Seasonal Garden Tips
Prepare your beds for fall planting, working organic matter into the soil.
Divide and transplant early-blooming perennials.
Finish cleaning up the garden. Add winter mulch after the ground has frozen.
Plan to mulch with evergreen branches at end of the month. Leave brown foliage of ornamental grasses for winter interest.
Check your winter mulch, adding additional amounts if necessary. Old Christmas tree branches help to prevent loose mulches from being scattered by the wind.
Look for early-blooming bulbs like Galanthus (Snowdrops) and Eranthus (Winter Aconite), and early plants like Hellborus (Christmas Rose).
Cut ornamental grasses to the ground at the end of the month.
Remove all winter debris and remaining mulches. Watch for early signs of disease or insect problems. Begin staking plants that will need support.
Sow seeds if perennials outdoors, making sure the seedbed contains adequate organic matter. Perennial and biennial seeds can be planted through September.
Pinch chrysanthemums and similar plants to encourage side branch development. Watch for slugs. Deadhead and remove yellowed foliage from bulbs.
Watering and weeding are major concerns; mulch will facilitate both. Soak the garden, remove the weeds, and then mulch to retain moisture and reduce weed-seed germination. Dig and divide bearded Irises.
Cut back perennials that have finished blooming, but leave some foliage.
