Raised Bed Garden Design for Small Yards: Maximize Your Harvest in Any Urban Space
Even in the smallest city yard, a productive raised bed garden is absolutely possible - with the right layout. In fact, when space is tight, raised bed garden design for small yards becomes everything. Knowing how to plan your raised beds for productivity, ease of access, and long-term soil health can make the difference between a garden that thrives and one that fizzles out by midsummer.
Whether you’re in Seattle, Portland, or anywhere in the Pacific Northwest, this guide will walk you through how to design a raised bed garden that works with your space - and your lifestyle.
1. Start With the Sun ☀️
In the PNW, we have a generous growing season, but light levels vary. Before placing any beds, observe your yard for a few days - especially in spring and early summer.
✅ Look for 6 to 8 hours of direct sunlight. Leafy greens can tolerate partial sun, but tomatoes, squash, and peppers need full sun.
🧭 Pro tip: Orient beds north to south whenever possible. This reduces shading and ensures even sun exposure throughout the day.
2. Choose Bed Dimensions That Fit Your Space (and Body) 📏
In urban yards, rectangular raised beds (3 to 4 feet wide and 6 to 8 feet long) are usually ideal.
📏 Why this works:
3 to 4 feet is the perfect width to reach from either side without stepping on the soil.
6 to 8 feet is long enough to grow a lot - but still manageable.
🧱 Height matters too: In wetter PNW winters, 10 to 12 inch beds improve drainage and warm up faster in spring.
3. Plan for Pathways 🧱
It’s tempting to pack in as many beds as possible, but don’t skip pathways! Good spacing means you’ll actually enjoy working in the garden.
🚶♀️ Leave at least 18 to 24 inches between beds for walking, weeding, and harvesting. If you're using a wheelbarrow, plan for 36 inches.
🌱 Bonus tip: Add stepping stones or wood chips to suppress weeds and improve drainage in high-rain zones.
4. Map Your Crops by Height and Timing 📆
A productive layout means thinking ahead - not just about what you’re growing, but when and how tall those crops get.
📋 Use these principles:
Tall plants (tomatoes, trellised cucumbers, pole beans) go on the north side so they don’t shade others.
Succession plant short-season crops like radishes, lettuce, and spinach. Harvest and replant!
Group by water needs. Keep thirsty crops like cucumbers, lettuce, and squash together.
5. Add a Touch of Perennial Structure 🌿
Even in a seasonal raised bed garden, a few perennial herbs (like thyme, oregano, or chives) anchor the space and reduce replanting. Add these to the corners of beds or tuck them near your garden’s edges.
🦋 Bonus: They attract pollinators and beneficial insects!
Example: Small Urban Layout for the PNW
Let’s say you have a 10 x 15 foot yard in Seattle. Here's one smart layout:
Two 3 x 8 beds, running north–south with 24" between
1-foot wood chip path around all sides
One vertical trellis on the north end for climbing peas in spring, replaced by beans in summer
Herbs (thyme, parsley, chives) in a corner planter or pot
Salad greens rotated every 3 weeks in half a bed
Tomatoes staked on the southern end of the second bed
Simple, compact, and surprisingly productive!
