As spring approaches, Portland gardeners are gearing up for another season of planting, growing, and reaping the rewards of their outdoor spaces. But gardening in 2025 isn’t just about beautiful landscapes—it’s about sustainability, resilience, and working with nature rather than against it. Whether you’re an urban gardener with a small space or managing a sprawling backyard, incorporating eco-friendly practices into your garden will not only benefit the planet but also create a thriving, low-maintenance oasis for years to come.
So, what are the top sustainable gardening trends for Portlanders this year, and how can you implement a few small actions to create BIG ecological impact in your own garden? Let’s dig in.
1. Foodscaping: The Blend of Beauty & Function
Gone are the days of purely ornamental landscapes. Foodscaping—integrating edible plants into traditional landscapes—is gaining traction in Portland. Instead of a thirsty, high-maintenance lawn, many homeowners are swapping in perennial vegetables, herbs, and fruit trees that not only provide food but also attract pollinators and support local biodiversity. If you see me mention “ecological” gardening on my website or social media, this is a form of that. A garden that benefits people (growing food and medicine) and planet (supports pollinators and native habitat) is an ecological garden. If you're new to the idea of foodscaping, I recommend checking out Custom Foodscaping out of St. Louis, Missouri. They are great teachers and mentors on this subject and host an annual Foodscapers Summit that is packed with info about foodscaping.
How to Get Started:
Swap out purely decorative shrubs for berry bushes or edible flowers like nasturtiums and calendula.
Replace sections of your lawn with drought-tolerant herbs like thyme, oregano, and rosemary.
Plant fruit trees strategically to provide shade and create microclimates for other edible plants.
Incorporate edible ground covers like strawberries to suppress weeds and provide food.
Portland’s Climate Advantage: Oregon’s mild climate allows for year-round edible landscaping. By selecting the right plants for each season, gardeners can maximize their harvest and reduce reliance on store-bought produce.
Pro Tip: Consider layering plants using the permaculture concept of “stacking functions.” For example, plant deep-rooted fruit trees, shade-loving perennials, and nitrogen-fixing ground cover together for a self-sustaining mini-ecosystem.
2. Compost is King: Closing the Loop on Waste
Sustainable gardening starts with the soil, and there’s no better way to build healthy soil than through composting. With Portland’s push towards waste reduction, home composting is becoming an essential practice for gardeners who want to cut down on food waste while boosting their garden’s fertility naturally.
Composting Tips:
Start small with a simple backyard bin or a worm composting system for smaller spaces.
Layer green materials (food scraps, grass clippings) with brown materials (leaves, cardboard) for a balanced mix.
Use finished compost to enrich garden beds, boosting soil structure and moisture retention.
Avoid adding diseased plants or invasive weeds to your compost to prevent issues in your garden.
Did You Know? According to the Oregon Department of Environmental Quality, food waste makes up nearly 30% of landfill waste in the state. Composting can significantly reduce this impact and help return valuable nutrients to the soil.
Bonus Tip: Portland offers curbside composting, but keeping some food waste for your home compost can improve your soil and reduce reliance on municipal waste systems.
3. Water-Wise Gardening: Adapting to a Changing Climate
Portland’s weather can be unpredictable, and with hotter, drier summers on the rise, water conservation is more important than ever. Designing your garden with drought tolerance in mind not only saves resources but also ensures your plants can thrive even during dry spells.
Water-Saving Strategies:
Plant native and drought-resistant species like yarrow, lavender, and Oregon grape.
Use mulch to retain moisture and reduce evaporation.
Install drip irrigation or soaker hoses to deliver water directly to plant roots, minimizing waste.
Collect rainwater using barrels to reduce dependence on municipal water sources.
Create a rain garden! EMSWCD has great free resource videos on their website!
Fact: The City of Portland offers rebates for homeowners who install water-efficient irrigation systems and rain gardens to help conserve water.
Deep Dive: Research shows that drip irrigation can reduce water use by up to 50% compared to traditional sprinklers. With rising summer temperatures, making this switch can save both water and money.
Expert Insight: A study from Oregon State University found that mulching can reduce soil moisture loss by 25-50%, making it one of the simplest ways to conserve water in the garden.
4. Wildlife-Friendly Gardens: Supporting Pollinators & Birds
A sustainable garden isn’t just for humans—it’s a sanctuary for birds, bees, and beneficial insects. Creating a habitat-friendly garden can increase biodiversity and reduce the need for chemical interventions. Portland has a program called Backyard Habitat Certification that is a wonderful resource to help you “rewild” your yard, and help create food, shelter, and habitat for local insects, birds, amphibians, and mammals by creating “naturescapes” around your yard filled with native plants. There is a very specific list of “Portland” native plants you'll need to choose from to get your Backyard Habitat Certification, but adding Oregon natives, and even PNW natives is also a great way to support local animals and pollinators. This is also an example of “ecological” gardening. Some of my favorite places to source local, native and ecologically friendly plants are Symbiop, Echo Valley Natives, Sauvie Island Natives, Bosky Dell Natives, and Bloomsday Natives.
Simple Ways to Support Wildlife:
Plant a variety of flowers that bloom throughout the seasons to provide continuous nectar sources.
Leave some areas “wild” with native plants and brush piles for shelter.
Provide a water source like a shallow dish or birdbath to support local wildlife.
Avoid pesticides that can harm pollinators and beneficial insects.
Planting native plants throughout your garden and densely in “naturescaped” areas specifically created to support native wildlife.
Portland’s Pollinators: The Western bumblebee, once common in the Pacific Northwest, has seen a population decline of over 90%. Planting native wildflowers and eliminating pesticide use can help these essential pollinators recover.
Additional Tip: Consider joining Pollinator Pathway Portland, a local initiative encouraging residents to create connected corridors of pollinator-friendly gardens.
5. Seasonal Gardening: Planning for Year-Round Harvests
One of the best ways to ensure a productive and sustainable garden is to plan for year-round growing. With Portland’s mild climate, you can grow food in every season by staggering plantings and choosing cold-hardy crops for the winter months.
Garden Planning Tips:
Start seeds indoors now for warm-weather crops like tomatoes and peppers.
Succession plant quick-growing crops like radishes and lettuce to extend harvests.
Use row covers and cold frames to keep greens growing through fall and winter.
Choose cold-hardy crops like kale, leeks, and Brussels sprouts to enjoy fresh produce all winter.
Pick up some perennial plants to add to your garden to enjoy not only year-round food, but multi-year food that requires little maintenance once established. Some examples are asparagus and rhubarb.
Did You Know? Portland’s growing season averages over 200 days, making it one of the most productive urban gardening climates in the U.S. There isn’t a single day of the year my sustainable garden isn’t producing SOME sort of food or medicine for me. We’re so lucky to live and garden in Portland (sorry other cities!).
Additional Tip: Investing in a greenhouse or simple hoop house can extend your growing season even further, allowing you to cultivate fresh greens all winter long.
6. Regenerative Gardening: Beyond Sustainability
Sustainability is great, but regenerative gardening takes it a step further—actively improving soil, water cycles, and biodiversity over time.
Regenerative Practices:
Rotate crops to prevent soil depletion and reduce pests.
Practice no-till gardening to protect soil structure and increase carbon sequestration.
Grow cover crops like clover and vetch to naturally enrich the soil with nitrogen.
Use biochar to improve soil fertility and capture carbon (stay tuned for a blog post on this soon!).
Research Insight: Studies show that regenerative agricultural practices can increase soil organic matter by up to 40%, leading to healthier plants and greater yields.
Actionable Step: Start small—choose one regenerative practice to implement this season and build from there.
