- Basement window
- Entrance area
- Corridor window
- garage
- Winter garden
- Glasshouse
Hebe armstrongii hibernate properly
The hardy Hebe armstrongii occasionally survives a very mild winter without frost temperatures. Most of the time, however, in addition to the cold, you are troubled by the high moisture in the soil.
If you want to try to overwinter Hebe armstrongii in the garden, protect the soil with a mulch cover made of lawn clippings or leaves. Cover the plants with brushwood or fir branches.
However, it is not foreseeable whether this Hebe variety will survive a winter, even if you have provided optimal winter protection.
Hebe armstrongii overwinter in the bucket
Grow Hebe armstrongii in the bucket and make sure that the plant gets enough light. If there is too little light, the leaves of the perennial turn yellow. The humidity should not be too high. Ambient temperatures between five and ten degrees at the winter location are ideal.
Water moderately so that the root ball never dries out completely. You can also fertilize Hebe every two weeks in winter.
After winter, take the perennials out of their winter quarters and slowly get used to higher temperatures. You may need to repot when the roots grow out of the top or bottom of the pot.
Tips
Hebe armstrongii can be planted very well as a border. It is increasingly used as a grave plant in cemeteries, where it replaces box hedges.
