Advised pruning of trees on GiSelA®-rootstocks.

WHY to prune?

Small trees have to be pruned so that a sufficient number of new shoots are built. These provide for an adequate mass of leaves, necessary for the production of a great number of fruits of good quality.

 

WHEN to prune?

Cherry trees can be pruned from March to September. In this period, wound healing is warranted.

 

Pruning in spring (no earlier than bud break until just before flowering) encourages growth and is appropriate to enhance growth. Most pruning measures are done now.

 

In summer (after harvest, August or September) the top should be pruned back to the desired height and width (if the top has become broader than the lower part of the tree).

 

In areas, in which cherries suffer from wood diseases (to be recognized by frequent incidence of gummosis), it is advisable to prune only at times with low danger of infection, that means not during rain and high humidity, but at the beginning of a long dry period.

 

HOW to prune in the first years after planting?

For home gardens it is easy and makes sense to train the tree as a spindle. Aim is a crown in the form of a more or less broad cone with a central leader and weaker lateral fruiting branches arising from this leader

 

3 essential types of pruning measure are important for the building of a spindle.

 

Heading of laterals: Laterals are pruned back to about 50% of their length in spring. The last remaining bud should point outwards, as an upward bud would grow into a strong and steep shoot.

Enhancement of branching: Some cultivars branch easily, others hardly. Long, unbranched laterals have to be cut in order to encourage side branching

 

Avoid that the top becomes broader than the lower part of the tree: If strong shoots have developed in the upper part of the crown, which shade the lower part of the crown and disturb the cone shape of the canopy, up to half of the length of the new grown shoots in the upper part of the crown should be removed.

 

HOW to prune from the 4th/5th vegetation period on?

In the 4th or 5th year, the architecture of the tree is established and the tree enters the phase of full cropping. Now, growth has to be enhanced by yearly pruning, to ensure high yields and good fruit quality over many years. If trees on GiSelA® are not pruned regularly, too few new shoots are built, bare wood and overcropping with relatively small fruits can be the result. Besides, pruning enhances good light and air penetration in the crown and the tree is restricted in height and kept within the allotted space

 

Begin to prune yearly, when average shoot growth in the last growing period is less than 30cm. The length of yearly shoot growth can be best recognized in winter.

 

Pruning in spring

First remove dead and diseased parts and weak, pendant and inside limbs.

After that, too steep limbs are totally removed or pruned back to flatter ones, i.e. the upright shoot is cut off shortly after (looking from the leader) one outward growing lateral, the lateral remains. This may be especially necessary for branches in the upper part of the crown to maintain the cone shape of the tree.

Shoots hanging downwards are cut off at the trunk or pruned back to a more upright lateral limb.

If growth is very weak (too little new shoot growth, too many small fruits) the following measures should additionally been taken.

 

Cutting back into older wood: Some branches are pruned back, so that about half of the complete length of the branch is removed. The cut is done about 1 cm after (looking from the trunk) a spur, with attention to the direction of the spur – as with pruning back to a bud of the 1-year-old wood. Spurs are inserted on 2- year-old and older wood and consist of 2-8 flower buds arranged around a terminal shoot bud. By cutting directly behind a spur, the growth of the vegetative bud is encouraged, and in the next vegetation period the terminal bud produces a leafy shoot.

Heading of 1-year-old shoots: Some of the branches the new wood (grown in the last vegetation period) is shortened to about 1/3 to 2/3. Take care for the position of the last remaining bud. If stronger growth is wanted, cut back to an upper bud.

Pruning measures after harvest

 

As soon as the tree has reached the intended height of 3-4 m, the leader is pruned back to a favorable, weaker lateral. This procedure can be repeated if necessary in later years. Thanks to the GiSelA® rootstock, the tree does not react with steep, strong shoots in the top and can be kept without problems at a desired height (e.g. 3,5 m).

 

If the tree is very vigorous: Occasionally (not each year) one or a few older branches are sawn off directly at the leader.
