The Weather

Welcome to my first Blog and lets talk about overwintering your plants

Hi Guys 😀 

Welcome to my first Blog on this website 😀 

Winter is very nearly upon us and we have already had a few chilly nights here in Belfast in N.Ireland, Luckily I have just finished bringing in the last of the Cacti and Succulents that are not cold hardy from the Polytunnel into the house to overwinter them.

If you are like me and live in the Northern hemisphere and you grow cacti and succulents either outdoors or in a  greenhouse or polytunnel then you will need to protect any of your plants that can not tolerate the cold temperatures we get here on this side of the planet.

During the Autumn and Winter months I heat my polytunnel at a minimum Winter temperature of 5 Celsius / 31 Fahrenheit and I have a thermostat control that switches on if the temperature drops below 5 c / 41f inside the polytunnel, this allows us to keep a large proportion of our cacti and succulents safe over the Winter to overwinter them during their Winter rest period, but also still warm enough for the Winter growing Cacti and Succulents such as the South African Succulents and the Schlumbergera cacti commonly known as the Thanksgiving and Christmas Cacti that still continue to grow and flower during the Winter.

The Cacti and Succulent Plants that are all going to be left overwintering in the Polytunnel, these plants will be kept at a minimum temperature of 5 Celsius / 41 Fahrenheit, I have a thermostatic heater that switches on if the temperature in the polytunnel drops below that.

Some Cacti still continue to grow and flower during the Winter for example Schlumbergera commonly known as ‘The Christmas Cactus’ and the Thanksgiving cactus’


There are so many different cacti and succulents and they all vary so much in their minimum Winter temperatures and also the minimum temperatures vary so much depending on where they are growing, for example cacti that are being overwintered cool and dry in a dry arid climate with low humidity can survive much lower temperatures, and some of the desert cacti like Opuntia and Rebutia can even survive temperatures that are below freezing compared to the same types of cacti that are being overwintered cool and dry but are in a humidity high country such as where I live here in Ireland and UK.


Most of the Cacti and Succulents like to be overwintered cool and dry and bright ideally at a temperature between 5 – 10 Celsius /  41 -50 Fahrenheit, this encourages them to stop growing and they get to rest over the winter and also encourages blooming in the Spring and Summer of the following year.

If you want to learn more about Overwintering Cacti and Succulents then you can read the Article I have wrote for the growing tips on this website HERE

I have made a couple of videos on my You Tube Channel Desert Plants of Avalon on How to Overwinter your cacti and Succulents and also How to Overwinter your Cacti and Succulent seedlings during their first year and both of these videos are below : 


I filmed a series of fun video vlogs for my You Tube channel Desert Plants of Avalon when I was bringing in the Cacti and Succulents to overwinter from the polytunnel into the house, and in these video vlogs I share lots of information about each cactus and succulent and about their individual minimum winter temperatures, check the video below if you want to see the first part of my Overwintering video Vlog

I hope you enjoyed my first Blog on this website and stay tuned for many more to come 😀

Sending you all lots of LOVE and PLANT POWER from across the Emerald Isle 😀
