Sternmoos is a small, uncomplicated upholstery perennial, which looks great in the rock garden, but can also be used for planting graves or as a lawn replacement. The plants are easy to care for and hardy. Sternmoos is native to Central Europe and therefore well adapted to our climate. If you take into account the location conditions and soil requirements of the plant, you will be able to observe the growth and prosperity of the pretty rock garden plant. You can now read about what should be considered when planting star moss.

Plant Description

Even if the star moss forms a pretty moss lawn, botanically speaking it is actually a clove family. The star-shaped small flowers and the moss-like appearance gave Sagina subulata its name. As a representative of the fattening herbs, the star moss is characterized by herbaceous growth. The leaves are only slightly upright. The growth height hardly exceeds four centimeters, but dense grass carpets are created and the plant quickly grows in width.


The small white flower heads appear in late spring. The bright peel flowers form a nice contrast to the light green foliage. The flowers sit on the short stems and appear extremely numerous even in a shady location. The flowering period extends into late summer.


The uncomplicated star moss can be used in many ways in the garden. Smaller upholstery upgrades the rock garden. In the immediate vicinity of hornwort, low bluebells or chamomile, a pretty and colorful picture is created. Dry stone walls can also be planted with star moss. The plant also thrives between pavement slabs and can be used to green roofs.

" Tip: Star moss is also suitable as a lawn replacement.

It often happens that the lawn does not grow densely in shady areas or even has visible gaps. Sowing lawns is often difficult even on rough slopes. Sternmoos offers a welcome replacement here. You can even save yourself from mowing the lawn later. Star moss does not grow taller than five centimeters.

" Tip: The star moss is also decorative and easy to care for as an underplant for flower boxes and plant trays.

Find the right location

The hobby gardener is flexible when choosing a location. As one of the few plants, the clove family also thrives in the shade without any problems. In a sunny location, frequent watering is necessary. Especially in hot summers there is a great risk that the upholstery will dry up. Two hours of sunshine a day are considered optimal for the heat-loving plant. The Sternmoos does not get a location that is too dry or too cold. Furthermore, the plant does not feel comfortable in competition with lush weeds such as white clover, cinquefoil or white plantain and grows rather poorly.

→ in a nutshell:

  • very adaptable to the different locations
  • two hours of sunshine a day are sufficient
  • in a full sun location high fluid requirements
  • reduced growth in dry locations
  • existing weeds hinder the growth of the plant

Choose the ideal substrate

The plants are somewhat more demanding in terms of location. The floor should well permeable be to the Danger of waterlogging to minimize. Heavy clay soils should enriched with sand become. The roots quickly start to rot if the substrate appears too dense. The floor should wet, but by no means be too wet. The pH should be in a neutral to slightly acidic environment.

Planting instructions

1. Select location
2. Prepare the soil
3. Dig out the planting hole
4. Maintain planting distances
5. Insert the plant
6. Close the planting hole
7. Press the earth down well
8. Water the plant

After choosing the right location, the soil must be prepared for planting. The substrate should be loosened and free of roots, stones and weeds.

" Tip: The Sternmoos does not tolerate weeds in the surrounding area.

Heavy soils should be loosened well and made more permeable with sand. If you want to create larger upholstery, you have to pay attention to the appropriate planting distance. So that there is a dense moss lawn in the foreseeable future, the planting distance should not exceed 15 centimeters. When planting in the rock garden, care must also be taken to ensure that it is unique. A planting distance of 20 to 30 centimeters is shown here. Because the upholstery perennial grows very quickly. After planting, the star moss is to be watered on well.

Plant star moss in a bucket

The container planting is ideal for the design of plant trays or the underplanting of tall stems cultivated in planters. The care required increases by planting in the bucket. The plants there often have little substrate available. Therefore, the star moss can only absorb a minimum amount of water and nutrients via the roots. If the small cushions are to grow abundantly and develop many flowers, water and fertilize regularly. If the planting bowl is set up in a sunny position, it may be necessary to water the star moss in the morning and evening in summer. Failure to do so may result in the plant drying out almost overnight.

The peculiarities of container planting in brief:

  • low fluid and nutrient supply
  • frequent watering necessary
  • Feed regularly during the growth phase
  • Protection during the winter is necessary

Overview of planting star moss

Find locationThe plant thrives in any location. Partial shade with a few hours of sunshine turns out to be ideal. The plant does not need more than two hours of sun a day. A too sunny location quickly leads to drying out of the plant with insufficient watering.
Prepare the substrateSince the star moss does not tolerate waterlogging, permeable soil is particularly important. The plant grows poorly in heavy clay soils. The nutritional requirement is rather moderate. Compost provides valuable natural fertilizers.
Plant star mossWeeds should be removed generously before planting. About twelve young plants can be used per square meter. There should be at least ten centimeters of planting space between the individual plants.

Transplant star moss

If the Sternmoos is to be transplanted, spring and autumn are the ideal times. The roots grow rather poorly. This has an adverse effect on transplanting in the heat or when there is a risk of frost. If transplanted in summer, there is a high risk that the delicate roots will dry up. When transplanting in late autumn, it can happen that the plants no longer grow sufficiently and thus lose the ability to spend the winter unscathed.

A warm but cloudy day should be selected for transplanting. The plants must be carefully lifted from the ground and pricked over a large area so that the roots are not damaged. After planting out, the star moss should be quickly put into the ground at its new location.

" Tip: Transplanting offers a good opportunity to check the roots of their texture and to divide the plants if necessary.
