Here is my solution to rooting outdoors and keeping the cuttings safe from fungus gnats. When it starts to leaf out you just tie the bag around the wood under the foliage.

Great idea! What size bag is that? Where, and how much?

The bag is 10" wide and 17" tall. I found it on ebay and there are tons of them.
The start is in a 32oz deli container drilled full of holes.

I usually do not have a problem with fungus gnats outside;
they (if any) tend to get blown away by the wind...

They are more of a big pain in the GH and inside the home.

I've lost cuttings outside from them.
