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. The largest specimen in the UK currently 25m (80ft) tall.įor the continued healthy growth of your trees, shrubs or hedging it is vital that you follow the advice below. It is now widespread in parks and gardens throughout the world. In 1948 the Arnold Arboretum of Harvard University sent an expedition to collect seeds and, soon after, seedling trees were distributed to various universities and arboreta worldwide for growth trials. The genus Metasequoia was first described as a fossil from the Mesozoic 65 to 200 million years ago, however in 1943 a small stand of an unidentified tree was discovered in China in Lichuan County, Hubei these were not studied further until 1946 and only finally described as a new living species, Metasequia glyptostroboides in 1948. The Dawn Redwood is in some ways a botanical oddity as it is the only living member of it genus. In this respect it is also similar to Swamp Cypress (Taxodium distichum) with which it also shares a liking for wet even boggy ground.ĭawn Redwood will grow in most situations, it will grow best in deep loamy moist soils, it does not like dry soils but will cope well with waterlogging even to the extent of growing in standing water. However, this mistake should only be made in the summer for unlike its redwood cousin, the Sequoia, Metasquoia is a deciduous conifer whose needles turn a reddish-brown before falling off in the autumn. The leaves which are short, broad needles, could be mistaken for those of the Yew. ![]() The Dawn Redwood has the familiar conical coniferous shape, with sparse upward sweeping branches giving the tree a narrow form. After the tree drops its foliage in fall, plant it in the garden.METASEQUOIA GLYPTOSTROBOIDES – Dawn Redwood Water the plant with 2 inches of water each week for the rest of the season.When roots have developed, transplant the cutting into a 1-gallon nursery container filled with a mixture of equal parts loam, sand, and compost.It may take two or even three months for anchoring roots to develop. Test for roots after one month by tugging on the branch to see if roots are holding it in place.Placing the pot on a heated mat may speed up the rooting process. Place the pot in a sheltered outdoor area and keep the sand constantly moist.Insert the branch, cut side down, into the pot of sand, burying it to about 1/2 its length.Coat the cut end and the scraped area with acid rooting powder. ![]() Scrape off a segment of bark about 1/2-inch long and 1/4-inch wide near the cut end of the branch but take care not to damage the leaf node. Angle the cut end at 45-degrees, just below a leaf node. An ideal cutting will have a stem about 1/4-inch thick.
