![]() ![]() Roots not firmly in contact with the soil are unable to take up moisture and nutrients, resulting in die back or death of the tree. 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. Maples tend to bleed if pruned at other times, which can be unsightly.įor the continued healthy growth of your trees, shrubs or hedging it is vital that you follow the advice below. What time of year should I prune? Prune in winter (November to January) when the plant is dormant. Remove these fully by cutting the stems flush with the main stem. Once you have an established tree, you need only remove the damaged and diseased stems. The Crimson King cultivar of Acer platanoides requires very little maintenance. This cultivar was found in Belgium in 1937 when it was selected from a crop of seedlings grown from the tree Acer platanoides ‘Schwedleri’ (Yet another selection from Norway Maple.) Also a good choice for cities as it copes well with pollution. It is a very hardy tree that will tolerate a lot of wind. It requires full sun or light shade and will grow on most soil types, with the exception of overly acidic sandy soils. It is a great tree for screening and contrasts well with trees of bright foliage such as Acer platanoides 'Drummondii', and for this reason these two trees are often planted together. The most noticeable and striking feature are its stunning deep purple 5 lobed leaves, that are of classic maple shape. If given the space it can grow to more than 15m (50ft) in height with an oval shaped crown that can almost be as wide as it is tall. ![]() In answer to that, the 'many babies' could be the progeny of one or both the trees, there's no way of knowing - most likely from both.ACER PLATANOIDES CRIMSON KING – Crimson Leaved MapleĪ ruby red to purple leaved cultivar of the Norway Maple, Acer platanoides Crimson King is a fast growing medium sized tree. Sorry, I didn't realise you'd commented - missed it altogether, didn't know it had been added into the question either, just happened to notice editor's comment above. Some Acer flowers actually change between male, female and hermaphrodite (and possibly back again) over time, but there's certainly no need to worry whether you have a male or female tree for either reproductive or appearance purposes.Īcer rubrum is considered to be divided between male and female trees, but the flowers are either unisexual or bisexual on both, so for reproductive purposes, its not an issue - more reading about that here if you're curious Generally, Acers are capable of fertilizing their own flowers without any other Acer tree nearby, if its lots of fertile seeds you're looking for. ![]()
