Growing something from the goodbye in Portland
By our estimate, around 25,500 households in Portland share their home with a dog or cat, and roughly 2,150 of those pets die each year. More of those families now ask about planting or water memorials. Here's how to do it well.
- Trees matched to Portland's climate
- Soil-safe planting method for ashes
- Real prices for bio urns and aquamation

Your living memorial options around Portland
Portland's salt air, snow and constant freeze-thaw swings are hard on outdoor keepsakes. Granite, a natural fit in a state with a long quarrying history, and cast bronze endure; painted wood and thin resin crack within a few winters. Hoping to plant a tree urn? Wait until May, when the ground has thawed and the soil has warmed enough for roots.
Plenty of Portland families release some of the ashes somewhere tied to the coast, such as a favorite stretch of Eastern Promenade shoreline or a quiet spot on one of the Casco Bay islands reached by ferry. Check the rules for public land first. Holding the remainder in an urn at home, or dividing it among relatives, is common too.
Small towns tend to have long memories, and a memorial tree in Portland is often planted with a lot of history around it: the same yard for decades, a family farm, a favorite fishing spot. If the land is likely to stay in the family, a long-lived native tree is a lovely choice. If it might be sold, consider a shrub bed, a portion of ashes kept back, or a water release that doesn't depend on who owns the ground in twenty years.
About 69,911 people live in Portland, which makes it the largest of the 13 Maine communities we cover.
Families in Portland often end up using a provider from South Portland (2 miles), Westbrook (6 miles) and Saco (12 miles). That is normal: crematories serve a radius, not a single town, and the drive is priced into collection.
Our estimate
25,500
Portland: dog- or cat-owning households, our estimate
How we calculated this
69,911 ÷ 2.5 = 27,964 households; × 53% (dog) + 39% (cat) = 25,500. Multi-pet homes count once.
Our estimate
2,150
dog and cat deaths per year in Portland, our estimate
How we calculated this
25,500 dog/cat-owning homes ÷ average lifespan (dog: 12.69 yrs + cat: 11.18 yrs) ≈ 2,150 a year. A floor, not a ceiling.
53%[1]
53% of US households own a dog, which is about 71 million households.
12.69 years[2]
US dogs have an average life expectancy at birth of 12.69 years.
39%[3]
39% of US households own a cat, which is about 53 million households.
11.18 years[4]
US cats seen at Banfield hospitals have an average life expectancy at birth of 11.18 years.
We built the this numbers from American Pet Products Association (APPA) 2025 State of the Industry and Montoya et al. 2023, Frontiers in Veterinary Science, and both are worth a look if you want the detail.
The local attitude to ashes and memorials
Cremation accounts for roughly 74.7%[5] of human deaths in Maine, and a lot of those ashes end up waiting on a shelf. That's true of pets as well. If you already have an urn at home from an earlier pet, a bio urn can be a way to finish that story: the older ashes and the new can go into one planting, or two trees side by side, whenever you feel ready.
Direct Cremate (citing CANA) (2024) is where the Maine figure comes from. It counts people; we use it because attitudes to cremating a pet in Portland tend to follow attitudes to cremation generally.
What Portland's climate means for a living memorial
In Portland, average lows fall below freezing in January, February, March, November and December, and frozen ground makes digging hard or impossible. That's no reason to rush. Ashes keep safely indoors for as long as you like, so many families wait for spring, once the soil has thawed and drained. Early autumn works too, as long as the tree has about six weeks of open ground to root in before the hard frosts.
Freezing and thawing through January, February, March, November and December can heave a newly planted tree out of the ground in Portland. If you plant in autumn, mulch well after the first frost to keep the soil temperature steady, and check the base of the tree in spring. A spring planting avoids the problem entirely and gives roots a full growing season before the next winter.
What a greener goodbye costs in Portland
Add up every part before you commit. Beyond the cremation, a living memorial in Portland can include the bio urn, compost and bark, a pH kit, the tree or shrub, a guard against deer or rabbits, and perhaps a marker. Our memorial budget planner lists each line so nothing surprises you. Most families find the tree is the cheapest part and the cremation the most expensive.
Rather than repeat the price table on every city page, we keep one for Maine: Maine costs. What each service includes is on the services page.

Where you can plant or release ashes in Maine
Rules about ashes were mostly written for people, and pet ashes often sit in a grey area. That's a reason to ask, not a reason to assume. On land you own, planting or burying ashes is generally fine. Anywhere else in Maine, from parks to beaches to a friend's field, the land manager or owner decides, so ask first.
Maine keeps an official directory of local governments; use it to reach the county or city office that covers Portland.
The rules that apply across Maine (home burial, scattering and who oversees pet cremation) are summarized on our Maine page. Portland may add its own conditions, so check with the city or county before digging.
From ashes to a growing tree: the steps
- If the ashes have been on a shelf for years, planting is still an option. Ashes don't degrade with age, so nothing has been missed.
- Open the container carefully somewhere sheltered from wind, and check whether the ashes are in a sealed bag inside.
- Weigh or measure what you have, and put the figure into our urn size calculator to find a planting or water urn of the right capacity.
- Decide whether to keep any back. After years at home, some families like to plant most of the ashes and keep a spoonful.
- Pick a date that carries meaning, perhaps the day they died or the day they were born, and ask the people who loved them to come.
- Treat the old urn kindly afterwards. Many people reuse a wooden or ceramic urn as a plant pot or keepsake box.
Ways to mark the spot and the date
In Portland's apartments and older houses, space is often tight, so many families pick a compact urn, a tin of keepsakes or an ash-filled charm rather than a large memorial. A window ledge overlooking the bay or a bookcase in the front room can make a meaningful spot. If you rent, anything portable beats a garden stone you would have to leave behind.

Questions people ask
How many pet owners live in Portland?
By our estimate, about 25,500 households in Portland have at least one dog or cat, and around 2,150 are lost each year. We calculate this from the city's population of about 69,911, the average household size and national ownership and lifespan figures, so treat it as a floor rather than an exact count.
Why does the Portland page quote a human cremation rate?
Because it is the best local signal we have. Direct Cremate (citing CANA) (2024) reports about 74.7%[5] of Maine residents are cremated. There is no official pet equivalent, and inventing one would be worse than quoting a real, clearly labelled number.
How does Portland's weather affect pet aftercare?
July is the hottest month in Portland, with average highs around 80°F, so prompt collection matters most then. Average lows drop below freezing in January, February, March, November and December, which can make digging a grave hard until spring.
Which nearby towns can I compare with Portland?
The closest communities we cover are South Portland (about 2 miles), Westbrook (about 6 miles) and Saco (about 12 miles). Providers based in those places often serve Portland too. Ask each one for a written total that includes collection, so the distance is priced in.
Do bio urns work with ashes from flame cremation?
Yes. A bio urn works with ashes from flame cremation or water cremation. Both leave mineral-rich, alkaline ash, so the soil advice is the same either way: dilute the ashes well through compost and soil, let the mix rest if you can, and test the pH before a young tree goes in.
Can I take my pet's ashes on a plane to plant them somewhere else?
Usually, yes. Most airlines let you carry cremated remains in hand luggage, but security staff need to be able to X-ray the container, so a wooden, plastic or cardboard container is easier than a metal urn. Keep the certificate from the crematory with you. Leave any seed pod at home if you're crossing a border that restricts plant material.
