How to Prune Cane-Like Begonias


When cultivating huge forms of cane-like begonia, such as the angel wing begonia (Begonia ‘Argenteo-guttata, zones 10b-11a), pruning is an essential component of the care routine. According to the University of Florida IFAS Extension, begonias (Begonia spp.) are commonly planted as annuals or as indoor plants; nevertheless, many begonias are capable of growing perpetually in frost-free locations within the plant hardiness zones 8b to 11 of the United States Department of Agriculture. When given favourable circumstances, they exhibit strong growth; hence, many kinds need frequent trimming to be kept in control. Begonias that are cane-like or fibrous react well to trimming at any time of the year in order to keep their growth under control and to enhance their form. Older plants, in particular, need periodic harsh pruning in order to reinvigorate their development. This is because robust plants often take on the look of being lanky as they get older, therefore older plants specifically require this kind of pruning.

Pruning Cane-Like Begonias

Some gardeners like to let their cane begonias to reach their full height potential, while others favour performing periodic pruning in order to keep the plant’s growth under control and improve its overall beauty. It is in the plant’s best interest to begin the process of pruning while the plant is still in its younger stages so that the desired kind of development may be encouraged before the plant gets too huge and spindly. When the plant is around 6 inches tall, the Chicago Botanic Garden suggests beginning pruning by pinching off the primary growth points to stimulate lateral branches, which will sprout over the course of a few weeks. This may be done when the plant is approximately 6 inches tall. As the canes develop, eliminate any that are visibly taller than the others by cutting them off at the base using pruning scissors that are sharp and spotless.

Cane begonia plants should be trimmed by pinching off the top two inches of growth from the tips of the branches. This will stimulate branching and give the plant a thicker, bushier look. The information provided by Costa Farms. You may use your fingers or a pair of sharp, clean pruning shears to pinch off the growth that is located right above a pair of leaves. It is possible to start a new plant from the growth that has been clipped by placing it in a container filled with wet soil and covering it with a big plastic bag. It just takes a few weeks for it to root if it is maintained in warm circumstances.

Rejuvenation Cane Begonia Pruning

Begonias that look like canes and are getting on in years will, at some point, need to have their growth cut down and clipped. To keep the plant from being too stressed, carry out this procedure in a measured manner over the course of many years. The Seattle Times suggests doing rejuvenating trimming in the spring, just as the plant is beginning to emerge from its dormant phase throughout the winter. Reduce by one-third the height of the canes that are the oldest and tallest, making a cut at a 45-degree angle right above a pair of leaves that are closest to the ground. Repeat this process every spring for the next three years, until even the canes that are the oldest in the garden have been given new life.

After eliminating the canes that were the oldest and tallest, pinch back the remaining canes to a height that is comfortable for you. To stimulate lateral, or sideways, growth, cut back the growth to the point where it is just over a pair of leaves. Begonias with cane-like stems should be given some fertiliser a few weeks after the spring trimming to stimulate new growth. Fertilizing fibrous, or cane-like, begonias using a quarter teaspoon of 15-15-15 fertiliser that has been diluted in one gallon of water is something that is recommended by Logee’s Plants. This is especially the case if the plant is growing in highly sunny settings.

Maintaining Safe Pruning Tools

Cane-like or angel wing begonias do not experience the mildew problems that plague many other types of begonias; nonetheless, if unclean or dull shears are used to trim these types of begonias, they are more likely to get fungal and bacterial infections. Maintain a keen edge on the blades of your pruning knives and shears at all times, and swap them out altogether if they get to the point where they can no longer be sharpened, or if the blades have nicks or pits in them. It is essential to give your pruning tools a thorough cleaning after each use, and this is especially true if you have used them on a plant that is known to harbour disease. Wash them in water that is hot and sudsy, then thoroughly rinse them in water that is clean before drying them off with a towel.

Sanitizing the blades of the pruning shears by soaking them in a solution can help eliminate any lingering infectious agents. It is recommended by the University of Florida IFAS Extension that pruning equipment be disinfected using a home disinfectant that is at its maximum strength in order to eliminate common garden diseases. Instead of washing the solution off, you should dip the blade in it and then let it to dry naturally on the blades.
