I planted two of the yellow superbells in each of two 12" hanging pots. They started out very well, but halfway through the summer one plant just died for no apparent reason. The remaining ones looked nice and had lots of flowers, but then I started having problems with aphids. I sprayed several times with insecticidal soap and managed some control, but the plants are dense and it's hard to cover all the leaves. I also discovered that I needed to apply iron occasionally to avoid the leaves yellowing. I enjoyed my plants but I don't plan to grow them again.

Calibrachoa need good drainage to perform well so they are best grown in containers of all kinds. Hanging baskets, window boxes and upright containers are all great for use with Superbells®. If you happen to have great drainage in your landscape beds or utilize raised beds, then Calibrachoa will do find when planted in the landscape. However, most of us will have better luck when using containers.Maintenance Notes:
When planting Calibrachoa I often give the plants a slight trim, using a sharp pair of scissors or pruning shears. While not a necessary step, it will increase branching and may help your plants look even fuller.
Calibrachoa are usually easiest to grow in containers. If the roots are kept too wet it can lead to root rot diseases. In containers, allow the top of the soil to dry before watering again. If your plant is wilting even though the soil is still damp you likely have a root rot problem.
Calibrachoa can be fantastic in-ground plants, but only if they are planted in well-drained soil. Raised beds would be a good choice for planting Calibrachoa in the landscape. In the ground they shouldn't need much additional water unless conditions are very dry. Proper watering is key to growing good Calibrachoa.
The plants are low-maintenance with no deadheading needed. They will do best if fertilized on a regular basis. Calibrachoa can be sensitive to both high and low pH. If your plants have been growing for a while and then begin to look a bit tired and not so good there are several things to try. If the foliage is yellow there are two possible causes. If you haven't been fertilizing regularly they could simply be hungry and in need of fertilizer. Feed them using a well-balanced (look for something with an n-p-k ratio near 24-12-17) water soluble fertilizer. If you have been fertilizing regularly with a well-balanced fertilizer and the foliage is still turning yellow, it is probably because the pH range in your soil has gotten a bit high or low. The most common impact of this is that Iron can no longer be taken up by the plant, even if it is available in the soil.
The common form of Iron used in fertilizer is sensitive to pH changes. If you think pH is your problem you can either try to lower (or raise) the pH or you can simply apply Chelated Iron, which is available at a wider pH range and should help your plants turn green again. You may also be able to find Iron in a foliar spray (which means you spray it on the foliage rather than applying it to the soil) which can also help your plant turn nice and green again. Stop by your favorite garden center and they should be able to help you choose a product to use. Or use our Proven Winners Water Soluble fertilizer, which has the chelated iron.
As the season goes on the plants can sometimes just start to look open and not as good. This can happen even if they are being watered and fertilized correctly. Fortunately this is very simple to fix. Grab a sharp pair of scissors or pruning shears and give the plants an all over trim. This will cause them to branch out more and should stimulate new growth and flowering, especially if you fertilize right after trimming them back. Just like your hair looks a lot better after a trim, your plants often will too. You will sacrifice flowers for a few days, but the plants should shortly come back flowering more than ever. I will usually give my Superbells a trim back in late July or early August. Should your plants have a few unruly stems that are longer than everything else or sticking our oddly, you can trim these stems back at any time. Calibrachoa are very forgiving when it comes to trimming.
An application of fertilizer or compost on garden beds and regular fertilization of plants in pots will help ensure the best possible performance.Superbells® Yellow Calibrachoa hybrid 'Balcal1004' USPP 29,528

Have bought a super bells yellow every year since 2008 so I didn't know what to expect with the "new for 2017" ad. So far 2 improvements stand out for me: 1. Branches are stronger and sturdier. 2. Flowers are somewhat larger. I have 2 of these new for 17 editions and am very well pleased. Each shares a pot with other PW plants and is thriving. Both get only afternoon sun, about 4 hours direct and then late day shade. All I do is water regularly and fertilize every 10-12 days. They spread and mound equally well so they can be used for spillers and fillers. Only downside...this year the Japanese beetles have added some of my callies to their diets but damage has been negligible. Aphids, on the other hand, love to munch on callies so I have to keep close watch. Still I highly recommend this plant as the yellow is as good as it gets, the blooms last a while and there are dozens on them all the time.Matthew Lamb, Maryland, United States, 3 years ago
