A couple weeks ago, we used "bayonet" tines for the first time on the greens. The slices left were barely noticeable after rolling and mowing. A few days later, the marks were invisible but testing with a soil probe reveals excellent rooting in the channels opened up by the tines. In each of the slices, new roots have developed, sometimes down the entire length of the tine. Without venting, it is unlikely we would be growing new roots in August - especially this August. The channels formed by the bayonet tines offer some much needed oxygen to the rootzone allowing golf courses to keep their greens healthy in tough conditions.
