my bell pepers are aabout six inches tall and experienced about a 2-3 hour frost. what are there chances of surviving
They will likely not survive if they are exposed to frost. You can cover them with a sheet to keep the frost off them and this will help keep them alive. This info may also be helpful:
How long until pepper seeds germinate?
You should seed the seed sprout in 7 - 14 days. The warmer they are (but not hot - less than 75F), the faster they sprout. Many people will place them on the top of appliances, like TVs or fridges as these stay just warm enough to speed up germination without overheating the seeds.
We have a chilli pepper plant that is growing inside, and I want to know when can I transplant it to a bigger container inside the house till putting outside, or should I wait till it's time to put outside?
I would wait until you put it outside. Overwintered peppers are stressed at this time of the year and repotting puts more stress on them, which can harm them. I would wait until they are placed back outside. Then they will be in active growing mode and will be better able to recover from the stress of being repotted.
In which season should red, green, and yellow peppers be planted?What is the depth that the seeds should be planted in the soil? How long do they take to grow? How much space is needed to plant the peppers?
@bluestarling says "Put plants out after your frost free date. Start seeds indoors 8 weeks before frost free date."
All colors of peppers are planted in the same way, and all green peppers eventually become red, yellow or orange peppers. This article will help you:
Can you you use seeds right out of the vegetable, like pepper seeds, tomato seeds, etc. , or do they have to be dried first?
You don't need to dry the seeds to grow them. You only need to dry them if you plan on storing them. You can plant them as soon as they come out of the fruit or vegetable.
I'm starting some pepper seeds indoors. They are beginning to grow their first set of true leaves and I was wondering when I should add nutrients.
Now would be good. They will need them once they have their first true leaves. I would use a water soluble fertilizer at half, or even quarter, strength though.
