Strawberry tree (Arbutus unedo) in the garden? Then you are one of the lucky ones who can enjoy this unusual plant. You will surely get admiring glances and will be asked every now and then when strawberries have been growing on trees. The propagation of the plants is a very special challenge. If you succeed, you will be able to give away real gardening happiness or enjoy several specimens yourself.
The rather high prices for strawberry trees available in specialist shops also suggest that the number of ornamental plants should increase. We would now like to tell you how the strawberry tree can be propagated and how you can grow healthy and strong young plants.
How can the strawberry tree be propagated?
Strawberry trees can be propagated by cuttings or by sowing. The propagation of cuttings is quite straightforward. Patience and horticultural skill will be necessary for the propagation with seeds.
Multiply strawberry tree by cuttings
In order to propagate the strawberry tree through cuttings, you must already have a well-developed plant. Then cuttings can be obtained easily and uncomplicated and grown to new plants.
The propagation of cuttings step by step
- Cut the cutting
- Prepare the cutting
- Place the cuttings in the planter
- Place the cutting light and warm
Late summer is the best time to cut the cuttings. The older, half-wooded branches are cut. The cutting should have a length of about 15 centimeters. Make sure there are enough leaves. The cutting should have at least four pairs of leaves. Only the top two leaves are left on the shoot. Each cutting receives its own planter. Use growing soil that can be enriched with compost.
In order to promote rooting, the planter is provided with a plastic hood. The cutting should be given a bright window seat, but not in the blazing sun. The temperature should be around 18 degrees. The propagation appears successful when new shoots appear on the cutting. This is the guarantee for successful root formation. Now watch the cutting. If the roots grow out of the bottom of the pot, it is high time to put the young plant in a larger planter.
Strawberry trees multiply through seeds
If you get your seeds yourself, you can bring them back into the earth almost immediately. Commercially available seeds should initially soak in warm water for about a week. This has a simple background. Since the seeds are used to different seasons, they must first be exposed to a cold stimulus. This gives them the signal for the start of the new season and thus for germination. Those who fail to do so will be unlucky and will probably wait in vain for the hoped-for germination.

➔ Tip: Be careful not to let the soil dry out.
Growing from seeds step by step
- Sow fresh seeds immediately
- Water purchased seeds beforehand
- Do not cover seeds with soil
- Place the planter in the shade
- Rearing at around 20 degrees
- Do not let potting soil dry out
What happens after germination?
First, the seedlings are left in the planter and continue to be watered regularly. The planter can now move to a partially shaded place. The seedlings must continue to be protected from direct sunlight. If other pairs of leaves have formed in addition to the cotyledons, the young plants should be placed in larger plant pots. If the plants have developed well, they are placed in the planter, where they will spend the next few years, because the strawberry tree cannot tolerate being replanted several times.
What should be considered when repotting?
Strawberry trees grow rather slowly. Repotting will not be avoided in the first few years. Older plants, on the other hand, no longer want to move and should be allowed to remain in the container or outdoors.
The best time for repotting is early spring. Choose the new planter a lot larger than its predecessor so that the plant is given enough space and does not have to be repotted every year. The planter should have sufficient drainage holes so that the irrigation water does not build up in the plant pot and waterlogging occurs. Drainage is an effective protection against waterlogging. To do this, place coarse sand, gravel or shards of clay on the bottom of the vessel. Carefully place the strawberry tree in the new planter, fill up with fresh soil and water the plant well.
If perennial strawberry trees are to be moved outdoors, place the planter in the desired location a few weeks before planting. So the plant can acclimatize well and will tolerate the unwanted move better.
➔ Tip: Transplanting means extreme stress for the plant and should be avoided if possible. Older plants are no longer implemented.
