What to do in the garden in October


Planning
•      Now is a great time to plan a new garden bed.  Use newspaper or cardboard covered by mulch to remove lawn and/or weeds for conversion to garden beds.

Maintenance and Clean Up
•      Recycle plant material and kitchen scraps into compost.  Adding plants that have gone to seed or are diseased could spread problems unless you are using the "hot compost" method (120-150 degrees).

•      Drain or blow out your irrigation system and insulate valve mechanisms, in preparation for winter.


•      Use newspaper or cardboard covered by mulch to discourage and/or kill weeds.


•      Clean and paint greenhouses and cold frames for plant storage and winter growth.


•      Harvest sunflower heads; use seed for birdseed or roast for personal use.

•      Dig and store potatoes; keep in darkness, moderate humidity, temperature about 40°F.  Using your own potatoes as seed potatoes for next year could continue a disease problem if you had one this year.  See this link
•      Harvest and immediately dry filberts and walnuts; dry at 95 degrees to 100 degrees Fahrenheit.

 See this link for filberts 
•      Ripen green tomatoes indoors. Check often and discard rotting fruit.


•      Harvest and store apples; keep at about 40°F, moderate humidity.


•      Harvest squash and pumpkins; keep in dry area at 55 to 60 degrees F.


•      Place mulch over roots of marginally hardy plants for winter protection. Roses, azaleas, rhododendrons, berries, and many other plants also benefit from mulching.


•      To suppress future pest problems, clean up annual flower beds by removing diseased plant materials, overwintering areas for insect pests; mulch with manure or garden compost to feed the soil and suppress weeds.
Cover cropping is another good option with similar benefits.

•      Cover asparagus and rhubarb beds with a mulch of manure or compost.


•      Clean, sharpen, and oil tools and equipment before storing for winter.


•      Store garden supplies and fertilizers in a safe, dry place out of reach of children.


•      Prune out dead fruiting canes in raspberries.


•      Now is a good time to add organic material soil
•      Lime if indicated by soil test results.


Planting/Propagation
•      Dig and divide rhubarb. (Should be done about every 4 years.)


•      Plant garlic for harvesting next summer.


•      Propagate chrysanthemums, fuchsias, and geraniums by stem cuttings.


•      Save seeds from the vegetable and flower garden. Dry, date, label, and store in a cool and dry location.


•      Plant ground covers and shrubs.


•      Dig and store geraniums, tuberous begonias, dahlias, and gladiolas.


•      Pot and store tulips and daffodils to force into early bloom, indoors, in December and January.



•      Pest Monitoring and Management
•      Gather and use windfall apples in cooked dishes.  Hot compost any that are not useful for eating to reduce the risk of harboring apple maggot or codling moth larvae.


•      If Box Elder Bugs are a problem, use a broom or whisk to sweep them into a bucket while temperatures are cool.  For larger numbers, a vacuum may be more effective.  Dispose of vacuum bag shortly after vacuuming up large numbers of insects.  
•      Rake and destroy diseased leaves (apple, cherry, rose, etc.), or hot compost diseased leaves to help reduce spread.


•      Spray apple and stone fruit trees at leaf fall to prevent various fungal and bacterial diseases. For more information, see Managing Diseases and Insects in Home Orchards (PDF - EC 631).


•      If moles and gophers are a problem, gathering soil from the mounds to expose the holes can discourage them.  Trapping is the official recommendation, but it is often ineffective and not necessarily humane.


•      Control fall-germinating lawn weeds while they are small. Hand weeding and weeding tools are particularly effective at this stage.


•      Monitor landscape plants for problems. Don't treat unless a problem is identified.
