Get Your Garden Spring-Ready: 5 Simple Tips [gallery link="none" ids="1163,17443,2043"] Spring is the perfect season to take action in your yard or community green space. Whether you’re a seasoned gardener or just starting out, here are a few tips from our team to help your garden thrive: Prep Your Soil: Loosen the ground and give it a good soak before planting. This helps roots settle in and access nutrients more easily. Choose Natives: Native plants are adapted to local conditions, support pollinators, and often require less maintenance and water. Tame the Invasives: Remove or reduce invasive species early in the season before they take hold. It’s a simple way to give native plants room to grow. Tickle Those Roots: When transplanting plugs or potted plants, gently loosen the roots. It helps the plant establish itself faster. Water Deeply: Give new plantings a thorough watering to help them recover from transplant shock and get settled in their new home. Looking for more tips?

Tasks like weeding, pruning, and loosening the soil support strong root systems, encourage healthy growth, and help maintain a thriving, sustainable garden ecosystem. Recognizing the garden's significance and the value of collaboration, our team united to accommodate and nurture this year's growth.
Feeling inspired? Organizing a gardening day is a fun, low-cost way to give back to your environment and bring people together. Celebrate Earth Day 2025 by starting a garden, volunteering with a local environmental group, or organizing your own mini planting day with friends, family or coworkers.
Rain gardens are a beautiful, low-maintenance green infrastructure solution for managing stormwater, reducing erosion, and improving water quality by filtering pollutants before they reach local waterways. They also provide valuable habitat for pollinators and other beneficial wildlife.
Princeton Hydro President Geoffrey M. Goll, P.E. led a free public workshop on how to build a rain garden of your own. Hosted in Yardley, PA by the Lower Makefield Township Environmental Advisory Council as part of their Environmental Lecture Series, the session offered practical, approachable guidance for managing stormwater at home.
Using photos from his own yard, Geoffrey walked attendees through how he designed and installed a rain garden to reduce runoff and eliminate pooling water. He shared ten easy-to-follow tips and answered questions on plant selection, drainage strategies, long-term maintenance, and when and why to amend soil before planting.

The real spirit of Earth Day lies in our ongoing commitment to care for the natural world, not just once a year, but in everyday choices and community actions. As Geoffrey quoted in his rain garden presentation, "Small acts, when multiplied by millions of people, can transform the world." – Howard Zinn.
Each July, we take time to reflect on the beauty, value, and importance of lakes during Lakes Appreciation Month. Since 1998, this national initiative founded by the North American Lake Management Society (NALMS) has encouraged communities to get outside, engage with their local waterbodies, and take action to protect them.
This year, we’re sharing four simple and meaningful ways to celebrate. If you're a lake regular or you're just starting to dip your toes into lake stewardship, you'll find something valuable here!
There’s no better way to appreciate your local lake than by exploring it up close. Take a morning paddle, enjoy a peaceful shoreline walk, or head out with a fishing rod and a friend. Lakes offer the perfect setting for adventure, reflection, and connection with nature. Whether it’s your first visit or your hundredth, there’s always something new to discover and appreciate at your local lake.
And thanks to digital tools, exploration doesn’t stop at the water’s edge. For example, in Pennsylvania, the Bucks County Conservation District, in collaboration with Bucks County Planning Commission and Princeton Hydro, recently launched an interactive ArcGIS StoryMap showcasing the Lake Luxembourg watershed and Conservation Pool Restoration Project. This interactive tool lets you experience the lake’s ecology in a whole new way. Take a deeper dive—without getting your feet wet—and check out the StoryMap here.
Join lake lovers across North America for the annual Secchi Dip-In, a citizen science event where volunteers collect water clarity data using a simple Secchi disk. This collective initiative helps monitor lake health over time and contributes valuable data to local lake managers and the broader scientific community.
Getting involved is simple—grab a Secchi disk, take a turbidity reading, and submit your data online using the Secchi Dip-in database. Need guidance on how to use a Secchi disk? Check out our instructional video for a step-by-step walkthrough:
Get creative and let your appreciation for lakes shine. Try your hand at Lakes Appreciation Month Bingo, make a short video, write a lakeside haiku, or paint a scene from your favorite shoreline. When you express your love for lakes through art, you can also inspire others to connect with and care for their local lakes.
You can also participate in the NALMS “Show Your Lakes Appreciation” Challenge. While you’re out enjoying your favorite lake, snap a #lakeselfie, capture a scenic sunset, or photograph your pet mid-paddle. Post your photo on your favorite social media platform with the hashtag #LakesAppreciation and include the name of the lake in your caption for a chance to win prizes and be featured online. The contest runs all month long!
Here's a winning entry from last year—a joyful shot of “Jo Jo the dog kayaking on Lake Michigan.”
Looking to make a tangible impact? Volunteer for a local lake cleanup, support your watershed association, or become a lake steward helping to monitor your lake's water quality, remove invasive species, and more! Even taking small actions in your own backyard, like reducing fertilizer use or installing a rain garden, can make a big difference for water quality.
Princeton Hydro has had the privilege of partnering with lake associations, municipalities, and nonprofit organizations across the country on a wide range of lake restoration and stewardship efforts. These partnerships show what’s possible when communities come together to invest in their lakes. Read about our recent collaboration with Smith Mountain Lake in Virginia.
Whether you’re picking up trash, attending a public meeting, or just learning more about lake science, your involvement matters.

Happy Earth Day! It's important that we all do our part today and every day to honor our precious planet, promote climate action, and support sustainability. We've put together a quick list of fun ideas and helpful tips to celebrate Earth Day 2024:
Rain gardens are a cost effective, attractive, and sustainable way to minimize stormwater runoff and filter out pollutants. This aesthetic, low-maintenance addition to any outdoor landscape creates a functioning habitat that attracts pollinators, beneficial insects, and birds. It can also help reduce erosion, promote groundwater recharge, and minimize flooding.
Princeton Hydro President Geoff Goll, P.E. and his family recently installed a rain garden at their home. They documented the process with photos and step-by-step instructions.
You can help conserve water usage by incorporating water-wise practices into your daily life. Installing a rain barrel is a great place to start! Using a rain barrel to collect fresh, free rainwater helps save money, conserve water AND protects the environment. Collecting water in rain barrels is a fun, affordable and effective way to reduce the amount of run-off flowing into storm drains and waterways. We’ve put together four simple steps to help you install a rain barrel in your yard.
Tulips are starting to emerge, buds are blossoming on trees and, unfortunately, invasive plant species are also beginning their annual growing cycle. Invasive species create major impacts on ecosystems near and far, but we can all do our part to reduce the spread.
Princeton Hydro Landscape Architects and Expert Green Thumbs Jamie Feinstein, RLA and Cory Speroff, PLA, ASLA, CBLP led a live “Ask Me Anything” Spring Gardening conversation via Facebook. They provided gardening tips and tricks, including:
You can play a major role in maintaining the health and safety of your community. By committing to a regular litter pick-up schedule, you can help keep your neighborhood cleaner and decrease the amount of debris and pollution entering your community waterways. Consider choosing a nearby park, lake, pond or stream for your trash clean-up activities. Whatever spot you choose, pick the place that's best for you, invite friends or family to join you, determine a regular clean-up schedule, and stick to it!
As biologists, ecologists, environmentalists, and outdoor enthusiasts, all of us at Princeton Hydro take our responsibility to care for and respect our natural surroundings very seriously. We play hard and work hard to protect our natural resources for generations to come. Happy Earth Day!
A volunteer effort, lead by the Middlesex County, New Jersey Parks and Recreation Department and the Rutgers Cooperative Extension, recently took place at Thompson Park.
Despite the rainy weather, 78 volunteers and members of the Youth Conservation Corps removed litter from the shoreline of Manalapan Lake, repaired fencing, made improvements to the park’s walking trails, weeded and mulched the park’s rain garden and native plant garden, and installed new plants in the rain garden.
The park’s rain garden was originally designed by Princeton Hydro Senior Water Resource Engineer Dr. Clay Emerson, PE, CFM. Rain gardens are cost effective, attractive and sustainable means to minimize stormwater runoff. They also help to reduce erosion, promote groundwater recharge, minimize flooding and remove pollutants from runoff.
By definition, a rain garden is a shallow depression that is planted with deep-rooted native plants and grasses, and positioned near a runoff source to capture rainwater. Planting native plants also helps to attract pollinators and birds and naturally reduces mosquitos by removing standing water thus reducing mosquito breeding areas.
Rain gardens temporarily store rainwater and runoff, and filter the water of hydrocarbons, oil, heavy metals, phosphorous, fertilizers and other pollutants that would normally find their way to the sewer and even our rivers and waterways.
On the day of the volunteer event, Central New Jersey received 0.44 inches of rain. "We got to see the rain garden in action, which was really exciting," said Princeton Hydro Senior Project Manager Kelly Klein, who volunteered at the event.
Volunteers from the following organizations participated:
The Middlesex County Parks and Recreation Department’s next public volunteer event is tomorrow (June 2) in Davidson’s Mill Pond Park.
The Princeton Hydro team has designed and constructed countless stormwater management systems, including rain gardens in locations throughout the Eastern U.S. Click here for more information about our stormwater management services.
