About Pacific Dogwood

Cornus nuttallii · also called Pacific Dogwood, Mountain Dogwood · flowering

Pacific dogwood is the western counterpart to Cornus florida, native to forests of the US Pacific Coast and British Columbia. It bears large, showy white bracts — typically 4–6, sometimes 6–8 — in spring, often reblooming in autumn, with vivid orange-red autumn foliage. Stunning in its native range but notoriously difficult to establish outside Pacific Coast conditions.

Growth habit: Medium-sized deciduous tree with a pyramidal to oval crown when young, broadening with age. Branching is more upright than Cornus florida, giving a less distinctly tiered appearance but a more formal silhouette. Bark is attractively checkered on older trees.

What fertiliser pacific dogwood actually wants — and why

Pacific Dogwood is an easy, light foliage feeder — a half-strength balanced liquid feed through the growing months keeps it green without forcing weak, sappy growth.

A balanced general houseplant feed (roughly even N-P-K) is exactly right — it is grown for foliage, so steady, moderate nitrogen for healthy leaves is the goal, not a bloom or root formula.

For the language behind the three numbers on the bottle — what nitrogen, phosphorus and potassium each do — see the NPK ratio explained entry. The short version for pacific dogwood: match the feed to the job the plant is doing right now, not to a generic “plant food” on the shelf.

How often to feed pacific dogwood, and which months

Feeding only earns its keep while the plant is in active growth and can use the nutrients — pour feed into a dormant or low-light plant and it simply builds up as root-burning salt. For pacific dogwood:

Apply a slow-release balanced fertiliser in early spring during the establishment years. Mature trees in woodland gardens need only an annual mulch of leaf mould and compost to replace the forest duff layer they naturally grow in. Avoid heavy fertilisation, which pushes lush growth susceptible to crown canker. Treat that as sparingly through the growing season between spring through early autumn (roughly March to September); ease off in autumn and stop entirely in the low light of winter.

The dormant-season rule matters more than the exact interval: skip feeding entirely when pacific dogwood is resting. For the wider context on indoor feeding rhythms across the seasons, the houseplant fertiliser schedule walks through the year month by month.

What strength to mix for pacific dogwood

Half strength is the safe default for pacific dogwood — houseplant feeds are formulated strong, and the diluted dose is gentler on the roots while still ample for foliage.

Feeding always goes onto already-damp soil, never dry roots — water pacific dogwood first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the pacific dogwood watering schedule.

Signs you are over-feeding pacific dogwood

Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for pacific dogwood:

Flushing and leaching the salts

Flush the pot of pacific dogwood with plain water until it runs freely from the base every couple of months in the feeding season — it washes out the fertiliser salts that cause brown tips.

Organic vs synthetic feeds for pacific dogwood

Organic options

A diluted seaweed or worm-casting feed, or fish emulsion if you can tolerate the smell indoors. UK: Westland or Baby Bio Organic, dilute seaweed; US: Espoma Indoor! or Neptune's Harvest fish & seaweed. Slow, gentle and hard to overdo.

Synthetic / liquid feeds

A general-purpose houseplant liquid at half strength — UK: Baby Bio, Westland Houseplant Feed or Phostrogen; US: Miracle-Gro Indoor Plant Food or Schultz. Convenient and fast-acting; the only risk is overdoing it.

Brand names are examples, not endorsements, and UK and US ranges differ — check the label’s own NPK and dilution rate, since formulations change.

Half strength is the safe default for pacific dogwood — houseplant feeds are formulated strong, and the diluted dose is gentler on the roots while still ample for foliage.

What does over-feeding pacific dogwood look like?

Brown, crispy leaf tips and edges with no sign of underwatering. A white, crusty salt deposit on the soil surface or pot rim. Weak, pale, stretched new growth that flops. Lower leaves yellow and drop while the soil is correctly watered. Feeding pacific dogwood year-round on a fixed schedule, including dark winter months, is the most common mistake — it cannot use the nutrients in low light and the surplus simply burns the roots and crusts the soil.

Should I flush the soil of pacific dogwood?

Flush the pot of pacific dogwood with plain water until it runs freely from the base every couple of months in the feeding season — it washes out the fertiliser salts that cause brown tips.
