Fertilize columnar fruit properly
Despite the relatively compact size also column fruit can deliver a surprisingly high fruit yield. In order to ensure that the plants have the necessary nutrients at hand, care must be taken during planting and during further care to ensure that fertilization is precisely tailored to the needs of the plants.
The misunderstanding in the fertilization of column fruit
Some fruit-loving hobby gardeners are prone to exaggerated restraint when using pillar fruit. Apparently, in some gardens, the view is that a consistent fertilization of daintily viewed young plants would lead to an undesirable proliferation in plant growth. However, this may only be very limited in the case of the fruit trees grown specially for use as columnar fruit, since the growth habit is genetically defined in most cases. Pale fruit was usually selected for a particularly high fruit yield. Therefore, it is important in particular in the culture in the planter, always nachzuliefern sufficient amounts of nutrients for the formation of fruits. This is only partially possible with compost and animal manure, which is why it is recommended to use long-term nutrient fertilizers in liquid or solid form (grained) for the fertilization of column fruit.
When planting and repotting fertilize the same
If pillared fruit varieties such as column pear or column plum are planted in the field, the planting hole should be dug at least twice as large as the rootstock of the trees. Thus, a good foundation can be laid for later growth by filling the planting hole with a mixture of garden soil, mature compost and manure. Also bucket cultures tolerate a certain amount of organic fertilizer right from the planting stage. This can be renewed each time the substrate exchange when the trees are replanted every two to three years in a larger planter. For the long-term fertilization of the substrate, the following fertilizers are suitable (among others):
The right time and the interaction of different fertilizers
Pale fruit should be fertilized at least once a year, but it can also be twice a year fertilization appropriate. First of all, a fertilizer should be given to the plants in the spring as soon as the first leaves leave. In this fertilization, a nitrogen-stressed long-term fertilizer for fruit trees can be used. The contained nitrogen stimulates the formation of leaves and the growth of the plant mass, thus laying the foundation for a good yield. In the late summer, a second fertilization can be made, in which, however, a fertilizer with low nitrogen content should be used so that it no longer comes to the formation of new shoots just before the onset of winter. The fertilizer for the late summer fertilization of the column fruit, however, should increasingly contain potassium and phosphate. These substances promote the lignification of young shoots and thus provide the necessary winter hardiness of the plants.
Tips
It is not always due to a bad location or the wrong manure, if the yields of pillared fruit vary greatly. It can happen with column apples that after one year with a very high fruit set in the following year hardly flowers on the tree are to be discovered. This is because the plants grown on a high fruit yield "consume" so much energy to ripen the fruit that there is hardly anything left to plant the flower buds for the following year. For this reason, e.g. Parts of the possible harvest are removed in advance on particularly rich column apples and only about 20 to 30 fruits (depending on size and variety) are left to ripen on the tree.
