So it has a place in our gardens.Ĭalibrachoa and petunia were both discovered in South America in the 19th century. The flower is similar to the Petunia, and the plant has better resistance to hot, humid summers than the Petunia. We, gardeners, love Petunias and we are happy with the much newer Calibrachoa, which looks like loads of small petunias on a colorful, mounding, and trailing plant. It fully meets the definition of what we want from a blooming annual plant. It should perform in your garden or in containers from spring to fall and do so every day. It is petunia-like, with large, wide tubular blooms in brilliant colors, and is more tolerant of heat and rain than either of the other plants. And as a cross between the petunia and the calibrachoa, it has features not found in either plant. Calibrachoa are very forgiving when it comes to trimming.Īn application of fertilizer or compost on garden beds and regular fertilization of plants in pots will help ensure the best possible performance.Do You Wish Petunias Would Last Longer In The Summer? 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. I will usually give my Superbells a trim back in late July or early August. You will sacrifice flowers for a few days, but the plants should shortly come back flowering more than ever. Just like your hair looks a lot better after a trim, your plants often will too. This will cause them to branch out more and should stimulate new growth and flowering, especially if you fertilize right after trimming them back. Grab a sharp pair of scissors or pruning shears and give the plants an all over trim. This can happen even if they are being watered and fertilized correctly. Or use our Proven Winners Water Soluble fertilizer, which has the chelated iron.Īs the season goes on the plants can sometimes just start to look open and not as good. Stop by your favorite garden center and they should be able to help you choose a product to use. 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. 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. The common form of Iron used in fertilizer is sensitive to pH changes. 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. 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. Feed them using a well-balanced (look for something with an n-p-k ratio near 24-12-17) water soluble fertilizer. If you haven't been fertilizing regularly they could simply be hungry and in need of fertilizer. If the foliage is yellow there are two possible causes. 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. Calibrachoa can be sensitive to both high and low pH. They will do best if fertilized on a regular basis.
The plants are low-maintenance with no deadheading needed. Proper watering is key to growing good Calibrachoa. In the ground they shouldn't need much additional water unless conditions are very dry. Raised beds would be a good choice for planting Calibrachoa in the landscape. If your plant is wilting even though the soil is still damp you likely have a root rot problem.Ĭalibrachoa can be fantastic in-ground plants, but only if they are planted in well-drained soil. In containers, allow the top of the soil to dry before watering again. If the roots are kept too wet it can lead to root rot diseases. While not a necessary step, it will increase branching and may help your plants look even fuller.Ĭalibrachoa are usually easiest to grow in containers.
When planting Calibrachoa I often give the plants a slight trim, using a sharp pair of scissors or pruning shears.
