September Garden Calendar
Get Ready
- Make sure you've ordered daffodils and other spring
bulbs for October planting.
- Build or buy compost bin in anticipation of autumn leaves.
Plant
- Plant cool season leafy root vegetables: Carrots, Beets,
Turnips, Lettuce, and Spinach.
- Sow hardy annuals: Sweet Alyssum, Calendula, Annual
Pinks, Snapdragon, and Sweet Peas.
- Sow rye grass seed in winter lawns.
Fertilize
- Stop feeding mums when the buds start showing color.
- Acidify Azaleas and Camelias.
Water
- Slow down watering of Azaleas and Hydrangea to allow
them to harden against winter freezes.
- Spray foliage of Camelias in anticipation of their bloom.
- Water potted plants and hanging baskets frequently.
Prune
- Disbud Camellias, Dahlias, and Chrysanthemums to produce
specimen blooms. It is generally not a good idea to prune this late
in the year, because new growth will be more susceptible to winter
freezes.
Miscellaneous
- Turn compost pile.
- Propagate by layering. Scrape underside of a strong
branch, bend down to ground, cover with soil and weigh down with a
brick. Water from time to time and end of branch will put out new growth;
becoming a new plant.
- Pick flowers in bloom and dry for future arrangements.
Bundle flowers together and hand upside down in a dry, sheltered area.
- Repot houseplants. Prune away damaged foliage and give
a good dose of food.
