Hello Everyone,

I live in zone 7A and have a number of junipers outside on a north south axis on the south side of my house. The temperatures have been mild yet windy. We usually have a fair degree of humidity however I am concerned that the wind will dry the junipers out. So far I can't get any consensus on whether I should give the junipers a humidity tray or mist them to help them with transpiration. Is this a good idea? Any thoughts would be greatly appreciated!

Humidity tray is a sure no outside. If you get lots of rain when you are not there to empty it the tree will drown.

I live in climate similar to zone 7 and have never misted any tree except for rare occations with neem oil treatment.

Humidity trays and misting are myths, they both don’t do absolutely nothing. Humidity doesn’t magically stay around the tree, or increases only around the tree.

In general, you’re right. But in the case of junipers, you’re also wrong
About misting, that is.

They tend to grow in arid areas, and adapted to suck in morning mist from the air, as that’s often all they get for rather long times.
So they do like getting misted early in the morning, before it gets hot (at which point their foliage closes the pores and you can just spare yourself the burden, as they won’t be able to take it anyways).


They can do without too, obviously, since they’re being watered whenever they need, so it’s not like it makes that much of a difference: I spray their foliage with the hose as a habit just because, but it’s not like one has to.

BUT the fact they do is helpful with fertilizing, as they happily suck up foliage feeding as well. So about every 2-4 weeks I do mist them with water and a few drops of superthrive.

From what I can tell, they do like it

humidity trays do not help.

On the other hands, juniper can take up a lot of moisture through the foliage. So I show mine frequently.
