Petunias are best extracted from seeds or cuttings
Just pull petunias yourself
Since petunias are usually relatively cheap to buy in garden shops, the frost-sensitive plants are usually cultivated only one year and bought new annually. If the effort of possible wintering is spared, the young plants for the new season but also be pulled yourself.
Harvest the seeds of the petunias themselves
If petunias are not grown on a covered balcony site, then they tend even more than usual to an unattractive and disease-promoting bonding of withered flowers. Therefore, it is common during the long flowering period of petunias to wilt withered individual flowers regularly. However, you should at least partially refrain from this, if you yourself want to harvest ripe and germinable seeds from the petunia. In this case, carefully remove the petals and wait until the green pistil has turned into a brown, mature and round seed capsule.
Pull petunia out of seeds yourself
Since petunias are extremely sensitive to freezing temperatures, the seeds seedlings should be brought forward on the windowsill for a vigorous start to the gardening season. To do so, sow the small seeds in pots, trays or, ideally, in a room greenhouse from February or March. You should create the following conditions:
The plants can be piqued and isolated as soon as the second leaf pair has finished developing. However, when planting in the garden or on the balcony, you should first gradually harden the sensitive plantlets in terms of temperature and direct sunlight.
Increase the petunia by cuttings
For the growing of offspring from cuttings you need some strong mother plants in spring. From these cut off about 15 centimeters long sections, from which you remove the leaves at the lower end. The cuttings rooted relatively uncomplicated in a glass of water or directly in loose Anzuchterde. Whether the rooting was successful, can be seen in the expulsion of new leaves on the shoot tips.
Tips
The cultivation of petunia from seeds is not possible without restriction for all varieties. For example, in hybrid hanging petunia from the driving trade, the typical characteristics are not inherited intact. In addition, there are also self-sterile varieties that form no germinable seeds.
