I have a few of these growing at the minute, they aren't growing very fast I have to say. Was just wondering, they are in my grow house and seem to "flop" over whenever it gets a little hot. Why is this? I thought peppers needed heat. I find myself putting the pepper plants in the shade just to get them looking healthy again and not drooping over.


Any help/advice/tips...

I am far from expert, but logic tells me if they look healthier in the shade.......leave them there.

Others may shoot me down tho.


How hot does it get in the greenhouse, Scott? Excessive heat will flatten the plants. Make sure there's plenty of ventilation.

Not sure how hot it gets, it can't be that hot as I have the door zipped right open and tied at the top, so basically it's open all the time. It's just a plastic grow house.


What size pots are they in and how big are the plants?



Scoot, it sounds like a heat issue. Plastic magnifies heat even if the door is zipped open. Dove's question is a good one, too. If the pots are small, they will suffer more - and quicker - than in larger pots.

My greenhouse is one that zips open at the front, and like yourself I'm leaving it open all the time, however my thermometer regularly reads over 30 degrees on a sunny day. It really has surprised me how hot they can get.

If a sunny, reasonably warm day is forecast, it wouldn't hurt to put the plants outside. Leggi's temp reading is par for the course.

I am having a similar problem with mine but mins are outside all the time, 2 of my pepper plants have died and i only have one left which i don't think will last long either

here is a tip hun, in the morning water the floor of ur pop up green house, this will humidify ur green house, which is what this plant needs, water in the air! sadly ur tomatoes if u have any, wont like it lol


The Kitchen gardener

it wont kill ur tomatoes ofc, but they will produce slower, but humidity is what is needed here and too much air will also send them into deflate statis, so don't leave the door open, open for a few hrs at a time only, needed for pollination ofc, but the plants hate the cold, and dips in temp will cause them to wilt

remember where ur plants orginate from, and try to marry there condictions to there nature climate! then u have a plant that loves you!

The Kitchen gardener

also a tip to check ur pot sizing, ur average pepper needs a pretty massive pot to survive, so make sure if its 2 foot tall or over to plant it in the ground (in the green house)  rather than a pot, if u need a pot, go for the biggest u can get, there roots are awesome! think the size of ur catering pot, not sure what that is, but would hold 3 bags of spuds, pretty damned big!



The Kitchen gardener

watch his other clips on how to raise them, best advise on the net tbh


in these temperatures my potted sweet peppers and chili peppers are all outside on my patio in the sun, once the night time temps start dropping below 12 degrees that's when they'll go back in the greenhouse, plus they get pollinated better outside!

I had mine in a blowaway and they were covered in white fly - both sweet peppers and chilli's. So I threw caution to the wind and planted them outside in our veggie patch - that was about a month ago and they are going great, fingers crossed they stay that way, lots of peppers and chilli's, just waiting for them to ripen now - any tips on speeding that up!?


Just watched the youtube link recommended by Kitchen Gardener. Novel way to treat peppers. I will be giving it a go. Well worth a watch!

Right now it's so hot I would put them outside!!
