1. Individual 4" pots would be best. Don't put more than one cutting per container. If one starts to rot it may cause the others to rot as well.

2. Only water when the top of the medium feels dry. You can stick your finger into the edge of the pot and only water if it is dry. Let them dry out and they won't root, keep them too wet and they will rot. Use a sterile seed starter mixture (peat moss/vermiculite), or perlite, course sand, vermiculite, or a mixture of those. They retain moisture while allowing for adequate drainage as well. The medium should be moist, not soggy.

3. I would leave the vents open slightly to allow a little air exchange in little "mini greenhouse". Don't open them all the way because you don't want too much moist air to escape. You want to see little water droplets on the sides of the plastic from condensation inside the greenhouse.

4. You want to keep them out of direct sunlight. A shady spot in the yard is fine. Direct sunlight will cook the cuttings.

5. You want the cuttings to be semi-hardwood, so somewhat green.. not completely brown. Brown indicates hardwood cuttings and they can be more difficult to root. You can cut the leaves near the stem but don't damage the leaf node. That is where new growth will come out. It doesn't really matter if there is a small portion still remaining. It will dry up and fall off. Or you can just simply pluck the leaves off. No biggie. Only leave a few leaves on the top most portion of the cutting. You don't want to leave too many leaves because the cutting will lose too much moisture and dry out, but it needs at least two for photosynthesis.

Good luck and happy propagating! =]

I have the boxwoods in their pots as of this morning, following the above. I suppose the only concern at this point is the outside temperature. I have it in the shade, but it's going to be in the 90's for the next three days, and in the high 80's for infinity as far as the Weather Channel says. Would I be better off just taking them inside for the next week if that were the case?

Humidity is pretty high outside, which I imagine is a good thing. The dome also has a little sweat on it so I believe we're okay on that side.
