Plant Spiraea properly
The optimal time window for planting is from August to October. Alternatively, plant the spirea in the thawed soil in spring. While the soil is meticulously weeded and raked, soak the root ball in water until no more air bubbles appear. Dig a spacious planting pit to enrich the excavation with compost and horn shavings.(32.93€) Then pot the young spar and plant it in the middle. The previous planting depth should be preserved as far as possible. The substrate is consolidated with the hands in order to spread and water a layer of foliage. Finally, the Spiere receives a plant cut. To do this, shorten all shoots by half to two thirds.
care tips
Properly planted, a spirea rarely requires horticultural attention. In order for the opulent abundance of flowers, the dense foliage and the beguiling fragrance to unfold, the following cultivation is important:
If you plant a spirea tree in spring, a sufficient water supply during the summer comes into focus. In contrast to planting in the rainy autumn, during the dry season you cannot avoid going regularly to your pet with the watering can in your hand.

Which location is suitable?
One of its outstanding attributes is its flexible attitude towards site conditions. Spiraea thrives splendidly in sunny to semi-shady locations and will not let you down even in light shade. The ornamental tree spreads its roots in any normal garden soil, which may be calcareous. The only thing the gem doesn't want to be bothered with is waterlogging.

The right planting distance
In order to skilfully measure the ideal planting distance, please take a look at the expected growth height and width. Since the genus offers everything from dainty dwarf varieties to mighty flowering towers, we have compiled recommended distances for popular species for you:
When measuring the planting distance, please bear in mind that the majority of Spiraea species thrive almost as wide as they are high. In addition, numerous trees and shrubs show a rapid growth rate of up to 50 cm per year, so that apparent gaps are filled within a short time.
When is flowering time?
Cleverly combined, the lavish spirea flowers adorn the garden and balcony from spring to autumn. For your orientation we have listed the flowering times of popular species for you:

Properly cut Spiraea
Equipped with a robust pruning tolerance, you can easily keep the growth of a Spiraea under control with the secateurs. The flowering time defines the ideal time. Spring-flowering species are cut back immediately after flowering, while summer-flowering species are cut back in late winter. Don't be afraid to prune back shoots that are too long during the growing season. The incision itself follows this sequence:
Place the scissors 1-2 mm above an outward knot. Such a knot can be recognized as a slight bump under the bark. This pruning encourages the plant to branch out at this point for a bushy habit.

Water Spiraea
Although the spirea tolerates short-term drought, even soil moisture promotes growth and flowering. If the surface of the soil dries up, water the plant in the early morning or late evening. In order not to impair the flowers, you should refrain from overhead irrigation. If you cultivate the wonderfully fragrant beauty of flowers in a tub, check the moisture content of the substrate every few days with a thumb test. If the upper 2-3 cm feel dry, pour directly onto the root disc…
Properly fertilize Spiraea
A start fertilization in March/April brings the growth up to speed. Work some compost with horn shavings into the surface of the soil. Alternatively, a nitrogen-rich mineral-organic fertilizer can be used. As a result, the frugal spirea is grateful for a mulch layer of leaves, lawn clippings or compost. For a spar in the bucket, we recommend regular doses of liquid fertilizer from April to August.
hibernate
Spiraea is fully hardy and requires no overwintering precautions. Only in the year of planting do we recommend spreading a layer of leaves on the root disc, as the frost hardiness has not yet fully developed. The following measures are useful for specimens in the bucket:
Where there is enough space available, a spar in the pot moves to frost-free winter quarters. Water the plant occasionally to keep the root ball from drying out completely.
Propagate Spiraea
Spiraea seamlessly continues the long list of its convincing advantages in terms of propagation. We have compiled proven methods for you here:
