About Totara

Podocarpus totara · also called totara, New Zealand totara · flowering

A long-lived New Zealand conifer with stiff, sharp-pointed bronze-green needles and distinctive stringy reddish bark. Slow-growing but eventually a substantial tree, it tolerates wind, coastal exposure, and poor soils. Female trees bear fleshy red receptacles holding the seed. Grown as a specimen, shelterbelt, or clipped hedge in mild climates.

Growth habit: Upright evergreen conifer, conical when young and broadening with age into a tall tree; tolerant of hard pruning and shearing for hedging.

Watch for — Wind burn when young: Newly planted trees can scorch in harsh, exposed wind before establishing; provide temporary shelter in the first year.

What fertiliser totara actually wants — and why

Totara 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 totara: 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 totara, 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 totara:

Low-maintenance feeder. Apply a balanced slow-release fertiliser once in spring during the establishment years; mature trees rarely need feeding. 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 totara 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 totara

Half strength is the safe default for totara — 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 totara first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the totara watering schedule.

Signs you are over-feeding totara

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

Flushing and leaching the salts

Flush the pot of totara 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 totara

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.

What strength of feed for totara?

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

What does over-feeding totara 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 totara 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 totara?

Flush the pot of totara 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.
