Crimes against trees, don't be guilty of committing these planting offences!
Whatever tree you plan to plant
(and every garden should have at least one), the most important gift you can donate is to plant it correctly. This will help to prevent major problems in the future, including dangerous loss of tree limbs and indeed the demise of the entire tree together with the hazards this poses to nearby people and property. Around 80 per cent of unstable trees
have been incorrectly planted, leading to a problem in the root zone.
Love trees? Plant one in your garden and reap many rewards!
Crime number 1: are you planting too deeply?
Its vital to plant at the correct depth
and many trees, even those planted by experienced gardeners, are too deep. Its far preferable for the tree to be planted too shallowly rather than deep. Why?
Most of a trees roots are located in the top 60cm of soil where it can soak up three things that are essential: moisture, oxygen and warmth. Premature decline of trees will occur as a result of the stem being plunged too deeply into the ground where there is less oxygen and it is colder and drier. The roots will find it difficult to extend sideways in order to stabilise the entire tree.
STOP! This tree is being planted too deeply. It's so simple to get it right at the planting stage.
Root balling of trees tends to exaggerate this problem as the root ball has already raised the compost level artificially high and it therefore looks as if it needs to go deeper underground. In fact it is believed that most root balled trees are planted at least 13cms too deep. Best practice: when planting a root balled tree, ensure the root ball sits a few centimetres proud of the soil so it can gently settle back down as nature takes its course. Root anchors, although great in many ways, can exacerbate the problem if the tree has been planted too deeply - it will have no hope of finding a better level.
This shows a rootball fixing strap available from Platipus (www.platipus-anchors.com). There are many different types of underground anchors and fixing systems.
Crime against trees number 2: the hole truth
Hole depth need not be very great for a tree planting ceremony its the width that is the crucial factor. Before planting a tree you need to loosen the surrounding soil and ensure the roots can spread out sideways.
Don't feel you have to go down too deeply. Some people believe it's beneficial to add a teaspoon of sugar
in the planting hole. Others never fail to use mycorrhizal fungi
which effectively extend the root areas of plants and allows them to make the most of the nutrients available to them.
A teaspoon of sugar helps the tree go down... but not too deeply!
Crime against trees number 3: it's a stake-out
at the planting stage can damage a tree and can shorten its life. Some people kill trees with kindness. Their stakes are too tall and the ties are too secure. A tree needs to be able to rock backwards and forwards in the wind. This encourages the roots to develop as the plant learns how to stabilise itself within the elements. Use a low stake, where possible, and only keep it in place for two to three years.
Poor tree! The stake and tie that was once put it to help it grow has effectively maimed the tree and forced it to grow off-centre.
Crime against trees number 4: water, water everywhere... or nowhere
Watering regimes are responsible for a lot of tree fatalities. Some people water excessively after planting and they simply wash away all the goodness. Trees can actually drown and you don't want to see a tree sitting in a puddle of water for too long - unless it's a bog dweller. It stands to reason that under-watering is also a killer. This is a major problem when planting container-grown trees during the summer. They will need regular watering throughout the hot months until they have established.
Don't let your trees drown! Too much water is just as harmful as too little.
Which trees to plant in your garden?
If you are planning to plant a tree in your garden, make it a good one! This means that it should serve several functions, not just one. The perfect tree will provide a bit of shade and shelter; it will have plenty of attraction for wildlife; it might produce fruit, and of course it will look lovely too. Some trees are better than others at multi-tasking.
Whatever you choose
, make sure you plant it correctly, position it so that the shade falls where you want it, and then enjoy it!
Trees are wonderful but make sure you choose the best one for your garden.
Heres a guide to help you select the best tree for your particular purpose:
A weeping willow isn't suitable for a small garden!
- Make sure it fits the space available. Look at the ultimate height. You dont want to be forever pruning a tree because its too big for the space available. Most people have small to medium gardens and they can only cope with a small to medium tree, up to 10m tall.
Ligustrum is a great little evergreen for screening purposes.
- Deciduous or evergreen? Does it need to screen something over the fence? If so, an evergreen will be sensible. A lollipop-shaped tree, i.e. with a standard stem, is a great choice for screening purposes. Chinese privet, Ligustrum lucidum, is a popular screening tree.
Fruit trees give you more than just shade and wildlife benefits, they provide delicious fruit too.
- It is important to have a crop from your tree? Fruit trees such as apples, plums and pears can be used for shade, beauty and wildlife too.
Prunus 'Amanogawa' is just one example of a fastigiate, or upright, tree for a small space.
- Consider the shape. Some trees spread as wide as they are tall. If you have only a slim space available, go for a fastigiate, or upright shape. Prunus Amanogawa or Pyrus Chanticleer are popular choices.
The snowy mespilus, Amelanchier, is a great tree for a small garden.
- Do you want something for all seasons? Some trees have spring blossom, attractive foliage, fruits, autumn leaf colour, plus a good winter structure. Amelanchier lamarckii is a brilliant choice.
A miniature weeping tree is often a popular choice for a small garden.
- Perhaps a weeping form would suit your space. Everybody knows a weeping willow but it is only suitable for a large garden and does like to be near water. There are alternatives such as a weeping pear, Pyrus salicifolia Pendula and several different varieties of weeping cherry trees.
Hawthorn is a great choice for a small garden.
- Want a tree with berries for birds? You cant go wrong with a hawthorn, Crataegus. It also provides lovely spring blossom and its a great nesting tree too.
Acer griseum has a wonderful bark and this is a major part of its attraction.
- Perhaps its the bark that pleases you most? If so, there are trees with amazing stem colour and texture including the lovely paperbark maple, Acer griseum; the Chinese red birch, Betula albosinensis and Prunus serrula with its rich mahogany colour stem.
