I'm planting my first apple trees in a few weeks. NWC selected 24 trees for me to try and I'm excited to see them as they have been highly recommended on this site and others. I'm going to cage them with 5' welded wire and will either use weed mats or gly for weed control, depending on the terrain. I have experience planting with cages and tubes but have not protected trunks inside my cages and would like advise on the most effective methods. Between window screen, harware cloth, short (2') tubes, or some other method; what do you recommend and why? Please post pictures if possible. I'm really looking for "fire and forget" options as I do not get to visit my land often. What about gravel in addition to trunk protection? Thank you!
