Forming a bonsai crown of a weeping fig is a creative process. You need to cut off all the branches that are knocked out of the general shape. Trimming should be done with a sterile and very sharp tool. Start from the bottom of the crown and move upwards to the top. Form the foliage into a crown shape similar to regular trees.
Keep in mind that in autumn and winter, plant growth slows down, unlike in spring and summer. To maintain the shape of the crown, it is better to prune it during the period of late winter and early spring. Ficuses tolerate pruning well, so don't be intimidated by this process.
To reduce the size of the leaves, simply pinch them with small scissors. The procedure is done during the summer months to maintain the shape of the tree. Similarly, cut off the roots to form a thick strong trunk. This should be done while the plant is still young, about a year. Cutting the roots, the tree begins to grow in width. You can trim up to one third of the root system. Once again, use only sterile and very sharp equipment. Do not worry: while the procedure is harmless to the ficus, it helps to accelerate the preferable growth of the plant.
