Rising Streptocarpus: Germinating Seeds
Streptocarpus seeds are among the tiniest you’ll ever sow however they’re additionally very simple to germinate for those who observe these easy directions.
Key Takeaways
- Floor sow in pots.
- Streptocarpus seed wants mild to germinate.
Sowing Seeds
One of the best ways to germinate streptocarpus seeds is to do them in a group pot. As soon as they germinate and develop to an affordable dimension they are often pricked out and potted up individually.
Take a 4 inch pot and fill it along with your favourite potting media. Pack the media down tight. Because the seeds are very small you need to stop them from settling too deep within the pot. Compacting the media helps maintain them close to the floor.
Set the pot in a tray of water and let it sit till the highest of the media is sort of moist.
Now sprinkle the seeds onto the media. Due to their small dimension, it may be tough to get even spacing. A very good approach for spreading the seeds is proven on this video:

Steered Trick: Plant just a few seeds at one time. Thirty seeds in a 4″ pot is a lot. Save the remainder of the seed for a future seeding.
Place the pot in a saggy and seal it. I do that by merely folding the highest over. A domed container additionally works. Now place the saggy in a well-lit space at room temperature and wait. Germination often begins in 7 to 12 days.
As soon as sufficient seedlings have germinated, partially open the saggy and permit some air into it. It will scale back the humidity within the bag. A number of days later, roll the bag down a bit extra. Slowly expose the seedlings to much less humidity so {that a} week later they’re uncovered to regular room humidity.
The vast majority of seedlings germinate across the 10 day mark, however some seeds will germinate over the next couple of weeks and some could take greater than a month to germinate. I’ve discovered newly germinated seed beneath flowering seedlings.
Gentle Necessities for Germination
Details about germination is sparse from each scientific circles and hobbyists.
Analysis carried out on Streptocarpus rexii discovered that seeds didn’t germinate in the dead of night and required mild for at the least 5 days to realize important germination ranges.
I discovered no details about the sunshine necessities for hybrid streptocarpus seeds, so I carried out the experiments described beneath.
Based mostly on this info it’s best to germinate seed in mild situations.

Potting Up Seedlings
Streptocarpus germinate simply however the brand new seedlings are very tiny and so they don’t develop very a lot for a few months. Then they appear to take off, comparatively talking, and if grown correctly flower in 4 to six months from seeding. An vital step is to forestall them from getting too crowded.
Take into account transferring them after the primary month. They’re nonetheless small however could be moved to bigger quarters. I choose to maneuver them to group pots the place every seedling is about 1/2″ away from its neighbors. As soon as the leaves contact it’s time to transfer them once more, both into one other group pot or into their very own pot.

As soon as the seedlings begin to develop it is very important give them fertilizer and good mild as described in Rising Streptocarpus: Gentle Circumstances.
Experiment #1: Gentle Necessities for Germination
Seeds collected from Streptocarpus RP Lacey Bloomers (see above image) had been used for these checks. Two totally different germination strategies had been used: the saggy methodology and the pot methodology.
- Dishevelled Technique. That is my normal seed germination methodology which makes use of a paper towel and saggy. The benefit of this methodology is that you would be able to visually see the seed through the full experiment. This lets you measure the time of germination and rely the % germination.
- Pot Technique. That is the strategy that’s described above in Sowing Seeds. It’s my normal methodology for very tiny seed particularly if they don’t require a stratification remedy.
Duplicates of every methodology had been ready on the identical day. One set was saved in my plant room and acquired a low stage of sunshine for about 12 hours a day. The second set was positioned in a cabinet in a darkish room subsequent to the plant room. The temperature of each rooms was very related. Apart from a couple of seconds each few days, the darkish samples had been in full darkness all day.
| Experiment Length | Germination Seeds in Gentle |
Germination Seeds in Darkish |
|---|---|---|
| Day 0 – seeding | none | none |
| Day 8 | a number of in pot, one in saggy | none |
| Day 11 | plenty of sprouts in pot and saggy | none |
| Day 27 – transfer to mild | heaps | none |
| Day 38 | heaps | heaps |
On Day 27, each the pot and saggy that had been in the dead of night had been moved to the identical mild situation because the seeds with the sunshine remedy to see if they’d germinate.
The experiment clearly exhibits that hybrid streptocarpus seed requires mild to germinate. This agrees with analysis carried out on S. rexii.
