Things to do in September

  • Harvest potatoes when the tops die down. Store them in a dark location.

  • Apply parasitic nematodes to moist soil beneath rhododendrons and azaleas that show root weevil damage (notched leaves).

  • Optimal time for establishing a new lawn is August through mid-September.

Question of the Week

I have a small garden plot that I have let go fallow over the summer, but would like to plant something to keep the weeds down until next year. Most of the cover crops I read about look a lot like the invasive weeds I'm always pulling! What should I plant that can be easily tilled into the soil for planting next spring?
