PlantCatalyst® October Checklist

October brings cooler breezes and falling temperatures, at least in hardiness zones 3 to 5. While gardens in the winter months usually see little to no activity, there are a few things you can do to wrap up before the first snowfall hits. As we count down the days, here’s a quick checklist to keep you on track:

PlantCatalyst® October Checklist

Vegetable Garden

  • Finish harvesting beans and peas. Cut away the plant while leaving the roots in the soil to fix nitrogen released into the soil.
  • Harvest squash and pumpkins before the first frost.
  • Move tomatoes and peppers indoors to allow final ripening.
  • Cover asparagus and rhubarb beds with a mulch, manure, or compost.
  • Now is the time to plant autumn garlic bulbs and onion sets.
  • Dig and store potatoes in dark, moderate humidity environments.
  • Harvest any last root crops, or mulch heavily.
  • As always, continue to pull weeds from the soil.
  • Start working manure or composted material into the soil so it’s ready by the next growing season.

Greenhouse Maintenance

  • Begin moving disease-free plants inside.
  • Remove all covers to allow as much light as possible to pass through.
  • Make sure your greenhouse heater is working properly in case of any early frosts.
  • Remove any fallen or dead plant material to keep the environment disease and pest free.
  • Cold frames should be built and ready for use. They’re a great way to prolong the growing season.
  • Configure greenhouse watering systems to use 2 ounces of PlantCatalyst® solution for every 50 gallons of water for best results.

Yard Maintenance

  • Be active in raking fallen leaves off your lawn. They can kill grass if not managed properly. They’re also great for composting.
  • Aerate your lawn by poking small holes in the dirt.
  • One final cut should be made before the month is over. Your lawn can be left alone for the winter afterwards.

Flower Garden

  • Collect and store flower bulbs and geraniums.
  • Prune roses to 10-12 inches. Cover with leaves or straw to insulate from winter temperatures.
  • Plant daffodil bulbs, tulip bulbs and allium bulbs for springtime blooming.


  • Harvest any apples before the end of the month.
  • Clear ponds of any debris. Consider putting a net over the top to prevent material from falling in.
  • Harvest sunflower heads – can be used as birdseed!
  • Clean, sharpen, and oil tools before storing them for the winter.
  • Give conifer hedges a last trim for the winter sets in.
