Month of September Garden Tasks
September marks the shift toward fall — cooler nights ease heat stress on plants, and it's the ideal window to plant, divide, and prepare for the seasons ahead.
Plant spring-flowering bulbs like tulips and daffodils once soil temperatures start to cool.
Divide and transplant overcrowded perennials while the weather is mild and roots have time to establish before winter.
Continue harvesting the last of the summer vegetables before the first frost arrives.
Overseed or repair thin patches in the lawn while soil is still warm enough for good germination.
Reduce fertilizing on trees and shrubs to help them transition into dormancy.
Fall is actually one of the best times to plant trees and shrubs — cooler air and still-warm soil let roots establish well before winter, with far less transplant stress than spring planting.
