If trees are not correctly secured they will rock in the planting pit. Each time you mow, the grass will grow back more vigorously and strimming invariably leads to lacerated trunks. Mowing or strimming is NOT an answer to the problem.Weed killer needs to be applied each year for the first 3 years, preferably when the tree is dormant, or just once before applying a mulch mat. Organic weed killers usually do not kill roots. Weed killer is very effective, however it is harmful to the environment.Be careful not to allow the woodchip to touch the stem as it can cause rot. After clearing the ground around the tree, firmly fit the mat by tucking the edges into the soil and put a thick layer of bark mulch on top of this. Mulch mats are an effective way to stop grass and weeds, although they will require a careful eye to make sure they continue to work.

It is vital that for at least 3 years after planting your tree or hedge has a circle or strip one metre wide completely free of grass. When trees are first establishing, the grass roots would be at the same level as the tree roots and are far more efficient at taking up water and thus choke the tree. One of the most common causes of lack of water is competition from grass. In hot dry spells give the equivalent of 2 bucketfuls every three days. It is essential throughout the spring and summer, to give a heavy enough watering to enable the water to penetrate right down to the deepest root level of the tree. The main reason that plants die within 12 months of having been planted is lack of water. It is known in America amongst other names as Big Tree and Mammoth Tree.įor the continued healthy growth of your trees, shrubs or hedging it is vital that you follow the advice below. It was once thought to be the world’s longest living species with specimens aged at well over 3000 years, but the title is now commonly thought to belong to the bristle-cone pine, also native to North America, where specimens have been aged at over 4000 years. Originating from the Sierra Nevada in North America, the species was first officially planted in Britain in 1857 on the Duke of Wellington’s estate in Stratfield Saye in Hampshire and was given the name Wellingtonia in his memory.

Grow in well-drained soil in full sun or light shade. This tree certainly makes a statement and would make a perfect landmark either planted on its own, as a group, or in an avenue and the need for a large area goes without saying. These long-lived giants often feature in the grounds of grand country houses and parklands. On established trees the branches sweep elegantly downwards then up towards the tips, with small green and brown cones amongst the fragrant fronds of scale-like leaves. This bark is thick and fibrous with soft ridges. The Wellingtonia has a distinct narrowly conical shape, pointed at the top, with attractive reddish brown bark that glows in the evening sunlight. Brown cones 3/4 inch long ripen each year.Reaching altitudes of well over 30m (100ft) these towering giant conifers grow rapidly to their truly awe-inspiring size. Soft, bright green needles, about 3/4 inch long, appear in early spring, then turn pinkish brown before falling in the autumn. On a large lawn, they can attract attention not only for their history but for their foliage. and elsewhere-young plants grow 3 feet or more a year. Presumably they will eventually attain a similar size in the U.S. Mature trees in China are broadly conical and grow about 100 feet tall from thick buttressed roots. The seeds collected were shared with other botanical gardens around the world, and this deciduous conifer is now widely available.
A Boston arboretum sent a special expedition to the area. One year later, Dawn Redwood was discovered alive and well in the remote village of Motao-chi in the Chinese province of Szechwan.
At the time, the tree was thought to have been extinct for perhaps a million years. Dawn Redwood (Metasequoia glyptostroboides) was unknown until about 60 years ago, when it was discovered in the form of fossils collected by paleobotanists.
