Apple 'Beautiful from Boskoop' - Red winter apple - care and harvest time: beautiful

An apple tree not only serves as a shade dispenser in the home garden, but also supplies the hobby gardener with numerous fruits, even when properly cared for. Who prefers sour apples, is well advised to grow a Boskoops! Because this winter apple has a particularly high acidity, which makes it particularly suitable for applesauce or baked apples.


The Boskoop is a very vigorous apple tree that grows both in height and in width. Because the winter-hardy tree can reach a stature height of up to 4.5 meters and forms over the years a particularly expansive crown. Accordingly, when choosing the location, it is essential to ensure sufficient space, whereby a planting distance of at least two meters must be maintained. Likewise, he should not be too close to walls or buildings, especially since the flat growing root system could lift the stones of paved paths. The Boskoop also grows best when the site meets the following requirements:
  • Climate not too rough
  • ideal is a humid place
  • full sun to partial shade
  • too much shade affects the bloom
Tip: In particularly cold regions, it is advisable to grow the Boskoop in a sheltered place. Its flowers are extremely sensitive and could be destroyed by the frost.


The cultivation as well as the professional care of an apple tree does not promise a profitable harvest. Because all apple trees are considered self-infertile and therefore need a pollinator. In order for the pollinator tree to function as a pollen donor, it must be within a radius of about 20 to 30 meters and flower at the same time as the Boskoop. The following apple varieties are therefore very good as a pollinator for the Boskoop:
  • Berlepsch
  • Cox orange
  • Idared
  • James Grieve
  • Jonathan
  • Yellow Transparent
The Boskoop tolerates neither dryness nor waterlogging, which is why the optimal substrate is crucial for the growth of the tree. Thus, sandy soils are rather less, whereas deep humus-loamy soils are considered optimal. In order to promote the extensive growth of winter apple, it is therefore advisable to plant it in a soil with the following characteristics:
  • heavy and calcareous
  • damp
  • moderately nutritious
  • slightly sour are neutral


Apple - Boskoop

As a rule, fruit trees are purchased as container goods, making year-round use possible. However, it is advisable to plant the Boskoop either in spring or autumn. However, if the tree is planted in the soil in the summer, it must be watered daily in order to grow at all. To make planting as stress-free as possible for the tree, the root ball should stand in the water for a few hours. Then the Boskoop can be planted as follows:
  • Dig out the planting hole
  • about twice the size of the root ball
  • Loosen the soil well in the planting hole
  • Cut off damaged roots
  • Insert tree upright and in the middle
  • Finishing point about 10 cm above the surface of the earth
  • Fill earth hole with earth
  • ideally mix in some compost
  • gently shake the tree in between
  • so that the earth starts well
  • Gently curb the earth
  • thoroughly immerse


For freshly planted apple trees, there is a risk of buckling in strong gusts of wind. Therefore, it is advisable to provide the young trees with a support so that they can not tip over in strong winds. Various methods are available for this, with the Boskoop supporting it with a simple peg being particularly well suited. This is best done before planting as follows:
  • hit the edge of the planting hole
  • about 15 cm deep
  • Distance to the tree trunk at least 20 cm
  • Tie the tree to the stake
  • best with a Kokosseil
  • Knot rope ends firmly


Freshly planted apple trees usually require no additional fertilizer charges in the first few years. Ideally, the soil was enriched with compost during planting, which provides the trees with sufficient nutrients for the coming months to years. In the following years, however, the apple tree can be fertilized, whereby preferably organic fertilizers are used. However, care should be taken that over-fertilization should always be avoided. Because this will indeed promote growth, but at the expense of fruiting. When fertilising, therefore, the following should be considered:
  • best are organic slow-release fertilizers
  • Eg: stable manure or compost
  • Fertilization takes place in spring and May or June
  • fertilize from June onwards
  • Otherwise shoots can not mature
Tip: Falling leaves are ideal as a natural fertilizer, because when they rot, it releases valuable nutrients to the tree.

to water

The Boskoop wants to be watered regularly because it responds to both dryness and waterlogging sensitive. Inadequate water supply can be seen, among other things, in bursting or throwing off the fruit. On the other hand, a too wet ground can cause considerable damage to the health of the tree. Therefore, the irrigation needs a bit of tact, and the following tips are useful:
  • pour about every week
  • upper layer of earth should never completely dry out
  • Irrigate soil well up to 20 cm deep
  • best with rainwater
  • stale tap water is also suitable
Tip: An extensive mulch layer not only supplies the tree with nutrients, but also reduces water evaporation.

To cut

Apple trees are usually cut once a year, with young trees excluded. The cut can be done both in spring and autumn, as long as the temperatures are above 5 degrees. With a regular cut not only the shape of the treetop is kept in shape, but also promotes the health of the plant. If the tree is also regularly lighted, the risk of "alternance" is reduced. This is a variation of the fruit yield, so that the tree only bears big fruit every two years. It is therefore advisable to cut off the following shoots every year:
  • dead and sick branches
  • down and inward growing shoots
  • Disabling branches
  • Competitors to the lead boxes
  • Competitors to the center branch
  • Water shoots (upward growing shoots)
When cutting it is important to ensure that three to four Leitäste always remain, otherwise again form numerous water guns. The fruit wood should also not be cut off, as this is followed by the flowers and subsequently the fruit. However, these can be shortened in exceptional cases, when the shoots grow particularly strong down. It is important to ensure that is cut short over a bud, which points outward.


Although the Boskoop can be propagated by sowing, this method is not necessarily recommended. As a rule, the plants are comparatively weak and bear little fruit. On the other hand, propagation through refinement is more common and promising, with oculation being the most recommended option for the Boskoop. Although this method requires a bit of tact, but it is particularly popular among hobby gardeners. In order to multiply the Boskoop by means of Okulation, it first requires a scion and a base:
  • is won by the mother tree
  • mature, pencil-thick shoot
  • Cut off the leaves
  • only stubs should remain
  • comes from the same botanical family
  • best a weak growing apple tree
  • remove all side gears
Instructions Okulation
After both the yummy rice and the base have been prepared for the Okulation, the actual finishing can be continued. For this purpose, a T-shaped cut is first scratched into the bark of the pad and then the bark detached and unfolded. Then the eye is removed from the scoop as follows and inserted into the pad:
  • Cut a bud from the middle part of the scion
  • preferably a well-trained eye
  • in this case cut from below towards the shoot tip
  • just cut through the bark, not deeper
  • Push the precious eye into the T-section of the base from above
  • Cut away the supernatant of the eye flush
  • best with a horizontal T-cut
  • Wrap the finishing station
  • this is Bast or a Okulationsband
  • Seal the cut wound with tree wax or precious resin
Note: If the Okulation was successful, a freshly expelled eye shows up in the following spring.

Harvest and storage

The Boskoop is usually harvested from mid-October to November, but the fruits are then not consumable. Because the Boskoop is one of the winter apples, which after harvesting a so-called ripe for consumption need to develop their full aroma. The ripe for consumption lasts from about December to April, whereby it begins only during the storage. For the Boskoop to develop its strong aroma, the following factors must be taken into account during harvesting and storage:
  • Rather harvest fruits late
  • this extends the durability
  • Storage at about 3-4 degrees
  • Apples are stable until about April
Tip: If the apples become crumbling during storage, this is no cause for concern. Although the fruits have lost water, but the taste is particularly intense.

Diseases and pests

Apple malus sick

The Boskoop is particularly susceptible to the core rot, which, however, can be seen only when slicing the fruit. Characteristic of the rot is a red-brown discolored core housing, where the discoloration can spread to the entire fruit. To prevent the nuclear blight, an annual cut and the removal of fruit mummies are recommended.In addition, it is advisable not to harvest the apples too late and to pay attention to the low fertilizer content of nitrogen. In addition to nuclear rot, the following diseases and pests pose a threat to the Boskoop:
  • flesh browning
  • collar rot
  • codling moth
  • aphids
Note: The Boskoop is considered to be less prone to scab and mildew.
