September Garden Guide

*  Allowing September rose blooms to stay on plants aids in winter protection. 
    Watch for black spot on roses and remove infected leaves
*  Lift gladiolus corms when leaves begin to brown.  Dry in sun a few days.
*  Divide most perennials except asters and mums, which haven’t bloomed.
*  Divide and replant peony roots.  Avoid planting too deeply.
*  Bring coleus, geranium, caldium and begonias indoors.
*  Place amaryllis in cool basement for a 3-month rest.
*  To set buds, Christmas cacti require a rest period and cool nights (55 degrees).
*  Sow snap dragons, cornflowers and other hardy annuals a few weeks before the first frost date.
    Mark where planted to avoid damaging seedlings in spring.
*  Carefully inspect spring flowering bulbs before planting. Discard soft bulbs.
*  Remove newly set tomatoes, blossoms and new growth five weeks before expected frost
    because they won’t have time to mature.
*  Sow annual ryegrass or oats for winter cover and green manure in beds that won’t be
    planted until late in spring.  Keep watered.
*  Remove all weeds from garden before they go to seed.
*  Pinch out the growing points at the top of Brussel sprout stems so bottom sprouts will reach maturity.
*  Watch for early frosts,  Cover the garden when frost is predicted to obtain another month
    of growth.  Water plants well for greater frost protection and maximum growth.
*  Cut back perennials after frost
*  Dig and pot parsley, chives, and tender herbs for transfer indoors to sunny window
*  For better keeping, harvest carrots, beets, and turnips before first frost kills foliage.
*  Gather squash, pumpkins, and gourds when ripe and before frost damage. 
    Leave 2-inch stem on vegetable for better storage
*  Clear garden beds immediately after harvest.  Destroy any diseased plants by burning,
    composting in a hot pile or sealing in container for disposal.
*  Early September is the latest time to plant spring-flowering shrubs.
*  Aerate lawn when temperature is 60-70 degrees
*  Stop planting evergreens by mid-September.
*  Harvest pears when light green.  Separate from branch with slight twisting motion.
*  Harvest grapes & ferilize with 1-cup bone meal per/plant.
*  Harvest apples.  Rake leaves and fallen fruit from apple trees to control disease and inspect
    problems next year.  Be careful not to injure long-lived fruiting spurs when harvesting.
*  Cut out spent raspberry-blackberry canes after fruiting.
