August

Prepare
Plan beds for bulbs. Order Tulips, Hyacinths, Dutch Iris, Daffodils, Narcissus, and Amaryllis. Prepare beds for October planting by adding compost or leaf mold.

Plant
Daylilies in a sunny location, they will be well established before winter.
Divide and transplant Louisiana Iris, Easter Lily, Canna, Liriope, Ajuga, and Shasta Daisy. Plant cool season vegetables: Broccoli, Cauliflower, Brussels Sprouts, Cabbage, Spinach, Potatoes, Lettuce, Carrots, Beets, Radishes, and English Peas. Plant warm season grasses: Buffalo, Bermuda, and St. Augustine. Mums should be planted for September bloom and fall color.
Marigolds, Asters, Zinnias, and Celosia can be planted to replace faded annuals. Plant seeds of Calendula, Columbine, English Daisy, Forget-me-not, Pansy, Sweet William, and Violet.

Fertilize
If acid loving plants including Azaleas, Camelias, and Gardinia show signs of chlorosis (yellowing of leaves), a treatment of Iron Chelate should cause leaves to regain their green color. Feed mums with a complete fertilizer every two weeks and water thoroughly until buds show color.

Prune
Cut back annuals such as Impatiens and Vinca to encourage fall blooms.
Disbud Camellias, Dahlias, and Chrysanthemums to produce specimen blooms. Continue to remove dead heads in the garden to stimulate blooming.
Cut back rose canes to 24-30 inches from ground for autumn blooms.
Remove dead and damaged wood from trees and shrubs.

Water
Water garden deeply, but infrequently throughout the month.
Water early in the morning or in late afternoon. Water on leaves during the hot of the day can cause the sun to burn leaves. Potted plants and hanging baskets need to be watered daily. Make sure Azaleas and Camelias stay well watered, because they are forming flower buds for next year.

Miscellaneous
Mow weekly and leave clippings on the lawn.
Turn compost pile. Feed the birds.

Planting
Plant Pumpkin seeds for a Halloween harvest.
Use Portulaca or Marigolds to fill in bare spots of flower bed.
Root cuttings of Azalea, Boxwood, Camellia, Gardenia, Holly, and Poinsettia in coarse sand. Cuttings should be 4-6 inches from new growth with lower leaves removed. Plant now for color in the fall: Marigold, Zinnia, Celosia, and Joseph's Coat. Daylilies may still be planted. Start cuttings for house plants: Ivy, Wandering Jew, Philodendron, and Begonia. Plant fall vegetables: Cabbage, Parsley, and Collards.

Fertilizing
Do not fertilize Camellias after July 1. Fertilize Chrysanthemums around July 15. Fertilize all of the garden as you did in March. Fertilize lawns with well balanced fertilizer.

Pruning

Remove faded flowers from Crape myrtle to encourage a second blooming.
Pinch back Mums before July 15.Cut back broken or withered fern fronds. New growth will appear for fall garden.
All Vegetables must be picked regularly to ensure continued bearing.
When cutting Boxwood into a hedge, make sure the base is wider than the top to allow sunlight to reach base of plants.
Remove dead limbs from trees and shrubs.
Roses should be pruned to encourage fall blooms.
Remove flowers from basil and cut mint to encourage new shoots.

Mulch
Check mulch on Azaleas and Camellias mulch should be at least 2 inches thick.
Zinnias and Mums must be kept mulched to reduce cultivation necessary and conserve moisture.

Miscellaneous
Water Azaleas well because they are setting flower buds now.
Cut grass at 2.5 - 3 inches during hot weather.
Water the whole garden deeply once a week.

 Home Accent
Never leave house plants in a closed home over a vacation. Either water and place under a shady tree or have a friendly neighbor come in and water them for you.
