Don't forget to water evergreens in the winter if you live in an area with little winter precipitation.
If you have a live Christmas tree, recycle it by cutting branches off and laying them in flower beds for mulch and bird cover.
A golf tee makes an inconspicuous marker for bulbs. Place one when you plant so you'll know where to expect them to pop up.
Add compost to the flower beds during the fall before you plant. Top dress with more after you plant, and you'll need to water less.
Cut yew and holly branches and stick them into planters in the fall after the annuals have faded away. Sometimes you'll get lucky and they'll take root!
Recycle your gardening catalogs and magazine at nursing homes and doctors' offices. The pretty pictures bring far more joy than outdated magazines.
Leave seed heads on grasses over the winter. The birds will appreciate it.
Drain and wind up your hoses before the first freeze. Store them indoors and they'll last longer.
Water early or late in the day, but not in full sun in the heat of the day.
