We'll see how the deciduous trees fared in a month or so. My thought are that the paw-paw and paperbark maples will all be fine. I'm more worried about the willow-leaf oak and Magnolia! Sabal minor seems to get tougher and tougher. They must have seen -17C this winter (dry mind you) but they don't h...

Winter Damage 2014
Hi all. Cold winter this year, lots of damage to many plants. I'd rate this more of a zone 3b/4a winter. Low was -32C, was below -30C twice, many days with highs below -20C, only a couple of breaks. I think maybe Jesse and I change climates for a year! A really tough year. Ilex aquipernyi, I'd rate ...

When you're above 0 (freezing) give it a treatment with a fungicide just in case it is alive. -16F is probably going to be lethal (depending on duration establishment, etc), -16C is survivable but almost certainly would cause a lot of damage. If it saw anything like -16F in or near the meristem ther...

Hey all, I'm thinking about how I will find space to test a bunch of dry-climate plants in my cold, wet, USDA zone 4b/5a climate... I have a bunch of Opuntia hybrids and selections to trial (p.s. if you have extra seeds of any cacti or Yucca please let me know!), both my own and from Tim, as well as...

Make sure that once you see the gametophytpes (the green blobs, look sort of like tiny liverworts) that you mist them with sterile water (boil water, let it cool and then mist them) to allow the actual sexual reproduction to occur (the spermatazoids need water to be able to move). This will lead to ...

I can come close, Kingston hit -29C last night. That means that my garden must have hit at or below -30C, which will be the coldest in 12 years. Yikes. That's -22F, a zone 4b temperature. And here I was getting ready to finally admit to zone 5a status:( Toronto hit a hot and humid -20C last night. I...

These plants don't really have a true dormancy period like many cold climate plants (Yucca 'may' but palms certainly do not)... Maybe the light coloured leaves are due to the plants trying to grow with low light levels (as Cameron suggests) combined with the colder then usual weather and COLD (froze...

The zone rating (USDA, I don't use the Canadian map, it just causes people to underestimate how cold they get) is based on the average extreme minimum temperature that you are likely to experience each year. So, for markham the average winter will hit -26C or whatever. However, it's possible that yo...

Aaron, don't feel too badly. Sclerocactus turn to mush here during their first winter! If that doesn't kill them the next summer will, they can handle so much heat but, like Pediocactus, if you get hot, humid, days and nights (esp. nights above 20C), they'll boil and suffocate themselves to death.

I'd say the Opuntia is one of the Opuntia phaeacantha types, following Andersen (He lumps many of the 'species' like O. chisoensis and similar under phaeacantha), and, ya I agree that is NOT A. parryi. Probably A. americana. That Opuntia 'may' be hardy, depending on it's origin within the species ra...

Kingston: It's been COLD since the ice storm hit about 4 days ago. We've been below -20C probably 5 times already. However, we do have a solid snow base under the ice layer (which is thick enough to easily support human weight), and there's more snow arriving today. More low temps on the way too aft...
