Happy Earth Day! 5 easy ways to celebrate

Helping the planet starts in our own space

I like to think that the readers of this blog are planet-aware enough to already be using earth-friendly practices with their plants and with their gardens.

So let's celebrate Earth Day today by encouraging family, neighbors or friends to try one of these easy ways to help battered old Mother Earth:

-- Compost. All those kitchen scraps and fallen leaves that end up in the green waste or (horrors!) the trash bin could be working right at home. It really doesn't take much to create the "garden gold" that enriches the soil, just organic matter, water and air. Share this composting guide .

And if someone doesn't have space for a compost bin, they can try worm composting. Worms just need a big plastic bin and some bedding material, and they'll happily transform those potato peelings and apple cores into worm castings, which are MAGIC in the garden. Here's my blog post from last fall about my worm bin. (Those red wigglers are still going strong, by the way). And here's the Sacramento County master gardeners' guide to setting up a worm bin.

-- Feed the soil. That compost? Best thing a gardener can add to problem soil. It will help lighten clay and provide structure to sand, in addition to improving the soil's water-holding capacity. That in turn helps plants send out better, stronger roots. Worm castings spread over the top of the soil will leach down and improve it, too. Helping the soil always is a win-win proposition.

-- Plant something for the beneficials. Urban life is tough on all the small but important insects that make the outdoor world work, such as hoverflies, lacewings, damsel bugs and parasitic mini-wasps.And the rock star of the group, lady beetles. Many of them dine voraciously on the "bad bugs" -- so much better than using insecticides. So add to the garden some plants that give these little insects food and resting spots.  Suggestions: Flowering herbs, cosmos, yarrow and goldenrod. See this list for more ideas.

-- Switch to natural fertilizers. Fertilizers are confusing to most people, so they grab whatever seems right, whatever the source. But one of the most important things I learned last year in master gardener classes is that while plants themselves don't care where their nutrients come from, the soil will care immensely . Chemical fertilizers boost the plants -- sometimes too much -- but do little to aid the soil or the microorganisms that live there. Look for fertilizers based on natural ingredients such as fish emulsion, alfalfa meal, chicken manure, blood meal and cottonseed meal. (I'm now one of those people who stands in the nursery aisle reading package ingredients.)

-- Plant a tree. It's an Earth Day cliché, but that's because it's true. Trees clean the air, anchor the soil, give shelter to birds and other wildlife, and provide shade to homes and gardens. Even a small one helps.  The Sacramento Tree Foundation would be happy to help anyone choose the right tree .

Bonus way to celebrate that anyone can do: Take 5 minutes to discover something new in your garden. Explore the shapes of the oak leaves or marvel at the color gradations in a flower petal. It's an astonishing world and we are so lucky to be its caretakers.

Dig In: Garden checklist for week of Sept. 25

This week's warm break will revive summer crops such as peppers and tomatoes that may still be trying to produce fruit. Pumpkins and winter squash will add weight rapidly.

Be on the lookout for powdery mildew and other fungal diseases that may be enjoying this combination of warm air and moist soil.

* Late September is ideal for sowing a new lawn or re-seeding bare spots.

* Compost annuals and vegetable crops that have finished producing.

* Cultivate and add compost to the soil to replenish its nutrients for fall and winter vegetables and flowers.

* Plant for fall now. The warm soil will get cool-season veggies and flowers off to a fast start.

* Plant onions, lettuce, peas, radishes, turnips, beets, carrots, bok choy, spinach and potatoes directly into the vegetable beds.

* Transplant lettuce, cabbage, broccoli, kale, Brussels sprouts and cauliflower.

* Sow seeds of California poppies, clarkia and African daisies.

* Transplant cool-weather annuals such as pansies, violas, fairy primroses, calendulas, stocks and snapdragons.

* Divide and replant bulbs, rhizomes and perennials.

* Dig up and divide daylilies as they complete their bloom cycle.

* Divide and transplant peonies that have become overcrowded. Replant with "eyes" about an inch below the soil surface.
