Growing trees is not so simple

怎么才能让小树健康成长呢？

　　THERE is a lot more to planting a tree than just putting it into the ground%26#46;

　　Even before planting the tree you need to decide which kind of tree to plant%26#46;

　　And, that depends on the kind of weather and soil (土壤) you have%26#46;

　　A young tree can die if the weather is too hot or too cold%26#46; So, spring or early autumn are the best times of year to plant trees%26#46;

　　The hole for the tree must not be too deep or too small%26#46; If it is too deep air cannot get to the roots%26#46; If it is too small the roots don’t have enough space to grow%26#46;

　　Newly planted trees should be watered straight away%26#46;

　　They should also be watered at least once a week and more often in summer%26#46;

　　But they must not be watered too much%26#46; If the tree is watered too much air cannot get to the roots and the tree might die%26#46;

　　Putting small pieces of wood around the bottom (底部) of a newly planted tree can help it to grow%26#46;

　　Doing this helps air get to the tree’s roots and also makes sure they don’t get too dry%26#46;

　　To help the tree stand up straight you can put a stake (桩) into the ground next to the tree and tie the tree to it%26#46;

　　The tree mustn’t have the stake for too long or it will be weak when it grows up%26#46;

　　To protect (保护) the tree’s bark (树皮) from the sun and wind you can wrap (包) special paper around the tree%26#46;

　　You have to change the paper every spring to make sure the bark doesn’t have any disease%26#46;
