About Weeping Nootka Cypress

Cupressus nootkatensis 'Pendula' · also called Weeping Nootka Cypress, Weeping Alaska Cedar · flowering

A dramatic, narrowly columnar cultivar of Nootka Cypress with strongly weeping, pendulous branch tips that hang almost vertically. A slow-growing specimen tree prized in large gardens, parks, and streetscapes for its elegant, architectural silhouette year-round. Cold-hardy and adaptable, it tolerates wet soils and cool climates better than most ornamental conifers.

Mature size: 10–20 m tall, 2–4 m wide (slow-growing, decades to reach full height)

How to tell weeping nootka cypress needs repotting

Repotting on a calendar is less reliable than reading the plant. For weeping nootka cypress, watch for these signs:

Thick roots out of the drainage holes, or circling the surface and lifting the plant.
The pot dries out unusually fast and weeping nootka cypress wilts between waterings it used to shrug off.
The plant is visibly top-heavy and tips over easily.
Stalled growth and small new leaves over a full season — though with a big specimen, top-dressing is often the better first response before a full repot.

For the underlying biology of a pot-bound root system and why it stalls a plant, see our guide to spotting and fixing a root-bound plant.

How often to repot weeping nootka cypress

Every 2–3 years; top-dress in the in-between years. Weeping Nootka Cypress's growth habit — narrowly columnar to fastigiate evergreen tree with steeply pendulous branch tips giving a 'curtain' or weeping effect — sets the pace. A dramatic, narrowly columnar cultivar of Nootka Cypress with strongly weeping, pendulous branch tips that hang almost vertically. A slow-growing specimen tree prized in large gardens, parks, and streetscapes for its elegant, architectural silhouette year-round. Cold-hardy and adaptable, it tolerates wet soils and cool climates better than most ornamental conifers.

What size pot to step weeping nootka cypress up to

Move up exactly one pot size. A heavy weeping nootka cypress dropped into a vastly bigger pot sits in a reservoir of wet soil its roots cannot reach, which rots them and destabilises the plant. In the years between repots, lift off and replace the top 3–5 cm of soil (top-dressing) instead — it refreshes nutrients without the shock of a full repot.

The best time of year to repot weeping nootka cypress

Early spring, just as new growth restarts, is the ideal window for weeping nootka cypress. The plant is moving into its strongest growth phase and re-roots into fresh soil quickly. Avoid repotting in winter dormancy or, for flowering plants, while it is in bud or bloom — recovery is slowest then and you risk dropping the flowers.

Step-by-step: repotting weeping nootka cypress

Consider top-dressing first. If weeping nootka cypress is not badly root-bound, scrape off and replace the top 3–5 cm of soil instead — far less shock for a big plant that hates moving.
Get help and one size up. For a full repot, choose a pot just one size larger. A heavy plant needs two people and a stable, free-draining pot.
Ease it out on its side. Lay the plant down, slide the pot off, and gently loosen the outer roots. Do not bare-root a mature specimen.
Repot at the same depth. Add fresh moist, well-drained to moderately wet, acidic to neutral beneath and around the rootball, keeping the original soil line. Firm it so the trunk is stable and upright.
Water and leave it put. Water thoroughly, then leave weeping nootka cypress in the same spot and light — moving and repotting at once is what makes it drop leaves.

Aftercare

Leave weeping nootka cypress in exactly the same spot and light it was in before — moving and repotting at the same time is what makes a big specimen drop leaves. Water it in well, then let the top of the soil dry before watering again so the larger volume of fresh soil does not stay sodden. Do not fertilise for about 4 weeks — fresh mix already carries nutrients and feeding freshly disturbed roots scorches them.

The right soil mix for weeping nootka cypress

Weeping Nootka Cypress wants moist, well-drained to moderately wet, acidic to neutral. Adaptable to a wide range of soils including moist, poorly drained sites. Prefers acidic to neutral pH (5.0–7.0). Avoid hot, dry, alkaline soils. Tolerates heavier clay better than most conifers if not in standing water during summer. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting weeping nootka cypress — frequently asked questions

How often should you repot weeping nootka cypress?

Every 2–3 years; top-dress in the in-between years for weeping nootka cypress. Fully repot weeping nootka cypress only every 2–3 years; in the in-between years just top-dress the top 3–5 cm of soil. Step up one pot size in spring with moist, well-drained to moderately wet, acidic to neutral. It is heavy and hates being moved, and a vastly oversized pot holds water against the roots and rots them.

What size pot does weeping nootka cypress need?

When is the best time of year to repot weeping nootka cypress?

Should you top-dress or fully repot weeping nootka cypress?

For a big, heavy weeping nootka cypress, top-dressing — replacing the top 3–5 cm of soil — is the gentler option most years, with a full repot only every 2–3 years. A mature specimen sulks and drops leaves when fully repotted, so do it as rarely as the roots allow.

Should you fertilise weeping nootka cypress after repotting?

Not immediately. Wait about 4 weeks after repotting weeping nootka cypress. Fresh mix already contains nutrients, and feeding freshly cut or disturbed roots burns them. Resume your normal feeding routine once you see new growth.
