Unless particularly sensitive plants are involved, they will thrive even in the rock garden. Many alpine plants, however, also require very special conditions for cultivation and must be produced beforehand Rainfall be protected. Last but not least, some demanding and very rare species are much more successful when grown in the greenhouse than outdoors.

The ideal alpine house
The best living conditions for the plants can be achieved with underground greenhouses. However, tufted bells, devil's claws, hunger flowers and snow pathways love particularly light-flooded raised beds, so that one Greenhouse wall height of 60 to 80 cm is optimal were. Single glazing is suitable for rearing purposes, and in winter the north side should be insulated with additional bubble wrap. However, large temperature fluctuations between day and night must be compensated for by a heating and ventilation system. In an emergency, you can also use straw mats.
Colorful variety with orchids, grasses and trees
Pretty much all plants that exist in the world, especially in the high mountains, can be grown in the greenhouse. Here are some examples:
| Plant species | Heyday | colour | Height (cm) |
|---|---|---|---|
| anemone | February to May | white, red, purple, pink | approx. 10 to 30 |
| Trefoil | March to April | White | approx. 5 to 12 |
| Knot flower | September to October | White | Max. until about. 20 |
| Stone purse | May to July | purple, white, pink | approx. 5 |
| gentian | May to June | blue | approx. 10 |
| Edelweiss | June to August | white-gray | approx. 20 |
| Sedum plant | June to July | yellow | approx. 5 to 10 |
| jasmine | May to June | yellow | approx. 30 to 40 |
Requirements of the plants
Depending on the variety, you can grow most of the alpine plants directly in the ground from the greenhouse (ideal pH value around 6) or leave them in a pot that is put in a mixture of sand and peat. Otherwise only that which is collected is clean Rainwater for irrigation needed. From time to time, alpine plants should be repotted, whereby it must be ensured that the sensitive root ball remains undamaged with the soil. Dead plant parts are removed at the same time.
The irrigation of alpine vegetation
Excessive watering or even waterlogging must be avoided at all costs. The direct water jet from the hose, too, so as not to damage the sensitive plants. During the Moderate watering is sufficient in the winter monthswhich can be supplemented with a fertilizer until August. The liquid fertilizer is simply added to the irrigation water in the lowest possible concentration.
Tips
If you grow these uniquely beautiful plants in the greenhouse, they will thrive best in summer under the protection of a movable outer shade that can be rolled out and rolled up when necessary.
