Ok, so that might not be the clearest answer to this question. But the truth is, it actually really depends. So I'm going to keep this short and sweet and give you a few tips to this highly popular question. To mist or not to mist.
The best thing to remember is if your plant comes from a humid place, ex: rainforests, areas that have high humidity, then your plant will likely love the humidity from misting. Always check out where the plant originates from and if it's a humidity lover. Remember, just because a place is hot doesn't mean it's humid so be careful to clarify the difference. Ex: Cacti + desert- likes low humidity
A few plants that love humidity are:
Just to name a few.
-Best time to mist is in the morning. Your plants will enjoy the humidity all day and can slowly dry out with the daylight.
-I've found that using rainwater for misting when I can is great. It's a perfect way to create a feel of their natural environment. However, filtered water is good too. Bottom line, the less chemicals the better.
-Try to mist your plants when they are grouped together. Again, creating a feel of a natural habitat and thriving together.
-You don't need to water and mist your plants at the same time. That will likely overdo it. You want to be careful not to create a space for root rot to develop or for disease or pests to grow. If you start to notice any of these, cut back on misting.
Misting your plants can be a great benefit under the right conditions. So give it a try with plants that are used to that type of environment and use your best judgement with how well/ or not it's working. Once you find that perfect balance, you and your plants will see the benefits of misting.
