About Hall Totara

Podocarpus hallii · also called Mountain Totara, Hall's Totara · flowering

Hall Totara is a slow-growing New Zealand conifer found in subalpine and montane forests, featuring attractive peeling bark, narrow bronze-green leaves, and small red-fleshed seed cones. Hardy and architectural in cooler gardens. Podocarpus fruits and foliage are toxic to pets and children if ingested.

Mature size: Up to 20 m in the wild; typically 4-8 m in cultivation after many years

Watch for — Root rot: Caused by waterlogged soil; ensure excellent drainage especially on clay soils.

How to tell hall totara needs repotting

Repotting on a calendar is less reliable than reading the plant. For hall totara, watch for these signs:

Roots spiralling thickly out of the drainage holes or pushing the whole plant up out of the pot.
The pot is so packed that water runs straight through in seconds and barely wets the soil.
It has split a plastic pot, or the rootball is a solid mass with almost no soil left when you slide it out.
Growth and (for hall totara) flowering have clearly stalled despite good light and feeding — but remember this plant likes being snug, so a little crowding alone is not a reason to 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 hall totara

Only every 2–4 years, when genuinely crowded. Hall Totara is one of the plants that genuinely prefers a snug pot — it grows and flowers better with its roots a little restricted, so resist the urge to repot it on schedule. Upright evergreen conifer with peeling bark.

What size pot to step hall totara up to

Go up only one pot size — roughly 2–3 cm (about an inch) wider in diameter, no more. Hall Totara positively prefers a snug pot: it flowers and grows better when the roots are a little restricted. The single biggest repotting mistake here is over-potting — dropping hall totara into a pot two or three sizes up. All that surplus soil holds water the small root system cannot use, stays cold and wet, and rots the roots within weeks. When in doubt, choose the smaller pot.

Not sure of the exact diameter? Our pot size calculator takes the current pot and root spread and tells you the right next size — it deliberately recommends a single step up, never a big jump.

The best time of year to repot hall totara

Early spring, just as new growth restarts, is the ideal window for hall totara. 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 hall totara

Confirm it actually needs it. Slide hall totara out and check the roots. Only continue if it is genuinely packed — this plant prefers a snug pot, so if there is still soil and room, put it straight back.
Pick a pot only one size up. Choose a pot just 2–3 cm wider with good drainage. Resist anything bigger; over-potting is the main killer here.
Ease it out gently. Water lightly the day before, then tip hall totara out, supporting the base. Tease the outer roots free only enough to stop them circling.
Repot at the same depth. Add a layer of fresh moist, well-drained loam or sandy loam, set the plant so the soil line sits exactly where it did before, and backfill around the sides, firming lightly.
Settle it in. Water once to settle the soil, then let it sit. Hold off on more water until the top of the soil dries — fresh soil around a small root system stays wet for a while.

Aftercare

Because the new soil holds more water than the old crammed rootball did, ease right back on watering — let the top of the soil dry before you water hall totara again, or you will rot the roots in the very pot you just moved it to. Keep it out of harsh direct sun for a fortnight. Do not fertilise for about 4 weeks — fresh mix already carries nutrients and feeding freshly disturbed roots scorches them.

The right soil mix for hall totara

Hall Totara wants moist, well-drained loam or sandy loam. Tolerates a range of soil types including slightly acidic to neutral (pH 5.5–7.0). Good drainage is essential; amend compacted soils with organic matter and coarse grit. Mulch around the base to retain moisture. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting hall totara — frequently asked questions

How often should you repot hall totara?

Only every 2–4 years, when genuinely crowded for hall totara. Only repot hall totara every 2–4 years, and only when it is genuinely root-bound — it flowers and grows best slightly crowded. Step up just one pot size in spring using moist, well-drained loam or sandy loam. The key mistake is over-potting: a too-big pot stays wet and rots the roots.

What size pot does hall totara need?

When is the best time of year to repot hall totara?

Does hall totara like to be root-bound?

Yes — hall totara genuinely flowers and grows best when slightly pot-bound, so do not rush to repot it. The mistake to avoid is over-potting into a much larger pot: the excess soil stays wet, the roots cannot use it, and the plant rots. Only repot every few years and only one snug size up.

Should you fertilise hall totara after repotting?

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