Pale fruit is becoming increasingly popular. The slim breeds need little space and are suitable for growing in tubs as well as for a fruit hedge on small plots. For this they are considered to be particularly easy to care for and profitable. However, there are some fundamental differences to larger fruit trees when it comes to slicing and caring for column fruit. In addition, columnar-growing stone fruit is cut differently than corresponding pome fruit.
Cutting tips for column fruit
Although columnar apples and slender growing cherries and pears are all sold as pillar fruit, there are major differences in growth behavior. Thus, a columnar growth is inherently anchored in the genes only in apple varieties such as 'Mc Intosh'. All column apples are derived from this particular clone - they therefore need no regular cut and carry their fruit wood directly on the trunk. If your column apple has formed a longer side branch, you should remove it directly at the trunk at the so-called Astring. Do not leave branch stumps, otherwise unwanted side branches will emerge again.

Pear shapes are also offered in pear, plum, plum and sweet cherry. These are always readouts or varieties that grow more slenderly than usual and have been refined in the nursery on weakly growing rootstocks. Above all, cherries and pears still form more side shoots than column apples and carry the majority of their fruit wood - strictly speaking, this is not a real pillared fruit. Therefore, one must also proceed differently when cutting these types of fruit: Cut longer branches only to a length of 10 to 15 centimeters. Each branch should be cut behind a down-facing eye. The best time to do so is the second half of June. This is the best way to slow down growth and the trees use more flower buds.

Pale fruit needs large planters
It is important that you transplant newly purchased perennial fruit in a larger bucket, because the pot in which the trees are sold, is too small for a lasting culture on the terrace or balcony. The trees need a lot of earth volume for the most balanced water balance possible. In too small pots in summer they quickly suffer from lack of water and then throw off their fruits. Choose a jar that is at least 20 liters in volume and place the pillar fruit in high-quality, structurally stable potting soil. Since fruit trees like to grow in loamier substrates, most species appreciate it very much, if you enrich the potted soil with clay granules or fresh clay or Tonbröckchen. A large planter is also important for the stability, because column fruit is two to four meters high, depending on the type of fruit and processing base. The pillar fruit does not need a supporting pile, as, for example, with column apples, the "M 9" fracture-prone processing base is generally not used.
If the pots are large enough from the start, it is enough to repot the pear fruit every five years in a larger container. Fertilize in the spring with a slow-release organic or mineral fertilizer, and every two to three weeks you should re-fertilize with a liquid fruit and vegetable fertilizer, which is administered with the irrigation water.

This ensures evenly high harvests
Above all, columnar apples are very much prone to fluctuations in yield, and experts also call it alternation. In a year, they carry countless fruits and then usually have no more strength to even create flower buds for the following year. For this reason, consistent thinning of the fruit hanging is very important: Ripen a maximum of 30 apples per tree and remove excess fruit by the beginning of June at the latest. A thinning of the Fruchtbehangs is also required for peaches and pears. For cherries or plums you can do without this measure.
