## Filling Your Raised Beds
Proper soil mix ensures healthy plants and optimal drainage in raised bed gardens.
### Soil Mix Recipes
**Basic Mix (1 cubic yard):**

– 1/3 compost: $25-35
– 1/3 peat/coir: $15-25
– **Total cost:** $60-90 per cubic yard

– 10% perlite or vermiculite
– Amendments: lime, fertilizer
**Square Foot Mix (Mel’s Mix):**
– 1/3 compost blend (5+ sources)
– 1/3 peat moss or coir
– 1/3 coarse vermiculite
– Cost: $80-120 per cubic yard
### Calculating Soil Needs
**Volume Formulas:**
– Rectangular: L × W × H (in feet) × 7.5 = gallons
– Circular: π × r² × H × 7.5 = gallons
– Cubic yards: Gallons ÷ 202
**Coverage Estimates:**

## Frequently Asked Questions
**What’s the best wood for raised beds?**
Cedar and redwood naturally resist rot for 15-20 years. Untreated pine lasts 3-5 years but costs 50-70% less. Never use pressure-treated lumber from before 2004 for food gardens.
**How deep should raised beds be?**
Minimum 6-8 inches improves drainage. Standard 12 inches suits most vegetables. Root crops and perennials benefit from 18-24 inches. Consider 30+ inches for accessibility.
**Is building raised beds physically demanding?**
Yes, it involves lifting heavy materials (lumber 40-60 lbs, soil bags 40 lbs), bending, kneeling, and using power tools. Plan for helpers if you’re over 50 or have physical limitations. Take frequent breaks and don’t attempt to finish in one day.
**Do raised beds need a bottom?**
Usually no—open bottoms allow drainage and deep root penetration. Add hardware cloth only if you have burrowing pests. Elevated beds require bottoms with drainage.
**What’s the ideal raised bed width?**
Maximum 4 feet allows reaching the center from either side. 3 feet works better for children. Accessible beds should be 2 feet wide for wheelchair reach.
**How much soil do I need?**
Calculate length × width × depth in feet, multiply by 7.5 for gallons, or divide by 27 for cubic yards. A 4×8×12″ bed needs approximately 1 cubic yard.
**Should I line my raised beds?**
Line only the sides with plastic to prevent wood rot. Never line the bottom—this prevents drainage. Use landscape fabric only for weed control with drainage holes.
**How long do raised beds last?**
Cedar/redwood: 15-20 years. Pine: 3-5 years. Composite: 25+ years. Metal: 20-30 years. Stone/masonry: 50+ years. Regular maintenance extends all lifespans.
**Can I put raised beds on grass?**
Yes, but remove grass first to prevent regrowth. Lay cardboard as a barrier, then add your soil mix. The cardboard decomposes naturally while blocking weeds.
**What are realistic costs for a complete raised bed garden?**
For 3-4 beds with soil, expect $500-1,200 total investment depending on materials and your location. Urban areas typically cost 30-50% more. Don’t forget tools if you don’t own them (add $100-200).
**What’s the best orientation for raised beds?**
North-south orientation provides even sun exposure. East-west works if you plan crops by height. Consider prevailing winds and existing shade patterns.
**How do I prevent soil from washing out?**
Ensure beds are level, use proper soil mix with good structure, mulch the surface, and avoid overhead watering. Install edges 1 inch above soil level.

## Conclusion
Building DIY raised garden beds transforms your growing space while providing better drainage, soil quality, and accessibility. Whether you choose simple wood frames, durable metal designs, or permanent stone structures, these 20 designs offer solutions for every budget and skill level.
The key to success lies in careful planning, quality materials appropriate for your budget, and proper construction techniques. Start with one or two beds to develop your skills and expand as you gain experience and see results.
Most gardeners recover their investment within the first growing season through increased productivity and reduced grocery costs. Beyond financial benefits, raised beds provide easier maintenance, better pest control, and the satisfaction of creating a productive garden space.
Focus on function first—even the simplest raised bed dramatically improves growing conditions compared to ground-level gardens. Add features and expand your system as time and budget allow.
