Living for up to 3000 years, Sequoiadendron giganteum are truly magnificant evergreen trees. The awl-shaped foliage provides year-round appeal along with the thick, spongy reddish brown bark. Cones are 4–7 cm long and decorate the tree in November, creating additional seasonal interest.
A conical form of 12 x 4 metres is reached in 20 years when planted in moist, well-drained soil, with a position in full or partial sun. Once established, this tree will tolerate some damp and inland exposure. Also commonly known as a Giant Redwood or Wellingtonia tree, this marvellous conifer will create a stunning feature in any good sized garden.

Planting Advice for Sequoiadendron Giganteum trees
When planting Wellingtonia trees, it is important to prepare the planting area well. Pot grown trees can be planted at any time of the year.
Firstly, remove all weeds and grass within a metre of your desired planting hole then dig a hole as deep as your root mass and approximately 2x as wide. We recommend digging a square hole as this encourages the roots to grow straight as opposed to around inside the hole. To help your tree establish more effectively, we advise applying root grow (sprinkle in the hole for pot grown trees), especially if you have poor soil. Gently loosen the roots and place into the planting hole.
If your soil is poor, mix 50% of the original soil with 50% high quality compost, fill in the hole and firm around gently. Make sure not to bank the soil up around the collar of the tree as this can cause problems.
If you’re planting in dry weather, water well and regularly for the first few months. The same goes for spring and summer planting. Make sure to keep an eye on your young tree and increase watering if there are extended periods of hot or dry weather. If you’re planting in autumn, you may only need to water your tree a little. We also stock a range of irrigation kits, suitable for a variety of planting schemes.
Once planted, it is important to keep the area free of competing weeds and grass for the first couple of growing seasons. Using a glyphosate based weed killer or installing mulch matting and bark chips will aid in this. Do not simply mow the grass around the area as this will only encourage it to grow more vigorously. If you know your area is prone to rabbits, we would advise using a rabbit guard.
Pruning Advice for Sequoiadendron Giganteum trees
Giant Sequoia trees do not require a lot of pruning. Simply remove any dead, diseased or awkwardly placed branches from your Sierra redwood tree as and when you see them.

Supplied Size: Height measured from the top of the pot.
