All there is to know about growing rhodanthe…
Planting and sowing rhodanthe
In spring, as early as mid-March in mild climates or April in northerly regions.
- Choose a location that is well exposed to the sun but not scorching.
- After having sown the seeds, water regularly to ensure that the soil remains damp.
- Once seedlings have sprouted well, you may thin them to give breathing space to your young plants. This means removing those sprouts which are too weak and too crowded together.
Just like the aster, ordinary soil mixed with a bit of soil mix is perfect, because the soil must drain well.
- Avoid compact and heavy soils that would retain water instead of releasing it to the plant.
- To nicely cover a surface, plant around 8 or 9 flowers to a square yard (1 m²).
Pruning and caring for Rhodanthe
Very easy to grow, rhodanthe only needs very little care.
If you wish, deadheading is possible – snipping off wilted flowers – in order to spur appearance of new flowers, but new flowers would still bloom even if this isn’t done.
Rhodanthe is sensitive to frost and will only grow back year after year in regions with mild winters. Spontaneous growth from seeds does occur regularly, and some plants that had died off in winter may grow again in spring.
All there is to know about Rhodanthe
A plant for flower beds, edges or rocky land, rhodanthe is spectacular from spring to fall thanks to its generous blooming which constantly renews itself.
Rhodanthe is also called pink immortal, a name that comes from the fact that its flower when picked and dried holds perfectly all winter long, staying very ornamental all along.
Remember lastly that rhodanthe is one of the easiest flowers to grow, but also is one of those bearing the most flowers from spring to fall.
Smart tip about Rhodanthe
Rhodanthe fears strong summer heat waves that often lead to the appearance of powdery mildew.
If you are in a region where summer is scorching, it is better to favor partly shaded areas.
