If you want to grow Hebe addenda in the garden, you must therefore ensure good winter protection in good time in autumn.
It is even better to grow this shrub veronica variety in the bucket. Then you can overwinter them frost-free indoors in winter.
Hebe addenda pull in the garden
If you want to maintain Hebe addenda in the garden, plant the perennials as early as possible in the year. Then the plants have enough time to form roots to better survive the winter.
At the latest when the temperatures outside drop to five or less degrees, mulch the soil around the shrub veronica. Cover the plants with brushwood or, even better, pine branches.
As soon as it gets warmer again in spring, remove the winter protection and slowly get the Hebe addenda used to more light again.
Hibernate shrub veronica frost-free in the bucket
If you have planted Hebe addenda in a bucket, take the container inside as soon as it gets too cold outside. Overwinter the plant in a location that meets the following requirements:
- as bright as possible
- cool at five to ten degrees
- moderately humid
Check shrub veronica for pests before overwintering.
In winter, the Hebe addenda is only watered very moderately, so that the ball of the pot just stays moist.
Get used to warmer temperatures slowly
In spring, take the ornamental shrubs out of their winter quarters and slowly get them used to warmer temperatures. Place the planter on the patio by the hour.
Tips
Hebe addenda has a very long flowering period. If you prune them right after the first bloom, you will encourage a second bloom.
