Ornamental shrubs - care and cutting Ornamental shrubs are particularly popular with amateur gardeners, because they beautify the garden with its loose growth and flower splendor. They are comparatively easy to care for. They are not very susceptible to disease and usually can hibernate outside as well. A distinction is made between summer and evergreen ornamental shrubs, with the best-known species being roses, rhododendron, jasmine and cherry laurel.
Suitable seasons for planting ornamental shrubs are spring and autumn because the trees are at rest at the beginning or end of the growth phase and grow best. In addition, threatened at this time no frost damage and no drying out of the roots by prolonged summer heat. These steps are to be considered when planting:
- First place the shrub in a bucket of water to allow the roots to soak
- dig out a sufficiently large planting hole, at least 40 to 50 cm
- Put the shrub into the hole and fill it halfway with soil
- Water the planting hole thoroughly and then fill it up with soil
- press in the end, but not too strong
Ornamental shrubs love a loose to crumbly soil structure, compacted soil is unsuitable. The soil should be humid, but waterlogging should be avoided. In very dense and loamy soil conditions, experts advise mixing the soil with garden soil or replacing it entirely with garden soil. Depending on the species some ornamental shrubs have special preferences:
- Rhododendrons love humus, peat or peat substitute
- Lilac and Eisenhut like calcareous soils
A large part of the ornamental shrubs loves sunny or partially shaded locations. However, there are also species that feel comfortable in the shade. When selecting the location, it should also be noted how frost hardy the respective woody plants are. How to choose the right place for your ornamental shrub:
- Cherry laurel is originally from the Black Sea and is not unlimited hardy, it needs a sheltered location
- Roses feel most comfortable in sunny and breezy places, but do not like direct midday sun
- Forsythia loves it half shady to sunny
- Lilac likes it half shady to sunny
- Rhododendron also feels in very shady places, eg. B. under trees, well
Most ornamental shrubs are considered winter-proof, and many exotic shrubs can tolerate a certain amount of frost. Especially in recent years, however, extremely cold winters with very extensive frost periods have increased more and more. Therefore, it is advisable to cover the soil around the shrubs with materials such as straw, bark or wood wool. This also helps against the so-called freeze-drying, under which many plants suffer from dried out by sun and frost ground. Some ornamental shrubs need a special winter protection, which differs depending on the species:
- cover the basal shoots with spruce branches at Rosen and pile the knotty base with bark mulch
- Shade cherry laurel and rhododendron with nets or garden flow
- Cover lilac about 20 cm high at the root base with leaves or straw
Ornamental shrubs are usually fertilized in spring, when the growing season begins and the nutrient requirement is greatest. Suitable are organic fertilizers and compost. Work the fertilizer loosely and evenly into the soil. Ornamental shrubs should be watered regularly, taking care that the soil is neither too dry nor too wet. Especially in the hot summer months more frequent watering is necessary. To avoid freezing in winter, you can cast on frost-free days.
Most ornamental shrubs require a regular pruning, usually every 1 to 2 years, to ensure a vigorous renewal and / or wealth of flowers and fruits. In order to prevent damage from snow load and wind break, an autumn cut can be made on certain shrubs where weak shoots are removed. However, the actual pruning takes place in February or March on frost-free days. Ornamental shrubs that bloom in summer are radically cut back to about 50 cm to 20 cm above the ground, thus a particularly lush new shoot can be achieved. Spring flowering shrubs should receive only one clearing cut in February / March, removing dead, sick and weak shoots. Correctly cut back after they bloom. You should also be aware of this when cutting ornamental shrubs:
- Species such as magnolias, laburnum, and witch hazel only in an emergency and crop only the most urgent tricks because they are difficult to regenerate
- Shortening of very long young shoots always about 5 mm above the bud with a slightly oblique cut to keep the wound as small as possible
- Repair frost damage only in spring, since the extent of damage only becomes visible after budding
- when removing sick and frost-damaged shoots, cut deep into healthy wood
- remove weak shoots to the base
- Roses and jasmine are often attacked by aphids that effectively fight you with organic sprays
- A typical pest for rhododendron is the rhododendron cicada, which is attracted by and sticks to yellow shrubs hung in the shrub
- Magnolias are often plagued by pests such as the white fly, whereas insecticides help
- Cherry laurel is very susceptible to fungal infestations like powdery mildew and downy mildew, infested leaves must be completely removed
- Also laburnum is prone to fungal diseases, infested shoots are cut off at least 15 cm below the diseased area
Most ornamental shrubs thrive very well in our latitudes and are considered with their flowers or their fruit decoration as an asset to the garden. With careful care, the appropriate measures for hibernation and the observance of some rules when cutting you can enjoy for many years healthy and lush ornamental shrubs.
An ornamental shrub is placed at the planting in a bucket of water, where its roots are made with water. While the roots provide water, a suitable approximately 40 to 50 centimeters large plant hole should be dug for the ornamental shrub, but the soil must be loose.
The ornamental shrub is now placed in the plant hole and the hole is filled up to half with soil. Now water is poured on it, added more soil and pressed to the end. When the transplantation is finished, the ornamental shrub must be continuously poured.
Ornamental shrubs should be fertilized in the spring with organic fertilizer such as compost which is loosely incorporated. If weeds appear, it is best to remove them by hand or shovel, taking care not to damage the ornamental shrub.
The cut occurs in ornamental shrubs that bloom already in spring, after flowering. Summer bloomers get their cut in spring, about April. You cut from the inside out and from bottom to top. First remove dead branches and branches that are near the ground and then cut the plant inside. They make it something like that; however, only about a quarter of the plant should be removed. The less blended, the less wild shoots drive out.
On ornamental shrubs there are the firethorn, laurel cherry, gold finger, beauty fruit, carpet berry, winter flower, beard flower, peasant jasmine, English heather, ornamental cherry, silver shrub, Florence magnolia, star magnolia, plate hydrangea, scented blossom and more.
