Troubleshooting
Dawn Redwood 'Ogon' problems — and how to fix them
Dawn Redwood 'Ogon' (Metasequoia glyptostroboides 'Ogon') 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.
Colour loss in shade
Insufficient sun fades the golden needles to green and weakens the upright form. Plant in full sun for best colour.
Tip scorch in heat
Bright new foliage can brown at the edges in hot, dry, exposed sites. Keep soil moist and give some afternoon shade where summers are intense.
Iron chlorosis on chalk
Alkaline soils cause interveinal yellowing of the needles; amend with organic matter or plant on more neutral-to-acidic ground.
Needle drop from drought
Because it loves moisture, drying out triggers premature needle browning and loss, especially in young trees; mulch and irrigate in dry weather.
