Product Highlight Bibaum ® MAZZONI – The double leader plant Lower production costs, better fruit quality. The double leader plant is already formed and is ready to be planted in the orchard at the time of purchase. The double leader plant is balanced and symmetric. What is a Bibaum®? The Bibaum® is a plant with two balanced leaders. The difference lays in the fact that we have used an innovative production technique in the nursery with two well-balanced leaders, ready for planting in the orchard. The production process of Bibaum® plants in the nursery was patented first in Italy, then in all of Europe and later also in the United States. It met with great success in all these contexts.
