Flowers in the right place
In order for the lupine to be able to produce many flowers, it needs sun. This applies to outdoor plants as well as to lupins in pots. A favorable location should offer these conditions:
- As sunny as possible
- Sheltered from the wind but airy
- Loose soil
- No waterlogging
- Beautify the terrace with lupins in a pot
- Yellow, white and blue lupins - protein sources of the future
- Planting lupins in the garden or in a pot - tips and tricks
Lupins also thrive in partial shade, but then stay small. Make sure that the plants are exposed to direct sunlight for at least three hours a day.
Demands on the soil
Lupins are soil improvers and are therefore also used for green manure. The ornamental plants can even cope with compacted soil, because the long roots penetrate almost any substrate.
If the soil is nice and loose and a bit sandy, the lupine thrives particularly well. Mix in some sand in hard soils so that the perennial grows denser and forms more flowers.
The lupine does not tolerate waterlogging. Irrigation and rainwater should be able to drain off.
Do not plant too densely
Keep a distance of 50 centimeters when planting in the garden. Then the air can circulate between the leaves. This prevents powdery mildew from occurring and protects against viral infections.
Tips & Tricks
If you cannot offer the lupine a place that is really sheltered from the wind, protect the flower panicles from kinking. Tie them to support posts or buy special planting racks that give the stems enough support even when there is a draft.
