Instruc­tions for something big

Growing from seed indoors is possible all year round. To improve germi­nation, first store the seed in a plastic bag in the normal refrig­erator area for a week. Only then press it carefully into moist growing soil. As a light germi­nator, sequoia seeds only want to be covered very lightly with soil. Cover the propa­gator with cling film and make holes in it. This protects the soil from drying out. Every two to three days you should remove the foil for 2 hours. This prevents mould from forming on the soil. Keep the potting soil moist, but not wet. The first seedlings should appear after two to six weeks. 

Please bear in mind that the coast redwood will grow into a large tree after planting out. Therefore, you should allocate it an appro­priate place from the beginning. Ensure good soil drainage. As a shallow rooter, the tree does not tolerate long dry periods. However, due to its tolerance to flooding in the delta regions of the coasts, it has no problems with heavy soils that retain moisture for a long time. 

Please ensure that your redwood receives suffi­cient water during the dry summer months. This also applies to older specimens, as the tree does not root deeply. Young plants can also be immersed in a larger container once a week until the root ball is completely saturated with water. Fertil­i­sation is not usually necessary for redwoods. 

In winter:
Only when the lower part of the trunk has become woody to a height of 10 to 15 centimetres is there a certain winter hardiness for planting outdoors. Up to the age of three, the tree should therefore be kept in a container and watered lightly in winter. In the first winter after planting, you should also protect the root area somewhat, for example with a layer of brushwood. But even then the coast redwood is only winter­proof to a limited extent. It usually does not survive long periods of cold with temper­a­tures below ‑10° to ‑15° Celsius.
