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.

Self-cleaning no deadheading necessary, this is not necessarily true of all Petunias.
Late July and August is when plants should be at their best, but there is only one problem: The plants have run out of energy and the gardeners realize it too late to help the plants recover. This is especially true in raised containers and hanging baskets. Here is the best way to keep your Petunias in the Super category.
1. When you buy them in the spring, buy a slow release fertilizer to top dress the basket or container. If you plant your own basket, incorporate some of the slow release fertilizer in the soil as you plant. Follow the package directions.
2. In May fertilize with a water-soluble fertilizer once every two weeks. Mix up the fertilizer and water the plants just like you would if you were using clear water. It normally takes a good half of gallon of water
To really water a 10" wide basket or raised container.
3. In June as the weather starts to get warm to hot, fertilize weekly, again with a good soaking. If the weather turns really hot as it sometimes does in
Late June you may need to fertilize every third watering. By now the Supertunia is really growing and starting to tumble down from the basket or fill out across the flowerbed.
4. July is when the cutting back occurs. Around the 4th of July, (after your big party) get some of the slow release fertilizer that you bought in spring and re-apply across the top of the planter. At the same time, trim back
some of the longer branches just enough to bring the plant back in line with the bottom of the pot or basket. Don't remove too much at the maximum cut back 20% of the branches or 1 in five shoots. You can also just give it a general light trim. Your plant will be out of flower for a few days, but will come back stronger than ever. By now with July's heat you should be watering at least every other day and begin to fertilize every other watering. I know it sounds like a lot, but if you want a plant to grow like an elephant and be the most it can be, you got to feed it like an elephant!
5. August is, hot, humid, & sometimes with monsoons. Keep up the water and fertilizing, and again, if the plant starts to look straggly remove a few more branches but never more than 20% or give it a general trim as before.
6. It is September and the plants should still look good, start to back off the watering and the feed, but shape the basket with the last pruning of the season.
I know it sounds like a lot of work, but it really is a labor of love. I fertilize my baskets and my garden every time I water, and I water daily from mid July through August. I recently invested in the WaterWise irrigation system and let me tell you it really works. You will find that your Supertunias, along with all the rest of your plants will keep looking fantastic through September and perhaps with the luck of a gardener and a late frost maybe even into October.Supertunia® Really Red Petunia hybrid 'Sunremi' USPP 16,803, Can 2,838

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, 19 weeks 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, 1 year 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, 3 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, 3 years ago
