4. Create your own plant swap
Ask your neighbors if they’re interested in a plant swap. If they’ve been to the nursery, they may have more vegetable plants than they need, and perhaps they’d like to swap you for some onion starts or that lion’s tail, marjoram or cilantro that came up on its own.
5. Try lasagna mulching
Maybe you’re not ready to rip out your lawn, but here’s a chance to start slow and easy by converting a section of lawn into a garden bed via lasagna mulching. All you need is a pile of corrugated cardboard (flattened boxes are best), about double what you think you’ll need to create your space. The cardboard is candy to beneficial mycorrhizal fungi that help plant roots find the nutrients and water they need, according to interpretive horticulturist Leigh Adams, who created the Los Angeles County Arboretum’s Crescent Farm, lush with edible trees, plants and wildflowers. Lay down the cardboard thickly, water it well, tamping it against the ground, then add at least 8 inches of compost, organic potting soil, dried leaves, vegetable trimmings, garden waste (minus weed seeds), lawn clippings (in moderation to avoid matting) and/or wood chips from local tree trimmers. Water each layer and cover with at least 4 inches of mulch. If all you have is wood chips, make them at least 8 inches deep, and when you plant, fill your holes with potting soil to give seedlings a base to get started as the pile breaks down, ultimately becoming excellent soil.
6. Enrich your garden soil
Feed your garden bed with bags of organic potting soil, compost, aged steer manure or other organic amendments. Water it well, then let it sit for a week or two while the organisms break down the ingredients and “cook.” Give this mix a week or two to cool down, since planting right away could “burn” or kill tender seedlings.
7. Set up some deep watering stations
Prepare deep watering stations in your vegetable garden. Master gardener Yvonne Savio, creator of the GardeninginLA.net blog, suggests burying 5-gallon nursery buckets (the kind with the holes in the bottom) until the top rises just 4 inches above the ground. Plant around those buckets this spring, and as the heat rises, fill the buckets once or twice a week with water. Deep watering will send roots deeper into the ground, where they’re more likely to thrive when the weather gets hot.
