Garden maintenance is the ongoing care that keeps flower beds, shrub borders and vegetable plots healthy between planting projects: cleanup in spring, weeding, mulching, deadheading and dividing perennials through the season, and putting beds to rest in fall. Gardeners do it on a weekly or biweekly schedule or in a few seasonal visits, often alongside lawn care and hedge trimming.

In Canada the work follows a short, intense growing season. Beds wake up late, weeds race ahead in June, summer heat and watering rules test new plantings, and fall cleanup has to be done before the snow. It is also more regulated than many homeowners expect: provinces and municipalities limit which pesticides can be used in gardens, cities set watering hours, and some invasive plants, such as giant hogweed, are dangerous to handle.

This page follows the garden calendar, then covers core bed care, composting and yard waste, the pesticide and watering rules that apply to gardens, safe handling of invasive plants, and the choice between a regular gardener and seasonal visits.

Garden maintenance calendar: spring cleanup, summer care and fall cleanup

Spring cleanup starts once beds have thawed and dried enough to walk on without compacting the soil. Matted leaves, winter debris and last year's perennial stems come off, edges are recut, and beds are weeded, topped with compost and mulched before weeds get going. It's also the time to spot winter damage and salt injury along the street and driveway.

Summer is about staying ahead: weeding before weeds set seed, deadheading, staking tall perennials, watering new plantings during dry spells within local rules, and watching for pests and disease. Fall cleanup removes diseased foliage and spent annuals, protects tender plants and gets hoses and containers ready for winter.

Fall cleanup doesn't have to leave beds bare. Leaving some healthy perennial stems and seed heads standing over winter gives native bees and other pollinators hollow stems to shelter in and gives birds seeds to eat. Those stems can be cut back in spring once the weather warms.

Flower bed maintenance: mulching, weeding, deadheading and dividing perennials

Most of a gardener's time goes into a handful of recurring tasks. Done regularly, they keep beds looking tended with far less effort than a once-a-year rescue.

  • Mulching: shredded bark, wood chips or leaf mulch keeps soil moist, evens out its temperature and smothers weed seedlings, and is kept away from stems and plant crowns to avoid rot.
  • Weeding: pulling weeds while they are small and before they flower stops them from reseeding, and deep-rooted perennial weeds need the whole root out.
  • Deadheading: removing spent flowers keeps many annuals and perennials blooming longer and prevents self-seeding where it isn't wanted.
  • Dividing perennials: clumps that are crowded or dying out in the centre are lifted, split and replanted, usually in spring or early fall, which renews them and yields plants for other beds.
  • Edging: a clean edge between lawn and bed keeps grass from creeping in and makes the whole garden look cared for.

Composting garden waste and municipal yard waste collection

A garden produces a steady stream of trimmings, spent plants and leaves, and much of it can be composted on site. A mix of green material, such as fresh clippings, and brown material, such as dry leaves, breaks down into compost that goes back on the beds, and shredded leaves make a free mulch.

What can't be composted at home goes to municipal yard waste collection, which most cities run on set dates with rules on containers and bundles; Montreal, for one, doesn't accept plastic bags. Keep diseased plants, weeds that have gone to seed and invasive species out of the home compost, since a backyard pile rarely gets hot enough to destroy them.

Garden pesticide and watering rules in Ontario, Quebec and Montreal

Pesticide rules cover flower beds and vegetable gardens as well as lawns. Ontario's cosmetic pesticides ban limits gardens to products whose active ingredients all appear on the province's Allowable List, with health and safety exceptions such as poison ivy and giant hogweed. In Quebec, the Pesticides Management Code bars the highest-risk pesticides from lawns, trees, shrubs, vegetable gardens and flowerbeds, and municipalities such as Montreal add their own bans. Ask any gardener which products they plan to use, and expect hand weeding, mulch and low-risk options first.

Watering is regulated too. In Montreal, automatic systems may run only from 3 to 6 a.m. and portable sprinklers from 8 to 11 p.m., on even or odd days matching the address, and many other cities publish summer schedules they can tighten during a heat wave or shortage. Watering deeply at the base of plants, early in the day, and keeping beds mulched let a garden get by with less.

Invasive plants in the garden: giant hogweed and safe removal

Some garden escapes are more than a nuisance. Giant hogweed, a very tall perennial with broad umbrella-shaped clusters of white flowers, has sap that causes severe burns when skin that has touched it is exposed to light. Ontario warns that painful blisters appear within 48 hours, and Quebec notes that the sap's toxins are activated by sunlight and by artificial UV light. If sap gets on your skin, wash it well with soap and water and keep the area out of the sun; if it gets in an eye, rinse it immediately and see a doctor.

Never cut or pull giant hogweed bare-armed. Provincial guidance calls for waterproof gloves, long sleeves, long pants and eye protection, and Ontario recommends hiring a professional. No part of the plant should be composted, and Ontario says not to burn it; both provinces describe bagging cut plants and leaving the bags in the sun before disposal. In Quebec, its sale and cultivation are prohibited as of June 4, 2026 under the new regulation on invasive exotic plant species, which also covers buckthorn, as the hedge trimming page explains.

Hiring a regular gardener vs seasonal garden cleanups

A regular gardener visits every week or two through the growing season, which keeps weeds from getting ahead, catches pests and disease early and lets one person learn your garden. It suits large or densely planted yards, owners who travel in summer, and gardens that need to look good all season.

Seasonal visits, typically a spring cleanup, a summer tune-up or two and a fall cleanup, suit smaller or low-maintenance gardens and owners who enjoy the day-to-day care themselves. Many homeowners start with seasonal visits and add regular care once they see how fast weeds return in June.

  • Ask which tasks each visit includes: weeding, deadheading, edging, mulch top-ups, watering or cleanup.
  • Confirm whether debris removal, mulch and compost are part of the service.
  • Look for plant knowledge: a gardener who can tell a perennial seedling from a weed saves plants.

Garden Maintenance: frequently asked questions

Should I cut back perennials in the fall or in spring?

Both have a place. In fall, remove diseased foliage and plants that collapse after frost, but leave some healthy stems and seed heads standing for pollinators and birds. Cut those back in spring once new growth starts.

How much mulch do garden beds need?

Enough to block light from weed seeds and slow evaporation, topped up as it breaks down. Keep it away from stems, crowns and tree trunks, where it holds moisture against bark and invites rot. Gardeners usually refresh mulch in spring after weeding.

Can a gardener spray weeds in my flower beds?

Only with products allowed where you live. In Ontario, gardens can only be treated with pesticides whose active ingredients are all on the Allowable List, apart from health and safety exceptions. Quebec bars the highest-risk pesticides from flowerbeds and vegetable gardens, and municipalities such as Montreal add their own bans. Most garden weed control is done by hand, with mulch and dense planting.

How do I get rid of giant hogweed safely?

Don't touch it with bare skin. Wear waterproof gloves, long sleeves, long pants and eye protection, or hire a professional, as Ontario recommends. Don't compost or burn it; provincial guidance describes bagging cut plants and flower heads and leaving the bags in the sun before disposal.

How often should a gardener come?

It depends on the garden and how much you do yourself. Every week or two keeps a large, densely planted garden under control, while a smaller or low-maintenance garden may need only a spring cleanup, a summer visit or two and a fall cleanup.

What affects the cost of garden maintenance

Prices depend on the details of your project. We only publish price ranges when they’re backed by real LokalMatch quote data or reliable sources. Until then, here’s what usually changes the price:

  • Size of the yard and the scope of the design
  • Grading, excavation and drainage work
  • Hardscape materials, such as stone, pavers or wood
  • Plants, sod and soil
  • Access for machinery
  • Removal of old materials, trees or stumps
  • How often visits are scheduled for ongoing services

How to compare gardeners before you hire

  • Choose a company that does the kind of work you need, since design, lawn care, tree work and hardscaping are different specialties.
  • For big projects, ask for a site plan or drawing before work starts.
  • Ask how they'll handle grading and drainage so water moves away from the house.
  • For tree removal or large pruning, look for a qualified arborist with liability insurance.
  • For ongoing services like lawn care or snow removal, get the visit schedule and what's included in writing.

Questions to ask gardeners before you hire

  • Can I see a plan or drawing before you start?
  • How will you handle drainage and grading?
  • Will you have underground utilities located before you dig?
  • Does any of this work need a permit, such as for a retaining wall, fence or tree removal?
  • What plants or materials do you recommend for our climate and my yard's sun and shade?
  • Do you guarantee plants or sod, and for what conditions?
  • Can you show me proof of liability insurance?

When to call a pro for garden maintenance

  • Water that pools near the house or in the yard after rain
  • A tree that is leaning, cracked or has large dead branches over the house or a driveway
  • A retaining wall that is bulging, leaning or cracking

Garden maintenance permits and local rules

Some garden maintenance work needs a permit or has to meet local bylaws. Rules vary by municipality, so ask your pro whether a permit is needed and who will apply for it — and check with your city or town if you’re unsure.
