Best Trees For Lawns
Most gardeners know the fact that it is not easy to find the best trees for growing along with the lawns for a number of reasons. If you have several trees in your garden and you are planning to cultivate a patch of attractive lawn underneath, you’d better follow some basic guidelines to make it easier.
The two main reasons for the interference of high trees with the lawns are the shade provided by the tree foliage and the emergence of tree roots on the ground. The heavy shade built by the foliage block the sunlight which is essential for the energy generating process of the lawn. The roots appearing on the surface of the ground will compete with the lawn for the nutrients. They will also turn the soil into acidic which is not suitable for the growth of the lawn. This can explain why so much moss appears on the lawn under a tall tree with dense foliage. So, you should do something for your lawn if you discover the above facts which affect the growth of your lawn.
If you find some trees roots emerging on the surface of the ground for water and nutrients you provided for your lawn, you should insert some pipes into the soil for a certain depth and put water and fertilizer into the pipe to let them perforate into the deep location of the soil. This can effectively guide the tree roots to grow into a deeper location, and thus avoid them emerging to the ground to compete the nutrients with the lawn. Also, you need to apply more water and fertilizers for the lawn under a tree because the grass roots may compete with the tree with the above resources. It is a good practice to provide the fertilizers once for every two months. Moreover, the soil under a tree is likely to be acidic which is not good for the lawn cultivation. Some amendments should be applied to the soil to make the PH value neutral.
Regarding the requirement of the trees, you should choose some tree species which can easily grow together with the lawn underneath. The deciduous trees can shed their leaves in autumn and winter days, and thus enable the sunlight to reach the lawn for a few months. Also, the trees should be able to tolerate the frequent irrigation applied on the lawn. In this case, some tree species like oaks cannot be a good option. Some trees will produce substances which will affect the growth of the grass underneath like eucalyptus or walnut trees. These trees should not be your choices either. Moreover, the suitable trees should not generate heavy shade underneath. So, some trees with sparse foliage can be chosen as a candidate for your lawn.
