Yard care and water savings tips

Tips for getting your garden and yard ready for fall.

Pull emerging weeds in beds when ground is moist and before they develop deep roots.

Mulch garden beds with leaves or compost to reduce winter weeds and feed the soil.

Mulch tree and shrub beds with leaves, wood chips or bark.

Plant trees, shrubs, and many perennials in early fall to give them a good start.

Improve thin areas of lawns in September/October by aerating, over-seeding and top-dressing with compost.

Fertilize lawns with “natural organic” or “slow release” fertilizer in September to develop healthy roots and crowd out weeds.

Reduce watering for cooler weather in September.

When rains come, shut off and drain watering systems.

Put away exposed soaker hoses, or re-cover with mulch if left out.

Clear out annual garden growth and compost it for spring. Keep pile as moist as a wrung-out sponge.
