Sacramento Leaf Season brings avalanche of garden gold

Don't just rake and toss; fallen leaves make great mulch and compost

In the City of Trees, October is either a time of dread or opportunity. It's Sacramento Leaf Season.

Every puff of breeze brings down more leaves as our urban forest sheds its foliage. While evergreens keep their needles, deciduous trees such as birches, sycamores and elms seem to rain down golden leaves.

That fall foliage looks pretty up on its branches. Off the tree, it's a mess.

Instead of an avalanche of green waste, think of it as garden gold. Smaller leaves make excellent mulch; just rake and place 2 to 3 inches deep around trees and shrubs.

Or chop larger leaves with a lawn mower (a couple of passes usually is sufficient) and use as mulch. It will last through the winter, keeping down weeds while retaining even soil moisture.

That's what nature does with its fallen leaves. They decompose around the trees, revitalizing the soil while protecting tree roots.

Bill Maynard, Sacramento's community garden coordinator, recommends using fallen leaves for making compost.

"Brown" ingredients are necessary to make good compost, Maynard explained. He uses the lasagna method of compost making, layering green materials such as freshly cut grass or spent vegetable plants with "browns," such as dried leaves. That helps create an environment for rapid breakdown of the bin's ingredients into usable compost.

"You need browns in compost," he said. "Those are usually dried leaves or straw bales." The leaves don't require a trip to the feed store.

Besides adding nutrients, the brown ingredients serve another important role.

"Always top the compost with a brown layer," Maynard said. "That keeps flies down."

Maynard sets aside bags of dried leaves for later use in spring when brown material is scarce. "You need brown material year round for composting," he said. "In the spring, you have lots of green but no brown. So, save some leaves."

Those heaps of leaves now represent future fertilizer and potential savings. Go ahead and fall!

Garden Checklist for week of May 19

Temperatures will be a bit higher than normal in the afternoons this week. Take care of chores early in the day – then enjoy the afternoon. It’s time to smell the roses.

* Plant, plant, plant! It’s prime planting season in the Sacramento area. If you haven’t already, it’s time to set out those tomato transplants along with peppers and eggplants. Pinch off any flowers on new transplants to make them concentrate on establishing roots instead of setting premature fruit.

* Direct-seed melons, cucumbers, summer squash, corn, radishes, pumpkins and annual herbs such as basil.

* Harvest cabbage, lettuce, peas and green onions.

* In the flower garden, direct-seed sunflowers, cosmos, salvia, zinnias, marigolds, celosia and asters.

* Plant dahlia tubers. Other perennials to set out include verbena, coreopsis, coneflower and astilbe.

* Transplant petunias, marigolds and perennial flowers such as astilbe, columbine, coneflowers, coreopsis, dahlias, rudbeckia and verbena.

* Keep an eye out for slugs, snails, earwigs and aphids that want to dine on tender new growth.

* Feed summer bloomers with a balanced fertilizer.

* For continued bloom, cut off spent flowers on roses as well as other flowering plants.

* Don’t forget to water. Seedlings need moisture. Deep watering will help build strong roots and healthy plants.

* Add mulch to the garden to help keep that precious water from evaporating. Mulch also cuts down on weeds. But don’t let it mound around the stems or trunks of trees or shrubs. Leave about a 6-inch to 1-foot circle to avoid crown rot or other problems.
