Pruning begonias is an important part of their care, as it helps to keep them healthy and looking their best. Pruning can also encourage new growth and flowering. Pinching back the tips of stems will promote bushiness, while cutting back leggy stems will help to keep the plant compact.
There are two main types of pruning cuts: heading cuts and thinning cuts. Heading cuts remove the entire stem back to a bud or leaf node. Thinning cuts remove entire stems or branches back to their point of origin. Heading cuts are used to control the size and shape of the plant, while thinning cuts are used to improve air circulation and light penetration. When pruning begonias, it is important to use sharp, clean tools to prevent the spread of disease. It is also important to avoid over-pruning, as this can weaken the plant and reduce flowering.
