Hi, I planted some sweet pepper seeds at the beginning of June on my south facing windowsill in pots. My first pepper started to grow last week but after about 2 days, the tip went purple. After another 2 days the whole pepper is completely purple. I also noticed that the stem and stalks have purple running through them. Any ideas what is the matter?

hi Peppery i think you may have overwatered it ow is the rest of the plant looking?

 

thank you, i did wonder about that so have not watered it for the last 3 days - the leaves have not wilted yet!  Apart from the purple running through it,it looks good I think.  There is one more tiny pepper starting which is green but has a purple tip. - the purple doesn't seem to be spreading so that's good I guess. I also repotted it about a week and a half ago with multi purpose compost which was a different kind from what it was originally in,so I'm not sure if that's affected it too?  I haven't grown anything before and saw some pepper & tomato seed pots cheap in the supermarket and thought I'd give it a go!

keep going and just water when soil looks like it needs it good luck!

Peppery, is the purple only on the stems or the leaves as well? Some peppers do have some colour in their stems. A purple tint to the leaves can mean a lack of nutrients. As budlia says, though, only water when it's needed rather than by rote. Peppers are like tomatoes, wet feet are bad for them.

hi, the purple is in the stem and runs down the central vein in some of the larger leaves but the rest of the leaf is green.  Purple seems to collect around the joints too. And the pepper is so purple it looks like an aubergine!.  And the purple is now spreading on the smaller pepper   I have about 5 plants and the others look ok, and are flowering but only one has a minute pepper on it - this looks dark green, but the purple ones started off a much paler green/yellow colour.  thanks for all the help and advice

The colour in the area where the leaves join the stem - and on the stem itself - is normal. It can be dark brown, black, purple. It's just pigmentation.

The central vein in the leaf could be the same thing. It could also mean a lack of nutrients. Have you fed it?

I've been feeding it once a week with tomorite. Here's a picture of it.

Mmmm. Far from lacking nutrients, it's probably getting too many. Once a week is too often. What variety is it? Some variegated varieties will produce colours like that.

Is that its normal position? How much light is it getting?

The trouble with being a first time grower is that I threw away the packaging after I repotted the seedlings,so I don't know what variety it is. The picture looked like the yellow and red ones you see in the supermarket.  That's not the normal position, I just moved it to take the picture.  It normally sits on the windowsill which is pretty much south facing so gets sun all day, albeit Scottish sun!

I should have asked, how often do you think it should be fed?  the bottle of feeder only really gave info about outdoor plants so I wasn't too sure...

Peppers are almost identical to tomatoess in that they do better if left to struggle a little. Tough love or controlled neglect, call it what you like. I wouldn't feed it more often than every three or four weeks.

Looking at the colour of the fruit and the amount of colour on the stems, I think it's probably a variegated variety. Variegated varieties can get very colourful.

 

Thanks so much, i will love my peppers but be tough from now on.  I am amazed - I didn't know peppers like this existed, you learn something new every day   My tomatoes seem to be doing ok- I've also been feeding them once a week and giving them much more water than the peppers.  No sign of any ripening though - do you know how long that usually takes?

Italophile

I'd lay off the water and food on the toms, too. Ripening is solely down to temperature. The fruit doesn't need direct sunlight. Optimum temps for ripening are low-20sC and higher. The lower the temps, the longer they will take. As a very very very general rule of thumb, they usually take 4-6 weeks from the time they begin to change colour from the darkest green.

Thank you for all the advice.  Low 20's is probably the highest we've had this summer and not on too many days, so I guess they'll take quite a bit longer.  I'll cut back on the water and food now.  PS the purple pepper hasn't been fed or watered all week and there's no sign of wilting and it's growing incredibly every day

Italophile

Well, there you go. Peppers - or toms, for that matter - in containers just don't need daily watering unless they're in full sun all day and it's about 35C. With feeding in containers, you only have to allow for the fact that watering will gradually leach out the nutrients you add when you feed. It doesn't happen overnight, though. It might barely happen within a week with daily watering. Even if it does, the plants need a break from nutrients. They need to cope for themselves. And they will.

Thank you, my mind is now at ease!  And the second pepper is fully purple now
