Plant Parent Basics: Air Flow
A general rule we follow is where there are humidity trays, let there be ventilation. Tropical foliage plants that need humidity trays, like this Calathea species, need ventilation too, especially in winter.
This month, we are featuring a series of articles that will teach you how to navigate the basics of plant parenthood. This week, we’ll be discussing air flow.
Why is air flow important to plants?
Sure, it sounds obvious that plants need air. However, they do nee fresh air just like us for various reasons. Fresh air can do the following for plants:
Lowers temperature in especially hot weather.
Lowers humidity in moist conditions that can encourage pest and disease.
Strengthens the stems and increases disease resistance.
Removes traces of toxins.
Cacti need ventilation during the summer months. This can be provided by a small fan or by placing them outside for the summer.
How do I provide fresh air to my house plants?
Fresh air is provided by ventilation. That can be accomplished by either opening a door or window in the room where the plant is growing. You can also provide a small fan for your plants as well (this can be especially helpful in winter when opening the window is a no go.).
Ventilation is particular important in the summer months for succulents and cacti.
Can fresh air be bad for some plants?
There is a difference between fresh air and draughts. Draughts are air currents moving quickly and directly across plants. The air is usually several degrees colder than the plant. They can cause leaf fall and other symptoms that are damaging to your plants. Keep plants away from doors you open often especially in winter.
The white and gray crust on this pot can be a warning sign the plant is not getting enough ventilation as it dries between waterings.
