I'd recommend
metal fencing for the apple tree, lilac, and the Norway spruce. You can get a roll at home depot or probably other similar stores. Go with a 3 or 4 foot height. I'll attach a picture of this in the next post. The metal cage will allow the plants to develop big and wide branching structures, which is important for these 3 species.
For the oak and maple you could use either the
metal fencing or tree tubes. See the recent MWL blog about
protecting newly planted trees. Using tree tubes will result in plants that do not have branches below the top of the tree tube, which is just fine for oaks and maples.
Please feel free to post pictures of your plants (with or without protection)! And feel free to follow-up with any questions.
