• As its name suggests, this form is constituted two carpiferous branches forming a U. It is used for apple, pear and peach trees. Allow 60 cm apart for apple and pear trees, and 1 m for peach trees.
• The simple U is driven on the necessary reinforcement for the espaliers and contre-espaliers as previously described. Cut the scion about 30 cm from the ground in March of the year following planting, above two opposite eyes (one on the right, the other on the left). Lift off all other eyes. Begin by patting the two growing shoots obliquely, so as not to risk breaking them by bending them too hard. Subsequently, bring them horizontally, then crank them and palis the vertical parts against the slats of the frame. The two carpenters will be 30 cm apart for pear and apple trees, 50 cm for peach trees.
• The following years, prune each carpenter about 30 cm from the previous size point, above a front eye (located towards you), which will lengthen the branch.
• This is, in fact, two simple Us carried by the same scion. When planting, observe 1.20 m spacing for pear and apple trees, and 2 m for peach trees.
• Start by trimming the scion at 20 cm from the ground, so as to form a simple U first.
• The following year, tgo to the two arms of the U, slightly above the bends and above two lateral eyes; these eyes will give shoots that will then bend and trellise, as for a single U. Remember to remove all unnecessary eyes.
• The following years, cut each time about 20 cm above the previous size, making sure that the four carpenters remain at the same level.
