To Do in October

Well, wasn’t September fun?! Dry, wet, dry, OMG wet. Heartfelt sympathies to those who suffered loss by Florence. For those of us whose gardens were only moderately affected (or not at all) here is the October calendar.

Fertilizing
Not much to do here unless you are planting spring flowering bulbs. Should that be the case, incorporate a little balanced fertilizer (10-10-10 or equivalent) into the soil as you plant. Store any leftover fertilizer in a dry place for the winter.

Planting

  • The above-mentioned spring flowering bulbs (e.g. hyacinths, tulips, daffodils, crocuses, etc.).
  • Pansies! Those plucky members of the Viola genus who can brighten up a gray winter day should be on everyone’s list unless, of course, there are deer nearby.  Apparently, the pansies make a great dessert after a meal of azalea branches.  Plant them soon as the more established they are when it gets cold the better able they will be to withstand the cold.
  • “Fall is for planting.” It’s not just a slogan from the nursery industry. It is gospel. The very best time to plant any new landscape plants you have been planning is now.
  • Peonies can be planted or transplanted now.
  • In the vegetable garden consider a nitrogen fixing cover crop like red clover, hairy vetch or winter rye. This will help keep down the weeds and add nitrogen to the soil. In the spring just till it into the soil to add nutrients and organic matter.
  • If you happen to be one of the foresighted people who have a cold frame now is the appropriate time to plant a winter’s worth of salad. Lettuce, green onions, radishes, carrots, spinach and other leafy greens will grace your salad bowl all winter if planted now.

Pruning
Once frost (It’s October. It is going to frost!) has finished the decimation of the perennial garden cut off all the dead tops and throw them on the compost pile. Root prune any trees or plants you plan to move in the spring.

Spraying
Unless you have a lace bug problem, it is time to clean up and winterize the sprayer and store the pesticides in a secured, dry location that will not freeze. As for the lace bugs, they are active whenever the leaf surface temperature is warm enough (i.e. whenever the sun shines on the leaves). A horticultural oil spray can be helpful in controlling both feeding adults and egg stages.

Lawn Care
Maintain adequate moisture levels for any newly seeded or sodded lawns.  Avoid leaf buildup on lawns.

Tall fescue and bluegrass (not the fiddlin’ kind) can still be planted in October.

Propagation
Keep an eye on any new cuttings in the cold frame (the one without the salad greens in it). They should be checked at least twice a month and watered as needed.
If you are a gardener lucky enough to be able to grow rhubarb now is the time to dig and divide it.

Other stuff to do that will keep you outdoors while the leaves turn color:

  • Take soil samples while they are still FREE. NC Department of Agriculture will charge for them from November to April.
  • Put those raked 0r blown leaves into the compost bin or till them into the veggie garden.
  • Clean fill and put out the bird feeders.
  • Dig and store (cool, dark, dry) tender summer flowering bulbs (E.g. gladioli, dahlia, caladium) before frost.
  • Clean up lubricate and otherwise prepare lawn and garden equipment for its long winter’s rest.

A mea culpa. This writer neglected to inform you that it is time to band trees that are susceptible to canker worm invasions. This involves wrapping and securing the trunk with a coarse material like burlap or quilt batting about 4 or 5 feet above the ground. That in turn is wrapped with a corrugated paper wrap that is then covered with the stickiest gooeyest stuff you’ve ever played with. All these materials are available at some nursery/garden centers, one of which is very proximal to the Durham Cooperative Extension office.

For a fun activity now that will yield fresh living flowers in the bleak mid-winter try your hand at forcing spring flowering bulbs. Plant bulbs in pots early in October and place them in the refrigerator. In twelve weeks bring them out into the house and watch them grow and bloom. Kids love it.
