I found out how cold is TOO cold for my crops


For the last few years in my zone 5 garden, I've been tracking overnight temperatures and seeing just how much cold my cold-hardy crops can actually take—without any kind of frost protection.

I usually cover my beds in winter so I can harvest them all season, but I do leave one or two beds unprotected as an experiment.

What I've found is that many plants can—surprisingly—take a significant amount of below-freezing temps, and it may change the way you view winter gardening completely.

Also: the more snow you get, the more cold they can take! (Even though it sounds counterintuitive.)

If you've ever wondered whether a vegetable crop can survive in your climate, and at exactly what temperature it dies back, I just compiled this very list!

It's based on my own climate and experiences, and I've also noted specific varieties I've grown that were hardier than expected.

Have you noticed that houseplant pests seem to come out more in winter?

I just brought all my potted citrus outside (since we had a relatively warm sunny day) and sprayed them down with a hose, then treated them for thrips. There may have also been aphids on a few leaves, but I didn't look too closely. All I know is I needed to get them under control, stat!

Houseplant pests usually seem worse in winter because we get fewer hours of daylight, dry indoor conditions tend to stress plants, and cold temperatures outside may encourage bugs to seek shelter in our homes.

It can be pretty frustrating when you're dealing with an infestation because it's inside your home—yuck. So here's what I use to make sure the pests don't take over:

Just these 4 items have helped me control every houseplant pest I've come across. The other thing that helps is to remember not to overwater your plants; they usually need much less water in winter than they do in summer, so always check the soil with your finger first before you water.

Good luck! (And I already see my citrus trees recovering from using the Bio Insecticide this week.)
