Dig and Divide Mums
When chrysanthemums show signs of life, dig up and divide large plants. Discard woody portions and replant divisions 12 to 15 inches apart.
Clean Debris From Lawn Areas
Remove sticks, rocks, and other debris from your lawn to prevent damaging your lawnmower or injuring yourself when mowing. Check your lawnmower and other lawn care equipment in preparation for the coming season.
Prepare Beds For Planting
When the soil is dry enough to work, prepare your vegetable beds for later planting. You can plant out salad greens this month, along with spinach, chard, and other leafy vegetables. Watch out for slugs.
Help Nesting Birds
When birds are nesting they'll appreciate finding suitable construction materials. You can place short pieces of string, yarn, moss, etc. in net bags and hang them from tree limbs or lay them on the ground where the birds can easily find them. The more birds you attract to your garden, the fewer insects you'll have to deal with.
Rinse Away Spittle Bugs
While spittle bugs do very little damage, they are unsightly. If you find clusters of bubbles between the leaves and along the stems of your plants, simply wash them off with a strong jet of water.
