Another Week of Hot Weather Ahead, and here's what your yard needs

Corvallis Oregon Yard Care: What to do in July

Manage your lawn Lawns want the most water now, when we have the least rain. It takes an inch of water a week to keep turf green, but if water is tight where you live, cut that amount in half. The lawn will fade to a straw color ― that’s summer dormancy ― but come back when shorter days, cooler nights, and fall rains kick in at summer’s end.

Remove suckers from apple and pear trees Because summer pruning doesn’t encourage as much regrowth as winter pruning, you can take off suckers (vertical sprouts that shoot up from horizontal limbs) now. Rub little ones out with your thumb, and nip bigger ones out with a knife, pruning shears, or saw.

Use water-saving containers To minimize the amount of time you need to spend watering, use pots that are at least 16 inches in diameter and made from something waterproof, like glazed terra-cotta, thick-walled plastic, fiberglass, or even metal. In dry years, avoid porous terra-cotta and wood. If the containers lack drain holes in the bottom, drill them or ask the seller to do that.

Compost everything Throw nonwoody plant parts (but no weed flowers) onto the pile as they become available, and turn and water the pile weekly.

Maintain fuchsias Bloom naturally slows down during the heat of summer, but you can extend it by faithfully deadheading, keeping plants regularly watered, and feeding monthly with complete fertilizer.

Mulch shrubs Nearly all woody plants and perennials benefit from a 3-inch layer of mulch applied this month. It keeps down weeds, conserves moisture, and gives feeder roots more organic matter to exploit.

Multiply bearded iris As foliage tips start turning brown, stop watering. Trim leaves back after they wither, then dig and divide rhizomes. Let them dry in the shade for a few days so that cut surfaces will callus, then replant in beds that have been weeded and amended (weeding iris beds during the growing season is difficult).

Prevent wormy apples Codling moth larvae (apple worms) and apple maggots destroy apples by tunneling through them. You can treat them organically by applying spinosad, which is made from a soil bacterium, Saccharopolyspora spinosa. It's sold as Success, Entrust, and Monterey Garden Insect Spray, and is widely available at nurseries.

Battle slugs The heat may chase them into hiding, but they’re there. A little bait in the cool spots will go a long way right now (as will night raids after lawn watering or summer showers; just handpick and throw them away). Put bait under stones, along the edges of walks, and near foundations. To protect pets and wild birds, place the bait in petproof slug traps or under boards held up by bricks.

Weed With a sharp hoe, slice the tops off small weed seedlings on a warm, dry morning, and let them lie where they fall. The sun will kill them by evening. Water deeply before you pull mature weeds so that taproots come out more easily
