This tree is generally found at medium altitudes, mostly from 1,400 m (4,590 ft) to 2,000 m (6,560 ft).

The Giant Redwood is a very large evergreen conifer, reaching a height of 95 m (311 ft). The trunk diameter has been recorded over 8 m. The bark is orange - brown and rough. This tree is the largest living organism by mass on earth. The needles are light green. The cones are 8 cm long and hold up to 200 seeds. Cone colour is light brown.

Pre Germination

These seeds need no pretreatment or stratification before sowing. Fill trays or pots with quality compost and firm down gently. Spread seeds across the surface; around 25 in a 10 cm pot is ideal. Cover with 3 mm of compost and gently firm down.

Keep compost damp, not soaking wet or dried out. Place pots or trays on a warm windowsill or in a warm conservatory. Germination should occur at 1–3 weeks.

Post Germination

Keep seedlings appear in a bright, well-ventilated area to avoid damping off disease. Ensure seedlings never dry out or become waterlogged. These seedlings are large and sturdy and will give you little hassle. They can be separated into 4" pots at 15–20 weeks; by this stage they are frost hardy and can stay outside. Fertilization is not required up to this point. During spring and summer we advise using an NPK 10-10-10 fertilizer every 4 weeks.

CAUTION: Slugs and snails love juicy young pines and spruce.
