Sequoia sempervirens, commonly known as the Coast redwood, is a conifer native to the United States. Its range extends across California.

This tree is generally found at low to medium altitudes, mostly from 100 m (328 ft) to 2,500 m (8,200 ft).

The coast redwood is a super giant among trees, reaching a height of 115 m (379 ft). The trunk diameter can exceed 9 m. The bark is soft and very thick (20 cm) with a grey - brown colour. The needles are 2 cm long and have a medium green colour. The cones are spherical and 3 cm diameter. The dark brown cones take 8 months to ripen.

It can live up to 3,000 years.

The Coast redwood is closely related to the Giant Redwood, which shares many of its characteristics.

This species produces highly valuable timber with a high rot resistance. This is the ultimate tree for large gardens if size matters to you. It is the tallest living thing on the planet. It can be used for bonsai also.

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 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.
