true.Matthew Lamb, Maryland, United States, 2 years ago
I grew Really Red Supertunia this year for the first time and had high expectations. We have had an exceptional amount of rain this year in Southern Mississippi at close to 80 inches through mid August. I think this has led to a little bit of stem and bloom rot on this variety. I am growing this in a 12 inch hanging basket which I faithfully use my fingers to do a little cultivation of the soil to loosen up around the roots due to all the moisture we have received. This seems to not help as much with the other varieties. Best Varieties I have had luck with are Vista Bubblegum (Exceptional), Raspberry Blast (Very Good), Black Cherry (Very Good) and White (Very Good). Have not tried them all yet. Would like to try Vista Fuchsia next year. Supertunias certainly like liquid food at least every two weeks.Jeff Schneider, Mississippi, United States, 4 years ago
I have been waiting for a red petunia to put in my window boxes. the last 2 years I used The Proven Winners light purple Supertunia. I would put two in a 36-inch window box and they would fill the window box and Cascade all the way to the ground. This year I put in the new really red and it's starting to go over the window box edges but very slowly. One thing I noticed is it does not deadhead very easily. I end up picking some off everyday. We'll see how the rest of this summer goes.anonymous, United States, 4 years ago
