Buyer’s Guide To Keeping Your Tropical Plants Humid
Here, we are going to answer questions that a buyer might have when looking for one of these products:
When should I use a humidifier for my plants?
Ideally, you want your plants to be living in an environment as close to their natural one as possible. Under most circumstances, our homes are extremely dry.
If you have tropical plants or those that grow in misty forests, they like humidity. So, if you have orchids or an English Ivy, for example, you’ll need to increase the humidity levels in the room where they’re located.
Where to place my plant humidifier?
Optimally, the plants should be placed as close to the humidifier as possible. If you can’t position the humidifier right next to the plants, use one with a 360-degree nozzle.
That way, you can point the mist directly at a grouping of plants.
