I have a few that are 10+ years old and I have never seen so many durn acorns in my life . Pros , hold deer early cons , they are all gone by late oct . Im about to start planting some more . The plan is to plant a white oak for every sawtooth I plant. That way I get the best of both worlds acorns in 6 or 7 years, and white oak acorns in 20 to 25 years. If the sawtooths die off I will be left with a good timber quality tree plus one that will drop acorns for my grand children's children .plan on putting trees on terris in open field about fifty ft apart . I got miles of terris to work with so I'm not wanting to crowd them at all. Drout may be an issue on the terris ,the ones that are doing well are in low bottom land water is not a problem there. I'm also going to use tree tubes on all of them . Cost more but u can keep up with where u put them exactly that way. Plus the sawtooths want to bush out real bad the tubes make them grow up instead of out.
