Troubleshooting
Rimu problems — and how to fix them
Rimu (Dacrydium cupressinum) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Slow growth
Naturally very slow-growing; patience is essential — ensure consistent moisture and organic mulch for best results.
Root rot in clay soils
Heavy, waterlogged soils cause root decline; improve drainage before planting.
Frost damage to young plants
Young specimens are more frost-sensitive; protect in the first winter in cold, exposed gardens.
Drought stress
Prolonged dry periods cause foliage browning; maintain consistent soil moisture with mulch.
