The seeds of asters taken under the microscope
They are available in white, deep blue, pink, purple, red and even yellow flowers - the asters. Depending on the variety, they inspire with their charm. One aspect in which they are all quite similar are their seeds.
How do you look like?
Not everyone has ever seen the rather inconspicuous and - admittedly - less spectacular-looking seeds of the asters. To recognize them, once in the garden, when you walk past the withered flowers in the garden and are perhaps looking for seeds for spring planting, you should know their external characteristics.
This is how the seeds of the asters look like:
Seed maturity: Different from species and species
In the aster-world there are those species that already bloom in May. Others bloom in midsummer and some only in autumn. Due to the different flowering time results in a different time of seed maturity. This is how the seeds of spring asters mature in July. The seeds of autumn asters are not mature until late autumn.
What should one know about the germination or sowing of the seeds?
The seeds can be brought forward between March and April. Direct sowing in the field should not be tackled before May. Even at temperatures around 10 ° C germinate the seeds. But the higher the temperatures, the faster they germinate. Their average germination time is between 7 and 14 days.
Harvest or buy seeds
You can easily reap the seeds. But beware: Some seeds like those of the Alpine Aster need a cold stimulus to germinate. If you decide to buy the seeds, you usually do not need to expose them to cold. This has usually already been done.
Tips
If you've harvested the seeds in the summer or fall, it's best to keep them in the fridge until next spring. So they keep their germination ability.
