I've started some cucumber seedlings indoors, and I'm really eager to get them into the garden. However, I'm noticing that nighttime temperatures are still hitting the mid-40s here in Southern California. Should I hold off on planting them for a few more weeks, or is it safe to move them outside now?

You're not alone! I’m also planting mine at this time in SoCal. The temperatures can vary quite a bit, but it seems manageable. Plus, having my seedlings has me super excited, even if my partner teases me about my gardening obsession!
It's a little early, to be honest. The general rule is to wait until night temps are around 50°F before planting them outside. I’m in zone 10b and won’t put mine outside until likely April. Just keep a close check on the temperatures, as anything in the 40s can potentially stunt their growth.
Very true! I'm in the same zone 10b, but my lows are about 50°F now, so it's really about watching local weather. Also, checking the soil temperature is a good idea.
I think you'll be fine to plant them out soon! Another week max and I’m putting my transplants in too. Just make sure to keep an eye on the weather!

Haha, I feel you! My spouse thinks I’m a total nerd for getting excited about plants.
