Petunia Seeds not sprouting

[jdashraf]

AoA. I purchased Petunia F1 seeds (4 different colours) from Awan Seeds Rwp. Sowed them as per procedure using peat moss. Its been 15 days now but none of the seeds has sprouted as yet. What could have gone wrong?

did you surface sow?
How wet did you keep your media?

No germination at all could also mean problem with seeds.

Petunias are sometimes fussy. Especially cuz they're oh-so-tiny! You should surface sow, as Farhan Bhai said. And lightly sprinkle with soil.

[jdashraf]

Yes, surface sow on top layer of peat moss (peat moss layer size of about 3/4 inch)
Kept it wet using mild spray of water (seeds were not disturbed)
Also covered the pots using plastic on top for about 10 days then removed the plastic

All other seeds have sprouted less Petunia..

Could plastic be the culprit? If there was lack of air circulation (and sunlight), then the seeds would have easily decayed and devoured by fungus.

seed sown under platic sheet should be examined frequently(daily) to check the germination. When the initial seeds start sprouting then they should be get out from the sheet to avoid the situation mentioned by Frooq Bhai.

if the peat moss layer was as thick as you said. Fungus build up will take time(if the lower media was poor)....however too wet conditions do rot seeds and very rightly pointed out that plastic should be removed on first signs of germination. If you left them without checking for 10 days..that was not desired.

I have been checking it on daily basis, there was no sign of germination..
Should I still hope they might germinate, ya fateha parh le jaae?

[Farhan Ahmed]

give it few more days. Time Span for petunia is 5-21 Days

Covering with plastic for was a complete failure. I don't know the reason but 2 times I sowed Nicotiana seed(as they are small too) with the same method and covered it with plastic transparent sheet but there was no germination but when I sowed it without plastic sheet it germinated perfectly.
