Gardening in August

As the garden season is winding down, following are a few suggestions on “Gardening in August”:

Quit fertilizing rose bushes, shrubs and trees after August 15th.
Start dividing flowers that need it, i.e. irises, hostas, daylilies, grasses, etc.
Continue watering evergreens until a hard freeze.
Continue weeding your garden.
Continue deadheading flowers that will continue to bloom.
Remove deceased plants from your garden.
If the annuals in your planters are wore out, consider replacing them with fall mums.
Harvest your herbs.

 

Important Garden Tasks to do before Winter:

  1. Clean and sharpen garden tools.
  2. Mow around young trees and fruit trees to prevent mice from nesting there.
  3. Put tree guards on or wrap young trees with tree wrap to prevent rodent damage.
  4. Read your animal/insect repellents to verify when to quit using them.
  5. Move indoors in a safe place, protected from young children, any liquid garden products.
  6. Clean, store and turn upside down outdoor containers.
  7. Rake fallen leaves off grass.
  8. Give all trees and shrubs, especially evergreens and boxwoods, a thorough watering before the ground freezes hard.
  9. Remove water from garden hoses before storing away.
  10. Cover compost pile with plastic or straw.
  11. Drain fuel tanks on lawn mowers, leaf blowers, etc

Your Perennial Garden: What plants to cut back or leave until spring.

Before winter, remove all diseased debris and broken branches from your flower garden.  Discard any remaining annuals.

Recommended perennials to cut back in fall are:  bearded iris; monarda (bee balm) unless it is new growth; gaillardia (blanket flower); nepeta (catmint); columbine; daylily (now or spring); bush clematis; helianthus; hollyhock; ligularia (now or spring); penstemon; peony; and helianthus.

These perennials are recommended to leave for spring cutting:  asclepias (butterfly weed); chrysanthemums (mammoth mums); and heuchera (coral bells).

Birds will appreciate it if you leave echinacea (cone flowers) and rudbeckia (black-eye Susans) or any other seed producing plants standing through winter.
