In NJ and much of the rest of the country this week has been a cold snap. After above average temps, we dropped 15F below average. Yesterday I talked to some people who do deep tine aeration (and other services) wh said on Monday they had a hard time getting penetration in near frozen Long Island, NY ground. Just got home, and took soil temps (33F, ambient 29F) and and used a probe to take some soild samples (a few were easy, a few impossible). Saturday is supposed to be low 40s after another cold day tomorrow with temps tonight around 20F. Has the window passed? Or would the warm day Saturday be enough to make it work? Saturday night is expected to be in the upper 30s, Sunday in the mid to upper 40s but raining. However, my understanding is that plugging is possible in the rain. The tines, arriving tomorrow, are .6" OD, .47"ID, side eject. On the 3/8" mount tine, the core deflector is built into the tine, and the side eject is exposed while the tip is in the ground. Although these are mini "quad' tines, they are about the size and stiffness of regular tines and the Deere Aercore 800 uses the mini tines in one row, 4 banks of 6, rather than the 6 banks of 8 on many other aerators. So, too late? Should the dormant seeding be rushed to Saturday instead? It had originally been planned for next week if possible. However, if the ground is frozen the Ryan verticutter probably won't work. Next week (forecasts available until Thursday) appears to be just above freezing during the day and below at night.
