Okay, so let’s talk about begonias and their temperature needs. I’ve been messing around with these plants for a while now, and I’ve picked up a few things about what makes them happy.
First off, I noticed that begonias really like it when it’s not too hot and not too cold, just like Goldilocks. When I started, I just put them in my living room, where it was usually around 72 degrees Fahrenheit during the day. They seemed to do okay, but they weren’t exactly thriving.

Then, I read somewhere that they like it a bit cooler at night. So, I started moving them to a cooler spot in my house, around 60 degrees at night. I started doing this in the spring. After a few weeks, I noticed they were starting to look a bit more lively, with more flowers popping up.
- Daytime: I try to keep it between 65-75F (18-24C).
- Nighttime: A bit cooler, 55-60F (13-15C) seems to work wonders.
I also realized that humidity is a big deal for these guys. I live in a pretty dry area, so I started misting them every now and then. I also grouped them together with other plants to create a little humid microclimate. They really seemed to appreciate that.
During the summer, it gets pretty hot where I live, so I had to pay extra attention to them. I made sure they weren’t in direct sunlight, and I even moved them to a shadier spot on my patio. I also watered them a bit more frequently, but I always checked the soil first to make sure I wasn’t overdoing it.
One time, I accidentally left one of my begonias outside during a heatwave. It was over 90 degrees for a few days. When I finally remembered to bring it inside, it was looking pretty sad. The leaves were all wilted, and some of them had turned brown. I thought I had killed it, but I kept watering it and kept it in a cool spot, and after a few weeks, it actually started to recover. It even grew some new leaves!
My Tips:
So, based on my experience, here’s what I’d recommend when it comes to begonias and temperature:
- Keep them in a spot where the temperature is stable.
- Don’t let them get too hot, especially during the summer.
- Give them some humidity if you can.
- Don’t be afraid to experiment a little to find what works best for your begonias.
It’s been a bit of a learning curve, but I’m finally starting to get the hang of it. My begonias are looking healthier and happier than ever before, and I’m excited to see how they do in the future. If you’re growing begonias, just pay attention to them, you know, keep an eye on the temperature, and you’ll be golden.
