These were one of the best performers among the Superbells I planted in my balcony railing planters. They flowered prolifically from the time I planted the young small plants just after the last frost, until I had to yank out the enormous trailing 3 foot long masses they had grown into at the end of November so I could prepare for winter/spring. A good companion variety would be Over Easy, which grew at about the same rate and size. I also planted them with Blue Moon Punch and Tangerine Punch, which were slightly less vigorous but still kept up pretty well.

Calibrachoa do not like to have constantly damp soil. They will do well in the ground only with good drainage. For most gardeners containers are the best use for Calibrachoa.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.
Woo-hoo! There is nothing more super than Superbells. If there was a word that meant extra, extra super it still wouldn't be as super as we are. Calibrachoas are a new type of plants that sort of look like little Petunias, which makes sense seeing as we're related.Superbells® Lemon Slice® Calibrachoa hybrid 'USCAL5302M' USPP 24,353, Can 4,917

Oh my goodness! We just potted some of the Lemonslices on our front porch and they are just eyepopping! I’m so very happy with them! They look just like they did the day we planted except with more blooms! No wilting at all! Wish I could say the same for my petunias!Bonnie Hoke, Texas, United States, 2 years ago
Lemon Slice has been a winner in my flower box! (I wouldn't try to grow calibrachoas in the ground. Clay soil does not work for them.) It's been the most vigorous calibrachoa I've grown!Sharon Sivertsen, Illinois, United States, 3 years ago
Since a long visit to Germany and the Alp area, I have fallen in love with cascading flowers out of windowboxes. Usually use cascading petunias, trailing geraniums, and vinca vine. Saw these lemon yellow plants last year, and planted a few as accent in my boxes. I was very pleased with the constant color, and hummingbirds & butterflies loved them too. They kept blooming until a hard freeze, and I live in Kansas so it does get cold. Plan to find some more this year. Definitely a winner!M. Mulryan, Kansas, United States, 5 years ago
Stumbled across Lemon Slice couple of years ago at Home Depot and tried some outside a B&B room (w yellow/white décor). LOVED them. Every factor associated w the write-ups of Million Bells was true for us - mounding. not fussy, last all season, love sun, etc, etc, etc. But then ... couldn't find them anymore (or the original label to even see what they were) !!! Was at a friends house and admiring a gorgeous potted mound of colour. He told me they were Million Bells and my research brought me here. I'm now planning out my colours for planting Calibrachoa all across the back of my property (where the sun shines (bakes/kills) all day. I've liked the Wave Petunia's from the last couple of years but they don't hold a candle to Million Bells - prolific and colour choices and tough enough for my mishandling. Now the challenge will be to find or order the colours I want for my place - just a retail customer so zero buying power. Can hardly wait till spring.

This is my first experience with Superbells and it's a fantastic plant. Beautiful bright yellow and white flowers with perfectly crisp stripes covered the vine in abundance from purchase to present -- and it's mid-November in New England! The buoyant vines branch to a width of about 12 inches and are 18 inches long. I went away the first week of August and forgot to ask someone to water my Superbells. I returned to a brown, fried plant with just a few yellow flowers remaining. I thought it was gone. But I trimmed off the crispiest branches and watered well, and the plant cheerfully rebounded. Now, three months later, it is crowded with perfect flowers, spilling over my plantar. It's one of the prettiest flowers in my garden and utterly care free.FCR, Rhode Island, United States, 7 years ago

LOVE THESE BABIES! Full, thriving, easy and gorgeous. Planted in 6 large pots with spikes & gerbera daisies. Gorgeous color!!! A very nice addition to any garden. PW has lovely products, reasonable prices and GREAT quality.Flower Power, Illinois, United States, 8 years ago
I saw this plant when I was delivering at you greenhouse as a UPS driver and loved it. Just bought two!!!Shannon Teall, Michigan, United States, 8 years ago
I have hung a basket of these from my front porch every year for the last five years. They are heat- and drought- tolerant (ie. forgiving when you forget to water them). My front porch gets that hot, late afternoon sun from the West which scorches and shrivels most plants. The Superbells love it! They bloom, more or less, from May to September with a slight dormant period in midsummer. They require no deadheading, though I do like to trim them back a little when they're gearing up for their second bunch of blooms in midsummer. Lemon Slice was the variety I selected last year, and I got all sorts of compliments, though we try a different color each year. I just mix a small amount of liquid fertilizer into their water every few weeks, and I am repaid with about 5 months of lush, trailing flowers. This year, I'm filling two baskets!Whammytap, Kansas, United States, 8 years ago
