Appearance
Characteristics
- Young seedling oak trees have tap roots. Unlike the fibrous roots that grow in shallow soil around the base of a plant, tap roots grow deep into the soil and originate directly beneath the tree's trunk. Oak tree root systems develop best in slightly acidic, well-draining soil with ample oxygen and no obstacles such as other large trees, underground pipes and buildings. Do not plant oak trees in p…
Ecology
- Oak tree roots have a symbiotic relationship with a type of soil fungi, called mycorrhiza, which live in most soils. Of the two types, oak tree roots depend on ectomycorrhizae mycorrhiza for survival, as it forms a physical sheath around the root and protects it from fungi causing disease. These fungi share the nutrients they collect with the roots...
Risks
- In addition to watering an oak in times of drought, it's important to avoid injuring the roots when you work around the tree, especially if you're digging or using power tools. Mowing and digging out weeds can injure an oak's roots and break the bonds mycorrhiza have to the roots. Exposed and damaged roots are more vulnerable to diseases and pests. In addition, disturbed soil encour…
Health
- Soil compaction can reduce the health and vigor of an oak tree and its root system. People constantly walking near the tree or driving or parking over the root zone can cause the soil to become compressed and dense and lacking the necessary air pockets. Compacted soil drains poorly and doesn't allow enough air to reach the roots, compromising the oak tree's health. Intro…
Prevention
- You can start a healthy oak tree with a strong root system from a mature, plump acorn that you collect yourself and keep moist with organic material. If you want to transplant oaks, it is best to do it when the tree is less than 3 years old as older oaks do not transplant well because of their tap roots. For trees less than 2 years old, the root crown should be above the soil when you tran…
