I hear there is a heat wave in BC. How are CP growers protecting thier plants from the heat and drought?

Hi Dennis, I can't read your post yet, but as a general rule, most CP hate it when the temperature gets over 35C. Some can cope with higher temperature, some can take higher temperature for a short period of time. Try using this Heat Index Calculator to calculate the "feel like" temperature. Note that at 35C, 60% Humidity, it feels like 56C! I'd be cooked too.

A/C Some plants just cant be grown properly without some equipment. In my setup, without my A/C, its gonna be byebye helis. Even at only 25C outside. Thats mean 27C in my appartment, 29C in my terras, and 33C with the lights on. So, just imagine 30C outside. Impossible growing helis in these conditions, exept 2-3 species/hybrids. And they will not thrive at all. The leaves will have red/rust spots on them, and other pests problem. They will grow, but at 50%.

I'm fortunate to grow plants that like the heat. The Sarracenia only grow faster with the heat, although the trays need filling every couple days. Anything that doesn't like the heat gets moved into pure shade until the heat passes. Our heat waves only last a day or two so it's not usually a long term problem.

It's been dry and sunny here as well...going up to above 30C today and tomorrow. Growing the Darlingtonia outside this summer...been outside since early May. To protect them from the heat,they're grown in a 16 inch white pot, with other pots around it to keep the sun from shining directly on the pot's sides. And the cobras get some rain barrel water poured from the top at least once a day on the hot days. Seems to be working so far...flower spikes coming up followed by the new pitchers. dvg

I keep mine in my room (I live in basement), it's few degrees cooler than outside, and the temperature change isn't as dramatic

After just going through 5 or 6 consecutive days of +30C or higher, with one day hitting 35 in the shade, my Darlingtonia seem unaffected by the heat.
In fact, they are putting up new pitchers and flowers, new growth that is going up at an accelerated rate from years in the basement under lights.
These plants are out in full sun from 11:00 AM until about 9:30PM at night, and have been outside full time since early May.
I was experimenting with having them outside last fall and they were fine and decided to expand the outdoor growing of them through spring and now into summer.
Now I know these plants are much tougher and tolerant of hot weather, than I first expected.

Here in Victoria the temperature has been in the low 20's for the past week. The temperatures are not to bad it is the lack of moisture. According to the federal weather website Victoria has only received 10.2 mm of rain since the beginning of May. The rain barrel for the cp.'s is getting pretty empty. I feel sorry for Maiden with the 35c, that's hot!!

Have you been doing anything else eg., flushing their pots daily, melting ice cubes on the surface, container with large surface area, etc? Also, what were the average nighttime temps? I've read that if nights are cool then plants can tolerate much hotter days. cpgeek

I do run rain barrel water through the pot at least once a day and even more than that on the ultra hot days....haven't had to resort to ice cubes yet.
My cobras are growing in a 5 gallon (20 quart) white plastic pot that is 16 inches in diameter.
The pot's growing surface tends not to get too much direct sun shining on it because of the number of plant's pitchers shading the surface.
And maybe the saving grace is the cooler nights here...July average for Edmonton is 23 for the high and 13 for the night time low.
We've been a little warmer than that this season, but the nights are almost always below 20C and usually get down to 17C here even on the hottest of days.

Thanks Dvg. Perhaps your cooler nights and the large pot combo is why the plants tolerate the hot days. Please do continue to update us on your outdoor growing experiment throughout the summer.

Dennis,
Helis grow on the top of tepuis, in the clouds. Not in Montreal. If you want to grow them outside of their natural habitat you may need some special equipment.

Dennis that it 100% incorrect. Maiden knows what he's talking about.

...I've never been to South America, in the clouds on top of mountains but I imagine it's pretty damn chilly up there with no A/C unit in sight. All the Wistuba guys are always wearing coats and hats. Then again Snapperhead grows them in his greenhouse but he has climate control. So yes, some equipment may be required to duplicate the given plants required growing conditions.
