If you want to increase sloes, you have 5 options. Each procedure has its advantages and disadvantages, but they are not all complicated.

There are a few good reasons to multiply the blackthorn (Prunus spinosa). The distinctive wild wood has long found its way into our gardens. The plants are easy to care for and a popular bird protection hedge. Tits or warblers build their nests in the thick branches and can breed undisturbed. In spring, the sloe attracts numerous insects. Last but not least, the berries can be harvested after the first frost and processed into liqueur, for example. If you want your sledge hedge to grow, or you are thinking about doing the same as your neighbor and want to plant sloes as well, then our tips and advice on how to increase the number of shrubs will be the right read for you.

1. Increase sloe through cuttings

Even laypeople will discover a growing method for themselves with the propagation of cuttings, which causes few problems and guarantees good success. The ideal time to cut cuttings is in the summer months. Older shoots that are already quite vigorous and woody shoots are suitable as cuttings. The cutting should have a length of about 20 centimeters. A few pairs of leaves are left in the upper area of ​​the cutting. Leaves and buds must be removed in the lower part, as these would rot, if they were located underground.

The cuttings are placed in a planter filled with a peat-sand mixture and placed in a partially shaded location. The cuttings must not dry out, but should also not be watered too intensely. A strong root system should have developed in spring and you can plant the sloe at the desired location.

Key word multiplication:

  • cut woody cuttings in summer
  • Remove the lower leaves and buds
  • Place the cuttings in the planter
  • Fill the planter with peat and sand
  • place in partial shade
  • water slightly over the winter
  • Plant out in spring

2. Blackthorn increase by root runners

This type of propagation will cost you little effort, because the sloe forms plenty of roots. You can cleanly separate these root pieces from the mother plant with a sharp spade. Root runners are preferably cut in spring. The root cuttings can be handled differently. You can cut off a section that is about half a meter long and immediately plant it back in the field. The planting depth should be maintained and the root cuttings should be inserted into the soil as deeply as it was at the old location.

You can also cut the root runners to a few centimeters and place them in planters, which they have filled with a nutrient-poor substrate. Ensure constant moisture in the planter and watch the root cuttings. As soon as the roots become visible on the bottom of the vessel, the sloe can be placed outdoors.

Propagation by root runners in key words:

  • Separate root cuttings from the mother plant
  • either put it directly outdoors
  • or shorten it to about five centimeters and use it in plant pots

3. Increase sloes by using sticks

Propagating plants with sticks has generally gone out of fashion. It is a very simple and particularly efficient method that even inexperienced hobby gardeners can easily try out. In winter there is little to do in the garden. A rewarding activity can be cutting sticks.

Tip: Propagation by means of sticks is particularly suitable if larger quantities of offshoots are to be used.

The plywood differs from the cuttings. As already described, cuttings are cut during the growing season. Leave a few pairs of leaves above ground and plant the cuttings in the ground. Sticks are cut during hibernation and stuck into the ground without leaves. The propagation works extremely well with both methods.

Sticks are cut from strong and well wooded shoots from the previous year. The plywood should also be cut about 20 centimeters long. It is important that each plywood has several leaf nodes, otherwise no shoots can develop and the cuttings cannot develop roots.

Sticks can be placed in planters and brought forward in the house. If you want to save yourself this effort, store the cut wood frost-free and stick it directly into the ground in spring.

Tip: Sticks are stuck deeper than cuttings. One or two leaf nodes should be underground.

The sticks are to be kept evenly moist. The sticks start to sprout after only a week.

Tip: When moving forward in the room, choose a rather cool location.

Multiplication by means of sticks:

  • Cut sticks in winter
  • either put in plant pots
  • or hibernate frost-free and put it directly outdoors in spring
  • Keep the plywood evenly moist

4. Increase the blackthorn by lowering

If you already have a sloe and you want to get this company, for example to plant a hedge, propagation by subsidence is an effective way, without much effort. Choose a strong branch. This should be able to bend down to the floor.

Make a furrow on the ground and insert the branch. The branch is covered with earth. The front end looks out. To ensure that the shoot grows upright, tie it to a wooden stick.

Tip: Weight the section of the branch covered with earth with a stone so that the lowering device cannot snap out of the ground.

If the sinker is prepared as described in early summer, the branch should have rooted itself sufficiently by autumn and can be separated from the mother plant and planted separately. If you want to be on the safe side, you can leave the sinker on the mother plant until next spring.

Multiplication by subsidence in key words:

  • lead a strong branch to the ground
  • Lay the branch in a furrow
  • Cover the middle of the branch with soil
  • Weight the branch with a stone
  • Expose the branch with its front end
  • Tie the countersink to a wooden stick
  • after rooting, separate and plant separately

5. Increase sloes by sowing

If you are not in a hurry to get new sloe plants, you can also try the sowing method. For sowing to succeed, the seeds must be stratified. This sounds more complicated than it actually is. Since the sloe is one of the cold germs, the seed must first receive the information that it is time for it to germinate. To do this, fill the seeds in a sachet filled with damp sand and place them in the refrigerator for about a month. Then sowing can take place. Choose planting trays or sow the sloe directly into the field. If you keep the seeds evenly moist, germination will start quite reliably.

Tip: The seeds can also be sown outdoors in autumn, which saves stratification or lets nature do it for you.

Propagation by sowing in key words:

  • Win or buy seeds
  • Place seeds in the refrigerator for four to six weeks
  • alternatively, put it directly outdoors in autumn
  • quite reliable germination

What happens to the young plants?

If the propagation worked, the joy is great. So that this is not clouded too quickly, it is important to care for the young plants properly. These need a sunny location to develop their dense growth and to bloom in spring. While older plants require little maintenance, it is important for young plants to water abundantly in the first few weeks. The soil should be calcareous and rather dry. The plants grow quite slowly and reach about 20 centimeters in height in the first year of standing. Since the plants are perfectly adapted to our climate, you do not have to provide any additional protection even in the first year in winter. Late frosts alone can damage the flowers. Take a look at the thermometer and, if necessary, cover the plants with fleece or a jute sack.
