- It has been a very hot start to the week in the UK with temperatures exceeding 40c in some parts of the country. In this video, I'll be showing you how I protected my plants in the greenhouse from the intense summer sun. I also recorded a time lapse of the thermometer rising in the greenhouse during Monday and Tuesday, although this turned out not to be a good idea! Enjoy! :)

reporting from northeast Ohio. My high in my plant room is 30C, low is 27.7C. Current outdoor temp is 31C. predicted high temps over the next ten days range from 27C to32C. Lows range from 19C to 22C. This has been a fairly mild summer for this area. Normal highs for this area at this time of year range from 32C to 35C. I live in a sixth-floor apartment in a high-rise built on high ground, so I get good air circulation in my plant room just by opening a window. I close it only when it is raining.
One thing to watch closely in a heat wave is the nighttime lows. Cam plants cannot breathe during extreme heat because their stomata close to conserve moisture. This means that the plant converts all its CO2 to oxygen sometime during the early afternoon. With no CO2, Photosynthesis cannot occur. If temperatures drop significantly at night, the stomata open, oxygen escapes and the plant can absorb enough CO2 to perform photosynthesis again in the morning. But if the nighttime temperatures do not drop, the plant uses up its CO2 on the first day and cannot get more until the temperatures drop and the stomata open again. Watering is not necessary at this time because, with the stomata closed, no water is lost, and the plant cannot grow without the carbohydrates produced by photosynthesis.
One piece of data I have not been able to find is at what temperature the stomata close and open. All the articles say they open at low temps and close at high temps, but none of them say how low and how high. My guess would be somewhere between 24 and 30C. If anyone has a more accurate number, I would like to hear it.
Thank you for your detailed comment, Emmit. Definitely deserves a pin. I think with CAM it can be different between species. I did see a graph showing what time the stomata on an Opuntia opened but nothing on what the temperature was during that time. Would be nice to know exactly what the temperature ranges are for different plants, but I don’t think any detailed studies have been done on it with cacti and succulents, unless we’re just not looking hard enough lol. Thank you for watching and commenting 👍🏻🌵☀️🌼🌺🏜
Hot hot hot!!...melted camera hot lol
Haha yeah, definitely wasn’t a good idea 😂 Cheers for watching and commenting mate 👍🏻🌵☀️🌼🏜
Stay safe sir
Thank you, will do 😊 Thanks for watching and commenting 🌵☀️🌼🌺🏜
Nice sharing po
I will share to my mommy
Maraming salamat po sa comment at sa panonood 🌵☀️🌼🌺🏜
We had 33 degrees on Gotland in Sweden, that is hot for us!
That is! Thankfully it has cooled off now. Thanks for watching and commenting 🌵☀️🌺🌼🏜
Welcome to my summer! 😉 But yours is different because your humidity is high. That makes it more uncomfortable for you and “feel factor” is also hotter. But you did great at protecting your plants in the greenhouse. Not so great at protecting your camera 📸 🤦🏻♀️😆Thank you so much for mentioning my channel. Ugh, I need a new banner. 🤣 I hope your weather is better now. Stay hydrated!
Thank you so much, Ana ☺ Apparently the humidity was pretty low on both days, around 15-20% according to my app, but of course at night that went up and made for two very uncomfortable nights sleeping. We have no aircon here either unfortunately. Haha I wont be putting the camera in there again that's for sure! Nothing wrong with your banner ☺ thank you for watching and commenting as always, Ana. Have a wonderful day from Edith & myself 🌵☀🌼🌺🏜☕
All your cacti are looking so happy and healthy.I think they love where they are and the warm weather.
Thank you so much, Rhea 😊 Was a little too hot for me though lol, especially at night, very oppressive. Thank you for watching and commenting, have a wonderful evening and weekend from Edith & myself 🌵☀️🌼🌸🌺🏜
Waahhhh super hot like Philippines and I don’t like that heat 🥵 glad it’s over now. Nice to see the plants in the greenhouse and great job protecting them. Lovely flowers too. It’s raining here now. Take care Daz and Edith and hope you having a great day. 🌵💚
It was too hot here on those two days 🥵 We’ve had no rain here for a month now, we’re pretty desperate for it and I need some to fill my water barrel up again, it’s almost empty 😬 Thank you for watching and commenting as always, Kath. Have a wonderful day and weekend from Edith & myself to you and Phil 🌵☀️🌼🌸🌺🏜
That heatwave was very hot! My greenhouse got into the 50s celsius and it was 40c outside, all my plants survived and I hope you had no losses too
Too hot. I think without the 90% shade netting it would have probably reached close to 50c. An Aloe and a Euphorbia got a little scorched on some new growth, but nothing they won’t recover from. Thanks for watching and commenting 🌵☀️🌼🌺🏜
WOW this is a really BRILLIANT video Daz :-D you have done an amazing job of protecting all your plants during the heatwave and the thermometer time lapse was absolutely AWESOME, this Summer has been crazy hot in Ireland but its been so much hotter for you in England than here, on Monday it reached 34c in our back yard although it was 27c in our front garden, the polytunnel reached 48c and we was so worried the cover would melt as the metal poles were red hot to touch, but I can only imagine how much hotter it would have reached in the polytunnel if we had had the temps you have had, argh haha, well done on protecting all of your beauties in the greenhouse and all your plants are looking AMAZING, thanks so much for sharing this awesome vid Daz, and Hans and I are sending you and beautiful Edith lots of love and happiness and PLANT POWER to England and Singapore for a super cool afternoon and evening ahead XXXXX
Thank you so much, Lyn 😊 Yeah it was certainly a very hot two days, although the nighttime temperatures were unbearable, couldn’t sleep well at all. I think the temperature in the greenhouse would have been higher without the 90% shade netting, glad I bought that. Oh yes the frame on the greenhouse was red hot, but not as hot as the paving slabs, could fry an egg on those 😂 Thank you for watching and commenting as always, Lyn. Have a wonderful day and weekend from Edith & myself to you and Hans ❤️🌵☀️🌼🌸🌺🏜
@@Cactimania XXXXX :-D
It was 108degrees farenheit in Oklahoma City around that time
Hot here again today but not as hot as it was on those two days. Thanks for watching and commenting 🌵☀️🌼🌺🏜
Heat advisory this week and last it’s been 100+ I have my rainbow and old man cactus outside, so far they are toughing it out. I’m in the middle of the USA, good old Kansas! Your green house and cactus are amazing! I love your channel/posts. So helpful!
Yeah I’ve seen you’re experiencing very hot weather there. Thank you for watching and commenting, glad you enjoy the channel and videos 😊🌵☀️🌼🌺🏜
Living near the equator, I am so used to very warm temperatures but I cannot remember ever experiencing that kind of heat, Sweetheart. Ghastly really! That shade netting is perfect. If your thermometer was placed without that netting, your reading would’ve probably reached 50c or more! 🥵😱 I am thankful that you are safe there and the temperature has improved a bit. Hopefully, you can sleep much better tonight. ❤️
Very ghastly lol. Last night was absolutely unbearable, couldn’t sleep very well at all. Oh yes the reading would have been higher without that netting, definitely. It was them scorching I was most worried about but the netting definitely protected them. Feels more humid today and I think tonight is going to be another uncomfortable one 🥵 Thank you as always babe for all your love, support and encouragement ❤️🌵☀️🤗😘❤️

Omg! You're having my usual temperature 🥵🌡️! Here at Valencia, Spain we are experiencing the hottest summer ever. Right now we are over 30 Celsius most of the day, reaching 45 in my covered area, just a few hours in the middle of the night down to 25°C, tropical nights for a month and a half, over 20°C in June and over 30°C in July (high humidity of the Mediterranean coast makes it really uncomfortable). I had to give shade to my plants that are totally dormant now and I had a few cacti burnt under a shade of 40% protection🙈 ... some baby Echeverias got cooked (that happens to me but not so many as this year). And we are having a lot of fire in our forests here in Spain 😩... Crazy! So sorry for your camera 😳, I can't use my mobile outside without a shade, most of the day due to overheating. Good luck with your plants, hope they resist 🤞😘💞
Thank you so much, Vanesa 😊 Yeah I’ve seen the crazy hot weather and the fires there, it’s awful ☹️ We had fires here on Tuesday as well but nothing on that scale. I know what you mean about the tropical nights, it was absolutely unbearable on Tuesday night, couldn’t sleep at all. Temperatures here are much cooler now but they’re going up into the 30s again at the weekend 🥵 Thank you for watching and commenting, Vanesa. Stay safe in the heat from Edith & myself 🌵☀️🌼🌸🌺🏜
@@Cactimania Oh, so sorry to hear that you had fires also where you live🥺🙏. Yeah, sleeping with high temperature is a true nightmare🙈, we kind of solve that in Spain with our 'siesta' (sleeping twenty minutes or so after our lunch between two and three pm) but it's difficult to find that pause if you're working and we end up being really tired after a few weeks of hot nights 🙈. Thank you for always answering my comments. Lots of kisses to Edith and you 😘
Great video Daz! It’s Uncustomary heat everywhere🥵happy your plants are surviving the heatwave.You have a fantastic collection! It’s about 109F where I am in Texas. It’s a dry heat and it feels like your skin is on🔥fire. You and Edith have a great week ahead🤍🌺🍃🌳🌿🌵🪴
Thank you so much, Forsythia 😊 Yeah it was pretty unbearable here for those two days, and especially at night, very difficult sleeping conditions and we don’t have aircon here 🥵 Hope it cool down there a bit soon as well. Thank you for watching and commenting, have a wonderful day and week from Edith & myself 🌵☀️🌼🌸🌺🏜
Great video! Very helpful.
Wishing you and Edith a wonderful week!
The temperatures even in my area have been absolutely insane. 🌵☀️🌸
Thank you so much, Henry. Was another hot day here yesterday, but not to the extreme of the previous week. Hope we don’t get temperatures like this again this year, but we still got August to get through 😬 Thanks for watching and commenting, have a wonderful day and new week from Edith & myself 🌵☀️🌼🌺🏜
I hope all your plants made it though the heat wave. Its about 34C here this week which is pretty typical for my area. I'm happy when its below 38C 😀 I've also had a camera decide to turn itself off in the heat. So disappointing to loose the footage but at least it made a good story! I hope you and Edith are enjoying the summer and don't forget the sunscreen. 🌞
Thank you so much, David 😊 Plants seem fine, heat didn’t bother some and probably enjoyed it as they flowered. I won’t be putting the camera in there again that’s for sure lol. Cooled down here significantly now but temperatures are meant to rise again at the weekend. Thank you for watching and commenting, have a wonderful day from Edith & myself 🌵☀️🌼🌺🌸🏜
Hi! I hadn't put any of my succulents out on our deck because we're painting. I do have others outside and it's currently 96° F on the deck. Expected to reach almost 100 this weekend. Very unusual for us in this part of Northern US. Crazy weather! Stay cool and all the best wishes for your plants to be ok!
Thank you so much, Molly 😊 It’s cooled right down here now, much more comfortable. But temperatures are meant to rise again at the weekend but not to the extremes of Monday and Tuesday thankfully. Thank you for watching and commenting, have a wonderful day from Edith & myself 🌵☀️🌼🌸🌺🏜
Very hot here on the coast in Essex too, reaching 35 deg C or so. My cacti are all outside at this point, so I've not had too much of a problem with scorching. It's very counter-intuitive resisting the urge to water though, I'm going to try and hold off till the weekend at least.
Thanks for another nice video!
Thank you, David. Yeah I won’t water any yet either, but it’s meant to get hot at the weekend once again, great! Thank you for watching and commenting, have a wonderful evening from Edith & myself 🌵🌼☀️🌺🏜
God advice Daz that was much Needed yesterday,
It's ten degrees cooler here today,so back to normal
For us in Essex,all's well that ends well,Bill.
Doesn’t really feel any cooler here today lol, feels like the humidity has gone up more. Might get hot again at the weekend, wonderful! 🥵 Thank you for watching and commenting, have a wonderful, and cooler evening from Edith & myself 🌵☀️🌸🌼🌺🏜
We had some very high temperatures this month too in Poland, I thiink it was 36 C? Suprisingly lower than you. I only felt some of it in the garden in the morning when we watered all the plants that needed it, and I promptly hid inside because it was terrible. Having a ground floor room is good for summer, hah... it's nice here and not hot at all. Bless the insulation, all the neighbours above me and the cold seeping in from the basements below. The tradeoff is I do have the coldest room in the winter too, but I think I prefer to dress up a bit in winter over melting.
Oh I definitely prefer the cooler temps, it’s easier to warm up in the winter than it is to cool down in the summer that’s for sure! I don’t mind the heat it’s just the nighttime temperatures here have been unbearable. Heavily insulated houses it takes time for all that heat to dissipate. Thanks for watching and commenting 🌵☀️🌼🌺🏜
Hello from across the Atlantic - USA. Here in the suburbs of Boston MA the heat is also dialed up around 95F for the week. My succulent seem ok on the railings of a tree-shaded deck and a covered balcony. I think they are doing better than me! Love your channel… TYVM!
Thank you 😊 Glad your succulents are doing fine despite the heat. I’m just concerned what August might bring, can be pretty hot here during that time as well. Thanks for watching and commenting 🌵☀️🌼🌺🏜
You did a good job keeping the cacti cool👍It's been roasting as usual here in Japan. I actually don't water my plants in July or August. I may spritz them if we get a rainy week. My cacti are on big tall stainless shelves and shade cloth is up from late April. Thanks for your detailed video👏It was very helpful
Thank you so much, Newman 😊 Yeah I heard it’s been very hot there, too. It’s cooled down here now but temperatures set to rise again at the weekend, although not as high as the recent temperatures thankfully. Thank you for watching and commenting, have a wonderful day from Edith & myself 🌵☀️🌼🌸🌺🏜
Yes, Hopefully not as hot this weekend🙏Take care
I read that this is really a record for the entire history of observations. So all kidding aside, hang in there Daz, it's super hot.
Thank you so much, Serge. Yeah lots of places experiencing weather extremes, these sort of temperatures will probably be a more common occurrence very soon. Thank you for watching and commenting my friend, have a wonderful day from Edith & myself 🌵☀️🌼🎶💛💙
I love the dramatic music with the time lapse footage, I can feel the heat rising! Unfortunately I'm here in Las Vegas like Anna and I just got back from vacation and I've had several plants lost because of extreme sunburn and rotting (I had a friend come water while I was away). Current temperature is 110F. It was still 100 degrees at 10 pm last night and went down to 90 degrees when I woke up at 6am to water a few plants that really needed a drink. :(
Crossing my fingers for you not to loose any plants in this record heat.
So sorry you lost plants. I noticed yesterday that one of my Aloes and Euphorbia got a little burnt, but they should be ok. Thankfully the temperatures have gone down here now, although they’re going back up tomorrow and Sunday but not as high as this hot spell. Thank you for watching and commenting, have a wonderful day from Edith & myself 🌵☀️🌼🌸🌺🏜
Nice video summary, Daz! Hope you and all your plants are ok. Wishing you and Edith a relaxing rest of the day! Stay cool and happy growing!!👍😎🌵🌺🌸☀️
Thank you, Joe 😊 I’m sure the plants will be fine thanks to the shade netting, glad I decided to get it just a day before the heat arrived! Thank you for watching and commenting, have a wonderful evening from Edith & myself 🌵🌼☀️🌺🌸🏜
Your Cactus are so lucky to have you!
Thank you 😊 Thanks for watching and commenting 🌵☀️🌼🌺🏜
Great and dramatic video, well chosen music intensifying the suspense
Thank you so much, Magda 😊 Hope you and your plants coped well with the heat. Thanks for watching and commenting as always, have a wonderful day from Edith & myself 🌵☀️🌼🌺🌸🏜
You did well to keep the temperature down in there, my glass thermometer wouldn't go any higher so I took it down to the woods with us. We got an entire campsite with grass like that now 😄 Good summary, hope you and Edith are cooler now 🙂
Thank you, Ziggy 😊 Yeah I’m glad I got the shade netting, and just a day before the hot weather arrived! Haha yeah everyone’s lawns around here are brown at the moment. Thank you for watching and commenting, Ziggy. Have a wonderful day from Edith & myself 🌵☀️🌼🌸🌺🏜
You know it's hot when your camera's tripod takes a dive due to the heat!
Haha yep. There's a foam piece around the part that holds the camera and all the glue behind it melted! Thanks for watching and commenting 🌵☀🌼🌺🏜
We are experiencing the same heatwave as you unfortunately. Highs of 100 Fahrenheit for weeks on end. Miserable! Tennessee USA
I couldn’t deal with these temperatures for that long. I don’t mind during the day so much, but it’s the hot nighttime temperatures here at the moment that’s unbearable. Having no aircon here makes it worse. Thanks for watching and commenting 🌵☀️🌼🌸🌺🏜
It’s been way too hot here in Croydon. We had fires break out yesterday and last night my indoor temperature read 29.1c at 11.30pm 🥵🥵🥵 it is cooler today but our homes are built to keep the heat in. So it will take a few days for our homes to cool down. It’s currently 4.06pm & my indoor temp is reading 26.4. My fans are on the go in every room and I have 2 on the go in the front room where the temperature monitor is. Hopefully it will be much cooler tonight so people can get a decent sleep 😴 hot, muggy, sticky weather and lack of sleep makes everyone a little more crankier 😂 it’s always easier to warm up then it is to cool down I think.
Totally agree, Laura. Last night was absolutely unbearable, I didn’t sleep well at all. Feels more humid today and I think it’s going to be another uncomfortable night 🥵 Thank you for watching and commenting, Laura. Have a wonderful, and cool evening if you can, from Edith & myself 🌵☀️🌼🌸🌺🏜
I have the same thermometer and it reached 47 degrees on Tuesday afternoon I have a 40-% shade cloth I have only had the greenhouse up since spring it’s 6x6 polycarbonate I had the window open and I open the door fully over the past month the temperature is regularly in the 30s so I’m researching a solar powered fan by the way I’m up north in Wigan so I think maybe your thermometer has been cooked because I also have a thermometer with built in humidity meter what I kept in my snake vivarium it was reading 45 degrees but that was under a shelf 🥵
I think it would have had a higher reading without the 90% shade netting over the greenhouse, but I've been seeing other peoples greenhouse readings from both days in different parts of the country, apparently some peoples thermometers read temps in the mid 50s! I think some of them were left in the sun lol. Thanks for watching and commenting 🌵☀🌼🌺🏜
Here in the Philippines specially Region 1 where I'm from, we reached 50°C and we have 90% humidity. In 1 hour some of my cacti got sunburnt! 🥵
Yes Edith has told me it can get very hot there 🥵 I will have to experience it one day! Thank you for watching and commenting 🌵☀🌼🌺🏜
@@Cactimania yes! You and ate edith should visit the Philippines soon! Our beaches are breathtaking! ( Don't forget to wear sunscreen tho 😆😆)
Yeah my dragonfruit is leaning.
I take it it’s a large dragon fruit? Thanks for watching and commenting 🌵☀️🌼🌺🏜
@@Cactimania unfortunately not. I'll have to be patient. I do know I'll have to tie it up eventually. But they were fine a few days ago but suns hitting em hard. Got the seeds from one i ate. All of your cacti and succulents and literally perfect. I use to work at a conservatory and they all remind me of our desert room. Thanks for your tips and suggestions.
@@chrisgoldbach4450 Thank you 😊 I have some two year old dragon fruit plants and I do water those more frequently, maybe yours will perk up with a little drink? 🌵☀️🌼🌺🏜
@@Cactimania I shall check. Hit em all not too long ago but with the sun your most likely right. Whats your favorite cactinornsucculent out of all that you grow?
@@chrisgoldbach4450 Astrophytum asterias is my all time favourite cactus, probably always will be. Other favourites include Gymnocalycium, Neoporteria, Copiapoa, Ferocactus and also Euphorbia 🌵☀️🌼🌺🏜
Killer heat I live in a caravan it reach neally 40degres.unbarable tbh..
I have a green house out side lot of my plants got burnt n wilted
Not good ☹️ Last night the temperatures were ridiculously high, didn’t sleep well. Thank you for watching and commenting 🌵☀️🌼🌺🏜
