Question 1

Should I dethatch in spring or fall in NB?

Accepted Answer

Spring is the better time for dethatching in New Brunswick, specifically late April to early May when the ground has firmed up but before the grass enters its peak growing season. This timing allows your lawn to recover and fill in bare spots during the prime growing months of late spring and summer.

Dethatching timing is critical in NB's climate because our lawns face a challenging combination of high Maritime humidity, snow mold pressure, and a relatively short growing season. When you dethat

Question 2

Best order for spring garden cleanup tasks?

Accepted Answer

Start with debris removal and soil assessment, then move to pruning and preparation tasks as conditions improve. The key in New Brunswick is waiting for the right soil conditions and timing each task to our Maritime climate.

Begin with debris and damage assessment as soon as you can walk on your lawn without leaving deep footprints, typically mid to late April. Remove winter debris like fallen branches, leftover leaves, and any protective coverings from plants. Check for winter damage on trees

Question 3

When should I refresh mulch in garden beds?

Accepted Answer

In New Brunswick, refresh mulch in garden beds every 1-2 years, with the best timing being late spring (mid to late May) after the soil has warmed but before summer heat arrives.

The timing depends on your mulch type and garden conditions. Organic mulches like shredded bark, wood chips, or compost break down faster in our Maritime climate due to high humidity and moisture, typically needing refreshing annually. Stone mulches or rubber mulch can last 2-3 years but may need topping up where they'

Question 4

Is it better to plant grass seed in spring or fall in New Brunswick?

Accepted Answer

Fall is overwhelmingly the better time to plant grass seed in New Brunswick — specifically mid-August through early September — delivering germination rates and establishment success that spring seeding simply cannot match. The combination of warm soil, cooling air temperatures, reduced weed competition, and reliable fall rainfall creates near-perfect conditions for grass seed establishment in NB's Maritime climate.

The science behind fall's superiority is straightforward. By mid-August, NB soi

Question 5

How do I prepare a new garden bed in fall for spring planting in NB?

Accepted Answer

Preparing a new garden bed in fall is the smartest approach in New Brunswick because NB's freeze-thaw cycles over winter naturally break up heavy soil, and organic amendments have months to integrate before spring planting. Start this process in September or October while the ground is still workable, and by May you'll have a bed that's dramatically easier to plant into than anything you could prepare in spring.

Begin by marking out your bed shape and removing the existing turf. For small beds,

Question 6

When is the right time to stop mowing in fall in New Brunswick?

Accepted Answer

Stop mowing your New Brunswick lawn in October, with your final cut typically falling between October 10-25 depending on your location in the province and that year's weather pattern. The key indicator is when grass growth slows to the point where it's no longer reaching your mowing height between weekly cuts — once the grass isn't growing, there's nothing to cut, and running a mower over dormant turf just compacts the soil.

Grass growth in NB slows dramatically once soil temperatures drop belo

Question 7

What is the spring pruning schedule for common NB shrubs and trees?

Accepted Answer

The spring pruning schedule for New Brunswick shrubs and trees follows one fundamental rule: prune spring-flowering plants AFTER they bloom, and prune summer-flowering plants BEFORE they leaf out in early spring. Getting this wrong — particularly pruning spring bloomers in early spring — is the most common pruning mistake NB gardeners make, and it eliminates that year's entire flower display because spring-flowering plants set their buds the previous fall.

March is the time for dormant pruning

Question 8

How do I transition my garden from summer to fall in New Brunswick?

Accepted Answer

Transitioning your garden from summer to fall in New Brunswick is a gradual process that begins in late August and continues through October, involving strategic cleanup, planting fall interest, and beginning winter preparation while the growing season still has weeks of warmth remaining. Rather than a sudden transformation, think of it as a phased handoff where you're simultaneously winding down summer performers and setting up for fall beauty and winter readiness.

In late August, start by rem

Question 9

When should I do my final fall leaf cleanup to protect my NB lawn?

Accepted Answer

Your final fall leaf cleanup in New Brunswick should be completed by late October to early November, before the first lasting snowfall buries the leaves and traps them against your lawn for the entire winter. Leaves left on the lawn through winter create a wet, matted layer that blocks sunlight and air circulation, creating ideal conditions for snow mold — one of the most common lawn diseases in NB's Maritime climate.

The timing depends partly on where you live in the province. Coastal areas ar

Question 10

How do I winterize my sprinkler system before NB's first freeze?

Accepted Answer

You should winterize your sprinkler system in New Brunswick by late October at the latest, using compressed air to blow out all remaining water from the lines, valves, and heads before the ground freezes to frost depth. NB's frost depth reaches 1.2-1.5 metres, which means any water left in buried irrigation lines will freeze, expand, and crack pipes, fittings, and valve bodies. Repair costs from freeze damage typically run $300-1,000 or more, making the $75-150 cost of professional winterization

Question 11

How do I protect rose bushes through New Brunswick's harsh winters?

Accepted Answer

The key to overwintering roses in New Brunswick is a combination of proper timing, mounding, and insulation, applied after the first hard frost in late October but before the ground freezes solid. Roses are one of the most vulnerable garden plants in NB's Zone 4-5 climate, but with the right preparation, even hybrid teas can survive winters that regularly hit -25°C to -30°C.

Start by stopping deadheading and fertilizing by mid-August. This signals the plant to begin hardening off for winter rat

Question 12

When should I remove winter wraps and protection from plants in NB spring?

Accepted Answer

Begin removing winter wraps and protection from plants in New Brunswick in mid-April, when daytime temperatures consistently reach 5-10°C and nighttime lows stay above -5°C for a sustained period. The key word is gradually — removing everything at once on the first warm day risks shocking plants with sudden sun exposure and late spring frosts that are common in NB well into May.

Start with burlap windscreens and trunk wraps on deciduous trees around mid-April. These are the least critical prote

Question 13

What is the ideal summer lawn care schedule for the Moncton area?

Accepted Answer

The ideal summer lawn care schedule for the Moncton area follows a weekly rhythm of mowing, targeted watering, and pest monitoring from June through August, taking advantage of Moncton's Zone 5a-5b climate and relatively longer growing season compared to inland NB. Summer is when your lawn faces its biggest stresses — heat, drought periods, insect pressure, and heavy use — so consistency matters more than any single treatment.

Mowing is your most important summer task. Set your mower height to

Question 14

What should be on my fall garden winterization checklist for NB?

Accepted Answer

Your fall garden winterization checklist for New Brunswick should begin in mid-September and wrap up by late October, covering everything from soil amendments to physical plant protection before the ground freezes. NB's winters are long and harsh — with 250-300 cm of snow and temperatures dropping to -25°C or colder — so thorough fall prep makes the difference between a garden that bounces back in spring and one that suffers significant losses.

Start in September with a fall fertilizer applicat

Question 15

How do I prepare perennial gardens for a New Brunswick winter?

Accepted Answer

Preparing perennial gardens for a New Brunswick winter is all about timing your cutbacks, applying the right mulch depth, and protecting marginally hardy specimens — ideally between mid-October and mid-November, after a few hard frosts but before the ground freezes solid. NB's Zone 4a-5b climate means most well-chosen perennials will survive winter without heroic measures, but proper preparation reduces spring dieback and speeds up recovery.

Begin by assessing each plant's needs individually. C

Question 16

When should I wrap shrubs and trees for winter protection in NB?

Accepted Answer

The ideal window for wrapping shrubs and trees in New Brunswick is late October through mid-November, after the plants have gone fully dormant but before heavy snowfall and sustained freezing temperatures arrive. Wrapping too early traps heat and moisture, encouraging fungal growth, while waiting too long means working with frozen materials and risking damage from early winter storms.

Not every shrub or tree needs wrapping — focus your efforts on the most vulnerable specimens. Broadleaf evergre

Question 17

When is the best time to apply fall fertilizer to my NB lawn?

Accepted Answer

The best time to apply fall fertilizer to your New Brunswick lawn is September — specifically the first two to three weeks of the month — while the grass is still actively growing but daytime temperatures have moderated from summer highs. This timing gives the fertilizer 4-6 weeks of active uptake before the grass goes dormant in late October, building the root reserves and cold hardiness your lawn needs to survive NB's harsh winters.

Choose a fertilizer with a high potassium ratio for fall app

Question 18

When should I start spring cleanup after snowmelt in New Brunswick?

Accepted Answer

The ideal time to start spring cleanup in New Brunswick is mid-April in coastal areas like Moncton and Saint John, and late April to early May in inland and northern regions like Fredericton, Woodstock, and Bathurst. The critical factor is not when the snow disappears but when the ground has firmed up enough to support foot traffic and equipment without causing compaction damage.

New Brunswick's spring is notoriously slow and uneven. Coastal Zone 5a-5b areas often see snow disappear by early Ap

Question 19

What is the complete spring lawn care checklist for New Brunswick homeowners?

Accepted Answer

A complete spring lawn care checklist for New Brunswick starts with patience — wait until the ground firms up in mid-April before doing any work, as walking on soggy turf compacts the soil and damages grass crowns. NB's freeze-thaw cycle through March and early April means lawns need time to stabilize before you begin cleanup and treatment.

Step one is a thorough spring rake to remove dead grass, matted leaves, and any snow mold that developed over winter. Snow mold is extremely common in New B
