Growing hibiscus from seeds is – from my point of view – one of the most rewarding experiences one can achieve. It can last from 6 months to 3 years to see the first flower of a hibiscus born from your own two hands 🙂
As Mrs. Monica Trusca was so kind to share her pictures of the process, I made a two part article to show it.
I think that first of all everyone must try to provide the seedlings the most appropriate conditions for growing and flowering, even if we live in a less friendly environment for hibiscus.
First of all, we must use VERY FRESH seeds. It is essential.
Here are the seeds freshly harvested from their pods:
We can see the mature seeds ripening from the seed pods. After taking them out, every tiny seed must be scarified on the bellied end. That means we must take a sharp knife or a cutter and remove the tiniest part of the black coat that covers the white embryo. This procedure is necessary in order to let the moisture get to the embryo and make it sprout. The seeds must look like this:
Seeds are placed on a wet paper towel treated with a substance such as Previcur from Bayer.
The seeds are then placed in a propagator (ideal situation) or in a lid box (less than ideal) in order to keep the humidity inside and help them germinate quickly. To obtain this, the temperature inside the germination box must be 22 Celsius or more.
The germinated seeds after 2 days
The tiny embryos must then be cleared from the black coats, because these can get mildew and kill the tiny plants. During this process, we must spray the seeds once or twice with a DILUTED substance of antifungal agent.
After 4-5 days, the plantlets can be transplanted for the first time into substrate, keeping in mind that they still need a lot of humidity to grow. Try to cover the plantlets with a lid or a transparent bag and ventilate them several times a day while keeping the temperature at 22 Celsius.
Evolution: seedlings have 14 days and we can start and feed them with a VERY diluted solution of Hibiscus Feed.
Evolution: seedlings have 30 days 🙂
30 days seedling individually transplanted for the first time.
Several generations of Hibiscus seedlings – from 30 to 60 days.
The second part of this article will show the plants from 60 days to flowering size 🙂
Have a nice week all!
