Hardy perennials make little work for the hobby gardener. But when is the right time to plant the diverse beauties? In our post you will get the answer to this question.
Perennials are best planted in early fall
preliminary remark
Most perennials are hardy and easy to overwinter - in this respect, the information in our article applies to the majority of plants in this genus.
The ideal time for planting hardy perennials
If you are dealing with hardy perennials, it is generally best to plant them in (early) autumn - between the end of September and mid-October to be precise. The following reasons speak for this:
- Above-ground growth of the hardy perennials is already complete.
- The roots of the plants have the opportunity to grow well in the warm soil.
If, in addition, the temperatures remain nice and mild for a long time before winter comes and there is sufficient rainfall, the perennials are perfectly happy. They will then find optimal conditions to stabilize their root system and prepare for spring.
Our advice: If possible, plant your hardy perennials by mid-October. Later planting - i.e. the end of October or even the beginning of November - is not recommended. This is because the plants may not have enough time to strengthen their roots enough to survive the winter unscathed. That's why you shouldn't take any risks and don't wait too long before planting. Once the perfect moment has passed, it is better to wait until spring to plant them.
Final remarks
Basically, you can or should plant (almost) all perennials in autumn - with one exception: frost-sensitive species prefer to start life in spring.
And: Transplanting perennials also makes (more) sense in spring - from the end of March to the beginning of May.
Planting perennials themselves is relatively easy. However, you should keep a few points in mind, such as these:
- Give each species the location it prefers (sun, partial shade, shade).
- Consider the required planting distances in the bed.
- Leave your perennials without soil for as short a time as possible when planting or transplanting.
- Make sure to fertilize the plants adequately.
