Question 1

Yellow spots near sprinkler heads on my lawn?

Accepted Answer

Yellow spots around sprinkler heads are typically caused by overwatering, fertilizer burn from concentrated nutrients, or dog urine damage. The most common culprit in New Brunswick is overwatering combined with our clay-heavy soils that don't drain well.

Overwatering is the primary cause, especially in areas like Fredericton and the Saint John River valley where clay soils are common. When sprinkler heads deliver too much water or run too frequently, the soil becomes waterlogged and oxygen-star

Question 2

Common tree pests in NB and how to spot them?

Accepted Answer

New Brunswick's trees face several common pests that can cause significant damage if not caught early. The Maritime climate's high humidity and temperature fluctuations create ideal conditions for many insects and diseases, making regular monitoring essential for tree health.

Spruce budworm is arguably the most destructive pest in New Brunswick, particularly affecting balsam fir and white spruce. Look for reddish-brown caterpillars feeding on new growth in late spring, causing needles to turn b

Question 3

Why is my paver patio sinking or heaving after a NB winter?

Accepted Answer

Paver patios that sink, heave, or become uneven after a New Brunswick winter are almost always the result of an insufficient gravel base that fails to prevent frost heaving — NB's deep frost penetration (4-6 feet in inland areas) demands a more robust base than many contractors and DIY installers provide. The freeze-thaw cycles typical of Maritime winters, where temperatures can swing from -20°C to +5°C within days, create enormous upward pressure as soil moisture freezes and expands beneath an

Question 4

How do I get rid of ant hills in my New Brunswick lawn?

Accepted Answer

Ant hills in New Brunswick lawns are primarily built by common pavement ants and field ants, and while they are a nuisance that creates unsightly mounds and uneven surfaces, the ants themselves are actually beneficial insects that aerate soil and control other pest populations. The sandy, well-drained soils common in coastal NB areas near Moncton and Saint John are particularly attractive to ant colonies, though hills can appear in any NB lawn.

Question 5

How do I deal with Japanese beetles in New Brunswick gardens?

Accepted Answer

Japanese beetles have become an increasingly serious pest in southern New Brunswick, particularly in the Moncton, Saint John, and Fredericton regions, where they voraciously feed on roses, linden trees, grapes, raspberry bushes, and dozens of other ornamental and edible plants. These metallic green-and-copper beetles are about 1 cm long and feed in groups, skeletonizing leaves by eating the tissue between veins, leaving behind a lace-like pattern that is unmistakable.

Adult Japanese beetles are

Question 6

What causes tree bark to split during New Brunswick winters?

Accepted Answer

Tree bark splitting during New Brunswick winters is primarily caused by frost cracking — a phenomenon where rapid temperature fluctuations cause the bark and outer wood to expand and contract at different rates, creating vertical splits that can run several feet along the trunk. This is especially common on the southwest-facing side of trees, where winter sun warms the bark during the day to well above freezing, then temperatures plummet rapidly after sunset — a cycle that NB's continental-influ

Question 7

How do I fix lawn damage caused by dog urine in New Brunswick?

Accepted Answer

Dog urine damages New Brunswick lawns because it contains high concentrations of nitrogen salts — essentially a massive overdose of fertilizer in a small area — that burns and kills the grass, leaving characteristic circular brown spots often surrounded by a ring of darker green, lush grass. The green ring results from the diluted nitrogen at the edges actually fertilizing the grass, while the concentrated centre dose kills it. Female dogs and large breeds cause the worst damage because they voi

Question 8

Why are mushrooms growing in my New Brunswick lawn?

Accepted Answer

Mushrooms appearing in your New Brunswick lawn are actually a sign of healthy soil biology — they are the fruiting bodies of beneficial fungi that are actively decomposing buried organic matter such as old tree roots, construction lumber, or buried stumps. While they may look alarming, the vast majority of lawn mushrooms in NB are harmless to your grass and are actually improving your soil by breaking down woody debris into nutrients your lawn can use.

New Brunswick's Maritime climate creates i

Question 9

How do I fix a patchy lawn after a construction or paving project in NB?

Accepted Answer

Restoring a lawn after construction or paving in New Brunswick requires addressing the severe soil compaction, debris contamination, and disrupted grade that heavy equipment inevitably leaves behind. Simply scattering seed over the damaged area rarely works because the underlying soil conditions are hostile to grass establishment — this is one of the most common mistakes NB homeowners make after a driveway, addition, or septic installation project.

Start by assessing the damage thoroughly. Walk

Question 10

Why are my hostas not thriving in my New Brunswick shade garden?

Accepted Answer

Hostas that fail to thrive in New Brunswick shade gardens are most commonly suffering from slug damage, poor soil conditions, or too much shade — even for these famously shade-tolerant plants. While hostas are considered one of the most reliable perennials for NB gardens (hardy to Zone 3), they do have specific requirements that Maritime conditions can complicate.

Slugs are the number one hosta enemy in New Brunswick, and the province's damp Maritime climate creates paradise conditions for thes

Question 11

What causes white fungus patches on my NB lawn every spring?

Accepted Answer

Those white or greyish-pink fuzzy patches appearing on your New Brunswick lawn in early spring are almost certainly snow mold, a fungal disease that develops under snow cover during the long Maritime winter. NB is particularly susceptible because of the combination of prolonged snow cover, fluctuating freeze-thaw cycles, and high humidity — conditions that create an ideal breeding ground for these fungi.

There are two common types in New Brunswick. Grey snow mold (Typhula spp.) produces circula

Question 12

How do I fix severely compacted soil under a New Brunswick lawn?

Accepted Answer

Severely compacted soil is one of the most common lawn problems in New Brunswick, especially in newer developments around Moncton, Fredericton, and Saint John where heavy construction equipment has compressed the subsoil into a nearly impenetrable layer. Compacted soil prevents water infiltration, restricts root growth, and reduces oxygen availability — resulting in thin, stressed turf that struggles through NB's hot summers and cold winters alike.

The most effective immediate remedy is core ae

Question 13

Why are my cedar hedges turning brown in New Brunswick?

Accepted Answer

Cedar hedges turning brown in New Brunswick is extremely common and usually results from winter desiccation — a condition where cold, dry winter winds draw moisture from the foliage faster than frozen roots can replace it. This is the number one cause of cedar browning across the province, particularly on the south and southwest-facing sides of hedges that receive the most wind and winter sun exposure. The damage typically appears in late February through April as brown, dry patches on the outer

Question 14

How do I treat powdery mildew on plants in NB's humid climate?

Accepted Answer

Powdery mildew appears as a white or grey powdery coating on leaves and stems, and it thrives in New Brunswick's humid Maritime climate, particularly during the warm, humid days and cool nights typical of July through September. While rarely fatal to established plants, powdery mildew weakens growth, reduces flowering, and makes your garden look unsightly. Common NB targets include lilacs, bee balm, phlox, roses, cucumbers, squash, and zucchini.

Unlike most fungal diseases, powdery mildew actua

Question 15

How do I identify and treat grub damage in a New Brunswick lawn?

Accepted Answer

Grub damage in New Brunswick lawns typically appears as irregularly-shaped brown patches that feel spongy underfoot and can be peeled back like a carpet, revealing white C-shaped larvae feeding on grass roots just below the surface. The most common culprits in NB are European chafer grubs and June beetle larvae, which are most active from late August through October and again briefly in spring before pupating.

To confirm grub damage, cut a 1-square-foot section of affected turf about 3 inches d

Question 16

Why is my newly laid sod turning brown in New Brunswick?

Accepted Answer

Newly laid sod turning brown in New Brunswick is most often caused by insufficient watering during the critical root establishment period, though poor soil contact, heat stress, and improper installation timing can also be factors. Sod is essentially a living plant with its root system severed, and it needs consistent moisture to survive while new roots grow into your existing soil — a process that takes 2-4 weeks in NB's climate.

The most common mistake is underwatering during the first 14 day
