Hobby gardeners are not always once when it comes to the rock garden. Some find the natural design of a hilly landscape rather dreary, others, on the other hand, enjoy the growth of rare plants between the stones. Dwarf shrubs that expand into beautiful flower carpets over time give such a mini landscape a special character.
The stone seed (Lithodora diffusa) is recommended. It fits harmoniously into the overall composition of a lively rock garden. The dwarf shrub with its abundant number of blue-glowing flower stars is not only attractive, but also effortless to care for.
The stone seed reaches a height of just 15 to 20 centimeters and grows up bushy. The branches are overhanging and quickly cover the ground.
The leaves of the dwarf shrub are strong green and shaggy. From May to June it unfolds its glowing flower stars.
The stone seed owes its name to its ivory-colored, nut-shaped fruits. Because these are rock hard.
The dwarf shrub likes to be sheltered from the wind and warm
A wind-protected, light, partially shaded location is ideal for the dwarf shrub. A place where it receives sufficient sunlight is ideal, but not in the blazing midday sun.
The soil should be permeable and humorous
Lithodora prefers fresh, well-drained and nutrient-rich soil. The soil should also be humorous. A neutral to acidic soil is harmless.
However, avoid calcareous soil, which the stone seed cannot tolerate.
If you have a rather loamy and heavy garden soil, then work into this rich sand, gravel, humus or fine-grained bark mulch. It is important that no backwater can form at the root height of the bushy mini shrub.
If you plant a group of stone seeds, choose a distance between the dwarf shrubs of 20 to 30 centimeters. You can make the space between other shrubs or shrubs a little larger.
Water only moderately
During the time the plant takes root, water the stone seeds regularly, but only so much that the soil is moist. Later, the dwarf shrub is only watered during persistent dry periods. Do not water too vigorously and avoid waterlogging.
Use rainwater if possible. The bushy dwarf shrub reacts to chalky tap water.
Fertilization is organic
You cover the nutrient requirements with compost and organic slow-release fertilizers. You should work in compost into the soil while planting.
Before you mulch the stone seeds around the root area at the beginning of the gardening season, give the soil some slow-release fertilizer.
Divorce every 2 years after flowering
It is enough to cut back your stone seed every 2 years after flowering. This stimulates the plant to grow stronger and bushier.
A brushwood blanket for winter is advisable
The stone seed is hardy and does not need winter protection. However, it cannot be ruled out that winter will attack them in rough and snowy locations. Cover the creeping dwarf shrub with brushwood. This protects against freezing frost and retains the melt water somewhat during the snow melt.
Summary: The stone seed is an adorable dwarf shrub that causes a stir in the rock garden but also on groups of trees. It prefers a warm, sheltered location with well-drained and nutrient-rich soil. After growing, the stone seed is only moderately watered during longer dry periods. Compost and long-term organic fertilizers are sufficient for the nutrient supply.
