![]() ![]() More fun to do as a home gardener, is to collect the seeds yourself. For the Europeans amongst you, there are a number of good British or German nurseries that offer Sequoiadendron seeds (the tree is sometimes called Wellingtonia in British English and Mammutbaum in German). First you can buy them from nurseries/seed companies. To grow giant sequoias from seed, first thing you need to do of course is to get some seeds. After giving it a few unsuccessful tries myself, I finally got some seeds to germinate and am now the proud owner of some baby giant redwoods! Growing a giant redwood or a giant sequoia ( Sequoiadendron) from seed is not the easiest thing in the world, but it's certainly not impossible. More about growing the two other sequoia species: the coast redwood ( Sequoia sempervirens), and the dawn redwood ( Metasequoia glyptostroboides). You can grow giant sequoias by either sowing, striking cuttings or buying a little tree. Do you want to plant one anyway? Please go ahead and think about the next generations, that will hopefully be able to see this tree as a true giant. In one human life the giant sequoia is able to reach a girth of 4 to 5 m (13 to 16 ft). When you'll be, hopefully, an elderly person, your giant sequoia will only have grown through his first toddler years. A giant sequoia is not fit to plant as a small ornamental tree, but reaches its full potential as a landmark tree that can grown without restraints.īefore you enthusiastically imagining gigantic scenes: please keep in mind that, although the giant redwood is a vigorous grower according to plant terms, this species is living at another pace as you are. This might not come as a surprise but I have seen this tree planted very often in locations that were not well suited, as this species is a vigorous grower and can reach a height of 10 m (30 ft) after 10 years, and reaches a height of 30 m (100 ft) to 40 m (130 ft) after 50 years. More about the world regions where giant sequoias have been planted successfully, can be found here.īut you have to keep in mind that giant sequoia ( Sequoiadendron giganteum) are not fit for small city gardens. The answer is: yes you can, provided you're living in a temperate climate zone. Finally, we provide recommendations for P. forrestii conservation.Out of fascination for these big trees a lot of people are wondering: could I plant a giant redwood in my garden? Could I grow a giant sequoia from seed? Regeneration of P. forrestii depends on moderate natural disturbances. Established seedlings/saplings were mainly found in unstable micro-habitats. The growth of annual ring width of P. forrestii was slow, and generally decreased with age, whereas the basal area at the breast height increased with age. Its maximum age P. forrestii was 570 years with a DBH of 143 cm. DBH and age structures of P. forrestii showed multimodal distributions. The canopy layer was generally 10–25 m tall, with the emergent layer reached 25–42 m. ![]() The forest stratification was multilayered. Simpson diversity, Pielou evenness, Shannon–Wiener diversity indices ranged from 0.75 to 0.76, 0.74–0.81, and 1.62–1.93, respectively, with no significant differences among the four forest types. ![]() P. forrestii forests are characterized by both warm temperate and temperate affinities. We identified four P. forrestii community types: (1) Pseudotsuga forrestii - Quercus guyavifolia - A cer davidii evergreen coniferous and broad-leaved mixed forest (2) Pseudotsuga forrestii - P inus yunnanensis - Quercus guyavifolia evergreen coniferous and broad-leaved mixed forest (3) Pseudotsuga forrestii evergreen coniferous forest (4) Pseudotsuga forrestii - A bies georgei var. Here we clarify P. forrestii community types, structure, species diversity, seedling recruitments and growth trends. P. forrestii tree numbers have greatly decreased due to deforestation, over-utilization and habitat degradation. Pseudotsuga forrestii is a relict evergreen coniferous tree species in Pinaceae endemic to China. ![]()
