Fig Tree Roots
Fig trees are large landscaping trees which can provide great ornamental values for your garden. Most fig trees can grow more than 50 feet in height with an even wider spreading canopy. They have dense green foliage in summer which will generate heavy shade which makes it not easy for plants to survive underneath. Generally, this large tree species needs a robust root system underground to support its massive crown above the horizon.
Like most landscaping trees, fig trees like well-drained soil conditions which can enable the tree root to breathe freely. Insufficient air supply will weaken the ability of the fig roots and affect the absorption of nutrients and water for the tree body. Fig tree roots can be infected by some pests like gophers and nematode which feed on fig roots. Young fig trees can be killed quickly if heavily infected by these pests. Some gardeners even plant fig trees in containers to avoid the pest infection. Some pesticide can help to kill these pests and some mulching can also be helpful.
Fig roots are fast-growing and sometimes are considered as invasive to buildings and foundations. The roots of most fig trees will go far beyond its canopy, so you should leave adequate space before planting a fig tree for future. Fig tree roots are often close to the surface of the soil to facilitate the absorption of the water and nutrients. You should provide adequate water for your trees in hot summer days to avoid any water stress. Some mulching materials can also help to reserve water for the roots.
