What Temperature Is It Safe To Put Houseplants Outside? There needs to be night temperatures of 50 degrees consistently for a significant period of time. When it holds this range, then you know it’s time to move your plants outdoors again.

If you don’t have a green thumb and struggle with keeping indoor plant alive, welcome to the club. You might get a a week of warmer weather and think you are in the clear, but that’s just not the case. If suddenly temperatures begin the drop again, you must transfer the plants back inside. We all know that spring can be fickle.

It’s important to keep an eye on the weather – specifically the night ranges – and ensure that your green friends are never outdoors in degrees lower than 45 degrees. If you care for tropical plants, anything lower than 40 degrees will cause severe harm.

Things To Consider

  • When first transferring your plants, be sure to move them into a shaded area at first. You don’t want to overexpose them to the sun. They need to readjust to outdoor weather.
  • Too much water can be just as bad as too little. So, if there is a severe rainstorm, you must do your part to pull them from it. It’s not about just leaving them to their own devices.
  • Generally, most houseplants can live outside between the months of May and September. Depending on where you live, you might find that you can stretch this range a bit further. However, this is a good estimate.
  • Another good indication is to wait until 2-4 weeks since the last frost. Then everyone should be ready to move.

The Power Of Rainwater

rainwater and plants

If you are having a drought and your outdoor plant isn’t really getting a lot of natural rainwater, you should consider watering it from the house. However, consider keeping a bucket outside to collect natural rainwater as it falls because it really is the best for plant life due to the traces of nitrates naturally found in it which is essential for plant growth.

This is also great for any indoor plants you might have. So, if you hear of a storm coming up, consider adding a few bowls outside to collect rainwater!
