A. Clearing out trees
of this nature can be a difficult and arduous task, but can be done. It
helpful to know what type of tree is growing before you set out to chop it
away. The reason for this is because of the variety of root systems you
may encounter. Some trees have deep strong roots that may take more than a
few times to rid, whereas a tree with shallow roots may be easier to
clear. For example, Hackberry trees have very deep root systems and live
oak trees have less deep roots. Look around the garden area and see what
type of trees are growing. This is most likely what is in the garden
area. Timing is also an issue to consider, it will be easier to dig up
roots in the dormant season, than in the spring when they are growing more.
The first way to rid the saplings is to cut the trunk down to the ground and dig out the roots. This is an arduous task but is the least toxic and it will also help to work the soil for the garden. You may need to use an ax and a hoe to manipulate the roots. Keep in mind that if you do not get all the roots at first, you have made a very good dent in future growth, because you have done serious damage to the root system. It may be necessary to hack and dig away at the roots for several days in a row.
Another way to rid the saplings is to use an herbicide that will kill the root systems, like Finalie. This should be used with discretion because it is an herbicide and will kill other plants in the area. You may try cutting the trunk and then applying the herbicide to the freshly cut trunk. Again be cautious with herbicides. In the early spring you may try applying an herbicide to the new growth of the sapling. Be careful when applying herbicides and apply on non-windy days. It is necessary to wait to plant any vegetation until the herbicide has worn off, or else it will kill whatever is planted. As always, read the labels and use with caution.
Third, you may consider a stump removal product. This requires a hole to be drilled in the center of the trunk, (after chopping it down) and place the stump removal down the hole. Cover the hole with plastic or some water proof material so rain does not dilute the product. Remember to read the directions carefully and use caution using chemicals.
Lastly, you can call a tree service to help you remove the saplings. This may be expensive and ask their technique on removal.
