“The Part of Tens” is a classic For Dummies feature, and Chapter 23 delivers ten high‑impact, low‑cost projects that offer the fastest return on investment – both financially and ecologically.
Here are Dell’s top ten:
Plant a shade tree on the south or west side of your house. Cuts cooling bills by 15‑30%. Payback: 3‑5 years.
Install a rain barrel. Free water for your garden. Payback: one season.
Convert a sprinkler zone to drip irrigation. Saves 50‑80% of water on that zone. Payback: 6 months.
Sheet mulch a section of lawn to convert to a native plant bed. Eliminates mowing, fertilizing, and watering. Payback: immediate (time savings) plus long‑term water savings.
Build a compost bin (from pallets or wire mesh). Turns yard waste and kitchen scraps into free soil amendment. Payback: less than a year.
Install a programmable smart controller for your irrigation. Saves 20‑50% of outdoor water. Payback: 1‑2 years.
Replace a gas mower with a reel mower (push mower) or cordless electric. Zero emissions, no gas cost. Payback: 2 years (reel mower) or 3‑4 years (electric).
Start a vegetable garden (just 100 square feet). Produces $500‑$1,000 of organic produce per year. Payback: first season.
Remove a water‑hogging lawn and replace with climate‑appropriate plants. Saves 30,000‑60,000 gallons per year for a typical suburban lawn. Payback: 2‑5 years depending on water rates.
Add a 3‑inch layer of mulch to all your planting beds. Reduces watering needs by 25‑50%, suppresses weeds, and feeds soil. Payback: immediate.
Dell encourages readers to pick just one or two projects to start. The cumulative effect of small actions is huge.
