You can convert a swimming pool to a garden by draining safely, backfilling in lifts, and building healthy soil for new planting.
Thinking about turning a tired pool into a productive backyard plot? This guide shows you how to go from blue water to green growth with clear steps, simple tools, and checks you can finish over a few weekends at home.

Why Convert A Pool To A Garden
A garden can lower water bills, cut maintenance, and add fresh food. The shell area often has full sun, edges for seating, and a flat spot for beds. If resale is a concern, aim for tidy edges, clear paths, and a defined center.
How To Convert A Swimming Pool To A Garden: Full Method
1) Confirm Rules And Pick An Approach
Call your local building office to ask about pool “removal,” “abandon in place,” or “demolition.” Many cities allow leaving parts of the shell if you punch drainage holes and backfill to a compaction standard. Ask about inspections, hauling routes, and dust control. Mark utilities before digging and plan where soil and debris will go.
2) Power Down And Secure The Site
Shut off breakers to pumps and lights. Cap any gas lines to heaters. Lock gates and set signs while work is active. Stage tarps, plywood for wheelbarrow ramps, and a bin for metal, tile, and concrete.
3) Drain The Pool The Right Way
Chlorinated water harms fish and streams if dumped to the street. Many areas classify that release as an illicit discharge to the storm system. The safer route is to neutralize chlorine, verify pH, and send water to a sanitary sewer cleanout if your city allows it. Check your city page or the EPA MS4 guidance for the logic behind these rules.
4) Break Drainage Holes In The Shell
Use a rotary hammer or small breaker to make 12–18 inch holes through the pool floor and at the base of deep walls. Space holes a few feet apart. This prevents a bathtub effect and lets rain soak away under the fill. Wear eye and ear protection and keep a helper clear during chipping.
5) Backfill In Lifts So The Ground Doesn’t Sink
Fill with crushed rock or clean fill in 8–24 inch layers, wetting and compacting each lift. Aim for a firm base before you add topsoil. If you plan to set a patio or shed later, compact more tightly under those footprints. Simple plate compactors from rental shops work well for small jobs.
6) Shape Surface Grades And Paths
Set a gentle slope away from buildings. Use string lines to check grade. Keep paths wide enough for a wheelbarrow and lay weed fabric under gravel paths if needed. Edge beds with stone, brick, or timber to keep soil where it belongs.
7) Test Soil And Build Healthy Beds
New fill rarely has balanced nutrients. Take a soil sample and send it to a lab for pH, organic matter, and macro/micronutrients. Then amend with compost and minerals to match the report. A practical target for raised beds is a 50/50 mix of screened topsoil and mature compost. For help with sampling and labs, see this university soil testing guide.
8) Choose A Garden Type That Fits The Space
Sun-drenched rectangles invite vegetables, herbs, and fruit. Deep ends suit small trees or a wildlife border. Shallow ends shine with low beds and seating. The deck can hold containers, a potting table, or a rain barrel.
9) Install Water-Wise Irrigation
Drip lines fed by a pressure-regulated timer give steady moisture with less waste. Bury mainlines under paths and use shutoff valves for each bed. Add a filter to protect emitters from grit. A moisture meter saves water.
10) Plant, Mulch, And Monitor
Set transplants at the same depth they grew in pots. Water them in, then blanket the soil with 2–3 inches of organic mulch. Watch for settling during the first rainy season and top up soil where needed.
Safety And Timing Tips
- Work in dry weather so trenches and fill stay stable.
- Keep kids and pets out of the work zone.
- Rent smart: breaker, compactor, wheelbarrows, ramps, and a laser level speed the job.
- Plan debris hauling midweek to avoid weekend dump lines.
Taking A Pool And Turning It Into A Garden – Rules, Soil, And Steps
Many searchers type “taking a pool and turning it into a garden.” This section shows that path, while using the exact phrase how to convert a swimming pool to a garden naturally.
Permits And Inspections
Ask your city whether compaction tests or geotechnical letters are needed if a future building pad or driveway might sit over the old pool. Some places need inspections before backfill and again at final grading.
Dechlorination In Plain Terms
Neutralize chlorine with time in the sun or a dechlorination agent, confirm zero free chlorine with a test kit, and match pH to your sewer’s target range. Many utilities post simple rules on their websites tied to state and federal storm programs.
Raised Beds Over A Former Pool
Raised beds warm up fast and give steady yields. Fill frames with a balanced blend of compost and soil, then top up each season. Keep beds under four feet wide so you can reach the center without stepping on the soil.
Smart Planting Ideas For Former Pool Sites
Full-Sun Vegetable Layout
Use the long axis for rows or 4×8-foot beds. Keep heat-lovers on the warm side, greens and roots on the cooler side. Add trellises for summer vines.
Fruit And Pollinator Border
Ring the space with blueberries, rosemary, sage, and native flowers. Pop in a dwarf citrus or apple near the old deep end if your climate allows. Include a shallow bird bath with a small bubbler to keep water moving.
Low-Care Herbs And Perennials
Thyme, oregano, chives, echinacea, and yarrow form a tough mix that feeds pollinators and asks little from you. Clip and dry herbs right from the deck.
Common Mistakes To Avoid
- Dumping chlorinated water to a street drain.
- Skipping shell perforations, which traps water under fill.
- Filling the cavity in one go without compacting lifts.
- Planting before a soil test.
- Leaving low spots that collect water and invite mosquitoes.
Budget, Labor, And Timeline
A modest DIY “abandon in place” conversion with rented tools and local fill can land in the low thousands. Hiring a contractor for full removal and export costs more, yet it clears the space for future hardscape or a small structure. Most DIYers finish in two to six weekends, then plant by season.
Quick Reference: Soil Mixes And Uses
| Mix | Blend | Best For |
|---|---|---|
| Raised Bed Blend | 50% screened topsoil + 50% compost | Vegetables, herbs |
| Four-Season Bed | 40% topsoil + 40% compost + 20% leaf mold | Greens, roots |
| Fruit Shrub Base | 60% topsoil + 30% compost + 10% bark fines | Blueberries, currants |
| Dry Border | Sandy loam with grit and compost | Lavender, sage |
| Seed-Starting Top-Up | Sifted compost and fine topsoil | Top-dressing rows |
| Tree Pocket | Native soil loosened + compost ring | Dwarf fruit trees |
| Path Base | 3–4 inches compacted gravel | Stable, dry paths |
Mosquito And Water Management
Don’t let water stand in low spots, buckets, or saucers. Empty and scrub containers weekly during warm months. Keep birdbaths moving with a small bubbler or drop in BTI dunks where motion isn’t possible.
Seasonal Care After The Build
First 3 Months
Watch for settling and add soil where grades sag. Keep mulch topped up. Check irrigation lines and retighten fittings as the soil firms.
Months 4–12
Top-dress beds with compost. Plant a cover crop after heavy harvests to feed soil life and hold moisture. Prune fruit shrubs in the right season and refresh trellis ties.
Printable End-Of-Project Checklist
- I verified permits and inspections.
- I dechlorinated and drained to the approved location.
- I opened drainage holes in the shell.
- I backfilled and compacted in lifts.
- I shaped grades and set paths.
- I tested soil and amended by the report.
- I installed drip irrigation and mulch.
Can You Reverse The Project Later?
If you “abandon in place,” keep a record of shell location, fill type, and compaction steps. That log helps an engineer judge loads should a patio or studio be planned later.
Final Word: A Clear Path From Pool To Produce
Now you know how to convert a swimming pool to a garden and turn a maintenance sink into a lively, edible space. Start with the rules, make it safe, drain the right way, build soil, and plant for sun and season. The result is a tidy yard that feeds people and pollinators while giving you a calm place to sit with a basket.
