How Long Does it Take to Grow a Pepper?
How long does it take to grow a pepper plant? Growing peppers is really rewarding (not to mention tasty!), but sometimes frustrating at first. Let me tell you why.
Growing Peppers From Seed
The double-trouble for how long it takes to grow a pepper plant from seed is that peppers like more warmth to germinate from seeds, and they take longer (on average) to sprout, compared to other plants (tomatoes, beans, etc.). And if you are growing the really hot varieties of peppers, you could wait up to a month before you see the little peppers starting to emerge from the ground.
Fortunately, if you get a heat mat for seed germinating, it helps a great deal. The pepper seeds appreciate the extra warmth, and they germinate a good deal faster — even the super-hot varieties. I’ve used it lots in the past, and I just got myself a new one this year.
Good rule of thumb if you plan to go the seed route; plant the pepper seeds 7 to 9 weeks before the last frost date for your area — more like 11 to 12 weeks for the super-hot peppers. And you may want to wait until your nights are consistently 55 degrees of warmer before transplanting to the garden.
Growing Peppers From Plants
If you are too late to start seeds (or just don’t feel like it) but want to grow peppers, you can get plants from your local garden center. It’s more expensive than growing from seed, but it is easier — just buy, get home and plant. Your local garden center will likely have varieties that grow well in your area.
It’s awfully tempting to buy a plant that already has peppers on it — but try not to. Otherwise, cut off the peppers before planting. Unless it’s in a large pot (at least 2 gallons), the plant is pretty stressed trying to grow with very little soil. Adding more stress from blooming and growing fruit, your pepper will be set back quite a bit.
Get a plant that looks healthy — not spindly, and not with lots of roots growing way out of the bottom (a few OK — lots, not so much).
And keep in mind…unless you have some kind of protection for your plants, don’t transplant them to the garden before the last frost date for your area. Better yet, wait until the nighttime lows are consistently 55 degrees or more.
Now It’s in the Ground — How Long Does it Take to Grow a Pepper Plant?
Assuming your weather is decent (days at least in the upper 60s, lows no lower than 55) and the plants get plenty of sunshine, you can start seeing blossoms pretty quickly — many times within a week or two from transplanting. 
As to how long before you get a pepper that is “ready-to-eat-green”, the answer is “it depends”. A sweet pepper will grow fruits much faster on average than the really hot peppers. And the warmer your climate, the faster your peppers will grow and ripen.
You’ll have to check the days to maturity for the peppers you plan to grow — it lists the days from setting out in the garden until you see the first ready-to-eat-green fruits. On average that is 65 to 75 days for sweet peppers and 75 to 90 days for the hotter peppers. And if you grow the really hot ones like habanero or bhut jolokia, you could be waiting for more than 100 days.
If you want ripe peppers — after they have turned their final color (red, orange, yellow, etc.) — be prepared to wait up to another 2 weeks.
FYI, the peppers in the photo are the variety cayenne yellow.
