Tips for planting and caring for gunnera manicata
If you are looking to create a magical, tropical looking garden with somewhat limited effort, Gunnera manicata may be the plant for you. This incredible foliage plant is native to the swamps, marshes, and bogs of South America, where due to the damp soil and warm climate, it can reach up to 8ft in diameter. In the UK, however, Gunnera manicata will rarely reach anywhere near its ideal size, but that doesn’t mean you can’t make it look just as impressive with a little bit of effort.
The first step is to find a location with ample access to light and water, as Gunnera manicata needs both in order to thrive. Somewhere near your pond or river is the ideal spot, but you can also plant it in a large pot and move it around as necessary.
Once you’ve found the right place, make sure you add a thick layer of mulch around the base of the plant to help keep it moist and stop its shallow roots from drying out. The rhubarb-sized leaves of Gunnera manicata will then burst into life in the summer months, with remarkable circular shapes and toothed edges. In order to keep your Gunnera manicata looking at its best, make sure to feed it every fortnight with a liquid fertilizer, and always deadhead the flowers as soon as they have finished.
Then, to protect the plant from frost in the winter, simply wrap it in some insulation material or straw and move it to a sheltered area if needed. With a bit of regular maintenance, your Gunnera manicata will be sure to give your garden a truly tropical feel.
Common problems with gunnera manicata
Gunnera manicata, popularly known as ‘Giant rhubarb’ is one of the largest perennial plants in Britain today. It is an invasive and rather fast growing evergreen perennial species that is native to the UK and likes moist habitats with plenty of space to spread. Gunnera manicata is also known for its striking foliage and its burgundy stalks, which add vibrancy and a unique touch to any garden.
Growing and caring for a Gunnera manicata isn’t always easy. Below, I will list out the most common problems and the best ways to tackle them.
Firstly, Gunnera manicata can suffer from disease, especially if the soil it is planted in is too wet or acidic. To avoid this, it is important to choose a soil pH between
0 and 0 that retains moisture well but also offers good drainage. In addition, mounding up the soil around the base of the plant will help to increase drainage and reduce the chances of disease.
Another common problem with Gunnera manicata is its tendency to spread quickly and take over parts of your garden. It can be tempting to just dig it out, but it is important to take the time to tackle the problem root by root instead. Hand pulling the rhizomes and roots is the most effective solution, though this can be time-consuming and may require regular maintenance over a period of time.
Another common issue with Gunnera manicata is its susceptibility to frost damage. Hot summers can also cause the giant rhubarb to be susceptible to dehydration and burning.
To avoid these issues, it is best to keep the plant away from direct heat sources, provide ample amounts of water, and provide some kind of protection during the winter months. In conclusion, with a little extra care and understanding, Gunnera manicata can make for a unique and beautiful addition to any garden. Providing the right soil, controlling its spread and paying attention to potential frost damage will help you to grow a healthy Giant rhubarb, full of life and colour.
